IMAGE PROCESSING DEVICE AND METHOD, PROGRAM, AND DISPLAY DEVICE

摘要

Provided are an image processing device, which does not detect any flicker even when a secret image is browsed through a shutter eyeglass, a method for the device, a program and a display device. The image processing device comprises a code-generating/data-assigning circuit (102) for setting the sequence, in which a secret image and a reversed image are displayed, on the basis of an orthogonal code, and a shutter eyeglass control signal generating circuit (103) for making controls to make the shutter eyeglass, as arranged between the post display device and the eyes of a user, into an optically transparent state while the image signal of an image containing at least a portion or the entirety of the secrete image is being outputted, and to make the shutter eyeglass into a shielding state while another image is being displayed. The image signal of the secret image and the image signal of the reversed image are in such relations that they form an image having no correlation to the secret image when the brightness values of the individual images are added for every pixels.
