20090034847 | Image processing apparatus, image processing system, image processing method, and image forming apparatus - 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. | 02-05-2009 |
20090067724 | IMAGE MATCHING APPARATUS, IMAGE MATCHING METHOD, AND IMAGE DATA OUTPUT PROCESSING APPARATUS - In an image matching apparatus of the present invention, when a document type discrimination section that discriminates a document type determines that a target document is an N-up document on which plural document images are laid out, a resolution conversion section that converts a resolution of image data into a default resolution before features are extracted from the image data converts a resolution of image data of the target document into not the default resolution but a resolution which varies depending on the number of document images laid out on the target document and a document size of the target document. This makes it possible to determine a similarity to a reference document with high accuracy even in a case where each document image included in the target document to be matched is reduced in size from its original document image, i.e., in a case of an N-up document. | 03-12-2009 |
20090067727 | IMAGE MATCHING APPARATUS, IMAGE MATCHING METHOD, AND IMAGE DATA OUTPUT PROCESSING APPARATUS - In an image matching apparatus of the present invention, only a connected region in which the number of pixels included therein exceeds a threshold value, among connected regions that are specified by a labeling process section, is sent to a centroid calculation process section from a threshold value processing section, and a centroid (feature point) of the connected region is calculated. When it is determined that a target document to be matched is an N-up document, the threshold value processing section uses, instead of a default threshold value, a variant threshold value that varies depending on the number of images laid out on the N-up document and a document size that are found and detected by an N-up document determination section and a document size detection section. This makes it possible to determine a similarity to a reference document with high accuracy even in a case of an N-up document, i.e., a case where each target image to be matched is reduced in size from an original image. | 03-12-2009 |
20090080783 | IMAGE DATA OUTPUT PROCESSING APPARATUS AND IMAGE DATA OUTPUT PROCESSING METHOD - In an image data output processing apparatus of the present invention, an image matching section is capable of determining whether a similarity exists between each image of an N-up document and a reference document when input image data is indicative of the N-up document. An output process control section is capable of regulating an output process of each image in accordance with a result of determining whether the similarity exists between each image of the N-up document and the reference document. This allows detecting with high accuracy a document image under regulation on the output process and regulating the output process, when the input image data is indicative of an N-up document and includes the document image under regulation on the output process. | 03-26-2009 |
20090096768 | DISPLAY SYSTEM AND METHOD FOR DETECTING POINTED POSITION - 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. | 04-16-2009 |
20090122030 | DISPLAY SYSTEM AND METHOD FOR DETECTING POINTED POSITION - 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. | 05-14-2009 |

The display system includes an image analyzing section for analyzing the captured image obtained by the capture to find reference light areas in the display apparatus and to detect the desired position on the display screen based on positions of the reference light areas in the captured image. The display apparatus also includes a blinking controlling section which controls blinking conditions of all the backlight units in the display apparatus to differ a blinking condition of two or more reference light area backlight units from that of the other backlight units. This allows properly detecting the desired position on the display screen pointed by the operating device. | 06-11-2009 |
20090214116 | IMAGE PROCESSING METHOD, IMAGE PROCESSING APPARATUS, IMAGE FORMING APPARATUS, AND STORAGE MEDIUM - In the image processing apparatus of the present invention, when a document is read, a document matching process section determines whether the document is similar to a reference document or not. When the document is similar to the reference document, the document matching process section further determines whether the document has been zoomed (size of the document has been changed). When the document has been zoomed, an editing process section restores the size of the document to the size of the reference document. This provides an image processing apparatus capable of restoring the changed size of a document in a predetermined format such as a form document and an application document to its original size. | 08-27-2009 |
