Current lenses generally use digital zoom to obtain images at all focal lengths. However, digital zoom is achieved by enlarging the image, which will reduce the resolution of the image and cannot guarantee that the resolution of the image at the full focal range remains unchanged.

The main camera 10 is used to obtain a main original image of a first pixel size, the telephoto camera 20 is used to obtain a telephoto original image of a second pixel size, and the camera module 100 finally outputs a target image of a third pixel size. Both the first pixel size and the second pixel size are larger than the third pixel size. For example, it can be: the first pixel size is greater than the second pixel size, and the second pixel size is greater than the third pixel size; or, the first pixel size is equal to the second pixel size, and the first pixel size (second pixel size) is greater than the third pixel Size; or, the first pixel size is smaller than the second pixel size, and the first pixel size is larger than the third pixel size. The embodiments of the present application are described by taking an example that the first pixel size is equal to the second pixel size, and the first pixel size (the second pixel size) is greater than the third pixel size. In one embodiment, the first pixel size may be 48 million pixels, the second pixel size may be 48 million pixels, and the third pixel size may be 12 million pixels.

The main camera 10 can be a normal camera (the field of view is between the field of view of the telephoto camera and the field of view of the wide-angle camera), or a wide-angle camera. The main camera 10 can be a fixed focus lens or a zoom lens . The telephoto camera 20 is a zoom lens, and the telephoto camera 20 can include a first telephoto state and a second telephoto state.

The embodiment of this application takes the first predetermined zoom factor of 3 times and the second predetermined zoom factor of 5 times as an example for description, that is, the camera module 100 can work in a zoom mode less than 3 times, greater than or equal to 3 times and less than 5 times. A zoom mode that is 5 times or more, and a zoom mode that is greater than or equal to 5 times.

It can be understood that in other examples, the first predetermined zoom factor may not be 3 times, and the second predetermined zoom factor may not be 5 times. The first predetermined zoom magnification can be set to other magnifications such as 2 times, 4 times, or 5 times. At this time, the zoom magnification corresponding to the first long focal length state of the telephoto camera 20 also corresponds to other magnifications such as 2 times, 4 times, or 5 times. The second predetermined zoom factor can be set to other magnifications such as 3 times, 4 times, or 6 times. At this time, the zoom factor corresponding to the second long focal length state of the telephoto camera 20 also corresponds to other magnifications such as 3 times, 4 times, or 6 times. For example, when the first predetermined zoom factor is set to 2 times, the zoom factor corresponding to the first telephoto state of the telephoto camera 20 is also corresponding to 2 times, and the second predetermined zoom factor can be set to 3 times. The zoom factor corresponding to the second long focal length state also corresponds to 3 times; when the first predetermined zoom factor is set to 4 times, the zoom factor corresponding to the first long focal length state of the telephoto camera 20 also corresponds to 4 times, and the second predetermined zoom factor The zoom factor can be set to 6 times, and the zoom factor corresponding to the second long focal length state of the telephoto camera 20 also corresponds to 6 times; when the first predetermined zoom factor is set to 5 times, the first long focal length state of the telephoto camera 20 The corresponding zoom factor also corresponds to 5 times, the second predetermined zoom factor can be set to 6 times, and the zoom factor corresponding to the second long focal length state of the telephoto camera 20 also corresponds to 6 times.

Take, for example, that the entire zoom range of the zoom mode of the camera module 100 is 0 to 10 times. The camera module 100 can zoom in the (0, 3) zoom multiple range, and the main original image is obtained by the main camera 10 in this interval, thereby obtaining the target image. The camera module 100 can also perform zooming in the [3, 5) zoom multiple range, in which the telephoto camera 20 acquires the telephoto original image in the first telephoto state to obtain the target image. The camera module 100 can also perform zooming in the [5, 10] zoom multiple range, in which the telephoto camera 20 acquires the telephoto original image in the second telephoto state to obtain the target image. The zoom method of the embodiment of the present application can ensure that the resolution of the target image in the full focal range (0, 10) is unchanged, and the imaging performance is improved.

Wherein, the process of obtaining the target image from the main original image or the telephoto original image may include a process of performing image processing on the main original image or the telephoto original image, such as first image processing and/or second image processing. By performing the first image processing and/or the second image processing on the main original image or the telephoto original image, a target image of 12 million pixels can be obtained from the main original image of 48 million pixels or the original telephoto image of 48 million pixels. The first image processing may be compression processing, and the second image processing may be cropping processing. Of course, in other embodiments, the process of obtaining the target image from the main original image or the telephoto original image may also include not only the first image processing and/or the second image processing, but also more methods of image processing. This is not limited.

