摘要： A data buffer receives and temporarily stores data including a product code enabling error correction in first and second directions. An exclusive-OR operation circuit uses an error amount detected by error correction in the first direction and data stored in a storage element to calculate a first error check result. A PI direction error-checking circuit according to the first error check result performs error check after error correction in the first direction. A PO direction partial error-checking circuit and a PO direction aggregate error-checking circuit use an error amount detected in error correction in the second direction and calculate a second error check result. The first and second error check results are used to generate a final error check result by an exclusive-OR operation circuit.

摘要： In a verification apparatus, an image pickup unit picks up an image of an object to be verified. A calculation unit calculates, from the captured object image, a characteristic quantity that characterizes a direction of lines within the object image along a first direction or a characteristic quantity that characterizes the object image as a single physical quantity. Then a region from which data are to be acquired is set by referring to a characteristic quantity of the object image and, from this region, a characteristic quantity that characterizes a direction of lines within the object image along a second direction different from the second direction or a characteristic quantity that characterizes the object image as a single physical quantity is calculated. A verification unit at least verifies the characteristic quantity of the object image against that of a reference image along the second direction.

摘要： An error correction circuit includes a first error correction operation circuit subjecting to error correction a code of a line of a PI system in a data block including a product code that is stored in a buffer memory, and a second error correction operation circuit subjecting a PO-system line code to error correction. Data corrected by the first error correction circuit is transferred to the second error correction operation circuit at a second syndrome calculation circuit including a storage element storing a development of a syndrome calculation. Whenever PI-system line data corrected is received, the second syndrome calculation circuit reads corresponding data from the storage element and calculates a syndrome and overwrites the obtained value on old data stored in the storage element.

摘要： In order to acquire a suitable fingerprint image by correcting an elongated fingerprint image, a line sensor acquires fingerprint image as a plurality of line-shaped images. A computation unit computes a similarity value by use of an evaluation function for evaluating the degree of similarity between the line-shaped images. The similarity value represents the degree of similarity between a first line-shaped image and a second line-shaped image which serve as a similarity evaluation target and are included in the plurality of the line-shaped image. A compression unit compresses the first line-shaped image and the second line-shaped image when the similarity value is equal to or larger than a predetermined threshold value to generate a new line-shaped image. A generation unit generates the entire fingerprint image by combining the new line-shaped image with the other line-shaped images.

摘要： An image pickup device receives an incident light by way of the color filter that also transmits an infrared light component. For the purpose of correcting an infrared light component contained in an output signal, a control unit adds correcting infrared light components to image signals of multiple colors supplied from the image pickup device, respectively. To remove the infrared light components contained in the output signals, the correcting infrared light components are subtracted from the image signals of multiple colors supplied from the image pickup device. The control unit switches between an addition processing where an infrared light component is added and a subtraction processing where the infrared component is subtracted, according to a predetermined condition.
