Classification: CPC H | IPC H

Claim 6:
7. An imaging device comprising:
an image sensing device including a plurality of pixels structured to detect incident light to generate a pixel signal corresponding to an intensity of the incident light and generate image data corresponding to the pixel 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 high dynamic range (HDR) controller configured to generate a control signal by calculating a set value for at least one of an amount of light exposure, an exposure time, a conversion gain, and an analog gain, as a controllable item, based on the image data;
an image signal processor coupled to receive the control signal from the high dynamic range (HDR) controller and configured to synthesize image data having different sensitivities generated by adjusting the sensitivity of each of the plurality of pixels in response to the received control signal and generate a high dynamic range (HDR) image based on the image data,
wherein the amount of light exposure is controlled by adjusting the degree of opening or closing of the aperture; and
a row driver configured to generate a transfer signal for transmitting photocharges generated in each of the plurality of pixels in response to the intensity of incident light to a floating diffusion region,
wherein the exposure time is controlled by adjusting a time period during which the transfer signal has a predetermined level.
