摘要： A display device controls a signal applied to the n dots such that a sum of luminance of n dots (n is an integer of 1 or more) is virtually equal to an original luminance of the defective dot on the assumption that the n dots, which are adjacent to an electrically uncontrollable dot, are not originally illuminated. The display device also controls a signal applied to dots adjacent to the defective dot so as to display a color which is closer to an original color obtained by input signals to the defective dot and the adjacent dots.

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).
