The present disclosure relates generally to display calibration and, more particularly, to customizing display color settings for personal color preferences. Cross References to Related Applications

This application claims the benefit of U.S. Provisional Application No. 63/230,227, filed August 6, 2021, which is hereby incorporated by reference in its entirety.

Traditionally, color displays have been characterized by colorimetric color reproduction. A simple display color characterization method is to characterize a display as an sRGB display, that is, a display is characterized to obtain RGB input signals and display the RGB input signals on the screen in a colorimetric manner. But conventional color standardization does not take into account personal color preferences.

Description Customize display color settings and feature definitions for personal color preferences. A device generates color preferences customized for a user of the device. Customized processing of global color preference and memory color preference. Color preferences are user-customized and describe the user's preferences for how colors are presented on the device's display.

In some specific examples, a method is described. Generate a first interface for customizing the value of the global color preference. Feedback is received from the user via the first interface. Feedback describing custom global color preferences. Generate a second interface for customizing memory color preferences. Feedback is received from the user via the second interface. Feedback describes custom memory color preferences. Use custom global color preferences and custom memory color preferences to generate color preferences. Color preferences describe user preferences for how colors are presented. The color preference setting is associated with user settings of the user, wherein the visual content is presented on the display according to the color preference setting.

In some embodiments, a non-transitory computer-readable storage medium is described. The non-transitory computer-readable storage medium includes stored instructions that, when executed by a processor of the device, cause the device to: generate a first interface for customizing global color preferences. The instructions further cause the device to receive feedback describing the customized global color preference from the user via the first interface, and generate a second interface for customizing the memory color preference. The instructions further cause the device to receive feedback describing the customized memory color preference from the user via the second interface, and generate a color preference setting using the customized global color preference and the customized memory color preference. Color preferences describe user preferences for how colors are presented. The instructions further cause the device to associate a color preference setting with the user's user settings, wherein the visual content appears on a display of the device according to the color preference setting.

In some embodiments, an apparatus is described. The device includes a display and a controller. The display is configured to display visual content according to color preferences. The controller is configured to generate a first interface for customizing global color preferences, wherein the first interface is presented via the display. The controller is configured to receive feedback from the user describing the customized gamut color preference via the first interface. The controller is configured to generate a second interface for customizing the memory color preference, wherein the second interface is presented through the display. The controller is configured to receive feedback from the user describing the customized memory color preference via the second interface. The controller is configured to generate a color preference setting using the customized global color preference and the customized memory color preference, wherein the color preference setting describes a user's preference for how colors are presented.

Description Customize display color settings and feature definitions for personal color preferences. Devices (eg, computer monitors, tablets, wearable devices, communication systems, etc.) present to users an interface by which feedback can be provided to customize the user's global color preferences. A global color preference describes display parameters (eg, contrast) that apply to all colors. The device also presents to the user an interface by which feedback can be provided to customize the user's memory color preferences for one or more memory colors. Memory color preferences describe the standard set of colors for different types of objects (eg, sky, grass, trees, faces, etc.) that a human observer acquires through his experience with instances of that type. A memory color can be the commonly perceived color of an object, which can depend on the living environment or culture (eg, the frequency of colors used can correspond to natural colors prevalent in the environment or can vary based on cultural meanings). The device uses the feedback to generate color preferences customized for the user of the device. Customize display parameters for global color preferences (eg, contrast) and memory color preferences for one or more specific standard colors (eg, hue). Color preferences are user-customized and describe the user's preferences for how colors are presented on the device's display.

It should be noted that a device may have multiple users, where each user has associated user settings. The device can associate the user's color preference setting with the user's user settings. Therefore, when a specific user logs in to the device, the device can retrieve from the user's user settings (local storage or remote storage) (for example, store social graphs from the local terminal, etc.) customized for the user color preferences, and then present the visual content on the display of the device according to the retrieved color preferences.

Traditional display color characterization is based on colorimetric color calibration. Depending on the display technology, color characterization methods are slightly different. CRT display color characterization is based on measurements of black, white, and primary colors, and then a gamma curve and 3x3 matrix are derived for colorimetric transformation. In LCD and LED displays, due to more nonlinear tone characteristics and inter-channel dependencies, more complex models can be applied for colorimetric characterization. If an ambient sensor is available, ambient light adaptation can be applied to adjust the display white point and contrast to improve color appearance. Finally, the display panel calibration block will calibrate the panel variation so that the performance of each panel is as close as possible to the gold panel. In the TV display and mobile display markets, Saturation Boost has been applied to increase color saturation and extend the color gamut beyond sRGB. However, deviations from defined colorimetric characteristics are not based on user color preference, but are enforced during manufacture. In contrast, described herein is an apparatus that performs the steps of color profile definition and personal color preference enhancement.

