Abstract
A mobile device including: at least an imaging element; and a light-emitting device that irradiates a subject in accordance with imaging of the imaging element, in which the light-emitting device includes a semiconductor light-emitting element, and the difference of the normalized spectral power distribution at a wavelength of 580 nm and a value B representing a difference between normalized spectral power distributions in a wavelength range from 540 nm to 610 nm and a wavelength range from 610 nm to 680 nm are appropriate values. By providing a wavelength control element, it is possible to improve the color reproducibility and the like of a captured image. The mobile device achieves both sensitivity improvement and color reproducibility in a trade-off relationship.
