    • A video encoder for reducing the deterioration of picture quality of a compress coded video signal by implementing a method for deciding the number of picture elements needed to properly encode an inputted video signal. The decision is calculated based on the difficulty of compressing the inputted video signal and the number of picture elements needed to accurately reproduce a compressed inputted video signal. The decision circuitry decides the number of picture elements needed for compression of the inputted video signal allowing the number of codes generated in the encoding process to be decreased and quantization accuracy improved. The main advantage is a reduction in deterioration of the video signal usually found when reproducing a compress coded video signal.
    • 一种视频编码器,用于通过实现用于确定对输入的视频信号进行适当编码所需的像素数量的方法来减少压缩编码视频信号的图像质量的劣化。 基于压缩输入的视频信号的难度和精确地再现压缩的输入视频信号所需的像素的数量来计算该决定。 决定电路决定压缩输入视频信号所需的像素数量,从而允许降低编码处理中生成的代码数量,提高量化精度。 主要的优点是在再现压缩编码视频信号时通常发现的视频信号的劣化减少。

    • A solid-state imaging apparatus produces a sequentially-scanned video signal without using an expensive scanning converter. In the apparatus, an imaging device produces an image signal of each line based on the summation of signal charges of two adjacent lines. With the first mode being selected by the operation on the key panel, a timing generator is controlled to generate vertical shift pulses (field readout pattern) such that the two adjacent lines of the alternately-consecutive first and second fields are equal, causing the imaging device to produce an image signal for obtaining a sequentially-scanned video signal. An image signal processor implements the gamma modification process, etc. for the image signal to obtain the sequentially-scanned video signal. Sync signals VD and HD for sequential scanning or skip scanning generated by a sync signal generator are added to the video signal, and the output video signal is obtained.
    • 固态成像装置在不使用昂贵的扫描转换器的情况下产生顺序扫描的视频信号。 在该装置中,成像装置基于两条相邻线的信号电荷的总和产生每条线的图像信号。 在通过按键面板上的操作选择第一模式的情况下,控制定时发生器以产生垂直移位脉冲(场读出图案),使得交替连续的第一和第二场的两条相邻行相等,从而使成像 以产生用于获得顺序扫描的视频信号的图像信号。 图像信号处理器对图像信号执行伽马修正处理等,以获得顺序扫描的视频信号。 同步信号VD和HD用于顺序扫描或由同步信号发生器产生的跳跃扫描被加到视频信号中,并获得输出视频信号。
