    Abstract: PROBLEM TO BE SOLVED: To provide an adaptive quantization signaling for maintaining the adaptability to an available decoding system. SOLUTION: Previously-unused slots in a Huffman code table associated with a JPEG image file are associated with various quantization matrices (Q matrices) that are used to quantize data blocks of the JPEG image file. Huffman codes associated with the various Q matrices permit the particular Q matrix used to quantize a given data block to be signaled by a decoder as an end-of- block (EOB) code. The EOB codes and the Huffman code table are sent with the JPEG image file. Upon decoding of the image file, a standard JPEG decoder reads each of the EOB codes as a standard JPEG EOB code and does not vary the Q matrix. COPYRIGHT: (C)2003,JPO

    Abstract: 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 method and system for shaping a spatial response of a spatial filter. SOLUTION: A method and system for shaping a spatial response of a spatial filter are provided. The spatial filter includes a number of photodetectors that generate individual signals in a time domain. The individual signals are subsequently divided and grouped to create I and Q channels outputted from the spatial filter. Prior to the formation of the I and Q channels, a window function is used to shape the spatial response of the spatial filter. COPYRIGHT: (C)2006,JPO&NCIPI

    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

    Abstract: PROBLEM TO BE SOLVED: To provide an image sensing device for detecting/correcting a bad pixel where memory requirements of buffers are minimized. SOLUTION: A sensor includes an array of photodetectors each generating an output signal of pixel data indicative of incident light intensity. The pixel data are read out from the array one line at a time and stored in a line buffer (116). A bad pixel processor (110) includes a first buffer (104) that stores pixel data obtained from the line buffer (116) for a certain pixel in a currently read out line and pixel signal light data for pixels adjacent to the certain pixel (108). An included second buffer (122) stores features (124) that are indicative of whether the pixels in a previously read out line were identified as bad pixels. Using the information in the first and second buffers, the processor identifies whether the certain pixel is a bad pixel.
