Abstract: The present disclosure describes apparatuses and techniques for low-noise regulation of battery power. In some aspects an indication of a voltage level of a battery supplying power to a linear regulator is received, an output voltage level is determined for the linear regulator that permits the linear regulator to operate in an active condition in which noise of the power supplied by the battery is mitigated, and the linear regulator is configured to output the regulated power at the output voltage level effective to provide low-noise regulated power for components of a device.

Abstract: A method and system for scaling an original image into a scaled image is disclosed. Rather than using the corresponding position in the original image to generate the pixels values of a current pixel in the scaled image, image scalers in accordance with the present invention, calculate a high frequency adjusted position based on the high frequency components of pixels near the corresponding position. Pixel values based on the high frequency adjusted position provide better picture quality for the scaled image than pixel values based on the corresponding position. Furthermore, some embodiments of the present invention also use sharpness compensation to further improve the picture quality of the scaled image.
