Abstract: An electronic camera adopts an image pickup and optical system of a mirror scan type in which a mirror for scanning is disposed at a forward side of a taking lens. A line image sensor relatively scans an object while rotating the mirror to perform photographing. When controlling the exposure, the taking lens is moved synchronously along with rotation of the mirror to adjust the focal position thereof each time a slender sub-image of the object is picked up by the CCD. Driving the taking lens to focus the sub-image each time of scanning the sub-image enables picking up an entirety of the object image perfectly in a focused state.

Abstract: A camera shoots an image of a two-dimensional object by a line sensor for main scanning and a rotation scanning mechanism for secondary scanning. The image pickup angle range in the secondary scanning direction is altered according to modification of the focal length of the objective lens by a zooming mechanism. The angular velocity of secondary scanning is altered according to the angular position of subscanning and the focal length so that the image pickup range on the object plane of one line is substantially equal over the entire area of the image pickup angle range. Thus, a line sensor camera is provided that can photograph an image with no distortion in the secondary scanning direction.
