摘要： In an imaging device having an electronic shutter, a shooting operation is achieved by the use of a CCD sensor, and a pre-shooting operation is conducted which accumulates signal electric charge such that the signal electric charge is discharged through a reverse transfer. In response to the amount of the signal electric charge thus discharged, the amount of exposure is determined (namely, the shutter speed and the iris value). By measuring the amount of the signal electric charge thus discharged for each predetermined range of a light receiving area, a multi-light measurement is achieved. The light receiving area has a plurality of photoelectric converter elements of the MOS capacitor type disposed therein and is subdivided into a plurality of areas which are insulated from each other. The pre-shooting operation is conducted which accumulates signal electric charge in the photoelectric converter elements such that the signal electric charge is discharged to the side of the substrate for each subdivided area. In response to the amount of the signal electric charge thus discharged, the amount of exposure is determined (namely, the shutter speed and the iris value). By measuring the amount of the signal electric charge thus discharged for each subdivided area, the multi-light measurement is achieved.
