Abstract
An image sensor includes a pixel array, an analog-to-digital conversion circuit, and an image signal processor. A pixel of the pixel array generates a first analog signal based on a quantity of charge accumulated during a first exposure time and generate a second analog signal based on a quantity of charge accumulated during a shorter second exposure time. The analog-to-digital conversion circuit may generate a first digital signal based on the first analog signal and a first ramp signal and may generate a second digital signal based on the second analog signal and a second ramp signal. The image signal processor may generate image data based on the first and second digital signals. The first ramp signal may be different from the second ramp signal in terms of at least one of a ramping time or a ramping start voltage level.
