摘要： An image signal processing circuit (102) includes a phase-expansion circuit (103), a digital polarity-inversion circuit (104), first to sixth D/A converters (111 to 116), and first to sixth operational amplifiers (151 to 156). The resistance value of the first to sixth amplitude adjusting resistors (121 to 126) which cause the output amplitude of an analog signal output from the first to sixth D/A converters (111 to 116) to be fixed is adjusted by laser trimming. First to sixth gain setting resistors (161 to 166) are connected to the first to sixth operational amplifiers (151 to 156). The first gain setting resistor (161) includes a first resistor (131) and a second resistor (141), and the gain of the operational amplifier (151) is set by the resistance ratio (R2/R1) thereof. In order that this resistance ratio (R2/R1) is fixed for each set, the first resistor (131) and the second resistor (141) are formed on the same substrate by undergoing the same manufacturing process. As a result, there is no need to use the first and second resistors (131, 141) for variable resistors.

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.
摘要翻译：本发明的一个方面提供了一种在显示部分上显示形成输入图像数据的多个输入像素的图像显示装置。在这种情况下，可以以与输入像素的灰度值不同的灰度值的显示像素组合的方式显示各输入像素。例如，当具有特定灰度值的像素存在作为输入像素时，像素保持在灰度值时不显示在显示部分上，而是以多个显示器的方式显示组合具有与输入像素的灰度值不同的灰度值的像素。结果，不会连续显示相同的灰度值。因此，这导致在TFD液晶面板中特别有问题的串音的发生被减少。因此，本发明可以通过控制显示图像的灰度级来消除TFD液晶面板中可能发生的串扰。

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.
