Abstract
The present electronic endoscope apparatus makes it possible to select either of a conventional pixel mixing and reading system and a new all-pixel reading system. For example, an electronic endoscope apparatus having a pixel mixing and reading system circuit section is configured so that an all pixel reading system circuit board for reading all pixel signals out of a CCD while using an opaque period can be selectively set to the electronic endoscope apparatus, it is judged by a microcomputer whether the all pixel reading system circuit board is present, and when the circuit board is present, an all-pixel reading system operation is executed. Moreover, it is permitted to use the pixel mixing and reading system and all-pixel reading system circuit sections as standard sections, normally execute all-pixel reading system operations, and when, for example, a freeze switch is pressed at power-on, pixel mixing and reading system operations may be executed. Furthermore, it is displayed on a monitor by a character or icon whether the pixel mixing and reading system or all-pixel reading system is currently operated.
