Abstract
An imaging apparatus having a projector function which is advantageous in reducing size is provided. A light source of the imaging apparatus is constituted by three semiconductor lasers which respectively frontward emit lights of red, green and blue, each slit-shaped. To a GLV (Grating Light Valve) is applied a drive voltage as modulated by a projection image signal, so that the GLV diffracts the three lights emitted from the light source, with varying the amount or intensity of each light in accordance with the drive voltage or projection image signal. A scanning mirror is disposed between a taking lens and an image pickup device, so as to reflect the lights diffracted by the GLV toward the taking lens, with having each diffracted slit-shaped light scan in a direction.
