To capture an image of object at long distance, viewing direction of the camera must be controlled when long-focal length is used. Therefore, there is method of control viewing direction at high-speed using galvanometer scanner. In this method, vibration of the mirror influences captured image due to mechanical motion. To get image of an object without mechanical motion, a camera should get an image of entire field of view. Then, object image can be got by clipping it from the image of entire field of view. In this method, camera must get also information other than the object at once to capture an entire image with wide range. Therefore, the object image is low-resolution because a number of image sensor's pixel which contributes the object is few. Thus, we propose a camera which has controllability of viewing direction and can capture highresolution image without mechanical motion based on computational imaging. By using this camera, it is possible to control at high-speed. Moreover the camera has no influence of vibration. We did a simulation and confirmed that the proposed camera which has controllability of viewing direction got highresolution image of an object without mechanical motion.
