The present invention provides automatic adjustments to an image presentation based upon changes in ambient light. The adjustments can be made to the back-lighting and / or the pixel data. The ambient lighting can be measured by a variety of sensors (e.g., a digital camera) from a variety of orientations. For example, the sensor can be directed away from the display (e.g., towards the user) or the sensor can be directed towards the display (e.g., from an angle comparable to the users view). In one exemplary implementation a graphics control system utilizes real time ambient light sampling input to calibrate a back-light illumination level and / or pixel illumination levels. The present invention can be implemented in a variety of devices (e.g., laptop, PDA, cell phone, headsup display, etc.).

Various embodiments of methods and systems for dynamically adjusting operating frequency settings of one or more processing components in a portable computing device (“PCD”) are disclosed. One such method involves receiving a request to adjust an operating frequency setting of a processing component to a required frequency (“F_req”) to process a workload. Factor readings associated with the operating capacity of the processing component may be taken. Based on the readings, performance curves associated with the processing component may be queried. The performance curves are used to determine the optimal operating frequency (“F_opt”) for the processing component. The F_opt is compared to the F_req and, if the F_req is less than F_opt, the operating frequency setting of the processing component is set to F_opt. Advantageously, as compared to F_req, at F_opt workload processing may be more efficient and a low power mode may be entered sooner.
