The present disclosure relates to systems and methods for exposure control. The systems and methods may obtain a target frame brightness value of the image. The systems and methods may also obtain an exposure mode of the electronic device. The systems and methods may also obtain an exposure table corresponding to the exposure mode. The systems and methods may also determine a target value, corresponding to the target frame brightness value, for each of the one or more exposure parameters based on the exposure table. The systems and methods may also adjust one or more of the at least one lens, the at least one exposure-time controller, and the at least one sensor according to the target values of the one or more exposure parameters.

The present disclosure is directed to preventing an operation from being performed in an operation mode that is not intended by a user. In an image capturing apparatus, a moving image lever is an operation member for issuing an instruction to change an operation mode to a moving image capturing mode that is a state where a moving image is recordable. In order to avoid unintentional change of the operation mode to the moving image capturing mode due to an erroneous operation on the moving image lever, a setting is made to enable and disable an instruction that is issued by operating the moving image lever. If the setting is changed to disable while the image capturing apparatus is operating in the moving image capturing mode, a microcomputer changes an operation mode to a still image capturing mode.

An image capturing apparatus, comprises an instructing unit capable of issuing an instruction for an image capture preparation operation and an instruction for an image capture operation, a metering unit configured to meter brightness of a subject, a calculating unit configured to calculate values of exposure parameters based on a metering result, an acquiring unit configured to acquire information related to an image capture lens; and a controlling unit configured to, when image capture is performed with light emitted by a light emitter, control the calculating unit so as to make different a calculation method for the values of the exposure parameters at the time of issuance of the instruction for the image capture preparation operation based on the information related to the image capture lens.

An information processing device including a light source control unit that controls a light source that irradiates an eye with light; and an exposure control unit that controls exposure for imaging the eye. The light source control unit sets a state of the light source to an on state or an off state at a time when the exposure is not performed.

A subject information acquisition section acquires a subject distance difference, which is distance difference between a main subject and a subject farthest from the main subject, on the basis of an imaging signal sent from an imaging element. A program diagram storage section stores a first program diagram where an aperture value is fixed at an open aperture value at a first amount of exposure EV1 or less, and stores a second program diagram where an aperture value is fixed at an open aperture value at a second amount of exposure EV2, which is greater than the first amount of exposure EV1, or less. An imaging exposure determination section selects the second program diagram in a case where an APD filter is disposed on the optical path and a case where the subject distance difference is equal to or greater than a threshold value and there is an imaged scene in which a blurred image tends to occur, and selects the first program diagram in a case where the subject distance difference is less than the threshold value and there is an imaged scene in which a blurred image is hard to occur.

An imaging apparatus includes an imager configured to capture an object image, a photometric unit configured to measure a light amount incident on the imager, an acquisition unit configured to acquire a plurality of data indicating a relationship between the light amount incident on the imager and an adjustment amount set in a light amount adjustment unit in the imaging optical system and adjusts the light amount incident on the imager, and a determination unit configured to determine an exposure condition using the data acquired by the acquisition unit. The plurality of data includes first table data that provides a change amount of the light amount incident on the imager based on a change amount of the adjustment amount, and second table data that provides the change amount of the adjustment amount based on the change amount of the light amount incident on the imager.
