摘要： A technique increases the number of colors output by an active color display by providing an increased number of grey levels for each pixel component. An M×N matrix pattern of pixel components is generated having a ratio of pixel components at a particular color level to pixel components at a different color level to achieve a particular grey level, where M and N are greater or equal to two. The M×N matrix pattern is repeated for X frames, and at least one pixel component is at the particular color level in each frame. At the end of the Nth frame, the matrix pattern from frame zero is repeated.

摘要： A technique to increase the number of colors output by a passive color LCD display provides an increased number of grey levels for each pixel component. An M×N matrix pattern of pixel components is generated having a ratio of pixel components that are ON to the total number of pixel components to achieve a particular grey level on the passive color LCD screen, where M and N are greater or equal to two. The M×N matrix pattern is repeated for X frames, and at least one pixel component is ON in each frame. At the end of the Xth frame, the first matrix pattern for frame zero is repeated.

摘要： An integrated circuit includes a core-logic providing a core-logic output, a latch in communication with the core-logic to store a state of the core-logic output, and an isolation circuit for selectively interconnecting the core-logic output to an input of the latch. The circuit also includes and a power consumption controller in communication with the core-logic, the latch and the isolation circuit, for controlling the latch to store a state of the core-logic output, and output a corresponding signal. The controller is further operable to signal the isolation circuit to isolate the core-logic output from the latch by providing an output corresponding to predetermined value and transition the core-logic from a high power state and a low power state. This prevents transient signals from propagating to interconnected circuit blocks and external devices.

摘要： To provide reduced power consumption of a co-processor, a low power dedicated memory is provided. During a low power state, a processing component of the co-processor is instructed to use the low power dedicated memory and a first memory device, normally used by the processing component, is thereafter operated in a reduced power mode for the duration of the low power state. Preferably, the low power dedicated memory has a storage capacity that is significantly less than the storage capacity of the first memory. When an operating state other than the low power state is detected, normal power consumption by the first memory is resumed and the co-processor is directed to use the first memory once again. In this manner, the present invention allows co-processors, and preferably graphics co-processors, to operate in a beneficial low power mode thereby reducing power consumption.

摘要： A system and method are provided for reducing power consumption within a video processing portion of a system based on display content. Display content is monitored to determine whether the display content is changing. New display content is compared to old display content to determine if the display content is changing. If the display content has not changed, a frame rate used to output display data is reduced. A color depth associated with the display data is also reduced. Power consumption can be reduced when it is determined that display content is not changing.

摘要： A method of enhancing photographic images of low optical density is disclosed which includes use of a luminescent system, the components of which system include, at least, photoluminescent material and a source of photons for exciting the same to luminescence. A photoluminescent replica of the low optical density photographic image is produced which replica is exposed to photons required for luminescence of the photoluminescent image replica which luminescence is recorded, or photographed, for an amount of time necessary to achieve enhancement of the photographic film image. The image enhancement method may be used for the enhancement of photographic images produced by photographic processes including, for example, those which involve the use of different radiant energy sensitive material such as silver halide as used in `conventional` photography, photoconductive material as used in electrophotography, organic compounds as used in diazo photographic processes, and the like.

摘要： A transform function represented by at least n points that define n-1 regions is determined based at least in part on a first set of values associated with a display frame and a maximum average contrast function. The n points can be determined in response to a change in an average contrast of the display frame compared to an average contrast of a previous display frame exceeding a predetermined threshold. The first set of values is converted to a corresponding second set of values based on the transform function. A backlight control signal is generated based on an average contrast of the second set of values, whereby the backlight control signal is configured to control an intensity of a backlight of a display. Further, a video signal is generated based on the second set of values, whereby the video signal configured to drive the display.

摘要： An n bit D/A decoder is formed using P-type and N-type transistor switches, instead of convention CMOS switches. Each P-type and N-type switch may be formed of fewer transistors than those used to form a CMOS switch, thereby reducing the overall transistor count. The decoder may be used to decode digital values to non-linear GAMMA corrected analog output voltages.

摘要： An apparatus and method of treating multiple wafers to reduce the density of impurities as well as to improve the uniformity of substrate electrical characteristics without any thermal stress. The wafers are chemically treated, and heat treated in a sealed reaction tube under arsenic overpressure with a controlled thermal profile to heat the wafers. The thermal profile controls temperature of different zones inside of a furnace containing the sealed reaction tube. Impurities of the wafers are dissolved, and are out-diffused from the inner portions to the outer portions of the wafers.

摘要： A method comprises disabling a video digital-to-analog converter (DAC) that is configured to provide an output current representative of a video signal to an output node of an accessory connector in an enabled state. The accessory connector is coupleable to an accessory device. The method further comprises determining, while the video DAC is disabled, whether the accessory connector is coupled to the accessory device based on a voltage at the output node while the output node is connected to the first voltage reference via a resistor having a resistance.
