The present disclosure relates to an imaging device, a solid-state imaging element, a camera module, a drive control unit, and an imaging method for enabling reliable correction of an influence of a motion on an image. A state determination unit determines a state of a motion of an imaging unit that performs imaging to acquire an image via an optical system that collects light, and an exposure control unit performs at least control for an exposure time of the imaging unit according to a determination result by the state determination unit. Then, relative driving for the optical system or the imaging unit is performed to optically correct a blur appearing in the image according to an exposure period of one frame by the exposure time, and driving for resetting a relative positional relationship between the optical system and the imaging unit, the relative positional relationship being caused during the exposure period, is performed according to a non-exposure period in which exposure is not performed between the frames. The present technology can be applied to, for example, a stacked CMOS image sensor.

In a method of substantially correcting gradation values in a gradation correcting unit, the number of reproducible gradations is substantially reduced. Selection information of a boundary value table for multi-value error diffusion is stored, by ejection condition, in an information storing unit of a liquid ejecting head that can represent one pixel with a large number of liquid droplets. When the liquid ejecting head is mounted, selection information matching an ejection condition is read out and a boundary value table corresponding to the selection information is set for reference by a half toning unit. Consequently, the boundary value table is optimized to correct a gradation characteristic without substantially reducing the number of reproducible gradations.
