ABSTRACT:
In order to realize a photometry/ranging solid state image pick-up device having high performance AE and multi-point functions by a single chip, a plurality of ranging photoelectric conversion element columns1A to7A and1B to7B for multi-point ranging and automatic focusing of a plurality of positions in a photographing area, spot photometry photoelectric conversion elements S1to S7for spot photometry of a plurality of ranging positions, and a whole area photometry photoelectric conversion element WO for photometry of a whole of the photographing area are integrated on the same semiconductor substrate107.By comparing a spot photometry value with a whole area photometry value, it becomes possible to distinguish between a front light scene and a rear light scene.
