Latest Patents
One of Seki's latest patents is an image display and image displaying method for gradation correction. This innovative project involves detecting a luminance distribution in an effective video period of an inputted video luminance signal. A coefficient calculating circuit is utilized to calculate a correction coefficient C, which is essential for correcting gradation. The surrounding brightness is then detected, and the correction coefficient C is adjusted based on this brightness to obtain an adjusted correction coefficient C'. This adjustment allows for a luminance to be raised according to a brightness signal, even for pixels with the lowest input luminance. Another notable patent is a noise reduction method and apparatus designed to reduce mosquito noise while retaining edges. This apparatus calculates the maximum value Y of the difference values of adjacent pixels in a specified area and controls a pixel replacement device based on this value.
