A recently filed patent (Publication Number: US20240031696A1) outlines a method for correcting image data captured by a photosensor array. The method involves receiving image data associated with an image, determining the location of a target pixel with a defect, identifying operating pixels in overlapping regions, calculating a simulated pixel value based on a weighted average of these pixels, and assigning this value to the target pixel in the image data. The process is executed by a processor and can be applied using a kernel. The simulated pixel value is determined by calculating sums of pixel values for operating pixels in different regions and is further refined based on counts of these pixels.
Furthermore, the patent describes a system for correcting image data, comprising an imager, a display, and an image processor. The processor receives image data, identifies the target pixel location, calculates simulated pixel values based on weighted averages of operating pixels in different regions, and displays the corrected image data on the display. The system also includes mechanisms for detecting pixel faults in the photosensor array based on the image data, ensuring accurate correction. Overall, the patent details a comprehensive method and system for effectively correcting image data captured by a photosensor array, enhancing the quality of images presented on displays.
