Image processing method for optical image pointing device and optical video device

The invention relates to a processing method, and more particularly to an image processing method for an optical image pointing device and an optical video device, belonging to the technical field of image processing. According to the image processing method for the optical image pointing device and the optical video device, required exposure processing is performed on a photosensitive area of an image sensor, and at least two frames of image data are collected; the collected image data is processed so as to determine defective point types and defective point positions in the photosensitive area of the image sensor; and regular image data collection is performed in the photosensitive area of the image sensor, and the pixel average value of N pixel points around each determined defective point position is used to replace the pixel value of the defective point position. The method is convenient to operate, can realize effective processing of hardware errors of the image photosensitive area or bright spots and dark spots at the image fixed position due to pollution in the production process, has good adaptability, and is safe and reliable.
