PROBLEM TO BE SOLVED: To provide an optical mechanism which executes finger recognition and finger navigation in combination utilizing a single sensing area having a sufficiently small size to be incorporated into an electronic device. SOLUTION: An image input system 10 can operate in finger navigation mode or finger recognition mode. A tip end of the finger 20 is abutted against a sensing area on a surface 115 comparted into two or more sections, and each of the two or more sections is irradiated by a plurality of light sources 120. A sensor 140 receives light 128 reflected on a part of the tip end of the finger 20 irradiated by one of the light sources 120 in the selected one section as a comparted image to generate image data 50 corresponding to the comparted image. An image processing system 200 processes the image data 50 in accordance with the selected operation mode of the image input system 10. COPYRIGHT: (C)2005,JPO&NCIPI

PROBLEM TO BE SOLVED: To provide a method for more efficiently performing de-mosaic processing of raw data image and size adjustment. SOLUTION: The method includes a step (302) for receiving an actual image block of a mosaic image, a step (308) for calculating the index of the actual image block according to color data of the actual image block, and a step (318) for generating an image block whose size is adjusted from the actual image block of the mosaic image in response to the index in order to prepare a size-adjusted image of the mosaic image. The generation of the size-adjusted image block includes a step for allocating color information which is selected from the actual image block of the mosaic image to the size-adjusted image block in such a way that the size-adjusted image of the mosaic image becomes a de-mosaic image.

Abstract:
PROBLEM TO BE SOLVED: To provide a mosaic reduction method of an image that reduces visibility in a zipper effect and can be mounted without the complication of hardware. SOLUTION: The adaptive mosaic reduction method for interpolating each pixel position is provided by separately considering degree of change (for example, other standards of gradient, Laplacian, or the degree of change) in both of horizontal and vertical directions on at least two color planes. Adaptive mosaic reduction algorithm uses a voting system to decide an interpolation direction at each pixel position. Each color plane votes for horizontality or verticality based on the comparison between vertical and horizontal constituents of the degree of change on the color plane. In one embodiment, the voting is counted according to measurement obtained by the pixel position itself and also from a close pixel. COPYRIGHT: (C)2003,JPO
