Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 アスペクト比3:4の画像を2画面表示する 場合は、画質の劣化が少なく、アスペクト比9:16の 画像を上下伸長表示する場合は、走査線間隔が粗くなる ことがないアスペクト比9:16の表示部を有するテレ ビジョン受像機を提供する。 【構成】 2画面変換部2はアスペクト比3:4の画像 信号である入力1,2を水平方向は1/2に、垂直方向 は2/3に圧縮し、メモリ部4に書き込む。走査線変換 部3は入力1をメモリ部4に書き込み、読み出した信号 を走査線変換することにより走査線を4/3倍に増大さ せる。切換回路5は表示切換信号によって2画面変換部 2及び走査線変換部3により変換された信号を切り換え て9:16表示部1に出力する。 (57) [Abstract] [Purpose] When displaying an image with an aspect ratio of 3: 4 on two screens, there is little deterioration in image quality, and when displaying an image with an aspect ratio of 9:16 in a vertically expanded state, the scanning line spacing is rough. Provided is a television receiver having a display unit with an aspect ratio of 9:16 that does not occur. [Structure] The two-screen conversion unit 2 compresses inputs 1 and 2 which are image signals having an aspect ratio of 3: 4 into ½ in the horizontal direction and ⅔ in the vertical direction, and writes them in the memory unit 4. The scanning line conversion unit 3 writes the input 1 in the memory unit 4 and converts the read signal into scanning lines to increase the scanning lines by 4/3. The switching circuit 5 switches the signals converted by the two-screen conversion unit 2 and the scanning line conversion unit 3 according to the display switching signal and outputs the signals to the 9:16 display unit 1.
