Abstract
A solid-state image pickup element includes an image signal combining part configured to combine a first image signal read from a pixel portion at a first timing, and a second image signal read from the pixel portion at a second timing, which is different from the first timing, to generate a third image signal.
Claims12
A solid-state image pickup element, comprising:
- a pixel portion in which a plurality of pixels are arranged;
- and
- at least one processor, included in the solid-state image pickup element, programmed to function as:
- an image signal combining part which combines a first image signal read from the pixel portion at a first timing, and a second image signal read from the pixel portion at a second timing, which is different from the first timing, to generate a third image signal;
- a signal level analysis part which analyzes a signal level of the first image signal;
- a memory which stores the first image signal;
- and
- a controller which controls the signal, level of the first image signal and a signal level of the second image signal to be different from each other based on a result of the analysis of the first image signal by the signal level analysis part,
- wherein the image signal combining part generates the third image signal by combining the second image signal read from the pixel portion with the first image signal stored in the memory, and
- wherein the third image signal has a ratio between a minimum expressible luminance and a maximum expressible luminance that is larger than that of the first image signal and that of the second image signal.
