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.

摘要： The invention provides an easy and simple method of converting the resolution of image data, which is capable of generating the high-resolution image data without incongruity, does not make a circuit in the display device complicated and does not increase the power consumption. This invention can include a portable terminal device, such as a mobile telephone or a PDA, that processes and displays image data transmitted from the outside. Image data with a plurality of grayscales can be displayed by controlling the display state of each pixel in a display unit in accordance with grayscale control pulses corresponding to the number of grayscales. For example, when a 64 grayscale display is performed, a grayscale level is defined using sixty four grayscale control pulses. Thus, it is possible to emit light from pixels in the display unit by sixty four grayscale levels. Further, the resolution converting device can generate pseudo-high-resolution image data obtained by increasing the number of pixels of original image data by n multiplication and by reducing the number of grayscales of the original image data to 1/n. When displaying the pseudo-high-resolution image data, the number of grayscale control pulses is changed to 1/n by a halftone controller. That is, in the pseudo-high-resolution image data, the number of grayscales is 1/n. Therefore, the number of grayscale control pulses used for halftone display may be 1/n in accordance with the number of grayscales. Therefore, the low-resolution image data can be displayed without incongruity by converting the resolution, also, it is possible to reduce power consumption of the display unit by the reduced amount of the number of grayscale levels pulses.
摘要翻译：本发明提供了一种简单且简单的转换图像数据的分辨率的方法，其能够不引起高分辨率图像数据的产生，而不会使显示装置中的电路复杂化，并且不增加功耗。本发明可以包括处理和显示从外部发送的图像数据的诸如移动电话或PDA的便携式终端设备。可以通过根据与灰度数对应的灰度级控制脉冲控制显示单元中的每个像素的显示状态来显示具有多个灰度的图像数据。例如，当执行64灰阶显示时，使用六十六个灰度级控制脉冲来定义灰度级。因此，可以从显示单元中的像素发射六十六个灰度级的光。此外，分辨率转换装置可以生成通过相乘乘以原始图像数据的像素数量并将原始图像数据的灰度数减少到1 / n而获得的伪高分辨率图像数据。当显示伪高分辨率图像数据时，通过半色调控制器将灰度级控制脉冲的数量改变为1 / n。也就是说，在伪高分辨率图像数据中，灰度数为1 / n。因此，用于半色调显示的灰度控制脉冲的数量可以是根据灰度数的1 / n。因此，可以通过转换分辨率来显示低分辨率图像数据而不一致，还可以通过减少灰度级别脉冲数量来减少显示单元的功耗。
