Imaging device, sensor, and imaging control device

A sensor comprising an imaging element that performs photoelectric conversion on incident light from a subject and generates an image signal, a plurality of pixels being arranged in a two-dimensional matrix in the imaging element,

• wherein one of a plurality of color filters that transmit beams of incident light of different wavelengths is arranged in each pixel block unit in which pixel blocks are arranged in two rows and two columns, the pixel blocks including four pixels arranged in two rows and two columns, and
• the sensor operates in one of a first imaging mode in which an image signal is generated for each pixel, a second imaging mode in which an image signal is generated for each pixel block, and a third imaging mode in which an image signal is generated for each pixel block unit.

An imaging control device that outputs, to a sensor, a control signal for switching between a first mode, a second mode, and a third mode based on a second image signal generated in one of the first mode, the second mode, and the third mode by the sensor including the first mode in which an image signal is generated for each pixel that performs photoelectric conversion on incident light from a subject, the second mode in which an image signal is generated for each pixel block including four pixels arranged in two rows and two columns, and the third mode in which an image signal is generated for each pixel block unit including four pixel blocks arranged in two rows and two columns.
