Abstract

An imaging system for generating a high dynamic range (HDR) image includes: a pixel array including a first pixel and a second pixel; a driver circuit configured to control the first pixel based on a first exposure time and control the first pixel based on a second exposure time a second pixel time; an output circuit configured to output a first pixel value of the first pixel and a second pixel value of the second pixel from the pixel array; and a processing device configured to be based on the first Bayer image and the second Bayer image An HDR image is generated, wherein the first Bayer image is generated based on the first pixel values, and the second Bayer image is generated based on the second pixel values ​​and the third pixel values ​​of the first Bayer image. The number of pixels of the first pixel may be greater than the number of pixels of the second pixel.
