    摘要： Embodiments of a system that includes one or more integrated circuits are described. During operation, the system transforms the video image from an initial brightness domain to a linear brightness domain, which includes a range of brightness values corresponding to substantially equidistant adjacent radiant-power values in a displayed video image. In this linear brightness domain, the system may determine an intensity setting of the light source based on at least a portion of the transformed video image, such as the portion of the transformed video image that includes spatially varying visual information in the video image. Moreover, the system may modify the transformed video image so that a product of the intensity setting and a transmittance associated with the modified video image approximately equals a product of a previous intensity setting and a transmittance associated with the video image. For example, the modification may include changing brightness values in the transformed video image.

    摘要： Embodiments of a system that includes one or more integrated circuits are described. During operation, the system receives a sequence of video images, where a given video image in the sequence, when displayed, includes a picture portion and the non-picture portion, and where the picture portion has a histogram of brightness values. Then, the system determines the intensity setting of the light source on an image-by-image basis based on the histogram, where the light source is configured to illuminate a display that is configured to display the sequence of video images. Next, the system selectively filters changes in the intensity setting of the light source, where the selective filtering is based on a magnitude of a given change in the intensity setting from a previous video image to a current video image.

    摘要： A magnetic data storage medium includes a dedicated transducing head contact zone for engaging an air bearing slider, primarily when the disk is stationary. The contact zone is textured with an irregular sequence of spaced apart nodules forming a substantially circumferential, spiral path. The spiral path includes multiple terms that define a uniform radial pitch. The circumferential pitch is irregular, more preferably determined according to pseudo-random function in which the actual spacing intervals vary about a nominal interval, over a range comparable to, but generally less than, the interval. The pseudo-random array can be formed by a texturing process that includes directing a focused laser beam onto the contact zone. The disk is rotated to maintain a constant circumferential speed relative to the laser, and also is translated radially to provide the desired radial pitch. The laser is operated in a continuous wave mode, with an acousto-optic modulator between the laser and disk operated to provide a pseudo-random variance in time intervals between successive laser exposures.

    摘要： A magnetic data storage medium includes a dedicated transducing head contact zone for engaging an air bearing slider, primarily when the disk is stationary and also during disk accelerations and decelerations. The contact zone has a dual baseline texture, formed by first creating a recessed region within the transducing head contact zone, and then by forming multiple nodules or other texturing features within the recessed region. The texturing features project upwardly from a recessed surface of the recessed region, and also project above an upper surface of the disk by an amount less than the texturing feature height. Consequently, the texturing features are large enough to counteract stiction due to liquid lubricant meniscus formation, yet also have heights sufficiently low relative to the upper surface to allow reduced transducer flying heights. According to a preferred texturing process, the recessed region consists of multiple individual recesses produced by applying a carbon layer to the disk, then forming cavities by selective laser ablation of the carbon layer.

    摘要： Embodiments of a system that includes one or more integrated circuits are described. During operation, the system receives a sequence of video images, and calculates brightness metrics associated with the video images in the sequence of video images. Then, the system determines an intensity setting of a light source, which illuminates a display that is configured to display the sequence of video images, and scales brightness values of a given video image in the sequence of video images based on a given brightness metric associated with the given video image. Next, the system changes the intensity setting and scaling the brightness values when there is a discontinuity in the brightness metrics between two adjacent video images in the sequence of video images.
