PROBLEM TO BE SOLVED: To provide a solid-state image pickup device capable of measuring the quantity of smears and the quantity of blooming accurately and quickly in the one-frame period of the driving timing of image forming. SOLUTION: Photosensors a11 to anm are irradiated by a fixed light quantity, and then the electronic shutter for photosensors a11 to an1, a13 to an3... of odd-numbered lines is turned on by the image forming timing of the first field of one frame, and the electronic shutter of photosensors a12 to an2, a14 to an4... of even-numbers lines is turned off by the timing of the image forming of a second field. The arithmetic and logic unit 8 can accurately measure the quantity of average smears and the quantity of average blooming with high precision and quickly in one-frame period of the driving timing of image forming of a solid-state imaging element 10, based on the measurement of the quantity of a first signal in vertical registers 5a to 5n in the state where the charge readout is suspended, and the measurement of the quantity of the second signal in the vertical registers 5a to 5n in the state where the charge readout is suspended. |
