Abstract
An imaging system is provided that includes a target detector, a readout area determiner and a readout processor. The target detector detects a target subject from an effective pixel area of an image sensor. The readout area determiner defines a readout area within the effective pixel area, the readout area corresponding to a detected target. The readout processor reads out only pixel signals within the readout area. A partial area within the readout area is redefined as the readout area when the size of the original readout area is greater than a predetermined size.

An imaging system, comprising:
- a target detector that detects a target subject from an effective pixel area of an image sensor;
- a readout area determiner that defines a readout area within said effective pixel area, said readout area corresponding to a detected target;
- a readout processor that reads out only pixel signals within said readout area;
- and
- a partial area within said readout area being redefined as said readout area when the size of original said readout area is greater than a predetermined size.
A pixel signal readout method, comprising:
- detecting a target subject from an effective pixel area of an image sensor;
- defining a readout area within said effective pixel area, said readout area corresponding to a detected target;
- reading out only pixel signals within said readout area;
- and
- redefining a partial area within said readout area as said readout area when the size of original said readout area is greater than a predetermined size.
