摘要： An optical disk player provided with tilt servo unit. A quadrant type photodetector is used as disk tilt detecting means, and the push-pull output is issued as a disk tilt detecting signal. By simultaneous use of the photodetector of the pickup, there is no need to use special-purpose tilt sensor, and this contributes to compact design of the pickup and to the reduction of manufacturing cost.

摘要： An image-generating system for generating data of an image on the basis of data of a photographic image obtained by capturing an image of an object. The image-generating system includes a color sample to be arranged in the proximity of an object, an illumination unit, an image pick-up unit, a color sample specifying unit and an image processing unit. The illumination unit can illuminate the object and the color sample with light lower in light quantity than ordinary light. The image pick-up unit obtains a photographic image by capturing an image of the object together with the color sample illuminated by the illumination unit. The color sample specifying unit specifies the color sample in the photographic image. The image processing unit converts colors of the object in the photographic image, taking the color sample specified by the color sample specifying unit as a reference.

摘要： An optical disk player using quadrant type photodetector as light receiving means. The phase difference output by the time difference detection method is issued as a tracking error, and a DC component of differential output by the push-pull method is issued as a tilt error, and zero cross of said differential output is detected. By using this detection output for the detection of zero-cross timing on off-track, stable operation of the tracking servo unit is ensured.

摘要： An optical disk player having a tracking servo apparatus and a focusing servo apparatus. By amplifying a focusing error at a predetermined gain and adding it to a tracking error, the rolling which occurs due to a mass balance distortion of a pickup is electrically suppressed. Thus, an adverse influence on the tracking servo by the rolling upon focusing driving can be prevented.

摘要： A recording disk reproducing apparatus employing simplified digital servo control for lower-cost, more stable operational control of the apparatus. At least one of a focusing servo loop, a tracking servo loop, a spindle servo loop, and a time base servo loop employs digital conversion of an analog error signal for processing in a microprocessor. The analog-to-digital conversion circuitry has an input-output characteristic which varies in accordance with error signal level, enabling a reduction in the number of bits of A/D output necessary, and reducing cost.
