US 6,184,934 B2 · Video signal processing apparatus and composite image adjustment method

Abstract

A video signal processing apparatus inputting a plurality of video signals, making the plurality of video signals in parallel in order to display them as one image and setting peripheral parts of images which are adjacent to each other when they are placed in parallel as overlapped areas, and being able to execute a necessary correction processing about the video signals corresponding to the overlapped areas comprising: a remote controller being able to set the correction starting position and the correction end position, a correction data memory storing the correction data corresponding to the correction starting position and the correction end position set by the remote controller, and a control portion reading out the predetermined correction data from the correction data memory based on the correction starting position and the correction end position in a case where the correction starting position and the correction end position have been set.

Dependent claims

A video signal processing apparatus composing images formed from a plurality of input video signals in placing the images adjacent to each other, in order to display a composite image as an image, setting end parts of adjacent images as an overlapped area, and performing a correction process of a luminance level of the video signals corresponding to said overlapped area with correction data, comprising:

setting means for setting a correction starting position and a correction end position in said overlapped area,
correction data storage means for storing a plurality of correction data corresponding to said correction starting position and said correction end position, and
control means for controlling the read-out of the predetermined correction data from said correction data storage means based on the setting of said correction starting position and said correction end position.

A composite image projector apparatus including a video signal processing portion comprising:

a plurality of projector devices for projecting a composite image formed by composing images obtained from a plurality of video signals so as to place said images adjacent each other on a screen,
setting means for setting a correction starting position and a correction end position in an overlapped area in which end parts of adjacent images overlie each other,
correction data storage means for storing a plurality of correction data corresponding to said correction starting position and said correction end position,
control means for controlling read-out of predetermined correction data from said correction data storage means based on the setting of said correction starting position and said correction end position, and
correction processing means for correcting the luminance level of the video signal by said correction data.
