PURPOSE:To obtain a pickup pattern in which an original picture is not deteriorated by applying a command voltage obtained from an image pickup signal to a transparent film arranged onto a photodetection face of a photosensing section from a transmission quantity control section so as to control the quantity of transmission of an incident light to the transparent film by each picture element depending on the quantity of the command voltage. CONSTITUTION:An address of a picture element of an excess incident light stored in an address decoder 19 and a control data stored in a data decoder section 21 are inputted to the transmitted light quantity control section 9 corresponding to the picture element as a command signal by a distribution gate 23. Thus, in applying a voltage to an electrode 8a of the transparent film 8 from the transmitted light quantity control section 9, since the chemical substance 8c of the transparent film base 8b is changed in proportion to the command voltage in its arranging state, the transmittivity of the incident light 8d is changed and it is possible to control so as to give a proper incident luminous quantity to all photodiodes 4. Thus, a pickup pattern with good quality is obtained even from a picture having a large difference in the luminous quantity distribution from a metallic glitter work very close to the mirror face reflection.
