摘要： A clock ride-over circuit in which clock ride-over may be achieved even if jitter is contained in clocks prior to and subsequent to ride-over and no control input signal for write and readout is applied from outside. A clock prior to rideover CLK—1 is detected by a clock subsequent to ride-over CLK—2 which is of a higher speed than the clock prior to ride-over. A timing signal TIM of a constant period, generated by a counter adapted for self-running with the clock prior to ride-over, is compared to the phase comparison signal COMP which is the result of the clock detection. Stable clock ride-over is possible by the phase comparison signal COMP having a pulse width larger than the jitter period of the clock subsequent to ride-over.

摘要： The present invention relates to an image processing system for afterimage reduction for suitable use in a stereoscopic television apparatus. This system has been devised in consideration of the fact that the afterimage in a TV camera image to be displayed is most influenced by a frame image previous to the image to be displayed. The afterimage can be reduced by performing a novel algorism operation on each pixel value. Pixel values of a right image stored in a second input frame memory, which has been output from the TV camera prior to a left image to be displayed which is supplied from an input selector, is multiplied by a predetermined coefficient. The multiplied value is subtracted from pixel values of the left image to be displayed. Thus, a left image to be displayed, which has been subjected to afterimage reduction processing, is produced, and stored in a first output frame memory. Similarly, a right image to be displayed, which has been subjected to afterimage reduction processing, is produced.
摘要翻译：本发明涉及一种用于立体电视设备中适用的余像减少的图像处理系统。考虑到要显示的电视摄像机图像中的残像受到要显示的图像之前的帧图像的影响最大的事实，已经设计了该系统。可以通过对每个像素值执行新颖的算法操作来减少残像。将从输入选择器提供的要显示的左图像之前从TV摄像机输出的第二输入帧存储器中存储的右图像的像素值乘以预定系数。从要显示的左图像的像素值中减去相乘值。因此，产生已经进行了余像减少处理的待显示的左图像，并将其存储在第一输出帧存储器中。类似地，产生已经进行了余像减少处理的要显示的右图像。