Embodiments of the present invention may include implementation by or in conjunction with an artificial reality system. Artificial reality is a form of reality that has been modified in some way before being presented to the user, which may include, for example, virtual reality (VR), augmented reality (AR), mixed reality (MR), hybrid reality , or a combination and/or derivative thereof. Artificial reality content may include fully generated content or generated content combined with captured (eg, real world) content. Artificial reality content may include video, audio, haptic feedback, or some combination thereof, any of which may be presented in a single channel or in multiple channels (such as stereoscopic video that creates a three-dimensional effect on the viewer). In addition, in some embodiments, an artificial reality may also be associated with an application, product, accessory, service, or some combination thereof for generating content in an artificial reality and/or otherwise for use in an artificial reality . Artificial reality systems that provide artificial reality content can be implemented on a variety of platforms, including wearable devices (e.g., headsets) connected to a host computer system, standalone wearable devices (e.g., headsets), mobile device or computing system, or any other hardware platform capable of delivering augmented reality content to one or more viewers.

FIG. 1 is a block diagram showing a system 100 according to an example of one or more embodiments. The display system 100 can customize display color settings according to personal color preferences. The customized display color settings may then be used by one or more devices of the display system 100 to present content to the user. In the specific example of FIG. 1 , the display system 100 includes a device 110 that is optionally coupled to a device 120 and/or a communication server 125 via a network 130 . Some specific examples of display system 100 have different components than those described here. Similarly, in some cases functionality may be distributed among components differently than described herein.

Network 130 may comprise any combination of local area and/or wide area networks using wired and/or wireless communication systems. In one embodiment, network 130 uses standard communication techniques and/or protocols. For example, the network 130 establishes a secure communication link between the one or more client devices 615 and the communication system 620 using the ultra-wideband (UWB) protocol. In other examples, network 130 uses data such as Ethernet, 802.11 (WiFi), Worldwide Interoperability for Microwave Access (WiMAX), 3G, 4G, 5G, Code Division Multiple Access (CDMA), Digital Subscriber Line (DSL) , BLUETOOTH®, Near Field Communication (NFC), Universal Serial Bus (USB), or any combination of protocols to establish a communication link. In some embodiments, all or some of the communication links of network 130 may be encrypted using any suitable technique or techniques.

The device 110 customizes display color settings according to personal color preferences. Device 110 may include a display and or control an external display (eg, an LCD monitor). Device 110 may be, for example, a computer, tablet computer, smartphone, communication system (eg, as described below with respect to FIG. 6 ), television, headset, smart watch, control, and/or some other device including a display. . Device 110 includes a display 140 and a controller 150 , and optionally includes an ambient light sensor (ALS) 160 .

The display 140 presents images according to instructions from the controller 150 . The display 140 can be, for example, a liquid crystal display (e.g., light emitting diode backlit LCD, thin film transistor LCD, quantum dot display), a waveguide display, a light emitting diode display (e.g., organic light emitting diode display, active matrix organic light emitting diode Polar display, etc.), some other device that presents an image, or some combination thereof. Display 140 presents images according to the color preference settings of the user of device 110 (and more specifically, display 140 ).

ALS 160 is configured to determine the ambient light properties of a local area of display 140 . The ambient light property is the value of brightness in one or more color channels (eg, red, green, blue) of a local area. For example, an ALS may include pixels for detecting red light, green light, blue light, infrared light, ultraviolet light, broadband (eg, no filter), or some combination thereof. Ambient light properties can be used to determine white balance under different lighting conditions (for example, natural daylight versus fluorescent lighting).

The controller 150 controls the components of the device 110 . In the specific example of FIG. 1 , the controller 150 includes a data storage area 170 and a color customization module 180 . In some embodiments, controller 150 may reside on an external device. For example, display 140 may be a display that is separate from, but communicatively coupled to, controller 150 . Some specific examples of controller 150 have different components than those described here. Similarly, functionality may be distributed among components in different ways than described here. For example, some functions of the controller may be performed outside the device 110 . The user may elect to allow controller 150 to transmit color preferences determined on device 110 to systems external to device 110 (e.g., device 120 and/or communication server 125), and the user may elect to control access to any such data access privacy settings.

