A camera main body includes a mount, a solid-state imaging element, a main body controller, a card I/F, an accessory information storage section, a rear surface display section, and a finder section. An interchangeable lens is attached to the mount. A setting menu is displayed on the rear surface display section. The main body controller extracts accessory information including an imaging time point in a specific time slot from a plurality of pieces of accessory information read out from a memory card by the card I/F. Further, the main body controller changes a setting menu in accordance with imaging conditions included in accessory information that is extracted as the accessory information including the imaging time point in the specific time slot and is stored in the accessory information storage section.

A method includes detecting, based on sensor data from a sensor on a mobile device, an environmental brightness measurement, where the mobile device comprises a display screen configured to adjust display brightness based on environmental brightness. The method further includes determining, based on image data from a camera on the mobile device, an extent to which the detected environmental brightness measurement is caused by reflected light from the display screen. The method additionally includes setting a rate of exposure change for the camera based on the determined extent to which the detected environmental brightness measurement is caused by reflected light from the display screen.

The present technology relates to a light receiving device, a control method, and an electronic apparatus capable of suppressing saturation of a sensor that receives light. A control unit performs exposure control to control, in accordance with a photometry result of a photometry sensor that performs photometry by receiving light, exposure of another sensor of which a light receiving surface that receives light is divided into a plurality of blocks, the exposure control being performed for each block. The present technology can be applied, for example, an electronic apparatus such as a digital camera that receives light.
