Image pickup unit and electronic apparatus

摘要

There is provided an image pickup unit capable of suppressing occurrence of false color and color mixture and acquiring a color image with high image quality. The image pickup unit includes: an image sensor including a plurality of pixels and acquiring an image pickup data; a variable filter provided on a light receiving face of the image sensor, and transmitting a selective wavelength; and a filter drive section (a wavelength selection circuit and a system control section) driving the variable filter and thereby setting its transmission wavelength. By acquiring the image pickup data while time-divisionally switching the transmission wavelength of the variable filter, pixel data corresponding to the transmission wavelength of the variable filter are acquired in a temporally-successive manner.
