Abstract
A short duration of exposure is selected for the object for EVEN fields and a long duration of exposure is selected for the object for ODD fields by the electronic shutter, the obtained images being subsequently synthetically combined according to a synthetic reference levels in a dynamic range broadening mode. For the EVEN field, the duration of exposure is automatically controlled according to the brightness for high speed shutter operation. The level of REF is lowered when a small value is selected for the duration of exposure whereas the level of REF is raised when a large value is selected for the duration of exposure. In the case of a dark object that does not require any dynamic range, REF rises to get to the white clip level, when the mode is switched to an ordinary mode to increase the duration of exposure for both EVEN fields and ODD fields.
