Abstract: An image processing method and device, a camera apparatus and a storage medium are provided. The image processing method includes: acquiring an initial image, and the initial image corresponds to an RGB data format; dividing the initial image into a plurality of image blocks; converting each image block in the plurality of image blocks from the RGB data format into a YUV data format, wherein Y is a luminance value, and U and V are chromatic value; inverting a luminance value Y of a target image block into a darkness value D, and the target image block is at least one of the plurality of image blocks; coding DUV data of the target image block and YUV data of a non-inverted image block so as to obtain target image data of the initial image.
