An image sensing apparatus includes an image input unit () for inputting an image, a detection unit () for detecting a state of movement of the image input unit () in an image input operation, a storage unit () for storing a plurality of images input by the image input unit () and movement information corresponding to the state of movement detected by the detection unit (), and an image generating unit () for generating an image from an arbitrary viewpoint position on the basis of the plurality of images and the movement information stored in the storage unit.

Virtual image sensing and generating method and apparatus

Convergence angle information and image information of video cameras is transmitted from a multi-eye image-taking apparatus having two video cameras through a recording medium to a displaying apparatus. A convergence angle of display units in the displaying apparatus is controlled in accordance with the convergence angle information of the video cameras, permitting an observer to observe natural images. Since the convergence angle information is made ahead of the image information, the convergence angle of the display units can be changed with a natural feeling.

Image display system

An image processing apparatus comprising a signal conversion circuit for changing input/output characteristics in accordance with a shift position of an image is arranged between a detection circuit for detecting a relative movement between a camera and an object to be photographed and an image shift circuit for shifting the image in accordance with a detection result of the detection circuit.
