Title: Optical pickup device
Inventor: SUGIYAMA TOSHIO
IPC: G11B7/12
Filed: 1982-04-07
Abstract: PURPOSE:To reduce the optical noise without the influence of the retardation of a disc, by feeding back a specific quantity of light to a semiconductor laser, especially, single longitudinal mode laser. CONSTITUTION:The luminous flux of a semiconductor laser 1 is converted to a parallel luminous flux by a coupling lens 2 and is condensed onto a signal face of a disc 5 through a half prism 3 and a condenser lens 4. The reflected light is reflected by the half prism 3 and is converted to an electric signal by a photodetector 6. A part of the reflected light is returned to the semiconductor laser 1. For the purpose of reducing the variance of the quantity of reflected light due to the influence of the retardation of the disc 5, a polarizing prism and a 1/4 wavelength plate are not used, and consequently, not a circularly polarized light but a linearly polarized light is made incident to the disc 5, and the quantity of feedback light is 1-10% for 100% quantity of emitted light of the laser for the purpose of reducing the noise of the quantity of feedback light due to the quantity of light return of the laser.

Abstract: PROBLEM TO BE SOLVED: To easily and speedily obtain a depth information of high precision and high utilization value from an optional point of view by allowing a depth information extracting means to extract depth information of each part of a subject by a prescribed processing using a curvilinear coordinate. SOLUTION: A picture processing part 220 connecting the video signal of the subject separating only a back face area to subject separation parts 105L and 105R extract-processes depth information based on a parameter at the time of photographing. On the other hand the picture processing part 220 executes the extracting processing of depth information using parallax with respect to a video signal consisting of a luminance signal and a chrominance signal obtained by video signal processing parts 104L and 104R. At this time each depth information divides outer voxcel data by many line segments to set voxcel data outside of these line segments to be not a subject part and integrates the entire subject by only inside by a system controller 21 to obtain final depth information. Consequently depth information of high utilization value is obtained at a high speed.

The reverse energizing time depends on the result of range-finding, and it is different between a telephoto side and a wide angle side and is set at every zoom zone. As to the reverse energizing time, the brake time is set in accordance with the moving speed of the focusing lens so as to perform the stop control corresponding to the speed to stop the lens with the constant over run at any time. Furthermore, the focusing lens is stopped in a short time with high accuracy.
