Abstract:
1. A television camera comprising: an optical system; and a central processing unit (CPU) that controls a lens iris of the optical system, wherein the television camera captures a white subject, and adjusts a detected video signal balance, wherein the CPU adjusts a video signal of the white subject to be converged with a plurality of predetermined signal levels through the control of the lens iris of the optical system, in order to adjust the detected video signal balance, and wherein the CPU sequentially adjusts the lens iris so that a level of a G signal becomes at least three levels, which are a highlight balance level, a dark balance level, and a gamma balance level, through the control of the lens iris of the optical system, and aligns levels of an R signal and a B signal with respect to the G signal for each signal level, in order to automatically adjust the detected video signal balance.