The data storage area 170 stores data for use by the device 110 . The data in the data storage area 170 may include one or user settings, color preference settings of one or more users, global color preferences of one or more users, memory color preferences of one or more users, helpful A customized image of global color preferences, a customized image that facilitates memory color preferences for one or more different standard colors; or any combination thereof. Color preferences are user-customized and describe the user's preferences for how colors are presented on the device's display (eg, display 140 ).

A global color preference describes display parameters that apply to all colors. Global color preference display parameters may include, for example, contrast, color saturation, brightness, some other display parameter applicable to all colors, or some combination thereof. Customizable images that facilitate global color preferences can depict content using a variety of colors, brightness and contrast. In selecting these global parameters, the user can select a familiar image that exhibits modifications in brightness, contrast, and color saturation. In a first example, an image with shadows, highlights, and midtones can be used to select global parameters for brightness and contrast adjustments. In a second instance, images with multiple colors from objects or environments such as grass, trees, sky, and building materials (e.g., metal, clay, wood, brick, etc.) can be selected for saturation and/or hue adjustments The global parameter. Display parameter values for a global color preference may be said to be global because the display parameter values apply to all colors. For example, contrast values may be referred to as global contrast values; saturation values may be referred to as global saturation values; and brightness values may be referred to as global brightness values.

Memory color preferences describe the standard set of colors for different types of objects (eg, sky, metal, skin, grass, tomato, etc.) that a human observer acquires through his experience with instances of that type. For example, most human observers know that tomatoes typically have a reddish color; this knowledge about the standard color represented in memory constitutes the memory color. Standard colors may include, for example, skin tones, green leaves, blue skies, red objects, some other standard color, or some combination thereof. It should be noted that certain different standard colors may be more important in some cultures. For example, red is extremely important in Asia, so a memory color preference may include red items in the Chinese market, and may not include red in other markets where red is less important (eg, Norway). Each memory color preference standard color can be described by a hue value, a saturation value and a brightness value. Customized images that help remember color preferences are associated with specific standard colors. For example, if the standard color is blue sky, a customized image that would aid in remembering the color preference for blue sky may include, for example, an image that includes mostly blue sky (eg, at least 50% of the image is sky). In a similar manner, if the standard color is green foliage, customized images that would aid in remembering color preferences for green foliage may include, for example, images that include most vegetation (eg, forests, fields, shrubs, etc.).

It should be noted that the actual implementation of color preferences depends on the display color scheme. For example, if the display hardware or software supports three-dimensional (3D) color look-up tables (LUTs), the color preferences can be generated as 3D LUTs and merged with existing 3D LUTs for display color transformation. If the display color transformation is implemented in a one-dimensional (1D) LUT, two-dimensional (2D) LUT, or a combination of 1D and 2D LUTs, the color preference settings may be converted to 1D and/or 2D LUTs to approximate the color preference transformation. A color preference engine can be developed using a graphics processing unit (GPU) or a hardware implementation for dedicated color preference transformation.

The color customization module 180 is configured to generate an interface by which a user can customize global color preferences. The interface may be a Graphical User Interface (GUI) presented via the display 140 . In other specific examples, the interface can be a combination of the display 140 and other controls (eg, physical buttons). The color customization module 180 can capture images of scenes to facilitate customization of global color preferences. The system can maintain a default set of images for preference adjustment, and also have the option for users to select their own images. Images covering shadows, midtones, and highlight image content can be used for brightness and contrast adjustments. Images that cover rich colors with various saturations and hues can be used for saturation and hue adjustments. Carefully selected images exhibiting the effect of each global adjustment feature can be used to adjust the overall global color preference property, or individual images can be used to adjust each of brightness, contrast, saturation, and hue, or multiple images can be used to adjust properties. The color customization module 180 can instruct the display 130 to display images using initial values and/or previously set values for display parameters (eg, contrast, color saturation, brightness). The interface presents the generated image via the display 140 . The interface uses information from and/or may include one or more controls that the user can use to adjust display parameters associated with global color preferences, specifically contrast , color saturation, lightness, or a combination thereof. The one or more controls can be, for example, a touch screen with soft buttons, sliders, etc., a physical interface on the device (eg, buttons, dials, etc.), or some combination thereof. When the user adjusts the value of a display parameter (eg, contrast), the interface dynamically adjusts the image being presented for display according to the adjusted display parameter. Once the user's feedback is complete (eg, the user hits the next button), the display parameters are updated according to the adjusted display parameters. In this way, the user is able to customize global color preferences to align with the user's preferred presentation. The received feedback describes the customized global color preferences specific to the user. An example interface for customization of values for global color preferences is described below with respect to FIG. 3 .

