Abstract
The invention relates to an electronic image pickup system that enables a wide image-pickup, and ensures that even when an image is printed, sufficient image quality and clearness are obtained from the center to as far as the margin of the image and the image of a subject is depicted with a sense of extension. The electronic image pickup system comprises an image-formation optical systemfor forming an image of a subject and an electronic image pickup devicelocated on an image side of the image-formation optical system for obtaining image information on the image. The angle between the farthest-off-axis chief ray incident on the farthest off-axis site on an image pickup plane of the electronic image pickup device and an axial chief ray incident on the center of the image pickup plane satisfies condition (1) for determining the angle of view suitable to obtain the sense to extension demanded for landscape photography and sharpness all over the image and condition (2) for allowing a light bundle incident on the image pickup device to be substantially vertically incident on the image pickup plane. The image pickup devicesatisfies condition (3) for determining the effective number of pixels on the image pickup device or the maximum number of recording pixels by signal processing.
