摘要： In an optical recording device in which the writing laser light beam is focused to a small spot on a disk which is coated with a photosensitive medium and spins at a predetermined velocity so that the data are recorded in terms of variable density or surface irregularities, the forward DC current applied to a semiconductor laser is varied depending upon the radius position of the writing laser beam spot on the disk but the AC current which is superposed on the DC current and rises or drops above or below the DC current level by a predetermined amplitude depending upon the data to be recorded is maintained constant regardless of the radius position of the writing laser beam spot, whereby the duty ratio can be maintained constant regardless of the distance from the center of the disk of a selected recording track.

摘要： A servo control system includes an error amplifier for deriving an error signal representing the displacement of a focus point of laser beam from different planes of an optical record disc, a differentiator for differentiating the error signal to detect its rate of variation, and a comparator for detecting the maximum peak of the differentiated signal which corresponds to reflections from the plane on which information is recorded. The focus point is moved in a direction toward the disc in an open loop mode until the maximum peak of the differentiated signal is detected, whereupon the focus point is controlled in response to the error signal in a closed loop mode to keep track of the recording plane.

摘要： An optical reproducing device for reproducing still image signals recorded on circular tracks and moving image or audio signals recorded on spiral tracks on a disk. Concentric and spiral tracks may be intermingled on the same disk. The address signals for each concentric track or each coil of a spiral track are previously recorded. When the address signals are reproduced, they are processed so as to detect whether the readout address signals changes with time, thereby detecting whether the accessed track is concentric or spiral. An optical head drive system is controlled in a manner depending on whether the track is circular or spiral, so that an optical head can scan the desired concentric or spiral track.

摘要： A plurality of lenses 102a to 102d arranged in the same plane form a plurality of subject images on a plurality of imaging regions 104a to 104d. Vertical line directions and horizontal line directions of the pixel arrangement in the respective plurality of imaging regions are equal to one another among the plurality of imaging regions. Further, at least one pair of subject images received by at least one pair of imaging regions having a parallax in the vertical line (or horizontal line) direction among the plurality of imaging regions are shifted from each other by a predetermined amount in the horizontal line (or vertical line) direction. By performing pixel shifting in a direction perpendicular to the direction in which a parallax is generated, it always is possible to obtain a high-resolution image even when the subject distance varies.

摘要： In a method for forming an image of a subject on a solid-state imaging device, a first time period for splitting a light beam from a subject into a plurality of light beams that have different polarization directions and then combining the plurality of light beams to form a single subject image on the solid-state imaging device and a second time period for splitting the light beam from the subject into the plurality of light beams that have different polarization directions and forming a plurality of subject images that overlap each other partially on the solid-state imaging device are switched time-wise. A first image information on the single subject image is obtained based on pieces of signal information in the first time period, and a second image information on one of the plurality of subject images is calculated by using and computing pieces of signal information in the second time period. Then, the high-resolution image of the subject is achieved by using the first image information and the second image information. In this way, it is possible to obtain an image with a high resolution and a reduced noise with substantially no loss of the light beam from the subject.
