Overview
Digital cameras provide a means for capturing still pictures as well as limited video capture. Similar to mobile smartphones, battery life is a critical requirement in these applications. Embedded processors supporting digital cameras must adhere to stringent power budgets despite the increased performance requirements to capture audio/video, drive LCD displays, and process high resolution images.
