  • Patent number: 11750938
    Abstract: An image pickup apparatus that is capable of picking up an image that effectively blurs a background easily. The image pickup apparatus including at least one processor and/or circuit configured to function as following units. A generation unit generates simulation images that simulate defocus states of background in cases that an object is picked up at different object distances based on a preliminary pickup image generated by picking up the background without including the object. A setting unit sets evaluation frames to the simulation images, respectively. A calculation unit calculates defocus-state evaluation values of the evaluation frames. A notification unit notifies of information about an object position at which the defocus state becomes optimal based on the defocus-state evaluation values.

  • Patent number: 9794464
    Abstract: In an image capturing system, an image capturing apparatus transmits information indicating set capturing conditions to an information processing apparatus. The information processing apparatus obtains a recovery filter corresponding to predetermined capturing conditions based on the information, and transmits the recovery filter to the image capturing apparatus. Upon receiving the recovery filter corresponding to the predetermined capturing conditions from the information processing apparatus, the image capturing apparatus stores the filter in a storage device. Upon obtaining an image signal by capturing, the image capturing apparatus performs recovery processing by applying the received recovery filter to the image signal.
