摘要： Software-assistance that allows a child or other author to generate a story. The author may generate their own content and add that author-generated content to the story. For instance, the author could drawn their own background, background items, and/or characters. These drawn items could even be added to a library so that they could be reused in other stories. The author can define their own animations associated with characters and background items, rather than selecting predefined animations. The story timeline may also keep track of events that are caused by the author interacting with the story in particular ways, and that represents significant story changes. The author may then jump to these navigation points to delete the event thereby removing the effects of the story change.

摘要： A system and method corrects luminance non-uniformity and increases the apparent amplitude resolution of an image generated by a projector. The projector, which has a given number of stated levels, receives input data and projects images based on that input data. To correct luminance non-uniformity, a projector correction look-up table (LUT) is created. The LUT attenuates the displayed image such that the whole image has the same luminance as the dimmest point. Input data received by the projector is modified by correction information containing in the LUT. The projector output is analyzed to identified the number of unique levels that the projector is capable of producing, which may be less than the number of stated levels. A dithering engine modify the corrected image data to increase the projector's amplitude resolution, creating the illusion of the projector having more than the limited number of unique levels identified.

摘要： The present disclosure describes methods and devices for generating a vector line drawing. A vector line drawing network may include a machine learning-based model that is trained to convert a raster image to a vector line drawing directly. The vector line drawing network may be trained end-to-end, using supervised learning, where only raster images are used as training data. A vector line drawing is generated stroke by stroke, over a series of time steps. In each time step, a dynamic drawing window is moved and scaled across the input raster image to sample a patch of the raster image, and a drawing stroke is predicted to draw a stroke in a corresponding patch in the canvas for the vector line drawing. The image patches are pasted in the canvas to assemble a final vector line drawing that corresponds to the input raster image.

The projector, which has a given number of stated levels, receives input data and projects images based on that input data. To correct luminance non-uniformity, a projector correction look-up table (LUT) is created. The LUT attenuates the displayed image such that the whole image, assuming it has a uniform level, has the same luminance as the dimmest point. Input data received by the projector is modified by the correction information contained in the LUT. In addition, the output of the projector is analyzed to identify the number of unique levels that the projector is capable of producing, which may be less than the number of stated levels. A dithering engine is utilized to further modify the corrected image data to increase the projector's amplitude resolution, thereby creating the illusion that the projector has more than the limited number of unique levels that were identified.

摘要： A fractional-N PLL uses separate charge pumps under the control of separate frequency and phase detectors. Phase jitter from an N divider is linearized by the use of a circuit that generates pulses from the output of the N divider. After frequency lock, the frequency detector turns off the frequency charge pump. After phase lock, activity in the phase detector down charge pump is minimized, reducing the overall noise produced by respective phase and frequency detector charge pumps.
