Abstract

Disclosed herein is a video signal processing device including, first and second input terminals, a size changer configured to change an image size of an image to be displayed based on a video signal input from the second input terminal, a mixer configured to mix a video signal input from the first input terminal with a video signal that has passed through the size changer, and an output terminal configured to output a video signal arising from mixing by the mixer.

Description

technical field [0001] The present invention relates to a video signal processing device and a display, and more particularly, to a video signal processing device that performs signal processing for displaying a plurality of pictures (multi-screen) on one display screen and a multi-screen using the video signal processing device monitor. Background technique [0002] In recent years, the size of display screens has become larger and larger. Furthermore, as the definition of displayed images becomes higher, the amount of information that can be displayed becomes larger. As one of displays having a particularly large screen, a so-called multi-screen (multi-window) display for displaying a plurality of screens (multi-screen) on one display screen is known (refer to, for example, Japanese Patent Laid-Open No. 2001-100718 ). [0003] FIG. 1 shows a basic configuration of a video signal processing device for realizing four multi-screens according to the prior art. This video s...
