摘要： An image sensing device includes a plurality of image sensor pixels including a first image sensor pixel and a second image sensor pixel and a transmission driver. The transmission driver is coupled to first and second transfer gates to apply a first transmission signal to the first transfer gate to control the first transfer gate and a second transmission signal to the second transfer gate to control the second transfer gate. A first distance between the first image sensor pixel and the transmission driver is shorter than a second distance between the second image sensor pixel and the transmission driver, and the first and second transfer gates of the first image sensor pixel are different in structure from the first and second transfer gates of the second image sensor pixel, respectively.

摘要： An image sensor includes a detection region, a first transistor region, and a second transistor region. The detection region including a first demodulation node and a second demodulation node generates a hole current in a substrate, and captures photocharges that are generated by incident light and move by the hole current. The first pixel transistor region including a plurality of transistors is disposed at one side of the detection region, and processes photocharges captured by the first demodulation node. The second pixel transistor region including a plurality of transistors is disposed at other side of the detection region, and processes photocharges captured by the second demodulation node.
