Abstract
Provided are a method and apparatus for adjusting brightness of an illumination device that is used in photographing an analysis object in a bio disk. The method includes taking images of an analysis object in a bio disk; calculating brightness of the images of the analyzing object; and adjusting brightness of an illumination device which is used in the photographing operation of the analysis object in the bio disk based on a difference between the calculated brightness and a target brightness.
Claims14
A method of adjusting brightness of an illumination device, the method comprising:
- taking images of an analysis object in a bio disk;
- calculating brightness of the images of the analysis object;
- and
- adjusting brightness of an illumination device which is used in the photographing operation of the analysis object in the bio disk based on a difference between the calculated brightness and a predetermined target brightness.
A bio disk drive comprising:
- a bio disk having a structure to analyze bio-materials;
- a camera module to take images of an analysis object in the bio disk;
- a controller to calculate brightness of the photographed images of the analysis object, and to generate an illumination control signal based on a difference between the calculated brightness and a predetermined target brightness;
- an illumination driver to generate an illumination driving signal based on the illumination control signal;
- and
- an illumination unit to generate light of an intensity which corresponds to the illumination driving signal.
