Title:
IMAGE PROCESSING APPARATUS, DISPLAY APPARATUS, AND IMAGE DISPLAYING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2008/015905
Kind Code:
A1
Abstract:
An image processing apparatus, a display apparatus and an image displaying system
wherein both secure and public images can be efficiently displayed with high
quality without lowering the contrast of the public images. There are included
a memory (101) that stores the image data of input secure and reversed images;
a data assigning circuit (102) that assigns a pulse train, which has the same pulse
width for the secure images and reversed images stored in the memory (101), as
an image signal consisting of a pulse train to be used for displaying images on
a display apparatus of PWM drive mode in which one frame is divided into a plurality
of subfields to express brightness gray scales; and a shutter spectacle control
signal generating circuit (103) that outputs a shutter control signal only during
outputting of image signals in accordance with the secure images. The secure
and reversed images have such a relationship that they become image data of images
having no correlation with the secure images when the brightness values of their
respective image data are added together for each pixel.
