Title:
3次元画像検出装置の焦点調節機構
Document Type and Number:
Japanese Patent JP4398562
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a three-dimensional image detector that can quickly detect three-dimensional image information being distance information of an object on the basis of two-dimensional image information being visual information of an object and an infrared ray in a focused state at all times. SOLUTION: Color separation filters F of a CCD employ a band filter having a spectrum transmissivity characteristics for narrow bands around each wavelength of red(R), green(G) and blue(B) and a band filter having a spectrum transmissivity characteristics for only an infrared ray band. Focus adjustment of a contrast system is applied to pixels provided with RGB color filters. After detecting two-dimensional image information, a lens drive circuit 27 drives a focal plane of an optical system by a necessary distance on the basis of data recorded in a memory 24. An infrared ray laser is emitted from a laser diode 14a and detects as three-dimensional image information.
