Abstract: Methods of generating a secured printed document on paper or other medium by printing a security layer made of a transparent conductive material over the ink/toner layer that forms the visible content of the document. The security layer is printed using a transparent conductive material such as transparent conductive toner or ink and is invisible to human eyes. In one embodiment, the transparent conductive material contains a pattern that forms a radio frequency (RF) transponder circuit which has an RF antenna and a digital memory storing security data, which can be read out and used to authenticate the document. In another embodiment, the pattern forms a memory circuit without an RF antenna. In yet another embodiment, the transparent conductive material is patterned but does not form a functional circuit, and the electrical properties of the security layer such conductivity and/or capacitance are used to authenticate the document.

Abstract: Provided are a portable input device for inputting coordinates, a method of calibrating the device, and a computer readable recording medium storing a computer program for making a computer perform the method. The portable input device includes two digital cameras, a calibration tool, a storage section, and a controller for calculating coordinates of an object on an input surface based on images taken by the two digital cameras based on images taken by the two digital cameras so as to include the calibration tool. The controller also calibrates positions and widths of a detection band which corresponds to a detection zone defined in a vicinity of the input surface. The positions and the widths of the detection band are stored in the storage section in relationship to positions on the input surface.

Abstract: The present application relates to a digital photo album producing apparatus which can produce the digital photo album file so that a player for a removable optical storage medium can decode and display the digital photo album file, and the index file so that the index file comprises still thumbnail image data and pointer which is a command to jump to a certain chapter or segment of digital photo album file including still image or movie corresponding to the thumbnail image.

Abstract: The present application relates to a digital photo album producing apparatus which can produce the digital photo album file so that reproducing of the image starts with the reproducing of the background music without complicated process for synchronizing the reproducing of the background music and the images.

Abstract: The present application relates to a digital photo album producing apparatus which can produce the digital photo album file so that reproducing of the image and the reproducing of the background music ends at the same time.

Abstract: The present application relates to a digital photo album producing apparatus which can produce the digital photo album file so that when the digital photo album is reproduced, both of the background music and audio of movie can be reproduced at good balance.

Abstract: The present application relates to a method and apparatus to convert various photographs from a photographic album to digital form.

Abstract: The present application relates to an apparatus for making postcards to allow a user to print postcards with images from, e.g., a digital camera.

Abstract: There is described a system and a method for transferring digital image data for archiving and for ordering photographic prints through the network between a photofinisher and a customer.

Abstract: A controller for use with an image formation device. An image formation system includes an image formation device and a controller associated with the image formation device. The image formation device can be operated in either copier mode or printer mode. In printer mode, the controller receives print jobs and forwards the print jobs to the image formation device. The controller converts the print jobs to pixel data and stores the pixel data in memory to buffer the print jobs. The controller also interprets print commands and controls functions performed by the image formation device.
