    摘要: A pixel is driven with pulse width modulation (PWM). A cycle for the PWM signal is divided into a plurality of super-intervals. Each of the super-intervals is divided into a plurality of intervals. An interval index is stored for the pixel. The timing at which the pixel is changed from one state to another is selected based on an enable signal and the stored interval index.

    摘要: In an embodiment of the invention, a method of downscaling an original image by generating a number of pixels comprising first, second, and third sets. Each pixel comprises a number of components. The method operates by determining all of the components in each pixel of the first set, determining some of the components in each pixel of the second set, and pixels in the third set having no components determined. The scaled image is thus partially determined, with the second and third sets having missing components. The missing components may then be determined by conventional interpolation. Mathematical operators are applied to regions of the image to yield the first, second and third sets of pixels that define the scaled image, without generating an intermediate image in which all three components are determined. The operators may combine interpolation and low pass filtering using a Hamming filter. In certain system applications such as the digital camera, components in the first set and the second set are determined by the digital camera and then transferred to a data processing system (e.g. a personal computer) before the missing components of the second and third sets are determined.

    摘要: A methodology for white balancing a digital color image in its entirety without segmenting the image into sections. In one embodiment, the images (still or video) are captured and transferred to a computer, and software loaded in the computer then performs the white balancing methodology. A global white point is generated for a color image based on pixels of the image that are in a given percentile of frequency distribution, such as one that is part of a histogram. Pixel adjusting values are then computed for the image and used to white balance the entire image indiscriminately to improve its color quality.

    摘要: A spatial light modulator may be adapted to receive bi-directional drive signals. The spatial light modulator may include a plurality of pixel elements having individual first electrodes and a common electrode providing a second electrode for each of the pixel elements. The pixel elements may be adapted to change between a first state and a second state in accordance with signals applied thereto, and the bi-directional drive signals may include at least a first drive signal and a second drive signal. Both drive signals are applied to change the pixel elements from the first state to the second state and from the second state to the first state.

    摘要: An apparatus and method for protecting a content item such as a digitally encoded movie, an electronic programming guide, or the like, by reordering blocks of the content item prior to transmitting it to a receiving device. The receiving device constructs a block reordering structure which is used to access the reordered content item, to facilitate retrieval of a desired block from the original content item. The reordering may be done responsive to an identifier value of the receiving device, such as a serial number.

    摘要: A programming guide for streaming video files may be automatically compiled in response to a user request. The user may provide keywords for categories of streaming video files that are of interest. A graphical user interface is automatically developed which splits responsive streaming video files into categories requested by the user. Each streaming video file may be represented in a user selected fashion. For example, the streaming videos may be represented by a representative frame, title or other information. The user can then click on any of the streaming video files, broken down into the appropriate categories, to begin viewing a streaming video file of interest.