The color customization module 180 is configured to generate an interface by which the user can customize and remember color preferences. The interface may be a GUI presented via display 140 . In other specific examples, the interface can be a combination of the display 140 and other controls (eg, physical buttons). In some embodiments, the interface is similar to that used to customize global color preferences. The color customization module 180 selects the first standard color (for example, green leaf color preference) in the standard color set of memorized color preference. Color customization module 180 may retrieve images representing scenes of selected standard colors rendered using initial values and/or values previously set for display parameters (eg, hue, saturation). The interface presents the generated image via the display 140 . The interface uses information from and/or may include one or more controls that a user can use to adjust the value of a display parameter. The one or more controls can be, for example, a touch screen with soft buttons, sliders, etc., a physical interface on the device (eg, buttons, dials, etc.), or some combination thereof. When the user adjusts the value of a display parameter (for example, hue), the interface dynamically adjusts the image being presented for display according to the adjusted display parameter. Once the user's feedback is complete (eg, the user hits the next button), the display parameters are updated according to the adjusted display parameters. In this way, the user is able to customize the memory color preference to align with its preferred presentation. The received feedback describes the user-specific customized memory color preference. An example interface for customization of remembering color preferences is described below with respect to FIG. 4 .

The color customization module 180 repeats the above process of customizing the memory color preferences of different standard colors. For example, if the interface is presenting an image of a green leaf color preference, the color customization module 180 may perform similar customization for a blue sky color preference, where an image representing a blue sky is captured and displayed according to the current display parameter set. And, as above, when the user customizes one or more values of display parameters (e.g., hue, saturation, and/or brightness) of the rendered image, the interface dynamically adjusts the proper rendering to display the image according to the adjusted display parameters. of the image. In some embodiments, the color customization module 180 repeats this process until each of the memorized color preferences is customized.

It should be noted that the color customization module 180 can generate and render additional images as part of the customization for a given standard color for a remembered color preference (eg, red objects, green leaves, blue sky, metal, etc.). For example, if the standard color is skin color, the device may generate multiple images each representing a person with a different skin color (eg, an image of a white female, an image of a black male, an image of a Chinese male, an image of a Latina female, etc.). The color customization module 180 may collect user feedback on customized images of standard colors rendered for use in remembering color preferences.

In the above description, the global color preference is customized first, and then the memory color preference is customized. In other embodiments, some or all of the remembered color preferences for the standard color set may be customized prior to the global remembered color preferences.

The color customization module 180 is configured to use custom global color preferences and custom memory color preferences to generate color preference settings. Color preferences describe user preferences for how colors are presented.

The color customization module 180 is configured to associate color preferences with the user's user settings. In this way, visual content is presented by display 140 according to the color preference settings on device 110 . In some embodiments, the color customization module 180 can upload the color preference settings to the communication server 125 via the network 130 (eg, so that the color preference settings can be used later by different devices associated with the user). In some embodiments, controller 150 may retrieve color preference settings from communication server 125 and/or device 120 (with permission of the user) in response to receiving login credentials (eg, user identification information) from the user.

Communication server 125 maintains color preference settings for one or more users. The communication server 125 may be, for example, a social networking server, a cloud server, an entertainment provider server, some other server that maintains or is communicatively coupled to some other server that maintains color preference settings, or some combination thereof. Communication server 125 may maintain these color preference settings, eg, as part of a social graph. Communication server 125 may receive a request from a device (eg, device 120 and/or device 110 ) for color preference settings associated with a requesting user of the device. The communication server 125 validates the request. In response to the request being authenticated, the communication server 125 may retrieve the requesting user's requested color preference and distribute the requested color preference to the requesting device as permitted by the user.

