摘要： In cases where the amount of gradation transition is greater than a threshold value, a modulation processing section corrects image data D of a current frame by making an interpolation calculation with reference to a look-up table, and output the image data D thus corrected. In cases where the amount of gradation transition is not more than the threshold value, the modulation processing section directly outputs the image data D of the current frame. Furthermore, in one embodiment of the present invention, the look-up table contains, as output image data D2 corresponding to a case where the image data D of the current frame is identical to image data D0 of a previous frame, a value which is neither of the image data D of the current frame and the image data D0 of the previous frame and by which output image data D2 corresponding to the inputted image data D and D0 of the previous and current frames is calculated according to the interpolation calculation in cases where the amount of gradation transition is greater than the threshold value. With this, an image display apparatus is realized which can be balanced between a reduction in circuit size and an improvement in display quality at a higher level.

摘要： A display has a circuit for comparing video data for a first or current frame with video data for a second or desired frame. A processing section makes an instruction for a process to take place if certain conditions are met. In response to the instruction for a process, a signal generation circuit outputs a signal which reduces a degree of modulation or variation by which tone transition is facilitated relatively to a case where pixels are driven on the basis of data output from an ordinary processing section. Thus, by modulating or varying a drive signal to a degree suitable for a case where tone transition is sufficient, a display capable of improving display quality even in a situation where the display is not capable of being driven suitably, can be realized using circuitry of a relatively small scale.

摘要： In a method for driving a display, a display, and a program therefor, a memory stores uncorrected video data for a desired frame and for a current frame until a next frame. Meanwhile, a correction section reads uncorrected video data for the previous frame and the current frame from the memory and corrects the video data for the current frame. Further, a processing section corrects video data for the next frame based on the corrected video data for current frame so as to facilitate a grayscale level transition from the current frame to the next frame.

摘要： A liquid crystal display apparatus includes an applied gradation value acquiring section for receiving gradation data of a frame to be displayed, gradation data of a frame to be outputted, gradation data of the current frame supplied from a frame memory and measured data from a temperature sensor. An interpolation operation is then carried out in reference to look-up tables stored in a look-up table memory so as to calculate a target applied gradation data required for gradation display. The section sets for each LUT (a) a coordinate system in which a lattice point is represented by a combination of the gradation data of the current frame and the gradation data of the target frame and (b) a local coordinate system having lattice points corresponding to the target gradation data in the coordinate system; carries out interpolation operation by use of the local coordinate system, and carries out further interpolation operation based on the interpolated value (table interpolated value), in accordance with the measured data so as to calculate the target applied gradation data. The adoption of the interpolation by use of the local coordinate system enables the finding of the target applied gradation data (interpolated value) with higher accuracy, while a variety of additional conditions are taken into consideration.

摘要： A liquid crystal display apparatus includes a plurality of areas in which response speeds greatly different from each other coexist in a pixel. A first replacement process section replaces the image data of the desired target frame with a first gradation, when a gradation transition from a current frame to a desired target frame corresponds to the above gradation transition. A second replacement process section replaces the image data of the current frame with a second value. The first value is set to a value causing the pixel to respond at a relatively higher speed without the occurrence of the excessive brightness. Without avoiding the deterioration of the image, it is possible to drive a liquid crystal display apparatus including areas whose response speeds are different from each other coexist in the pixel, such as a liquid crystal display apparatus of vertically aligned mode and normally black mode.

摘要： In one embodiment of the present invention, to time-divide one frame of an input image signal into a first-half sub frame and a second-half sub frame, the grayscale of the signal in the second-half sub frame is set at a grayscale for dark display and the grayscale of the display signal of the first-half sub frame is adjusted, when the input image signal indicates low brightness. When an image with high brightness is displayed, the grayscale of the display signal of the first-half sub frame is set at a second predetermined value smaller than the maximum value and the grayscale of the display signal of the second-half sub frame is adjusted. Thereafter, in accordance with a combination of the input image signals of the (N-1)-th frame and the N-th frame, overshoot is performed with respect to the display signal of the first-half sub frame.
