Latest Patents

Among his latest patents, Itoman has developed an image processing device and a liquid crystal display device. The image processing device generates a second output image signal for a second liquid crystal panel, which is superposed on a first liquid crystal panel. This device includes a first corrector that generates a gamma correction signal to adjust the gradation value of an input image signal. It also features a detector that identifies image regions brighter than their surroundings, allowing for improved image quality. The second corrector then modifies the gamma correction signal to decrease the gradation value of the identified high-frequency portions, resulting in a refined output image signal.

The liquid crystal display device consists of first and second liquid crystal panels that overlap each other. It incorporates a parallax reduction unit that generates the second output image signal through smoothing processing based on the input image signal. Additionally, a first temporal filter creates a response correction signal that determines the first output image signal, ensuring a seamless viewing experience.
