Imaging apparatus and imaging method which perform focus adjustment while performing live-view display

摘要

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.

主权项

1. An imaging apparatus performing live-view display by generating image data using an exposure parameter calculated from a brightness value in a photometric area for the live-view display which is different from a photometric area for focus adjustment when not performing the focus adjustment, and performing the live-view display also when performing the focus adjustment, the imaging apparatus comprising:
a first calculating section for calculating a first brightness value in the photometric area for the live-view display; a second calculating section for calculating a second brightness value in the photometric area for focus adjustment; a comparison section for comparing a brightness difference between the first brightness value and the second brightness value with a specified value; a third calculation section correcting the first brightness value according to a comparison result from the comparison section; an imaging section obtaining the image data by performing exposure using the brightness value corrected by the third 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.
