Charge coupled device for obtaining a 3-dimensional digital image

A charge coupled device for obtaining a three-dimensional image, the charge coupled device being installed in a digital image recording device to output an image of a subject, comprising:

• a main body, having an open top and a cavity formed therein, and having a chip pin formed on an outer surface thereof to transfer information to an electronic element of the digital image recording device;
• a light receiving element mounted on a bottom surface in an interior area of the main body and comprising a set of a plurality of optical sensors, which are sensitive to light;
• and
• a slit plate placed to cover an opening of the cavity of the main body, the slit plate having transparent parts and opaque parts arranged alternately in a pattern, and with widths of the transparent parts and the opaque parts in a uniform ratio,
• wherein a distance between the slit plate and the light receiving element is optimized such that an image information of the subject is recorded on the light receiving element at a location beyond a Fresnel region, in which light travels straight when light passed through a lens passes through the transparent parts of the slit plate, to obtain the image information of the subject with a three-dimensional information coupled thereto.
