Abstract: There is provided with an image pickup apparatus including a detection unit configured to perform a flicker detection operation to detect flicker based on a plurality of images captured by an image sensor, and a control unit configured to control the image sensor based on detected flicker information. The detection unit configured to perform first detection of the flicker detection operation at a time that is different from a time at which an image pickup preparation instruction is received and different from a time at which an image pickup instruction is received whilst live view images are displayed. In the case that a flicker is detected in the first detection, the control unit configured to control exposure of the image sensor in a charge accumulation period to reduce an influence of the flicker for live view display on display means after the first detection.

Abstract: A control apparatus includes an independently exchangeable first circuit board that has an electric component and a non-volatile first storage unit; a second circuit board that has an electric component, a non-volatile second storage unit, and a third storage unit; and a controller that accumulates and stores information corresponding to an imaging count in the third storage unit at a first timing that corresponds to imaging performed by the image capture apparatus, and causes information corresponding to the information stored in the third storage unit to be stored in the first or second storage unit at a second timing that occurs at a longer interval than the first timing. The controller stores the information corresponding to the imaging count in the third storage unit after comparing information regarding the imaging count stored in the first and second storage units.

Abstract: An information processing apparatus and an information processing method are capable of correctly selecting data to be deleted, without a user having to perform a troublesome operation. In a backup operation, a determination is made for each image file as to whether a predetermined condition is satisfied. If the condition is satisfied, image files are backed up, and storage priority levels defined for these image files are reduced in accordance with a rule predefined by a user. The storage priority level is a measure indicating the priority of keeping an image file in a storage unit. The higher the storage priority, the lower the probability that image files are deleted. The storage priority levels are changed depending on whether image files have been backed up and depending on the number of times image files were backed up.

Abstract: An image pickup apparatus able to reliably detect a power supply abnormality even in an arrangement in which power supplies are managed by using a communication unit of single system. The image pickup apparatus includes a recording unit for writing image data onto a recording medium, and a power supply control unit for selecting and executing either a monitoring operation to monitor a state of a power supply for a camera main unit or a communication operation to communicate with a power supply for an accessory unit. The power supply control unit selects and executes the monitoring operation while the recording unit is performing an image data writing operation.
