Abstract: Some embodiments relate to sharpening segments of an image differently based on content in the image. Content based sharpening is performed by a content image processing circuit that receives luminance values of an image and a content map. The content map identifies categories of content in segments of the image. Based on one or more of the identified categories of content, the circuit determines a content factor associated with a pixel. The content factor may also be based on a texture and/or chroma values. A texture value indicates a likelihood of a category of content and is based on detected edges in the image. A chroma value indicates a likelihood of a category of content and is based on color information of the image. The circuit receives the content factor and applies it to a version of the luminance value of the pixel to generate a sharpened version of the luminance value.

Abstract: In an embodiment, a lifetime controller is configured to monitor operating conditions for a device, and to control operating conditions based on the previous conditions to improve the reliability characteristics of the device while permitting strenuous use as available. For example, the lifetime controller may permit strenuous use when the device is first powered on. Once a specified amount of strenuous use has occurred, the controller may cause the operating conditions to be reduced to reduce the wear on the device, and thus help to extend the lifetime of the device. Similarly, if a device is used in less strenuous conditions, the controller may accumulate credit which may be expended by permitting the device to operate in more strenuous conditions for a period of time.
