Description

  The present invention relates to an image processing apparatus that captures, records, and reproduces still images and moving images.

Electronic cameras and direct printers, which are called direct prints and can be directly connected to a printer without using a PC or other device, are already on the market. By using these electronic cameras and direct printers, anyone can easily and easily print captured images without requiring complicated operations. A small direct printer driven by a battery is also commercially available. For example, an image taken outdoors can be printed immediately on the spot.
JP 2003-280848 A

  In general, an image taken by an electronic camera can be displayed on a display device such as a liquid crystal panel built in the camera. When the photographed image is printed using a direct printer, it is generally displayed on a liquid crystal panel and the composition, exposure, focus, hue, etc. are confirmed in advance. The composition can be confirmed by displaying an image on the liquid crystal panel. In addition, with a camera having a function of displaying a histogram and a whiteout warning together with an image, exposure can be confirmed. Further, if the camera has an enlarged display function, the focus can be confirmed in detail.

  However, the liquid crystal panel display of an electronic camera has a difference in color, brightness, contrast, etc. between different models and individual differences, so even the same shot image may be displayed differently. . In addition, the electronic camera is used under various light sources, indoors and outdoors, regardless of the surrounding environment in which it is used. Therefore, the influence of the light source is large, and a difference in the appearance of the liquid crystal panel may occur.

  On the other hand, when printing a captured image using a PC, it is generally used indoors, the surrounding environment is constant, and the change in the light source is small. In addition, there is a display that can be adjusted in detail, and the display screen and the print result can be matched. Also, printing is often performed after changing to a color or the like that the user feels preferable by retouching or the like.

  For the above reasons, when performing direct printing with an electronic camera, it is difficult to determine the printing result from the liquid crystal panel display, and a printing result that satisfies the user is obtained compared to printing using a PC. It is thought that it is hard to be done. In addition, even if the display on the liquid crystal panel matches the print result, the electronic camera generally does not have a function such as retouching. Cannot be changed.

  The present invention has been made paying attention to the above-mentioned problems, and print results that the user feels preferable without being affected by the difference between the electronic camera and the model of the direct printer to be connected and individual differences. An object is to provide an image processing apparatus that can be obtained.

  In order to solve the above problems, the present invention comprises the following arrangement.

  In an image processing apparatus capable of printing captured still images and / or moving images by directly connecting to a printing means, a first print mode for printing with settings unique to the image processing apparatus, and a print result that the user feels preferable Printing having a second print mode for finding the image and a third print mode for obtaining a print result that the user feels favorable, and satisfying the user in the first print mode If the result cannot be obtained, a predetermined parameter is determined based on the print result obtained in the second print mode, and the print result that the user feels preferable is reflected in the third print mode. It can be obtained.

  Some conventional electronic cameras have a function called a WB (White Balance) bracket. By using the function of the WB bracket, it is possible to record a plurality of photographed images in which white balance conditions are changed by one photographing. However, even if this method is used, there is no confirmation that a photographed image that the user feels favorable can be obtained, and a plurality of pieces of photographed data are recorded by one photographing. If it is, it is not an effective means. There are also cameras that have a function that allows the user to change the degree of color tone, sharpness, etc., called development parameters, but as described in the section on issues, print results are judged from the LCD screen. Difficult to do.

  By using the present invention, it is possible to obtain a print result that the user feels preferable without being affected by the difference between the electronic camera and the type of the direct printer to be connected, or the individual difference.

  When the playback switch 66 is operated, the captured image is displayed on the image display unit 28 (S202). The image display sequence will be described with reference to FIG.

  The image processing apparatus 100 reads the captured image data recorded on the recording medium 200 or the recording medium 210 (S302) and transfers it to the memory 30 (S304). The captured image data transferred to the memory 30 is decompressed by the image compression / decompression circuit 32 (S306) and expanded again in the memory 30 (S308). The image data developed in the memory 30 is resized to a size that can be displayed by the image display unit 28 (S310) and stored in the image display memory 24 (S312).

It is possible to qualitatively determine the degree of change in the color tone of the image. Note that the data displayed on the image display unit is generated from the captured image using an arbitrary conversion formula using a parameter selected by a user's operation.

  After determining the parameters by the user, a plurality of images are displayed in an index form on the image display unit 28 as shown in FIG. In the present embodiment, the photographed image (P510), the image (P520) generated from the photographed image by the conversion formula using the parameter determined by the user, and a value smaller by one step than the parameter determined by the user are used. There are four types of images: an image (P530) generated from the captured image by the conversion formula (P530), and an image (P540) generated from the captured image by the conversion formula using a value one step larger than the parameter determined by the user. indicate. Thereby, it is easy to determine how much the color tone has changed due to the parameter change with respect to the original photographed image.

  In the second printing mode, the four types of images are printed in the same index form as the display screen, and images that the user feels preferable are selected from the printing results. As described above, a parameter corresponding to the selected image, that is, an optimum parameter can be obtained. By printing an image in the vicinity of the parameter selected by the user as in P530 and P540, it becomes easier to obtain a print result that the user feels preferable.

  A sequence when the first or third printing mode is selected instead of the second printing mode in S210 (S222) will be described with reference to FIG. First, general settings relating to printing are performed. In this embodiment, image trimming is set first (S602). The image trimming setting determines which range of the image is to be printed. If the camera has an enlargement display function, the trimming range can be selected while being enlarged. Of course, it is possible to make the entire image as a whole. Next, the print style is set (S604). In the setting of the print style, it is possible to set the presence or absence of a border and the presence or absence of date printing. In addition, the paper size is set (S606), the number of printed sheets is set (S608), and the like. The paper size can be selected from sizes that can be printed by the printer. Finally, parameters determined by the second print mode are set (S610). From the result of the second print mode, it is possible to input parameters that the user feels preferable. If the parameters are left at the default values, the settings are specific to the camera (that is, the first print mode is set).

  An image reflecting the parameters is displayed on the image display unit 28 (S224). Data is transferred to the connected direct printer 400 (S226). As described above, a print result reflecting the parameters determined by the second print mode, that is, a print result requested by the user can be obtained (S228).
