Patent ID: 8513760

Claim:
An image sensor comprising: a plurality of unit pixels, wherein each unit pixel comprises a photo diode for sensing external light to generate photo charges; a transfer transistor connected to the photo diode, wherein the transfer transistor is configured to store the photo charges generated in the photo diode into a floating diffusion region when being turned-on; an amplification transistor, wherein the amplification transistor is configured to amplify the photo charges stored into the floating diffusion region; a select transistor connected to the amplification transistor, wherein the select transistor is configured to perform a switching operation; and an output line extending in a column direction, wherein the output line is configured to output the photo charges in accordance with the switching operation of the select transistor, wherein the photo diode is arranged to share the output line with an adjacent photo diode in a horizontal a direction, so that the photo charges generated in the photo diode and the adjacent photo diode are outputted through the output line.
