    摘要: An image matching device includes a section calculates feature points on an input document image, a section that calculates features of the input document image in accordance with a relative position between the calculated feature points, and sections for comparing the calculated features of the input document image with features of a reference document image to determine whether the input document image is similar to the reference document image. When it is determined that the input and reference documents are similar, a document discrimination section determines a position of an image on the input document and similar to the reference document image, in accordance with the positions of the coordinates of the feature points on the input document and on the reference document.

    摘要: At least two infrared light-emitting areas are displayed within a display screen of a liquid crystal display apparatus. The infrared light-emitting areas are areas for emitting light having a wavelength in the infrared region. Then, an image is captured by an operating device in the direction of a position pointed by the operating device. A position on the display screen that is pointed by the operating device is calculated based on the positions of the infrared light-emitting areas that are included in the captured image. This arrangement makes it possible to appropriately calculate the position on the display screen that is pointed by the operating device, independently of the distance between the operating device and the display screen of the liquid crystal display apparatus.

    摘要: In a card serving as an external storage device to be inserted into a digital color multi-function printer, features of a reference image and processing rule information indicating processing content to be applied to input image data judged to be similar to the reference image are prestored. Then, in cases where the input image data is judged to be similar to the reference image, the content of a process to be performed on the input image data is controlled in accordance with the processing rule information corresponding to the reference image. This makes it possible to save users the trouble of setting the content of a process to be performed on input image data, and to prevent a shortage of memory capacity of a memory of the image processing apparatus even in cases where there is an increase in the number of reference images.

    摘要: A plurality of infrared-light-emitting areas are displayed in a display screen of a liquid crystal display apparatus in a method that allows each of the infrared-light-emitting areas to be distinguished. Then, an image in a direction of a pointed position is captured by an operating device. Based on a result of distinguishing each of the infrared-light-emitting areas and a position of each of the infrared-light-emitting areas, a pointed position on the display screen is calculated. This makes it possible to properly detect the pointed position on the display screen pointed by the operating device, regardless of (i) a distance between the operating device and the display apparatus and (ii) a rotation angle of the operating device around an axis in an image capture direction of the operating device.

    摘要: A plurality of infrared-light-emitting areas are displayed in a display screen of a liquid crystal display apparatus in a method that allows each of the infrared-light-emitting areas to be distinguished. Then, an image in a direction of a pointed position is captured by an operating device. Further, a predetermined number of infrared-light-emitting areas are selected from the infrared-light-emitting areas included in thus captured image. Based on a result of distinguishing each of the selected infrared-light-emitting areas and a position of each of the selected infrared-light-emitting areas, a pointed position on the display screen is calculated. This makes it possible to properly detect the pointed position on the display screen pointed by the operating device, regardless of a distance between the operating device and the display apparatus.
