Electronic endoscope apparatus

An apparatus for recording a still-image according to an electronic endoscope apparatus including a video-scope with an image sensor, comprising:

• a high-speed electronic shutter processor that reads image-pixel signals from said image sensor at a still-image electronic shutter speed, which corresponds to a reading time interval shorter than a predetermined time interval defined for displaying a moving-image;
• a still-image light-amount controller that controls a light-amount adjuster for adjusting an amount of light for illuminating a subject, such that the light-amount becomes a standard light-amount corresponding to a recording of the still-image, when a series of actions for recording a still-image as data is started;
• and
• a recording processor that records the still-image as data in accordance with the still-image electronic shutter speed when the light-amount becomes the standard light-amount.

A computer program product for recording a still-image according to an electronic endoscope apparatus including a video-scope with an image sensor, comprising:

• a high-speed electronic shutter processor that controls said image sensor so as to read image-pixel signals from said image sensor at a still-image electronic shutter speed, which corresponds to a reading time interval shorter than a predetermined time interval defined for displaying a moving-image;
• a still-image light-amount controller that controls a light-amount adjuster for adjusting an amount of light for illuminating a subject, such that the light-amount becomes a standard light-amount corresponding to a recording of the still-image, when a series of actions for recording a still-image as data is started;