In this way, once a color preference is generated for a user, the color preference can be retrieved and used by other devices used by the user without having to regenerate color preferences on those other devices. Also, since some devices (eg, TV in a hotel, library facility, etc.) have multiple users, the described method facilitates each user having a different customized color preference setting. For example, after a user logs into the device, the display can retrieve color preference settings from the user settings and then present visual content on the display according to the color preference settings.

FIG. 2 is a graphical representation of a user's color preference setting 200 according to one or more embodiments. The color preference setting 200 includes a global color preference 210 and a plurality of memory color preferences 220 . Global color preferences 210 describe display parameters that apply to all colors. As illustrated, global color preferences include values for brightness 225, contrast 230, and saturation 240 (eg, color saturation). However, in other specific examples, the global color preference may also include the value of a certain display parameter applicable to all colors. As illustrated, memory color preference 220 describes three standard colors, specifically metallic color preference 250 , green leaf color preference 260 , and blue sky color preference 270 . Each of these standard colors is described by a corresponding set of values for display parameters such as contrast, saturation, and hue.

3 shows an example of a GUI 300 presented on a display of a device with controls by which a user may adjust global color preferences, according to one or more embodiments. The device may be, for example, device 110 . The GUI 300 includes an image area 310 and a control area 320 . Additional global color preferences may be included in GUI 300 . For example, although not depicted, a hue adjustment slider may be included for global hue adjustment.

Image area 310 presents one or more images to facilitate customization of global color preferences. As illustrated, image area 310 is presenting image 315 . It should be noted that the image is selected by the device to facilitate customization of the user's global color preferences. In some embodiments, images presented for adjusting global color preference can include different permutations of different images for adjusting global color preference. For example, a first image may be selected for its depiction of objects of multiple different colors to adjust the global color preference for contrast and saturation, and a second image may be selected for its depiction of illuminated objects against a dark background. Select to adjust the global color preference for brightness. Instead of or in addition to different images used to adjust different global color preferences, a single image can be used to adjust all global color preferences. Because the image is selected for global color preference adjustment, the image used in this step can demonstrate the effects of the global adjustment.

Control area 320 includes one or more controls for adjusting certain display parameters that affect the overall color preference and how image 315 is presented by the display. As shown, control area 320 includes contrast control 330 , saturation control 340 , and brightness control 350 . In other embodiments, different controls may be present (eg, only contrast control 330 and saturation control 340 , but no brightness control 350 ). A hue control may be included for global hue adjustment, but is not depicted in Figure 3. In this example, each of the controls (ie, contrast control 330 , saturation control 340 , and brightness control 350 ) is a slider. In other embodiments, some or all of the controls may take some other form (eg, a dial).

GUI 300 receives feedback from a user of GUI 300 via one or more controls. The device dynamically updates how to present the imagery 315 based on the feedback received. For example, increasing the amount of brightness via brightness control 350 causes the device to increase the brightness in image 315 . In this way, the user can customize and set the display parameters of the user's global color preference.

In some embodiments, once the user has indicated acceptance of the values of the display parameters controlled by the GUI 300, the GUI 300 can capture and present different images to facilitate customization of global color preferences. In some embodiments, GUI 300 can automatically set initial values for display parameters based on feedback received for previous images. Also, the GUI 300 may allow the user to further adjust display parameters via one or more controls.

In other embodiments, GUI 300 may sequentially receive feedback (ie, via one or more controls) for different images from the user, the feedback including the value of the display parameter. In some embodiments, after storing the set of display values for a particular image, the initial values of the display parameters are reset to default positions for each new image. As the image is displayed and adjusted, the results can be displayed on-screen for preview. After selecting a button (eg, an Accept or OK button) to accept the adjustment, the adjustment parameters can be recorded and applied. If another image is opened for further adjustments, the subsequently selected adjustments can be applied on top of the previously selected adjustments. As the cycle continues with additional images, adjustments can be accumulated. GUI 300 may include a button to reset one or more of the adjustments (eg, if the user is not satisfied with the adjustments).

The device may generate a display value for the global color preference using, for example, a weighted combination of the display values received for each image. The weighting of the displayed values may be based, for example, on characteristics of the image presented to the user at the time of acquisition. For example, the user may select different adjustment values in response to presenting different images, and the final color saturation value may be a weighted average based on the weights applied to the type of image used for adjustment. In some embodiments, color customization module 180 can classify images into types (e.g., based on objects depicted, changes in hue, amount of light captured within the image, etc.), and based on one or more of the images The weights to be applied to images are determined based on these properties (for example, images depicting more objects of different colors are weighted higher than images depicting a single object).

