Detailed ways

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

Embodiment one

Referring to FIG. 1 , it shows a flow chart of steps of an image capturing method according to Embodiment 1 of the present invention.

The image capturing method of the embodiment of the present invention includes the following steps:

Step 101: Detect the shooting button detection area.

The image capture method in the embodiment of the present invention is applied to a mobile terminal, the screen of the mobile terminal is a touch screen, and when the image capture interface is opened, a capture button is displayed in the image capture interface.

The shooting button detection area is the area facing the shooting button. This area may be a cylindrical area facing the shooting button. The cross section of the cylindrical area is the same shape and size as the shooting button. Of course, the region may also include the cylindrical region and have a larger volume than the cylindrical region; the region may also be included in the cylindrical region.

The mobile terminal detects the shooting button area in real time, the purpose is to detect whether there is a finger in the shooting button detection area, not only that, but also detect the distance between the finger and the shooting button after the finger appears in the shooting button detection area.

Step 102: When it is detected that the finger is located in the shooting button detection area and the distance between the finger and the shooting button is greater than or equal to a preset value, take at least one first image.

When detecting the distance between the finger and the shooting button, the ultrasonic wave integrated in the mobile terminal screen or the Home button in the mobile terminal can be used to identify the distance between the finger and the screen, which is the distance between the finger and the shooting button.

It should be noted that, in a specific implementation process, the preset value may be set by those skilled in the art according to actual needs, which is not specifically limited in this embodiment of the present invention. Under the time interval from when the finger is away from the preset value of the shooting button to when the shooting button is clicked, the object to be photographed is just clearly imaged in the captured image. The preset value is inversely proportional to the imaging speed of the mobile terminal, and the faster the imaging speed is, the smaller the preset value is.

Step 103: taking a second image when it is detected that the finger touches the shooting button.

The operation of the finger touching the shooting button can be detected by the pressure sensor installed under the shooting button. Specifically, the pressure sensor detects the pressure value of the shooting button, and the central processing unit obtains the pressure value detected by the pressure sensor, and judges according to the pressure value Whether the capture button receives finger touch. Certainly, it is also possible not to detect the pressure value through the pressure sensor, but to directly detect the operation of the finger touching the shooting button by the touch of the mobile terminal.

Step 104: Determine whether the mobile terminal shakes when taking the second image; if yes, perform step 105, and if not, perform a setting operation.

When judging whether the mobile terminal shakes when taking the second image, it can be judged whether the clarity of the second image is greater than a preset value, and if so, it is determined that the mobile terminal shakes when taking the second image; otherwise, it is determined that the mobile terminal is taking pictures. There is no judder in the second image.

Wherein, the setting operation may be set to use the second image as the target image; or may be set to prompt the user to take the image again.

If the mobile terminal shakes when taking the second image, it will affect the clarity of the taken second image, so the second image taken when the mobile terminal shakes cannot be used as the target image. Select the image with the highest resolution from one image as the target image.

Step 105: If shaking occurs, use the image with the highest definition among the first captured images as the target image.

At least one first image has been captured through steps 102 to 103. In the embodiment of the present invention, in order to recommend the first image with the best shooting effect to the user, an image processing algorithm is used to select the highest-definition image from all the captured images. The image is recommended to the user as the target image, so that the user can obtain the optimal captured image.

In the image capturing method provided by the embodiment of the present invention, when it is judged that the user wants to capture an image, the image is captured when the finger does not touch the capture button. Since the finger does not touch the capture button, the mobile terminal will not shake, so clear images can be captured. high-resolution images. When the operation of the finger touching the shooting button is detected, take a second image and determine whether the mobile terminal shakes when taking the second image, and if the shake occurs, select the image with the highest resolution in the first image as the target shot image . In this way, even if the mobile terminal shakes during the shooting of the second image and affects the clarity of the second image, the clearest image can be selected from the first captured image as the target image, so it can effectively avoid the mobile terminal shaking. Therefore, the problem of low resolution of the captured image is caused, thereby improving the user experience.

Embodiment two

Wherein, the shooting button detection area is a cylindrical area facing the shooting button. As shown in FIG. 3 , area A is the shooting button detection area, B is the screen of the mobile terminal, C is the shooting button on the screen, D is the finger, and Y is the preset value.

The mobile terminal detects the shooting button detection area in real time, and the purpose is to detect the distance between the finger and the shooting button after the finger appears in the shooting button detection area.

Step 202: When it is detected that the finger is located in the shooting button detection area and the distance between the finger and the shooting button is equal to a preset value, take a first image.

The preset value is the minimum imaging distance between the shooting button and the finger on the screen. Under the time interval from when the finger is away from the shooting button preset value to when the shooting button is clicked, the object to be photographed is just clearly imaged in the captured image. The preset value is inversely proportional to the imaging speed of the mobile terminal, and the faster the imaging speed is, the smaller the preset value is.

When the distance between the finger and the shooting button is equal to the preset value, the image shooting function is turned on, and the image shooting can ensure that a clear image can be captured before the finger touches the shooting button.

At present, the imaging speed of mobile terminals is very fast, so the preset value Y is very small. Basically, the time point when the camera is triggered is close to the time point when the user touches the shooting button, and the user basically has no perception.

Step 203: taking a second image when an operation of touching the shooting button with a finger is detected.

The operation of the finger touching the shooting button can be detected by the pressure sensor installed under the shooting button. Specifically, the pressure sensor detects the pressure value of the shooting button, and the central processing unit obtains the pressure value detected by the pressure sensor, and judges according to the pressure value Whether the capture button receives finger touch.

Step 204: Determine whether the mobile terminal shakes when taking the second image; if yes, execute step 206; if not, execute step 205.

Step 205: If there is no shaking, take the second image as the target image.

Step 206: If shaking occurs, take the first image as the target image.

In the embodiment of the present invention, because the second image is taken when the mobile terminal shakes, the clarity of the second image will definitely be affected, and the first image is taken before the finger does not touch the shooting button. The mobile terminal will not shake when the first image is captured by touching the shooting button, so the definition of the first image is higher than that of the second image. Therefore, the first image is directly recommended to the user as the target image, so that the user can obtain the optimal captured image.

Step 207: Display all captured images, and highlight the target image.

In the specific implementation process, the target image can be directly recommended to the user, and a user image selection button is provided. By triggering the image selection button, the user can trigger the mobile terminal to display all the captured images, and the user can select images from all the captured images. choose. It is also possible to directly display all images, and highlight the target image to prompt the user that the target image is the highest-definition image captured for the user to select.

The image capturing method provided by the embodiment of the present invention, in addition to the beneficial effects of the image capturing method shown in the first embodiment, can also display all the captured images to the user for the user to choose, which can satisfy the user's personalization demand and improve user experience.
