摘要： PROBLEM TO BE SOLVED: To reduce the flickering half-tone on a display screen by providing an arithmetic device calculating the digital display data before being converted into frame control rate (FRC) display data.
SOLUTION: Display data are inputted to a liquid crystal display device 501 as digital display data 502 together with the dot clock 503, horizontal synchronization signal 504 and vertical synchronization signal 505 directly when the display data are digital data or after being converted into digital data by an A/D converting circuit when the display data are analog data. The RGB of the inputted digital display data 502 are independently inputted to an arithmetic value determining circuit 506 and an arithmetic circuit 508 respectively. The arithmetic circuit 508 makes arithmetic actions between the digital display data 502 and arithmetic values 507 generated for individual colors. An FRC converting circuit 510 converts digital display data 509 into FRC display data 511.

摘要： PROBLEM TO BE SOLVED: To provide an image processing technology for load-sharing and processing computing volume, when resolving an image to a higher resolution, including moving images, or the like.
SOLUTION: A first arithmetic device processes an even numbered image frames of an input image A as an object of high-resolution, and a second arithmetic device processes odd number-th image frames of the input image A as an object of high-resolution. As for the high-resolution processing, an input image B, which is the input image A delayed by a memory device 30 by one frame, is used as a reference image. Since the first arithmetic device and the second arithmetic device share computation processing, a properly high-resolved image can be generated, without producing missing of the frames of the output image, even if a processing time Tp becomes longer than a frame time Tf.
