Abstract

See full text

An image pickup apparatus which is capable of shortening a time period required for photometric measurement and obtaining an accurate photometric measurement value when there has been a shift from a photometric measurement operation using an image pickup device to a photometric measurement operation using a linear photometric sensor. When there has been no shift from a photometric measurement operation by the image pickup device to a photometric measurement operation by the photometric sensor, the photometric sensor performs a first photometric measurement operation for a plurality of times, and when there has been a shift from a photometric measurement operation by the image pickup device to a photometric measurement operation by the photometric sensor, a second photometric measurement operation is performed for a smaller number of times than that of the first photometric measurement operation according to a result of photometric measurement performed by the image pickup device.
