Imaging apparatus and imaging method which perform focus adjustment while performing live-view display
Abstract:
An imaging apparatus according to the present invention is an imaging apparatus performing live-view display when not performing the focus adjustment, and also when performing the focus adjustment, and includes: a focus adjustment brightness value calculation section comparing a first brightness value in the photometric area for the live-view display with a second brightness value in the photometric area for the focus adjustment, correcting the first brightness value according to a comparison result, and calculating a brightness value for obtaining the image data for the focus adjustment; an imaging section obtaining the image data by performing exposure using the brightness value calculated by the focus adjustment brightness value calculation section; a focus adjustment section performing the focus adjustment using the image data obtained by the imaging section, and a display section performing the live-view display using the image data obtained by the imaging section.