4 shows an example of a GUI 400 presented on a display of a device with controls by which a user may adjust a remembered color preference, according to one or more embodiments. The device may be, for example, device 110 . The GUI 400 includes an image area 410 and a control area 420 .

The image area 410 presents one or more images to facilitate customization of memory color preferences. As illustrated, image area 410 is presenting image 415 . It should be noted that the image is selected by the device to facilitate customization of the user's global color preferences. In this example, the memory color preference is for red objects. Thus, the device selects an image of a red apple to be presented as image 415 in image area 410 .

Control area 420 includes one or more controls for adjusting certain display parameters that affect the overall color preference and how image 415 is presented by the display. As shown, control area 420 includes contrast control 430 , saturation control 440 , and hue control 450 . In other embodiments, different controls may be present (eg, only saturation control 440 and hue control 450, but no contrast control 430, or a brightness control may be added for local brightness adjustment). In this example, each of the controls (ie, contrast control 430 , saturation control 440 , and hue control 450 ) is a slider. In other embodiments, some or all of the controls may take some other form (eg, a dial). The control area further includes a color area selector 460 to designate the portion of the image 415 to apply the effect of the adjustment control. The color region selector 460 is a drop-down menu that includes predetermined portions of an image as options. In some embodiments, GUI 400 may include tools for customizing the portion of image 415 to be adjusted (eg, a free-form marker to draw a shape around an area of the image that the user requests to adjust). A predetermined portion of the image 415 may be determined by the color customization module 180 (eg, applying an object classification algorithm, such as a machine learning model, or an image processing algorithm that divides the portion of the image by the hue of the color).

GUI 400 receives feedback from a user of the device via one or more controls. The device dynamically updates how to present the imagery 415 based on the feedback received. For example, increasing the amount of hue via hue control 450 causes the device to increase the amount of red hue in image 415 . In this way, the user can customize and set the display parameters of the user's memory color preference.

It should be noted that both the contrast control 430 and the saturation control 440 are also associated with setting the user's global color preference. A global color preference can be applied globally to all colors, while each memory color control can be applied only to the corresponding local color zone. Memory color processing can be applied on top of global color processing. For example, the gamut saturation can be increased by 10% (1.1 times the color saturation of each color in the gamut, including memory colors). Also, in this example, the local color region, such as the color saturation of red, may be 15% (1.15 multiplied by the color saturation of red). Therefore, the total color saturation adjustment for the red color is 1.1 x 1.15 = 1.265. To have a smooth transition from red to non-red colors, the 15% color saturation of red can be gradually reduced to 0% around the border between red and nearby colors. In the memory color adjustment depicted in FIG. 4, the selected memory color area can determine the color area for local contrast, saturation and hue adjustment. For example, if the "apple peel" region is selected, the internal algorithm will only apply the adjustment to the defined apple peel color region. If a "stem" area is selected, an internal algorithm can only apply the adjustment to the corresponding stem color area.

In some embodiments, once the user has instructed to accept the values of the display parameters controlled by the GUI 400, the device can capture and present different images of the same standard color through the GUI 400 to facilitate the customization of memorizing color preferences. Also, the customization process can be repeated a certain number of times (eg, a predetermined number of times) or until the user provides feedback via the GUI 400 that they are satisfied with the results. Once the display value of a particular standard color is finally determined, the device may repeat the above process for a different standard color in the set of standard colors available for the device. Once the display parameters are finally determined for each of the standard color sets, memory color preferences for each of the standard color sets are set for the user.

In some embodiments, for a given standard color, GUI 300 can automatically set initial values for display parameters based on feedback received for previous images. Also, the GUI 300 may allow the user to further adjust display parameters via one or more controls. In other embodiments, GUI 300 may sequentially receive feedback from the user (ie, via one or more controls) for different images, the feedback including values of display parameters for standard colors. In some embodiments, after storing the set of display values for a particular image, the initial values of the display parameters are reset to default positions for each new image of the same standard color. GUI 300 can display different images for repeated adjustments, and the adjustments can be accumulated. In the example of a hue adjustment, the default adjustment may be zero degrees. After displaying the red apple to adjust the red hue, the user can set an adjustment of +4 degrees. In response to the hue adjustment using hue addition, the adjusted hue angle may then be the input hue angle plus 4.