Referring to FIG. 4, in one embodiment, the compression process may include an averaging operation. Specifically, each frame of the main original image and each frame of the telephoto original image (hereinafter collectively referred to as the original image) includes a plurality of pixels distributed in two dimensions, for example, 4*4 pixels. The pixel values of multiple pixels from left to right and top to bottom are: 135, 132, 120, 105, 160, 140, 112, 110, 153, 89, 87, 62, 105, 87, 53, 45. A predetermined number of pixels in multiple pixels can be used as a group (for example, 4 pixels circled by a dashed frame as a group), by compressing the pixel values of 4 pixels in each group, a merged target image is finally obtained The pixel value of the pixel. For example, the pixel values of the 4 pixels in the upper left corner are averaged, (135+132+160+140)/4=133, and the pixel value of the combined pixel in the upper left corner of the target image is 133. By analogy, the pixel values of the 4 pixels in the upper right corner are averaged, and the pixel value of the combined pixel in the upper right corner of the target image is 112; the pixel values of the 4 pixels in the lower left corner are averaged to get the target The pixel value of the merged pixel in the lower left corner of the image is 109; the pixel value of the 4 pixels in the lower right corner is averaged, and the pixel value of the merged pixel in the lower right corner of the target image is 62, which will not be expanded here. Description. Finally, a combined pixel with a pixel value of 133, a combined pixel with a pixel value of 112, a combined pixel with a pixel value of 109, and a combined pixel with a pixel value of 62 form a target image.

It should be pointed out that in the actual processing process, the processor 200 needs to average the 48 million pixels in the original image to obtain a target image of 12 million pixels. The number of pixels to be processed far exceeds the 4*4 in the above example. Pixels.

In this embodiment, the pixel values of the target image obtained by compression processing are directly derived from the original image, and no pixels are added, so the resolution of the target image obtained by compressing the original image will not decrease.

Referring to FIG. 5, in another embodiment, the compression process may include a maximum value operation. Still taking the aforementioned 4*4 pixel original image as an example, by compressing the pixel values of 4 pixels in each group, the pixel value of a combined pixel in the target image is finally obtained. For example, the maximum value operation is performed on the pixel values of the 4 pixels in the upper left corner, MAX(135,132,160,140)=160, and the pixel value of the combined pixel in the upper left corner of the target image is 160. By analogy, the maximum value of the 4 pixels in the upper right corner is calculated, and the pixel value of the combined pixel in the upper right corner of the target image is 120; the maximum value of the 4 pixels in the lower left corner is calculated, The pixel value of the combined pixel in the lower left corner of the target image is 153; the maximum value of the four pixels in the lower right corner is calculated, and the pixel value of the combined pixel in the lower right corner of the target image is 87. Expand the description one by one. Finally, a combined pixel with a pixel value of 160, a combined pixel with a pixel value of 120, a combined pixel with a pixel value of 153, and a combined pixel with a pixel value of 87 form a target image.

It should be pointed out that in the actual processing process, the processor 200 needs to perform a maximum operation on the 48 million pixels in the original image to obtain a target image of 12 million pixels. The number of pixels to be processed far exceeds the 4*4 in the above example. Of pixels.

In this embodiment, the pixel values of the target image obtained by compression processing are all derived from the original image (the pixel values are all the original values in the original image), and no pixels are added, so the target image obtained by compressing the original image The resolution will not decrease.

Referring to FIG. 6, in one embodiment, the cropping process may include cutting out a pixel area with the same aspect ratio as the original image from the original image, and using this pixel area as the target image, and discarding the pixels outside the pixel area. For example, when it is desired to obtain a target image of 12 million pixels from an original image of 48 million pixels, the number of pixels of the image captured by the cropping process is one-fourth of the number of pixels of the original image, so the length and width are the same as those of the original image. One-half, the field of view of the target image is one-half of the original image, and the visual effect is a 2x zoom visual effect.

In this embodiment, the pixel values of the target image obtained by cropping are all derived from the original image (the pixel values are all the original values in the original image), and no pixels are added, so the target image obtained by cropping the original image The resolution will not decrease.

Referring to FIG. 7, in some embodiments, when the camera module 100 is in a zoom mode less than the first predetermined zoom factor, the main camera 10 is controlled to obtain the main original image, and the target image (that is, 01) is obtained according to the main original image. ,include:

012: When the camera module 100 is in the zoom mode of the second zoom factor, control the main camera 10 to obtain the main original image, and perform the second image processing on the main original image to obtain the target image; and

013: When the camera module 100 is in the zoom mode between the first zoom factor and the second zoom factor, control the main camera 10 to obtain the main original image, and perform the first image processing and the second image processing on the main original image to obtain the target image;

Wherein, the first zoom factor and the second zoom factor are both smaller than the first predetermined zoom factor.

Referring to FIG. 2, in some embodiments, the camera module 100 can be used to execute the methods in 011, 012, and 013.

