IMAGE PROCESSING APPARATUS, METHOD, PROGRAM AND DISPLAY
First Claim
1. An image processing apparatus for creating two or more kinds of image signals using at least two kinds of input images and sequentially outputting the image signals therefrom:
- whereinone of the image signals is a first image signal which displays a first input image as one of the input images in a partial area of a screen;
all the image signals including the first image signal have a relationship to become, when a luminance value of each pixel thereof is totaled, a second input image which is one of the input images; and
the apparatus comprises an optical shutter control unit which controls, during a period in which at least the first image signal is being outputted, a shutter disposed between a display to which the image signals are inputted and user'"'"'s eyes to set the shutter to a light transmission state.

Abstract
This invention is to provide an image processing apparatus, an image processing method, a program, and a display in which both of a secret image and a public image can be efficiently displayed with high picture quality without reducing contrast of the public image. One of output images is a secret image which displays an input secret image as one of input images in a partial area of a screen, all the output images including the secret image have a relationship to become, when a luminance value of each pixel thereof is totaled, an input public image as one of the input images; and during a period in which at least the secret image is being outputted, shutter glasses disposed between a display to which the image signals are inputted and user'"'"'s eyes are set to a light transmission state.
