Abstract

The present invention is directed to performing imaging processing for dividing a video signal obtained by an imaging unit into a plurality of areas, and detecting in parallel respective evaluation values of video signals of the plurality of areas, reducing the video signal obtained by the imaging unit, detecting an evaluation value of the reduced video signal, and controlling an operation of the imaging apparatus using either the evaluation values of video signals of the plurality of areas or the evaluation value of the reduced video signal.

First claim

What is claimed is:

1. An imaging apparatus comprising:
a division unit configured to divide an image signal obtained by an imaging unit into a plurality of areas;
a first detection unit configured to detect in parallel respective evaluation values of image signals of the plurality of areas;
a reduction unit configured to reduce the image signal obtained by the imaging unit;
a second detection unit configured to detect a further evaluation value of the reduced image signal,…
