Abstract
A simultaneous electronic endoscope apparatus which is capable of preventing the deterioration of the picture quality due to the difference of the saturation property in mixture signals. The apparatus comprises a charge coupled device provided with a plurality of color filters. Upper and lower pixel signals are mixed in a charge coupled device so as to form mixture signals. When the saturated state of a mixture signal is detected, the gain of the mixture signal is multiplied by a preset coefficient so as to apparently cancel the saturated state. Alternatively two types of luminance signals may be formed by combining the plurality of mixture signals formed on each horizontal scanning line. When the saturated state of a luminance signal is detected, the gain of the luminance signal is amplified so that the level thereof is the same as that of the other luminance signal, thereby apparently cancelling the saturated state.
