Patent ID: 7660432

Claim:
An authentication image creation device comprising: memory means that, for each of a plurality of pixels making up an original image, stores pixel data indicating a display color of each pixel; update pixel obtaining means that obtains pixel data of at least two pixels of the original image that have been selected according to a positional relationship between the at least two pixels and a target pixel in a specific location of the original image, wherein the at least two pixels and the target pixel are present in the original image; update data specifying means that specifies update data for the target pixel based on the pixel data of the at least two pixels obtained by the pixel obtaining means, for an image processing device to subsequently compare the update data against pixel data of a pixel of a target original image, the pixel of the target original image being located in the target original image at a position corresponding to the specific location of the target pixel in the original image, so as to determine, based on the comparison, before creating a stereoscopic image, whether or not to allow stereoscopic processing for creating the stereoscopic image; and data processing means that alters the pixel data of the target pixel stored on the memory means based on the update data specified by the update data specifying means.
