Description

Image acquisition method and device

technical field

The present invention relates to the field of image capturing, in particular to an image acquisition method and device.

Background technique

In the related art, the objective resolution of the camera needs to be tested for the objective test of the camera. It is necessary to adjust the terminal lens and the test chart (ISOresolution Chart for Electronics Still Cameras) under the condition that the test sample is turned on and the camera is set to the maximum resolution. The distance between them makes the image of the card clear, and the thick frame in the horizontal direction is parallel to the horizontal frame of the screen. The shooting is to make the effective height of the card (the height inside the thick frame) just cover the screen. Generally, the ratio of horizontal pixels to vertical pixels in the image format is 4:3, so that the captured picture can be within the black line.

In related technologies, there are generally two ratios of image size (pixels) captured and stored by the camera, 4:3 resolution or 16:9 resolution, and the highest pixel aspect ratio of the mobile phone is also selected according to one of the two resolutions. The size of the mobile phone screen is VGA, QVGA, WVGA, etc., and the aspect ratio is usually 4:3, 3:2, 16:10, 15:9, 16:9, etc.; When the size ratio of the mobile phone screen conforms to 4:3 or 16:9, the photo taken corresponds to a resolution picture of 4:3 or 16:9, then, you can realize what you took and what you get, so that the horizontal direction The thick frame of the screen is parallel to the horizontal frame of the screen. The shooting is to make the effective height of the picture card (the height inside the thick frame) just cover the screen, so as to ensure the correctness of the resolution test. When the screen size ratio of the mobile phone does not meet 4:3 or In the case of 16:9 requirements, there is a difference between the preview and the captured photo when taking pictures in full-screen mode, which leads to the failure of the test resolution framing and cannot be detected.

And then when the camera in the related art takes pictures, in order to show what is taken and what is obtained, a mandatory preview size conversion is carried out on the preview interface, and the photo of 4:3 pixels is taken, and the preview picture is exactly 4:3, 16:9 pixels The photo is taken, and the preview picture is 16:9. When the mobile phone screen is not in these two ratios, the upper and lower sides of the mobile phone preview interface will not display images, and what is presented to the user is a black border.

Aiming at the problem in the related art that when the screen size ratio of the mobile phone is inconsistent with the resolution of the camera of the mobile phone, no image will be displayed on the upper and lower sides of the preview interface of the mobile phone, and there is no effective solution yet.

Below in conjunction with optional embodiments of the present invention are illustrated;

In this optional embodiment, by judging the screen size ratio and resolution of the mobile phone, in the full-screen preview state, according to the set shooting picture size ratio, an imaging preview box prompt is generated to ensure that the picture in the preview box is the image range of the actually generated photo .

Fig. 6 is a schematic diagram of the relationship between the full-screen preview photographing results and the actual preview interface according to an optional embodiment of the present invention. As shown in Fig. 6, when the screen size of the mobile phone is the same as the size ratio of the photo, there is no such thing as what you see is not what you get. The ratio of digital photos is currently 4:3 and 16:9, while the screen size ratio of mobile phones has a variety of 4:3, 3:2, 16:10, 15:9 and 16:9, any two Combination, full screen mode preview will appear what you see is not what you get.

Fig. 7 is a flow chart of a method for framing and photographing at a specific ratio according to an optional embodiment of the present invention. As shown in Fig. 7, the steps of the method include:

Step S701: collecting hardware information of the mobile phone, wherein the hardware information includes: LCD hardware resolution and LCD hardware size information of the mobile phone;

Step S702: Obtain the pixel ratio of the LCD;

Step S703: setting the camera resolution;

Step S704: collect the resolution set by the camera of the mobile phone, wherein the resolution of the camera can be 4:3 or 16:9;

Step S705, judging whether the resolution of the LCD is consistent with the resolution of the camera; if the judging result is no, execute step S706;

Step S706: full screen preview;

Step S707: Generate a preview box prompt and take a photo.

Through the above steps S701 to S707, it can be seen that it is necessary to read the resolution and size information of the LCD screen in the mobile phone from the mobile phone hardware configuration information table, determine whether the screen has the characteristics of 4:3 or 16:9, and record the information of the mobile phone at the same time proportional features. Then read the photo resolution information and preview status information set last time from the camera setting module in the mobile phone, mainly judge whether it is a full-screen preview or a non-full-screen preview, calculate the ratio relationship of the photo resolution set by the mobile phone camera, and judge that it is 4 :3 or 16:9 relationship and save.

When the resolution and photo size ratio set on the camera are different from the screen resolution ratio of the mobile phone, and the preview interface of the mobile phone is in the full-screen preview state, the mobile phone generates a prompt viewfinder frame consistent with the photo size ratio, which is convenient for the user to find a view and ensures that the viewfinder is consistent with the photo. The photos turned out to be consistent. Fig. 8 is a schematic diagram showing the effect of a preview prompt box according to an optional embodiment of the present invention. As shown in Figure 8, the inside of the dotted line frame means that after taking a photo, it can be saved on the photo, and outside the dotted line frame, although it can be seen on the preview interface, the taken photo cannot be saved on the photo.

According to the effect and size of the generated preview frame, when the user actually takes a photo, the actual viewfinder range data needs to be passed to the entry function of the image storage operation to ensure that the range of the prompt box in the user preview interface is consistent with the actual saved photo range data are consistent.

The embodiment of the invention also provides a storage medium. Optionally, in this embodiment, the above-mentioned storage medium may be configured to store program codes for performing the following steps:

S1: Before previewing the image acquired by the terminal camera in full screen, acquire the first resolution of the terminal display screen and the second resolution of the terminal camera;
