摘要： A method and apparatus for a TV receiver in which a frame of TV image signals is stored in the image memory and then read out for display as a still picture. In order to display both still picture and subsequent motion pictures, the image signals sampled with the number of pixels corresponding to the number of addresses in a specified area of the image memory are written in the process of reading out all the addresses of the image memory.

摘要： When an input component image signal is inputted in a signal processing step, a high-frequency signal emphasis processing like HPF is performed with respect to a luminance signal and a processing like LPF with replenishment of the low-midrange frequency signal is performed in an LPF step and a color signal step with respect to color difference signals. Then, the luminance signal and color difference signals are outputted by prescribed clock pulses. The clock pulse of the color difference signals may be set lower than the clock pulse of the luminance signal according to the condition of the image. Processed as above, a new component image signal (a luminance signal Y and any combination of color difference signals U and V, V and W, W and U) is generated from a conventional component image signal (Y and U, V, W) without loss in image information or image quality. Furthermore, the amount of data of the signal to be generated per unit of time is reduced as compared with the conventional component coding system of 4:1:1 or 4:2:0 (MPEG). Thus, a signal processing method and device which enables signal transmission with lower transmission rate can be achieved.
摘要翻译：当在信号处理步骤中输入输入分量图像信号时，相对于亮度信号执行像HPF这样的高频信号强调处理，并且在LPF中进行处理，在LPF中执行补充低中频信号步进和色差信号步进。然后，通过规定的时钟脉冲输出亮度信号和色差信号。可以根据图像的条件将色差信号的时钟脉冲设置为低于亮度信号的时钟脉冲。如上所述，从传统的分量图像信号（Y和U，V，W）产生新的分量图像信号（亮度信号Y和色差信号U和V，V和W，W和U的任何组合）不损失图像信息或图像质量。此外，与传统的4：1：1或4：2：0（MPEG）组件编码系统相比，每单位时间产生的信号的数据量会减少。因此，可以实现能够实现具有较低传输速率的信号传输的信号处理方法和装置。
