  • Patent number: 11800241
    Abstract: The present technology relates to an interchangeable lens and a method for controlling the same capable of starting shooting in consideration of mechanical fluctuations after a diaphragm is driven, a shooting apparatus, and a camera system. An interchangeable lens includes a diaphragm, a diaphragm driving unit that drives the diaphragm, and a lens control unit that transmits diaphragm driving information including stabilization time information of the diaphragm to a shooting apparatus when the diaphragm driving unit drives the diaphragm. The present technology is applicable to lens-interchangeable digital cameras, and the like, for example.

  • Patent number: 9325912
    Abstract: An image processing apparatus including circuitry configured to cause an aperture diaphragm to move from a starting position toward first and second diaphragm positions of the aperture diaphragm such that the aperture diaphragm reaches the first diaphragm position at the beginning of an exposure period. The circuitry is further configured to cause the aperture diaphragm to move from the first diaphragm position to the second diaphragm position during the exposure period.
