Abstract
An imaging system including a frame rate setter and an exposure evaluator. The frame rate setter sets a frame rate used in a focusing operation. The frame rate is set faster than a normal frame rate. The exposure evaluator evaluates the exposure of a focusing image based on pixel signals read out from a focusing image area at the frame rate. The frame rate is reduced when the exposure is evaluated as an underexposure and the focusing operation is carried out at a reduced frame rate.
Claims6
An imaging system, comprising:
- a frame rate setter that sets a frame rate used in a focusing operation, said frame rate being set faster than a normal frame rate;
- and
- an exposure evaluator that evaluates the exposure of a focusing image based on pixel signals read out from a focusing image area at said frame rate;
- said frame rate being reduced when said exposure is evaluated as an underexposure and said focusing operation being carried out at a reduced frame rate.
