摘要： A photographing apparatus, comprising: an imaging optical system; an image sensor which receives a light flux passing through the imaging optical system, captures an image, and outputs an imaging signal; an aperture which is included in the imaging optical system and which includes an opening to restrict the light flux; a controller which performs a first exposure control to control the exposure of the image sensor by changing the opening of the aperture and calculates, based on an imaging signal output by the image sensor, a deviation between an optimal exposure amount and a currently set actual exposure amount; and an imaging control circuit which performs a second exposure control to control the exposure of the image sensor without changing the opening of the aperture, wherein the controller selects either the first exposure control or the second exposure control based on the deviation to control exposure.

摘要： When a exposure controlling unit changes an aperture value of a diaphragm in a predetermined range, the exposure controlling unit also changes a transmittance of a variable ND filter so as to perform an exposure control and, after obtaining a proper exposure by changing both the aperture value and the transmittance, sets the aperture value after exposure control to Fa, and in a case where the aperture value at which a maximum resolving power is obtained is set to Fb, when a condition, Fa≠Fb, is satisfied and the transmittance is neither the minimum nor the maximum, the exposure controlling unit brings the aperture value close to Fb and changes the transmittance so as to maintain the proper exposure after the exposure control.

摘要： An illumination apparatus which is capable of appropriately determining whether or not a radiating direction of a flash is deviated from a direction targeted by a user and preventing degradation in user convenience. The illumination apparatus has a movable unit that has a light-emitting unit, and a main body unit that holds the movable unit rotatably in a predetermined direction. A present angle of the movable unit with respect to the main body unit is detected, and a difference between the present angle and a target angle to which the movable unit is to be moved is obtained. When the difference is smaller than a threshold value, it is determined that there is no angular deviation of the movable unit. The threshold value used in the determination varies with the target angle.

摘要： A camera is provided which includes a backlight judgment section which determines whether the photographic scene is backlit by comparing the average luminance of the entire photographic screen obtained by photometry with the luminance of the main subject at a distance-measuring point selected by distance measurement. The camera performs suitable exposure control accompanied by illumination, such as supplementary light, at the time of exposure in a photographic scene where the main subject is against light.
