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.
Claims17
An imaging apparatus operable to generate image data based on an image of an object formed by means of a taking lens, and record the image data on a recording medium, the imaging apparatus comprising:
- a light source constituted by a semiconductor laser which emits a light;
- a Grating Light Valve which is supplied with a projection image signal and diffracts the light emitted from the light source with varying an intensity of the light based on the projection image signal which is used for projecting the image;
- and
- a scanning mirror which reflects the diffracted light toward the taking lens with having the diffracted light scan in a direction, so that the diffracted light forms the image of the object in front of the taking lens and by means of the taking lens.
