Document Type and Number:
Japanese Patent JP6824664
Kind Code:
B2
Abstract:
An image pickup apparatus being capable of performing a photometry process under a suitable condition and of achieving high-speed continuous photographing. A first drive, which accumulates and reads an electric charge with an image sensor for a photometry process, and a second drive, which accumulates and reads an electric charge to obtain an image signal for a static image, are alternately repeated during continuous photographing. A photometry process is performed based on the electric charge read by the first drive. An aperture value for obtaining the image signal of an (N+1)th frame is calculated based on a result of the photometry process during accumulation for obtaining the image signal of an N-th frame. A control unit controls a diaphragm based on the calculated aperture value and a predetermined aperture value during reading of the electric charge for obtaining the image signal of the N-th frame.
