Abstract
A dead pixel real-time detection method for image applicable in a digital camera is provided. The method is utilized to achieve the real-time detection of dead pixels in an image, upon obtaining the image by the digital camera, thus locating the dead pixel desired to be repaired. Through the real-time detection, the large amount of manpower and working-hours spent on detection and correction of the dead pixels of digital cameras on a production line can be saved, and the large amount of storage space occupied by the position information of the dead pixels in a digital camera can also be reduced. More importantly, in the detection process, the dead pixels can be determined more accurately through dynamically adjusting a threshold value as based on the different attributes of the various images, thus achieving the raising of the quality of the images significantly.
