FOCUS ADJUSTING DEVICE AND FOCUS ADJUSTING PROGRAM WITH DISTRIBUTION DETECTION OF FOCALIZED AND UNFOCUSED STATE |
摘要 |
A focus adjusting device which includes an edge detection unit that detects edges of a subject image for each color component forming an image including the subject image; a distribution detection unit that detects distributions of a focalized state and an unfocused state of the image based on the edges detected by the edge detection unit; and a control unit that moves a lens based on the distributions detected by the distribution detection unit, wherein the subject image is incident from an optical system having the lens, the control unit moves the lens, and thus the subject image is focused on. |

1. A focus adjusting device comprising:
an edge detection unit that detects an edge included in a subject from image data generated by an imaging unit that images the subject; a distribution detection unit that detects distributions of a focalized state and an unfocused state based on color component amounts of an edge detected by the edge detection unit; and a control unit which moves a lens, that guides a light image to the imaging unit, toward a direction so as to focus on an imaging surface of the imaging unit based on the distributions detected by the distribution detection unit. |
