Abstract
Systems and methods for hardware-accelerated key color extraction are disclosed. An update corresponding to a portion of a digital representation of a display screen is received. Key color information for locations within the update is identified. A data structure code associated with the portion of the digital representation of the display screen is determined based on the identification of the key color information. The data structure code is provided to a data structure. During a scan of the frame buffer for display, the frame buffer is capable of being read according to the data structure.
