  • Publication number: 20130271426
    Abstract: Provided is a touch panel system (1) capable of reliably removing a wide variety of noises. The touch panel system (1) includes a main sensor (31) which detects a touch operation, a sub sensor (32) which does not detect a touch operation but detects a noise component, and a subtracting section (41) which subtracts, from an output signal of the main sensor (31), an output signal of the sub sensor (32). The subtracting section (41) performs a subtracting operation to remove a noise component from the output signal of the main sensor (31), thereby extracting a signal derived from the touch operation itself.

In accordance with the maximum luminance value that is thus stored in the maximum luminance storage section and that each of the areas has, a BL candidate value calculating section and a BL luminance difference adjusting section determine an emitted-light luminance in a target area such that a difference between the backlight luminance in the target area and the backlight luminance in its adjacent area is not more than a tolerance value.

  • Patent number: 7697733
    Abstract: An image collating apparatus includes a storage device and a processor. The storage device stores data representing a sensing image, data representing a template image, and a program. The processor detects exclusion areas in the sensing image to be excluded from the image collation operation based on classification of image patterns. The processor determines whether or not the sensing image and the template image are derived from the identical object by performing template-matching operations to evaluate similarity between the template image and partial images of the sensing image in different levels with increasing the size of area covered by the partial image to be matched with the template image level by level. At least in one level the processor performs the template-matching operation with respect to the partial image where the exclusion areas are excluded.

  • Patent number: 7512275
    Abstract: When first and second images are input, a partial image feature calculating unit calculates feature values of partial images of the two images. A maximum matching score position searching unit searches for a position of the second image that attains to the highest matching score with each of the partial images of the first image. A movement-vector-based similarity score calculating unit calculates similarity between the first and second images, using information related to that partial image whose movement vector has direction and length within a prescribed range, which movement vector representing positional relation between a reference position for measuring, for each of the partial images, the position of the partial image in the first image and the position of the maximum matching score corresponding to the partial image searched out by the maximum matching score position searching unit. The images as the object of collation may belong to the same category classified based on the feature values.

  • Patent number: 7492929
    Abstract: An image matching device capable of matching two images performs the following processes in order to shorten a processing time and reduce power consumption. Template matching is performed between a first image and a second image using a predetermined partial image of the first image, and the similarity between the two images is calculated. The similarity thus obtained is compared with a predetermined threshold. Only upon determination that the similarity obtained and the predetermined threshold neither coincide not fail to coincide with each other, the partial image used for template matching is gradually increased until the similarity and the predetermined threshold come to coincide or fail to coincide with each other. Then, template matching is performed again and the similarity between them is calculated.
