    • The object is to provide a video signal processing apparatus capable of minimizing overtaking of fields of a video signal and continuous display of the video signal of the same field and reducing degradation in image quality of the output video signal. The apparatus has a field signal holding section 9 which holds the value of an input field signal and outputs the held value as a held value signal and a readout determination section 10 which determines the video signal of the field to be read out, and which outputs the determined signal as a readout field signal. The field signal holding section 9 holds the value of the input field signal a plurality of times with every occurrence of the readout field signal period, and outputs a held value signal constituted of the plurality of values of the input field signal held. The readout determination section 10 determines the video signal of the field to be read out from a frame memory 4 on the basis of the value of the held value signal in the current readout field period and the value of the held value signal in the immediately preceding readout field period.
    • 本发明的目的是提供一种视频信号处理装置,其能够最小化视频信号的场的超越和相同场的视频信号的连续显示,并降低输出视频信号的图像质量的劣化。 该装置具有保持输入场信号的值并输出保持值作为保持值信号的场信号保持部9和决定要读出的场的视频信号的读出判定部10, 所确定的信号作为读出场信号。 场信号保持部9在每次出现读出场信号周期时,多次保持输入场信号的值,并输出由保持的输入场信号的多个值构成的保持值信号。 读出判定部10基于当前读出场周期中的保持值信号的值和紧接着的前一个的保持值信号的值,确定从帧存储器4读出的场的视频信号 读出场周期。
