  • Patent number: 11009675
    Abstract: An imaging apparatus includes a focus detector configured to perform a focus detection based on a signal output from the image sensor corresponding to the first imaging, a calculator configured to calculate a first time corresponding to the second imaging, and a focus controller configured to perform a focus control for driving the focus lens to an in-focus position predicted at the first time based on a focus detection result. The calculator calculates the first time in accordance with whether the aperture control corresponding to the attached lens apparatus is a first aperture control for driving the aperture to a target aperture value via a predetermined aperture value from the aperture value before the aperture control or a second aperture control for driving the aperture to the target aperture value directly from the aperture value before the aperture control.

  • Patent number: 10230903
    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.

  • Patent number: 9692980
    Abstract: A digital camera includes a zoom function for supporting a user when performing a frame assist, and includes an operation switch for instructing startup and completion of the zoom function on an operation unit. A system control unit stores a zoom position in a memory and varies the zoom position in a wide angle position according to a preset zoom-out drive amount when an instruction to startup the zoom function is given by the operation switch. Then, when the instruction to end the zoom function is given by the operation switch, the system control unit executes a zoom-in operation by returning to the zoom position that is stored in the memory.
