摘要： Aspects of the invention can provide an image processing circuit for gray scale correction, an image display apparatus, and an image processing method that allow reduction in the storage capacity needed for storing correction characteristics data without increasing clock rate in relation to interpolation processing of correction characteristics. A exemplary image processing circuit according to the invention can be applied, for example, to color correction or gamma correction of color image data. Gray scale correction characteristics data for a number of gray scale levels that is less than the number of gray scale levels of input image data can be stored in first and second lookup table storing units. Considering a gray scale value of a pixel that is being considered for gray scale correction processing as an input gray scale value, the first and second lookup-table storing units are referred to, obtaining an output gray scale value corresponding to the input gray scale value and an output gray scale value corresponding to an adjacent input gray scale value. An adjacent gray scale value refers to a gray scale value that is higher by one or lower by one than another input gray scale value. Then, output gray scale values between these two adjacent output gray scale values can be calculated by linear interpolation, obtaining output values for all input gray scale values. Subsequently, gray scale correction can be performed for each pixel of input image data, outputting corrected image data.

摘要： Aspects of the invention provide an image-display apparatus including an image display, such as a liquid-crystal display panel, where the image display can display a limited number of gray scales, interpolation is performed so that the number of gray scales displayed by the image display becomes the same as that of gray scales of obtained image data. The image-display apparatus can have the liquid-crystal display panel or the like and can be mounted on a mobile phone, a PDA, and so forth, so as to process and display image data transmitted from outside sources. First, a CPU performs a bit-slice process for the obtained image data, so as to reduce the data amount thereof. Next, a dither processing unit performs a dither process for interpolating the reduced data amount, so as to represent half-tone gray scales simulatively. In the invention, the dither process can be performed by using a 3×3 dither matrix for data whose gray-scale value corresponds to a predetermined area and a 2×2 dither matrix for data whose gray-scale value does not correspond to the predetermined area. Subsequently, the image display can display a predetermined image, where the number of gray scales of the predetermined image is the same as that of gray scales of the obtained data.

摘要： An aspect of the invention provides an image display apparatus that displays a plurality of input pixels which form input image data on a display section. In that case, each input pixel can be displayed in such a manner that display pixels having gradation values differing from the gradation value of the input pixel are combined. For example, when a pixel having a particular gradation value exists as an input pixel, the pixel is not displayed on the display section as it is being kept at the gradation value, but instead, is displayed in such a manner that a plurality of display pixels having gradation values differing from the gradation value of the input pixel are combined. As a result, the same gradation value is not displayed continuously. Therefore, this results in that the occurrence of crosstalk, which is problematical particularly in a TFD liquid-crystal panel, is reduced. Accordingly, the invention can remove crosstalk which is likely to occur in a TFD liquid-crystal panel by controlling the gradation level of a display image.

摘要： The present invention: (1) divides a selection period into a plurality of sub-selection periods (t11, t21, t31, t41), and distributes these sub-selection periods throughout the period in one frame; (2) further divides a sub-selection period into a plurality of divided sub-selection periods ((s1, s2), (s3, s4), (s5, s6), (s7, s8)), and switches electric potentials of the selection signals between divided sub-selection period in order to eliminate the effects of spikes in voltage from the scanning signals to be applied to adjacent scanning electrodes, and applies these features to commonly known multi-line driving method. The present invention is capable of: (1) controlling unevenness of display in the direction of signal electrodes (normally vertical direction), (2) not causing especially severe uneven display in the direction of signal electrodes and flickering even when the display contents change one after another, and (3) preventing the occurrence of an uneven display in the direction of scanning electrodes (normally horizontal direction).

摘要： Method and apparatuses for compensating for perceived blur due to inter-frame motion in a sequence of digital video frames are disclosed. One example method includes blurring a current frame using first and second blurring filters to generate first and second blurred frames, respectively. A first weighted combination of the current frame, the first blurred frame, and the second blurred frame is then blurred with the first blurring filter to generate a third blurred frame. The current frame is combined with the third blurred frame in a second weighted combination to generate a blur-compensated frame.
