摘要： A colour display system (3) is disclosed that is capable of taking input (e.g. NTSC) intended to be displayed on a full colour display (e.g. VDU) having a high refresh rate and displaying the image on a display (e.g. FLCD) having a much reduced number of displayable colours and a lower refresh rate. 24-bit RGB data is input (19) and converted into bi-level RGBW data and halftoned in a render unit (16) for storage (6) before display. Motion detection (15) is used to ensure that only those pixels that have change in value are updated on the display.

摘要： Display standards in common use for the display of computer or television images on high resolution displays, commonly assume that the output image will be displayed on an output device having a high refresh rate. A high refresh rate is normally required to avoid the viewer observing flicker, stilted motion or other visual artifacts if a lower refresh rate were used. It is difficult to drive some displays (5) at a high refresh rate. Apparatus (16) is disclosed for detecting areas (33,36) of an input image (2,24) that are changing over time, even where the input image may be subject to some degree of noise. A priority value is determined for providing a measure of this change for use with a system to determine which areas of the image may need changing as a matter of high priority.

摘要翻译：公开了一种彩色显示系统（3），其能够接收旨在显示在具有高刷新率的全色显示器（例如，VDU）上的输入（例如NTSC），并且在具有一个或多个显示器的显示器（例如FLCD）上显示该图像可显示颜色数量大大减少，刷新率较低。 24位RGB数据被输入（19）并转换成双电平RGBW数据，并且在显示之前在渲染单元（16）中半色调存储（6）。运动检测（15）用于确保在显示器上仅更新具有值变化的像素。
