PHOTOGRAPHING DEVICE AND PHOTOGRAPHING METHOD FOR TAKING PICTURE BY USING A PLURALITY OF MICROLENSES
First Claim
1. A photographing device comprising:
- a main lens configured to transmit light beams reflected from a subject;
a microlens array which comprises a plurality of microlenses configured to filter and transmit the reflected light beams as different colors;
an image sensor configured to sense the light beams that are transmitted by the plurality of microlenses to sense a plurality of original images;
a data processor configured to collect pixels of positions corresponding to one another from the plurality of original images sensed by the image sensor to generate a plurality of sub images;
a storage device configured to store the plurality of sub images; and
a controller configured to detect pixels matching one another in the plurality of sub images stored in the storage device, and acquire color information and depth information of an image of the subject based on a result of the detection.

Abstract
A photographing apparatus and method are provided. The photographing device includes: a main lens configured to transmit light beams reflected from a subject; a microlens array which includes a plurality of microlenses configured to filter and transmit the reflected light beams as different colors; an image sensor configured to sense the light beams that are transmitted by the plurality of microlenses; a data processor configured to collect pixels of positions corresponding to one another from a plurality of original images sensed by the image sensor to generate a plurality of sub images; a storage device configured to store the plurality of sub images; and a controller configured to detect pixels matching one another in the plurality of sub images stored in the storage device and to acquire color information and depth information of an image of the subject. Therefore, color information and depth information are restored without reducing resolution.
