The endoscope has a signal-reading processor that successively reads image-pixel signals, obtained by light passing through a color filter, from an image sensor at regular intervals. A video processor (10) outputs video signals and still image signals to peripheral equipment. A still-image signal processor generates still image signals based on the one frames worth of image-pixel signals obtained in the single exposure. The output processor outputs the one frames worth of image-pixel signals obtained in the single exposure to the equipment while the still image signals are generated. Independent claims are also included for the following: (1) an apparatus for processing image signals obtained by an electronic endoscope (2) a method for processing image signals obtained by an electronic endoscope.
