摘要：
An image capturing apparatus for acquiring images having high dynamic range. The image capturing apparatus includes CCD consisting of a first photo detector for detecting light from central area of a subject, a second photo detector for detecting light from marginal area of the subject, a photometry sensor for measuring brightness of the central and the marginal areas of the subject, and a sensitivity control unit for controlling sensitivity of the first photo detector based on the brightness of the central area measured by the photometry sensor and controlling sensitivity of the second photo detector based on the brightness of the marginal area measured by the photometry sensor.
