Latest Patents

Nishitani’s latest patents address image quality and video reliability.

“Image Processing Device and Image Capturing Device That Perform Demosaic Process” describes a method for determining a pixel’s color difference. The device detects edge information using the brightness of the pixel and nearby pixels, calculates both an average and a median of their color differences, and selects between those values based on the edge information.

“Video Processing Device and Display System” describes a way to detect frozen video. The device embeds a changing frame number in blocks of video data as they are written to memory. It then reads the blocks and generates an abnormality signal if the frame number remains unchanged for a specified number of consecutive checks.
