摘要： An object of this invention is to enable performing accurate DC recovery operation for an output signal from an image sensing element, and obtaining a high-quality image free from any image degradation such as a horizontal streak. To achieve this object, an image sensing apparatus includes first and second clamping circuits on the output side of an image sensing element. The image sensing element outputs a signal from an effective pixel region, a first reference signal for DC recovery of an image signal that is set for each row, and a second reference signal that is uniformly set for the pixel region. The first clamping circuit DC-recovers a signal from the effective pixel region for each row on the basis of the first reference signal. The second clamping circuit uniformly DC-recovers signals from the effective pixel region for the pixel region on the basis of the second reference signal. The first reference signal is a signal obtained in a horizontal reference region free from any influence of an output from the photodiode of the image sensing element. The second reference signal is a signal which is obtained in a vertical optical black region and contains a dark current component generated in the photodiode of the image sensing element.

摘要： Disclosed is an optical disc apparatus that sets a plurality of virtual zones, which correspond to a plurality of zones that are arranged in the radial direction of an optical disc, for a plurality of recording layers of the optical disc. When a servo signal distortion is detected in a virtual zone to change the rotation speed of the optical disc to a low speed in the virtual zone during an information recording or reproduction operation relative to a first recording layer, the optical disc apparatus stores the change information. When a recording or reproducing operation is to be performed in a virtual zone of a second recording layer, which is in the same disc radial position as the virtual zone of the first layer, the optical disc apparatus changes the rotation speed of the optical disc for the virtual zone to a low speed in accordance with the change information.

摘要： An optical disc apparatus, as a learning operation before a recording or reproducing operation, rotates an optical disc at a first speed to read PID information, discriminates between lands and grooves of the optical disc, detects switching positions between lands and grooves, sets a rotation angle position of tracking pull-in of an objective lens of a time length that allows the PID information to be stably read, with respect to the switching position, and stores the set position information of tracking pull-in as learning result information. During recording or reproducing, the optical disc apparatus rotates the optical disk at a second speed higher than the first speed, pulls in the objective lens for tracking based on the stored position information of tracking pull-in, reads PID information, and performs the recording or reproducing operation while discriminating between lands and grooves and detecting switching positions between lands and grooves.

摘要： In a display device the possibility that the ratio between a display period for display signals and a display period for blanking signals differs from a preset ratio is eliminated, even when the video data is changed. A display device sequentially supplies blanking data from a data driver circuit which sequentially supplies display signals after a lapse of a given time from starting the supply of the display signals. In the display device, a ratio of display is set based on the blanking data per one frame period. Further, the number of pulses of a horizontal synchronizing signal is measured in one frame period contained in the video data, and a point of time is determined for starting display based on the blanking data in response to pulses of the horizontal synchronizing signal corresponding to the ratio based on a measured value of the number of pulses.