In other words, when the camera module 100 is in the zoom mode of the first zoom factor, the main camera 10 can obtain the main original image, and the camera module 100 can perform the first image processing on the main original image to obtain the target image; When the group 100 is in the zoom mode of the second zoom factor, the main camera 10 can obtain the main original image, and the camera module 100 can perform the second image processing on the main original image to obtain the target image; when the camera module 100 is at the first zoom factor and In the zoom mode between the second zoom factor, the main camera 10 can obtain the main original image, and the camera module 100 can perform the first image processing and the second image processing on the main original image to obtain the target image; wherein, the first zoom factor and The second zoom multiples are all less than the first predetermined zoom multiples.

The embodiment of the present application is described by taking an example in which the first zoom factor is 1 time and the second zoom factor is 2 times. The fixed focal length of the main camera 10 may be the focal length corresponding to the first zoom factor.

Referring to Figure 8, when the camera module 100 is in the 1x zoom mode, the processor 200 controls the main camera 10 to obtain a main original image of 48 million pixels, and compresses the main original image of 48 million pixels to obtain 12 million pixels. The target image. Specifically, the compression process may be the aforementioned mean value operation or maximum value operation. In the embodiment of the present application, by performing compression processing on the main original image of 48 million pixels, the electronic device 1000 can output a target image of 12 million pixels with a constant field of view.

Referring to Fig. 9, when the camera module 100 is in the 2x zoom mode, the processor 200 controls the main camera 10 to obtain a main original image of 48 million pixels, and performs cropping processing on the main original image of 48 million pixels to obtain 12 million pixels. The target image. Since the field of view corresponding to the 2x zoom mode is generally smaller than the field of view corresponding to the 1x zoom mode, the implementation of this application needs to crop the main original image of 48 million pixels to reduce the field of view. This allows the electronic device 1000 to output a target image of 12 million pixels with a reduced field of view and a constant resolution compared to the 1x zoom mode. The area intercepted by the cropping process may be the middle area of the main original image, or may be an area determined according to user input.

Referring to FIG. 10, when the camera module 100 is in a zoom mode between 1x and 2x (for example, a 1.5x zoom mode), the processor 200 controls the main camera 10 to obtain a main original image of 48 million pixels, and compares the 4800 The main original image of megapixels is cropped and compressed to obtain a target image of 12 million pixels. Specifically, the processor 200 may first perform cropping processing on the main original image of 48 million pixels to obtain an intermediate image, and then perform compression processing on the intermediate image to obtain a target image of 12 million pixels. The pixel size of the intermediate image is smaller than the pixel size of the main original image and larger than the pixel size of the target image. For example, the pixel size of the intermediate image may be 21 million pixels. The processor 200 first performs cropping processing on the main original image of 48 million pixels to obtain an intermediate image of 21 million pixels. The area intercepted by the cropping processing may be the middle area of the main original image, or an area determined according to user input. Then, the processor 200 performs compression processing on the 21 million pixel intermediate image to obtain a 12 million pixel target image, and the compression processing may be the aforementioned mean value operation or maximum value operation. Since the field of view corresponding to the 1.5x zoom mode is generally smaller than the field of view corresponding to the 1x zoom mode, the embodiment of the present application needs to perform cropping processing on the main original image of 48 million pixels to obtain an intermediate image of 21 million pixels. In order to reduce the field of view, the 21 million pixel intermediate image is compressed to make the electronic device 1000 output a 12 million pixel target image with a reduced field of view and unchanged resolution compared to the 1x zoom mode. .

In addition, referring to FIG. 11, when the camera module 100 is in a zoom mode between 2x and 3x (for example, a 2.4x zoom mode), the processor 200 controls the main camera 10 to obtain a main original image of 48 million pixels, and The main original image of 48 million pixels is cropped and enlarged to obtain a target image of 12 million pixels. The processor 200 may specifically first perform cropping processing on the main original image of 48 million pixels to obtain an intermediate image, and then perform enlargement processing on the intermediate image to obtain a target image of 12 million pixels. The pixel size of the intermediate image may be smaller than the pixel size of the main original image and smaller than the pixel size of the target image. For example, the pixel size of the intermediate image may be 8 million pixels. The processor 200 first performs cropping processing on the main original image of 48 million pixels to obtain an intermediate image of 8 million pixels. The area intercepted by the cropping processing may be the middle area of the main original image, or an area determined according to user input. Then, the processor 200 performs a magnification process on the 8-megapixel intermediate image to obtain a 12-megapixel target image, and the magnification process may be to directly enlarge the image by zooming. It can be understood that the 12-megapixel target image is obtained by enlarging the 8-megapixel intermediate image, and the image resolution is slightly reduced, which can almost be regarded as unchanged. Since the field of view corresponding to the 2.4x zoom mode is generally smaller than the field of view corresponding to the 1x zoom mode, the implementation of this application needs to perform cropping processing on the main original image of 48 million pixels to obtain an intermediate image of 8 million pixels. In order to reduce the field of view, the 8 million pixel intermediate image is enlarged to make the electronic device 1000 output compared to the 1x zoom mode, the field of view is reduced, and the resolution is almost unchanged. image.
