Abstract
PURPOSE: To obtain a good picture inside as well as outside without making a dynamic range narrow by irradiating a solid image pickup device with a bias light and controlling the bias charge generated by this irradiation.
CONSTITUTION: The optical image of object 11 is focused onto the photosensitive part of CCD13 through image pickup lens 12. Bias light source 19 using a LED is provided near the photosensitive part of CCD13 and is so constituted that light source 19 may irradiate this photosensitive part uniformly. Output signals of CCD13 are amplified into a prescribed level by amplifier 14 and are applied to process circuit 15 and are added to synchronizing signals there and are subjected to DC reproducing, gamma correction, pick signal clip, etc., thereby obtaining standard TV signals. On the other hand, a part of the output of amplifier 14 is applied to detection circuit 16 and is detected, and after that, it has the phase shifted by 180° in polarity inversion circuit 17 and is applied to voltage control circuit 18. Circuit 18 controls a voltage applied to light source 19 and changes the output light quantity of light source 19.
