Patent ID: 8854487

Claim:
An imaging apparatus comprising: an image sensor configured to convert light incident through a lens into an electric signal; an image sensor driver configured to drive the image sensor in a first mode and a second mode different from the first mode in a driving method; a light metering value acquisition unit configured to acquire a light metering value from an electric signal output from the image sensor; an exposure controller configured to control an exposure amount according to a first program diagram to be used in the first mode and a second program diagram to be used in the second mode based on the light metering value acquired by the light metering value acquisition unit to obtain an appropriate exposure amount; and a focus controller for performing a focusing operation based on the electric signal output from the image sensor, wherein in response to switching the driving method of the image sensor from the first mode to the second mode by the image sensor driver, the exposure controller switches a program diagram from the first program diagram to the second program diagram, and the focus controller starts the focusing operation before the appropriate exposure amount according to the second program diagram is obtained, and wherein the focusing operation is a preliminary focusing operation to be executed before a focusing operation for finally focusing an object.
