Claim:
1. An imaging device, comprising: a pixel; and a control circuit to apply a signal to the pixel, wherein the pixel comprises: a photodiode; a shift switching unit to be disposed at one side of the photodiode; a first storage node to be disposed at one side of the shift switching unit; a transfer switching unit to be disposed at one side of the first storage node; a second storage node to be disposed at one side of the transfer switching unit; and a reset switching unit to be disposed at one side of the second storage node, wherein the control circuit performs a first reading operation to read an amount of charges stored in the photodiode, a second reading operation to read an amount of charges overflowing into the first storage node from the photodiode and stored in the first storage node, and a third reading operation to read an amount of charges overflowing into the second storage node from the first storage node, wherein the first storage node comprise a gate configured to get a signal controlling potential barrier of the first storage node, wherein a first integration time, a second integration time and a third integration time are adjusted based on luminance of an obtained image, wherein each of the first integration time, the second integration time and the third integration time is used for integration of an amount of the charges to be read by each of the first reading operation, the second reading operation and the third reading operation.
