Abstract

PURPOSE:To enable effective self-diagnosis of a camera by displaying an error value obtained by comparing each color channel output of a color television camera and signals of each part with the reference values on a vedeo monitor. CONSTITUTION:Outputs R.G.B of each color channel of a color television camera are selected by a selector SEL1 and given to an input of a differential amplifier DA through a selector SEL2. Only the output G is applied to other input of DA through a selector SEL3. Output levels L1-Ln of each part of the camera, voltages V1-Vn and a control pulse P are connected to an SEL2, an SEL3 through an SEL4. Each error signal that uses as G a reference value is obtained from DA. This is AD-converted and applied to a CPU. The CPU stores the error value in an RAM basing on a program from an ROM. The contents of the RAM are converted to character signals by a character generator CG, and mixed with video signals Sv in a mixer MIX, and displayed on a video monitor VM.
