Abstract: An image sensor includes a first photodiode group, a second photodiode group, a first transfer transistor group, a second transfer transistor group, a floating diffusion region of a substrate in which electric charges generated in the first photodiode group are stored, and a power supply node for applying a power supply voltage to the second photodiode group. A barrier voltage is applied to at least one transfer transistor of the second transfer transistor group. The power supply voltage allows electric charges, generated in the second photodiode group, to migrate to the power supply node, and the barrier voltage forms a potential barrier between the second photodiode group and the floating diffusion region.

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.
