Imaging device and solid-state imaging device

The imaging device (200) according to the present invention comprises a solid-state imaging device (201) that has a plurality of pixels (204) arranged in a two-dimensional manner, and a signal processing device (202) that processes signals output from the solid-state imaging device (201), wherein: a correction signal is generated based on the difference between a first preliminary correction signal, which is obtained by directly applying a first voltage amplitude to a signal retention part within a pixel (204), and a second preliminary correction signal, which is obtained by applying a second voltage amplitude different from the first voltage amplitude to the signal retention part; the solid-state imaging device (201) captures an image, thereby obtaining an image signal; and the correction signal is applied to the obtained image signal so as to generate a corrected image.
