Latest Patents

One of his latest patents is an image display device and method designed to address issues such as high power consumption, insufficient contrast, image flicker, and distortion in image display devices. This innovative device includes an image display management module with a backlight control unit. The backlight control unit features an image brightness analyzer that generates a brightness value based on input image data, a weight generator that produces a weight according to the brightness value, an image variation analyzer that assesses the input image data to generate an image variance, and a backlight factor generator that creates a backlight adjusting signal based on the weight and image variance. This technology allows the image display device to achieve power-saving and contrast enhancement effects.

Another significant patent by Chen-Jung Tsai is a method of displaying a low dynamic range image in a high dynamic range. This method increases the dynamic range of an image composed of multiple pixels, each with a luminance value within a first luminance dynamic range. The process involves determining a background luminance value for each pixel, identifying the minimum and maximum of these values, and calculating a conversion factor for each pixel. The image is then converted from the first luminance dynamic range to a second by multiplying each pixel's luminance value by its conversion factor.
