    • 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。

    • A video display device is provided with a video conversion circuit for extending an inputted video signal in horizontal and/or vertical directions, and a display unit including a display screen whose aspect ratio is longer in the horizontal direction than 16:9 and adapted to display the video extended by the video conversion circuit. The video conversion circuit includes a mode for extending the inputted video at a scaling factor of A, which is equal to or larger than 1, in the horizontal direction and at a scaling factor of B, which is equal to or larger than 1, in the vertical direction, so that videos effectively utilizing the aspect ratio of the video display device can be displayed while reducing incongruous feeling caused by the extension in the horizontal direction. Thus, an increase in the number of screen modes can be minimized, and modes capable of giving a remarkable sense of presence and modes capable of displaying right circles can be provided in the video display device with an aspect ratio of, e.g. 10:3.
    • 视频显示装置设置有用于在水平和/或垂直方向上延伸输入的视频信号的视频转换电路,以及包括在16:9的水平方向上的纵横比长于显示屏幕的显示屏幕的显示单元,并适于显示 该视频由视频转换电路扩展。 视频转换电路包括以水平方向等于或大于1的比例因子A以等于或大于1的比例因子B扩展输入视频的模式,等于或大于1, 垂直方向,从而可以显示有效利用视频显示装置的纵横比的视频,同时减少由水平方向延伸引起的不协调的感觉。 因此,可以使视频显示装置中的屏幕模式数量的增加最小化,并且能够提供显着的存在感和能够显示右圆的模式的模式可以具有例如宽高比的视频显示装置。 10:3。
