摘要： A multiple primary color display device (100) includes a plurality of pixels (P) located in a matrix including a plurality of rows and a plurality of columns. The plurality of pixels are each formed of a plurality of sub pixels including at least four sub pixel for displaying different primary colors from one another. The multiple primary color display device can sort the plurality of sub pixels which form each of the pixels into n number of virtual pixels (n is an integer of 2 or greater), each of which is formed of two or more sub pixels, and use each of the n number of virtual pixels as a minimum color display unit for providing display. The two or more sub pixels which form each of the n number of virtual pixels include a sub pixel common to another of the n number of virtual pixels. When a line having a width corresponding to the n number of virtual pixels is displayed, two sub pixels which are located at both of two ends, in a width direction, of the line and which display a certain identical primary color to each other have a luminance lower than the luminance that the two sub pixels originally have.

摘要： A display device according to the present invention includes a plurality of pixels arranged in a matrix. Each of the plurality of pixels is formed of four or five types of sub pixels that display different colors from each other. In each pixel, a first sub pixel that displays a color having the highest luminance and a second sub pixel that displays a color having the second highest luminance are located so as not to be adjacent to each other. The four or five types of sub pixels include a plurality of display units, each of which is capable of displaying a specific color and is formed of one sub pixel or two or more continuous sub pixels.

The video image transmitting device (1) includes an editing device (2) for superimposing first and second video signals on each other according to video combining information, a video image encoding processing portion (3) and a video image composite information encoding processing portion (4) for encoding the output video signal from the editing device (2) and video combining information respectively, a multiplexing processing portion (5) for multiplexing the encoded data, and a transmitting portion (6) for transmitting the multiplexed data. The video image receiving device (11) includes a receiving portion (12) for receiving the multiplexed data, a multiplexed data separating processing portion (13) for separating the multiplexed data into the video data and the video image decoding processing portion (14) and a video image composite information decoding processing portion (15) for decoding the video data and the video combining information respectively, and a video image signal processing portion (16) for subjecting the decoded video signal to a predetermined video signal processing. The video image signal processing portion (16) adequately controls the video signal processing of the portion of the second video signal superimposed on the first video signal by using the video combining information, thereby prevents image degradation of and around the portion of the second video signal caused by the video signal processing, and generates a video with higher quality.

摘要： The liquid crystal display device inputs a signal, corrected by a correction circuit provided with a sigmoid inverse function generator, to a source driver. A sigmoid function which is an S-shaped function is used to approximate an input/output characteristic (applied voltage-transmittance curve) of a liquid crystal panel. The sigmoid inverse function generator converts an input signal by using an inverse function of the sigmoid function obtained by performing the approximation. A γ conversion circuit provided on the correction circuit and the sigmoid inverse function generator realize the desired γ characteristic regardless of a characteristic of the liquid crystal panel. Further, since the inverse function of the sigmoid function which is an S-shaped function is used, it is possible to provide a display device which corrects the input/output characteristic of the display panel by performing the approximation in accordance with not plural functions but a single function (without dividing the characteristic into sections).
