There is disclosed a video camera including a material element, arranged in
a photographing optical system, for controlling the light transmission factor or
amount, an image pickup element for receiving an optical image transmitted through
the material element at the position of an imaging plane, and converting the optical
image into an electrical signal, and a correction unit for correcting the light
transmission factor wavelength dependency of the material element in accordance
with the light transmission factor characteristics or light transmission amount
characteristics of the material element.
