ABSTRACT:
A video camera comprising a taking lens, an image taking circuit which generates a video signal by receiving a light having passed through the taking lens, a knee correction circuit which compresses a video signal generated by the image taking circuit and having a level as high as or higher than a predetermined level, a detection circuit which detects a luminance distribution condition of a field, a pedestal adjusting circuit which adjusts a black level of the video signal generated by the image taking circuit and a control circuit which changes a compression method of a video signal in the knee correction circuit and an adjusting method of the black level in the pedestal adjusting circuit according to a luminance distribution condition of a field detected by the detection circuit. According to the present invention, it is possible to perform various controls in response to a luminance condition of a field.
