IMAGE PROCESSING APPARATUS, METHOD, PROGRAM AND DISPLAY

摘要

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.

主权项

1. An image processing apparatus for creating three image signals using two input images, including a secret image which only particular users can browse and a public image which unspecified persons can browse, and sequentially outputting the image signals therefrom, wherein:
an area in which a luminance value in the public image is equal to or more than a predetermined value is detected; a region, in which the secret image is displayed, is set in the area; the area is smaller in size than the public image, and the area is equal in size to the secret image; a first image signal, as one of the image signals, which displays the secret image in said region, is created; a second image signal, as one of the image signals, which displays the reverse image which an addition thereof to the secret image for each pixel is an image not having any correlation with the secret image in said region, is created; a third image signal, as one of the image signals, which displays the image obtained by subtracting the added result of luminance of the secret and reverse images from the luminance of the public image, is created; the first, second, and third image signals are sequentially output; 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.
