20100097405 | COLOR GAMUT MAPPING METHOD FOR MULTIMEDIA EQUIPMENT, A TELEVISION AND A COLOR PROCESSING APPARATUS - A color gamut mapping method for multimedia equipment is disclosed. This method performs color gamut mapping on a video signal received by the multimedia equipment and gives an output, wherein the video signal is in a first color color gamut while display light of the multimedia equipment is in a second color gamut. The color gamut mapping method for multimedia equipment comprises the steps of: converting the received video signal into a luminance signal and a chrominance signal, and calculating a two-dimensional plane according to the luminance signal and the chrominance signal, wherein the two-dimensional plane intersects the first color gamut to obtain a first region and intersects the second color gamut to obtain a second region; calculating location of a to-be-mapped point corresponding to the video signal in the first region according to the luminance signal and the chrominance signal of the video signal, and calculating a mapping point in the second region by making calculations on the to-be-mapped point to output a mapping point signal. | 04-22-2010 |
20090207318 | Control unit, a video device including said control unit, and a control method - The present invention discloses a control unit, a video device employing said control unit and a control method thereof, wherein the control unit includes: a recognition device which is used to recognize the target in the target image; a calculation device which is used to calculate and transform the position coordinate of the recognized imaging target from the recognition device and output the position of the operation unit. | 08-20-2009 |
20090115718 | LIQUID CRYSTAL DISPLAY METHOD AND THE APPRATUS THEREOF - The present invention discloses a liquid crystal display method, which can adjust the brightness of different segments of backlight according to the different images. Especially, the present invention discloses a liquid crystal display method, which includes: receiving a image signal; analyzing the image signal; dividing the image into at least two image segments according to the analysis result of the image signal; dividing the backlight into at least two backlight segments according to the division result of the image; adjusting the brightness of the backlight in each backlight segment; adjusting the image signal in each image segment. The liquid crystal display method of the present invention divide the image and the backlight according to the image signal, while adjusting the brightness of the image and backlight in each segment to not only decrease the power consumption of the liquid crystal display, but also increase the contrast of the image signal, thereby improving the effect of liquid crystal display. | 05-07-2009 |
