摘要： An identification apparatus that keeps the conditions for imaging uniform among successive identifications and requires a user to perform only a series of simple maneuvers. An identification apparatus comprising a guide member, a light source, and an imaging unit. The guide member includes a pattern or a structure that inspires a user to position his/her finger thereon or to approach his/her specific finger region thereto. A contact member such as a button switch is preferably located at a position in the guide member at which a fingertip is to be positioned. An optical opening is formed at a position coincident with a position at which a portion of a finger to be imaged for identification should be placed. The light source radiates near-infrared light through the portion of the finger to be imaged. The imaging means acquires an image of the finger, and the apparatus compares the image to previously registered images. The apparatus may also include dual light sources power saving functionality, and means for limiting the interference of external light sources.

摘要： A digital camera has an image sensor, and an optical system for focusing a scene on the image sensor. A zooming system is used for changing a zoom rate of the scene that is focused on the image sensor. By operating the zooming system during the recording of a series of images, each of the images has a different zoom rate and therefore a different level of detail and field of view. The images are combined to form one still image of super high resolution. The zoom rate between images is detected by using horizontal and vertical pixel intensity value projection distributions in both forward and backward prediction methods. Horizontal and vertical candidate projection distributions that are correlated to a range of possible zoom rates are compared with the horizontal and vertical projection distributions of the former and current images being processed to determine a least error match that is selected as the zoom rate between the adjacent images. Using the image to image zoom rate, a scaling factor is determined that is used for scaling each current image before overwriting the current image over the former images previously written to the image buffer. In this way, the detail of each image in the series is written to the image buffer and a super high resolution, wide angle still image is formed that can be stored and displayed.

摘要： In order to reduce the load on the operator in monitoring a moving object in the moving picture signal supplied from the imaging device, the signal is displayed in one region of the display device. The moving route of the moving object which has entered the view of the imaging device is extracted, based on the signal. The first image data showing the image of a moving route of an extracted moving object is generated, and the second image data showing the image of the moving object is generated based on the signal. The overlapped image of the image of the moving route and the image of the moving object is displayed in another region of the display device together with the extraction time of the image of the moving object. The processing above is repeated to other moving objects which enter the view later on. The overlapped images for different moving images thus extracted are displayed adjacent to each other in the region.

摘要： A method and an apparatus for searching character image in an image whether the characters are incorporated into an image or separately picked up from a flip card, which are difficult to be detected by the prior art. The invention enables the character strings thereby detected to be searched in a common framework without relying on the language or the character font. An image is chosen, a character region is detected from the frame of the chosen image on the basis of its shape, and a visual feature of the character area is extracted. On the other hand, a character string to be searched for which has been entered by a character input means is drawn as an image, and a visual feature is extracted from the character area image. The visual feature of the obtained character area and the visual feature of the character area image are matched to determine a level of similarity, and the character region containing a character string the level of similarity of which has been determined is outputted.
