An imaging device includes a varifocal lens and an imaging sensor which outputs a signal corresponding to light. The imaging sensor includes a photoelectric conversion unit which converts light into an electric charge, electric charge reading regions, transfer control electrodes, a gate control circuit which sequentially applies control signals to the transfer control electrodes to correspond to the position of the focal point of the varifocal lens, and a reading circuit which outputs a signal corresponding to the amount of the electric charge transferred to the electric charge reading regions. The gate control circuit repeats an operation of outputting each of the control signals when the position of the focal point is located in the focal ranges during a frame period.

An apparatus includes a control unit that executes exposure control by adjusting a shutter speed, an aperture value, and a sensitivity, and a setting unit that switches on/off a simulation function for adjusting an image quality of an image for live view display to match an image quality depending on an aperture opening for acquiring a still image for recording. If the simulation function is on, the control unit controls a difference amount between an aperture value for acquiring the image for live view display and an aperture value for acquiring the still image depending on an aperture value for acquiring the still image for recording such that the difference amount when the aperture value for the still image is a second value larger than a first value is larger than that when the aperture value for the still image is the first value.

Disclosed are a method for determining semi-synchronous exposure parameters and an electronic device. The method in the embodiments of the present invention comprises: acquiring first exposure parameters corresponding to each lens; if it is determined that a preset EV limit value is not satisfied according to the first exposure parameters of each lens and adjacent lenses, respectively calculating exposure control parameters of each lens; calculating second exposure parameters corresponding to each lens according to the exposure control parameters of each lens and the first exposure parameters corresponding to each lens; if it is determined that the preset EV limit value is satisfied according to the second exposure parameters of each lens and adjacent lenses, determining the second exposure parameters corresponding to each lens to be semi-synchronized exposure parameters of each lens.

Visual focal point composition of media capture based on a target audience is provided. An aspect includes activating a profile selection function via a media recording device and receiving, via the profile selection function, an identifier of a target viewer of media content. The profile selection function provides a list of social network contacts, including the target viewer, via the media recording device. Another aspect includes retrieving contact preferences associated with the identifier. The contact preferences are determined from data about the target viewer that is sourced from one or more compartmentalized entities. The contact preferences identify focal aspects of media content statistically determined to be of interest by the target viewer. A further aspect includes providing suggested focal aspects of a scene subject to media capture. The suggested focal aspects are derived from the contact preferences.
