1. An imaging device comprising:
an image sensing device including a plurality of pixels, each of which is structured to detect incident light from a scene to generate a pixel signal corresponding to an intensity of the incident light and generate image data corresponding to the pixel signal, wherein the image sensing device operates to perform imaging operation in response to a control signal;
an aperture driver configured to adjust a degree of opening or closing of an aperture disposed in front of the image sensing device;
a luminance acquisition unit configured to acquire the image data corresponding to first pixels among the plurality of pixels associated with a target region of an image of the scene captured by the image sensing device;
a controllable item acquisition unit configured to acquire one or more sensitivity items indicative of sensitivity of each pixel to light, as a controllable item; and
a set value calculation unit configured to generate the control signal to the image sensing device by calculating a set value for the controllable item based on the image data of the target region and the controllable item,
wherein:
the one or more sensitivity items include at least one of an amount of light exposure, light transmittance, an exposure time, a conversion gain, and an analog gain; and
the amount of light exposure is controlled by adjusting the degree of opening or closing of the aperture.
