Image input device and image input method

A pattern producing unit performs arithmetic on values of pixels corresponding to a pattern and a basic pattern read from a data storing unit with an AND operation unit, and thereby produces a pattern having substantially the same shade level as the pattern. The latent-image-containing image producing unit produces the latent-image-containing image by selectively combining the pattern and the produced pattern according to the values of respective pixels of mask image data read from the data storing unit for producing a latent image.

Image forming apparatus and method forming a latent image for embedding information in an image

In an image processing method for reducing an input image while preventing moire without deterioration of image quality, presence/absence of periodicity is detected for each pixel on the input image, and if there is periodicity, an image period is detected (S). Sample points are sequentially extracted from the input image at prescribed sampling intervals (S). A value is obtained by multiplying the image period by n (n is a natural number) that exceeds the sampling interval, to set a smoothing area. Pixels around a sample point is smoothed in the set smoothing area. The pixel value for a reduced image is obtained (S). If there is an unprocessed sample point (NO at S), the step goes back to S, and the next sample point is subjected to a similar process. If the process is terminated for all the sample points (YES at S), the reduced image is output.

Image processing apparatus, image processing method, and medium on which image processing program is recorded

Reproduction means of a general-purpose computer () reproduces a digital content only when a device ID included in the digital content corresponds to a device ID of a device by which it is intended to reproduce the digital content. When the device ID of the general-purpose computer () is altered, a recovery program for recovering an original device ID is downloaded from a recovery program generation server (), thereby the device ID is recovered. With this arrangement, it is possible to provide a communication system which is capable of recovering a device ID when, for instance, the device ID is altered on account of the reinstall of a program such as an OS or content player.
