摘要： In an imaging device having an all-pixel read mode for reading signals from all pixels and a pixel downsampling read mode for reading signals by appropriately discarding pixels, adjacent ones of pixels use a floating diffusion capacitance, an amplifying transistor, a reset switch and a selection switch in common. In the pixel downsampling read mode, not only a primary capacitance but also a photodiode in each pixel to be discarded are used as capacitances for storing signal charges transferred from transfer switches. This makes it possible to lower the gate voltage of the amplifying transistor as compared with the case of using only the primary capacitance as a capacitance for storing signal charges transferred from a transfer switch to reduce the sensitivity of the pixels, thereby reducing the occurrence of flicker.
