Abstract: An apparatus controls an image capturing apparatus that obtains, through automatic shooting, an image to be provided to a user. The apparatus evaluates a state of a subject, determines, based on a result of the evaluation, whether to cause the image capturing apparatus to perform shooting, obtains demand information that indicates demand tendencies of a user respectively for state types of the subject, and controls an operation of the determination based on the demand information. The apparatus controls the operation of the determination so that a frequency at which the image capturing apparatus performs shooting varies in accordance with magnitudes of demands for the respective state types of the subject.

Abstract: An image pickup apparatus whose function can be easily changed is provided. The image pickup apparatus, to which a mounting component part having a wireless IC tag can be attached, comprising at least one processor and/or circuit configured to function as following units, a reading unit configured to read information recorded in the wireless IC tag, an attitude determination unit configured to determine an attitude of the mounting component part, which is attached, with respect to the image pickup apparatus, and a function changing unit configured to change a function of the image pickup apparatus. In a case that the reading unit can read the information recorded in the wireless IC tag, the function changing unit changes the function of the image pickup apparatus according to the attitude of the mounting component part, which is determined.

Abstract: A display apparatus according to the present invention is to be fixed on a head of a user, and includes: an image sensor configured to be capable of changing focal distance; a display configured to display, as a display range, a part of an image which is captured by the image sensor; an orientation detector configured to detect an orientation of the display apparatus; and at least one memory and at least one processor which function as a control unit configured to control a position of the display range based on a change of the orientation detected by the orientation detector, and the focal distance.

Abstract: A display device configured to be used in a state of being fixed to a head of a user, includes: a camera; a display configured to display a part of an image captured by the camera as a display range; an orientation detection sensor configured to detect an orientation of the display device; a line-of-sight detection sensor configured to detect a line-of-sight of the user to the display; and a processor configured not to control a position of the display range based on the line-of-sight detected by the line-of-sight detection sensor in a case where a change amount of the orientation detected by the orientation detection sensor is smaller than a predetermined amount, and to control the position of the display range based on the line-of-sight in a case where the change amount of the orientation is larger than the predetermined amount.

Abstract: An image capturing apparatus capturing an object image based on a set time includes: a first state-changing unit setting an light emission unit in a first state with a light emission corresponding to image capturing, and in a second state with less power consumption than that in the first state; a second state-changing unit setting the apparatus to a third state where an image is captured, and in a fourth state with less power consumption than that in the third state; and a light emission determining unit that determines whether to cause the emission unit to emit a light for the next capturing. The second state remains until the next capture when it is determined not to emit a light. The change to the fourth state starts after it is determined not to emit a light. Then, the apparatus changes to the third state again for the next capturing.
