Abstract:
A camera, comprising:a lens system to focus light from an object along an optical path through an aperture so as to form an image of the object on a focal plane; a regulating device for adjusting an opening area of the aperture so as to regulate an incoming light amount on the focal plane, wherein f-number of the lens system is changed in accordance with the adjusted opening area of the aperture; image pickup elements provided on the focal plane and for photoelectrically converting the light of the image so as to generate image signals, the image pickup elements arranged with a pitch of 7.0 &mgr;m or less; an optical low-pass filter for eliminating high frequency components of the light of the image; and a control device for controlling the filtering performance of the optical low-pass filter to change the degree of high frequency component elimination in accordance with the f-number of the lens system in case that the f-number is 5.6 or more so that a deterioration of an image quality caused by increasing the f-number is minimized.
