摘要： A digital wide camera is capable of forming, in real time, a wide view still image from a dynamic sequence of images generated during a recording operation by panning the camera to capture a scene. The camera shoots each frame of the sequence with a certain angular field of view at 30 frames per second, for example. The wide view still image has an apparent field of angular view that is greater than that of the image of each frame. The images of the sequence are connected together by determining a shift in position between adjacent images and then overwriting each image to a wide view image buffer after shifting the image by the shift amount. Determining the shift amounts and overwriting the image buffer is accomplished in less time than the interval between shooting consecutive images so that the display of the wide view image can be updated in real time for a user's observation. The amount of shift in position is determined using global pattern matching between adjacent images by taking the projections of the intensity values of the pixels in the horizontal and vertical directions of the images being compared. The projections are subjected to collation processing to identify the amounts in shift in each direction.

摘要翻译： 数字宽相机能够实时地从通过平移相机拍摄场景而在记录操作期间产生的动态图像序列中形成广视图静止图像。 例如，相机以每秒30帧的特定角度视野拍摄序列的每一帧。 宽视角静止图像具有比每帧的图像的角度视图更大的明视场。 通过确定相邻图像之间的位置的偏移，然后在将图像移位移位量之后将每个图像重写为宽视图图像缓冲器，将序列的图像连接在一起。 确定移位量和覆盖图像缓冲器的时间比拍摄连续图像之间的间隔更短的时间完成，使得可以实时更新宽视图图像的显示以供用户观察。 通过拍摄正在比较的图像的水平和垂直方向上的像素的强度值的投影，来确定相邻图像之间的全局模式匹配的位置偏移量。 对投影进行核对处理以识别每个方向上的偏移量。

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.
