Abstract

PURPOSE:To enable to adjust the white balance during pickup of general objective, without picking up white pattern, by picking up the objective through opaque filter, in adjusting the white balance. CONSTITUTION:The light passes through the lens 1 and it is irregularly reflected on a filter disc 2, and the output enters the pickup tubes 4, 5, 6 of red, green and blue color, via an optical system 3. Further, the output of the red, green and blue pickup tubes 4, 5, 6 is amplified with respectively red, green and blue video signal amplifiers 7, 8, 9 and the output is transmitted via respectively red, green and blue output terminals 12, 13, 14. In this case, control is made so that each video signal level can be equal with the operation of an automatic white balance adjusting circuit 12 consisting of the red- green and blue-green level difference detectors 10, 11.
