摘要： An imaging apparatus, comprising a lens unit having a photographing optical system, and a body having an image sensor for generating a pixel signal by imaging subject light that has passed through the photographing optical system, comprising an exposure control section for adjusting exposure amount for image data based on a pixel signal generated by the image sensor, by transmitting an aperture control signal to the aperture control section and changing opening of the aperture, and a determination section for determining whether or not the aperture control section is able to control opening of the aperture based on information from the lens unit, wherein the exposure control section does not transmit aperture control signals to the aperture control section when it is determined by the determination section that the aperture control section is able to control opening of the aperture.

摘要： An imaging device includes an imaging section, a main subject detecting section, a main subject color determining section, a background color setting section, an exposure control section, and a photography control section. The imaging section images a subject. The main subject detecting section detects a region of a main subject in image data. The main subject color determining section determines a color of the region of the main subject. The background color setting section sets a color of a region that becomes a background of the region of the main subject. The exposure control section sets an exposure setting value in accordance with the color of the region that becomes the background. The photography control section controls main imaging in accordance with the exposure setting value.

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.
