[0035] The real-time detection method of image dead pixel pixels proposed in the present invention is mainly applied to the image processing of digital cameras. For the step flow of the overall method, please refer to figure 2 The part is further explained as follows:
[0036] First, the external image must be obtained through the image sensing element of the digital camera (such as CCD or CMOS) (step 100). The pixels in the obtained image are basically arranged in an image matrix and temporarily stored in the digital camera. In the built-in storage media (such as flash memory), it is waiting for the subsequent real-time detection processing procedure of the image dead pixels.
[0037] At this time, the present invention sequentially selects the pixel to be tested and its surrounding adjacent pixel groups according to the arrangement order of the pixels in the image matrix to perform the dead pixel detection (step 110). It should be noted here that the present invention is based o...
