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.

1. A digital camera, comprising:an operation input means for starting and ending recording of a scene; an image sensing device for capturing a plurality of images of a scene as a dynamic image; a shift value determining means for determining amounts of shift in position between consecutive ones of the plurality of images due to movement of the camera during the recording; and a wide view image display means for displaying a wide view image obtained by connecting the consecutive images by overwriting a current one of said consecutive images with respect to a last one of said consecutive images by the amount of shift in position determined by said shift value determining means, wherein: said shift determining means uses global pattern matching between the consecutive images taking the projections of the intensity values of the pixels in the horizontal and vertical directions, and said wide view image display means sequentially displays wide view image that is formed from the start to the end of the recording.
