[0052] 7 is a schematic flow chart of an imaging method according to an embodiment of the present application. As shown in FIG. 7, an embodiment of the present application further provides an imaging method applied to the camera module described in the above embodiment, and the imaging method may include the following steps 71 and 72:

[0053] In step 71, a first frame image is acquired by the camera module, and the driving component drives the image sensor to sequentially move a first predetermined distance in a first direction along a first straight line in a plane perpendicular to the optical axis of the lens, move a second predetermined distance in a second direction along a second straight line in a plane perpendicular to the optical axis of the lens, and move a third predetermined distance in a third direction along the first straight line in the plane perpendicular to the optical axis of the lens, thereby acquiring a second frame image, a third frame image, and a fourth frame image, wherein the third direction is opposite to the first direction.

[0054] 8 and 9, Fig. 8 is a schematic diagram of an RGB pixel array of an image sensor according to an embodiment of the present application, and Fig. 9 is a schematic diagram of an image capture by moving an image sensor provided by an embodiment of the present application. As shown in Fig. 8 and Fig. 9, taking the normal case where RGB pixels are arranged in a Bayer array arrangement as an example, in this step, first, a first frame of image is obtained by a camera module, then, a driving component of the camera module drives the image sensor to move a first predetermined distance in a first direction along a first straight line in a plane perpendicular to the optical axis of the lens, to obtain a second frame of image, and then, a driving component drives the image sensor to move a second predetermined distance in a second direction along a second straight line in a plane perpendicular to the optical axis of the lens, to obtain a third frame of image, and then, a driving component drives the image sensor to move a third predetermined distance in a third direction along the first straight line in a plane perpendicular to the optical axis of the lens, to obtain a fourth frame of image, where the third direction is opposite to the first direction.

[0055] In an embodiment of the present application, optionally, the first frame image includes several square pixel units, and the first predetermined distance, the second predetermined distance and the third predetermined distance are all positive integer multiples of a side length of a single pixel unit.

[0056] In step 72, a final image is generated based on the first frame image, the second frame image, the third frame image, and the fourth frame image.

[0057] By driving the pixel size displacement of the image sensor to obtain four frames of images, a final image can be generated based on the four frames of images. Optionally, the step of generating a final image based on the first frame of images, the second frame of images, the third frame of images, and the fourth frame of images can be acquiring single-channel data of each color in the first frame image, the second frame image, the third frame image, and the fourth frame image, respectively; rearrange single-channel data of the same color in the first frame image, the second frame image, the third frame image, and the fourth frame image to obtain several rearranged images; and fusing the reordered images to generate a final image.

[0058] For example, in the above step, R channel data, G channel data and B channel data in the first frame image, the second frame image, the third frame image and the fourth frame image are first obtained, and then the R channel data, G channel data and B channel data in the first frame image, the second frame image, the third frame image and the fourth frame image are rearranged to obtain several rearranged images. Here, it should be noted that since the arrangement form is a Bayer arrangement, two frames of rearranged images are obtained after the G channel data is rearranged. Finally, all the rearranged images are fused to obtain a final image.

[0059] FIG. 10 is a flow chart of processing a captured image in the prior art. As shown in FIG. 10, in normal shooting, when restoring an image, a mosaic removal algorithm (De-mosaic algorithm) is used to obtain one frame of R, G, B images by difference, and then fused to obtain a final image. The De-mosaic algorithm realizes the filling of signal information that is not acquired in a single channel by digital interpolation method (for example, the R channel is next to the G channel, and if the image sensor is not moved, the red R channel component information is missing at the position where the G channel is located), and it belongs to digital amplification, so the final imaging effect is not good. In the embodiment of the present application, the single channel data of each position is acquired by directly moving the image sensor, so that the resolution, dynamic range can be improved, noise can be reduced, and the fidelity of color reproduction can be improved, and thus the shooting effect can be improved.
