Abstract
The present invention provides a method for preventing sensor array from generating fixed dark band pattern after long-time exposure, which sequentially includes the step of increasing virtual cells for increasing the exposure time, the step of obtaining picture data, and the step of data configuration. The step of increasing virtual cells is to increase the number of virtual cells in the sensor array. The step of obtaining picture data is to obtain a physical address with physical image signal, virtual image signal, corresponding physical image signal, and the picture data corresponding to the virtual address of the virtual image signal. Finally, the step of data configuration can arrange the physical image signal on the physical area of a picture, and arrange the virtual image signal on the virtual area of the picture. Thus, the method can prevent generating the pattern with fixed dark band in the picture, and further improve the quality of the image.
