OG exemplary drawing
1. An image sensor, comprising:
a pixel array including a plurality of pixels; and
a logic circuit configured to obtain a pixel signal from the pixel array,
wherein each of the plurality of pixels comprises:
a first photodiode;
a second photodiode;
a floating diffusion node configured to accumulate electric charges generated from the first photodiode and the second photodiode and directly connected to a gate node of a first transistor;
a second transistor connected to the first photodiode;
a third transistor and a fourth transistor that are serially connected between the floating diffusion node and the second photodiode;
a fifth transistor connected between the floating diffusion node and a power node; and
as sixth transistor configured to be connected between the power node and the second photodiode.
