Abstract
A thin lightweight imaging device is provided. A highly convenient imaging device is provided. The imaging unit includes an imaging unit, a memory, and an arithmetic circuit. The imaging unit includes a light-receiving device, a first light-emitting device, and a second light-emitting device. The first light-emitting device has a function of emitting light in a wavelength range that is different from a wavelength range of light emitted by the second light-emitting device. The imaging unit has a function of making the first light-emitting device emit light and acquiring first image data. The imaging unit has a function of making the second light-emitting device emit light and acquiring second image data. The memory has a function of retaining the first reference data and the second reference data. The arithmetic circuit has a function of correcting the first image data with the use of the first reference data retained in the memory and calculating first correction image data. The arithmetic circuit has a function of correcting the second image data with the use of the second reference data retained in the memory and calculating second correction image data. The arithmetic circuit has a function of combining the first correction image data and the second correction image data to generate synthesized image data. The light-receiving device includes a first pixel electrode, and the first light-emitting device includes a second pixel electrode on the same plane as the first pixel electrode.
