An image sensor is provided to effectively increase dynamic range of an image sensor by connecting a switching transistor and a storage capacitor between a floating diffusion terminal and a reset transistor. An image sensor comprises a photodiode, a reset transistor(240), a drive transistor(250), and a selection transistor(260), and includes a switching transistor(S1)(280) and a storage capacitor(SC)(290). The switching transistor is formed between the photodiode and the reset transistor. The storage capacitor is formed in one side of the switching transistor. A transfer transistor(220) and a floating diffusion region(FD) are formed between the photodiode and the reset transistor. The switching transistor is formed between the floating diffusion region and the reset transistor.
