摘要： To compose an image from a plurality of partially overlapping images, both positional movement and perspective transformation are performed using pyramidal data structures. After the positional movement is determined for a unit block of one partially overlapping image to match a corresponding block, a set of perspective transformation parameters is determined based upon the positional movement. The partially overlapping images are composed into a single image while the partially overlapping images efficiently undergo the perspective transformation according to the above determined parameters.

摘要： A camera system includes a display monitor which displays an image of an object, taken by an optical unit, on a screen of the monitor. A reading unit reads a preceding image and a current image among a plurality of partially overlapping images, from a memory device, the preceding image and the current image containing a common element. A determining unit determines a positional relation between the preceding image and the current image based on a common pattern derived from the common element in the two adjacent images read by the reading unit. A displaying unit displays an image indicating a boundary of the preceding image on the screen of the monitor at a shifted position according to the positional relation determined by the determining unit, with the current image concurrently displayed on the screen of the monitor.

摘要： An intensity value is independently estimated based upon interpolated values as well as measured sensor values according to the location of an individual sensor within a sensor unit. The interpolated values are in either CrCb or RGB values while an estimated intensity value is in Y value. The independent intensity value substantially improves color resolution.

摘要： A calibration method is for a photographic device that photographs an object through a transparent body. The calibration method includes: acquiring a first photographic image by photographing the object without interposing the transparent body; acquiring a second photographic image by photographing the object through the transparent body; calculating an absolute positional deviation that indicates a deviation in coordinates of an image of the object due to the transparent body based on coordinates of an image of the object on the first photographic image and coordinates of an image of the object on the second photographic image; calculating a correction parameter for calibrating the absolute positional deviation; and storing the correction parameter in the photographic device.

摘要： A calibration method calibrates a stereo camera. The calibration method includes: measuring a relative position between the stereo camera and an object that is placed so as to fall within an image capturing area of the stereo camera; acquiring a captured image that is captured by the stereo camera and includes the object; and determining a calibration parameter for calibrating the stereo camera based on the relative position and the captured image.

摘要： A range-finding system includes two imaging devices to capture multiple images from two different viewpoints and a parallax calculator to calculate parallax based on the multiple images captured by the two imaging devices. The parallax calculator includes an estimation unit to estimate a correction value based on the amount of image deviation in a lateral direction corresponding to pixel position in the images captured by the two imaging devices and a correction unit to correct a pre-correction parallax or an image based on the correction value estimated by the estimation unit.

摘要： An image taking unit including a lens array, a light shielding member, and an image taking unit that acquires a compound eye image of a vein pattern of a living body held at a lens array. A shift estimation unit estimates an image shift amount between ommatidium images of the compound eye image. An image restructuring unit restructures a single image from the compound eye image by using the image shift amount. In at least one embodiment, a size correction unit corrects the size of the restructured single image with a magnification ratio determined by the estimated image shift amount and an image shift amount stored in a registration pattern storage unit so as to correspond to a registration pattern. As a result, it is possible to perform personal authentication while compensating influences due to fluctuations in a subject distance.
