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.
