Abstract: An image processing system includes one or more processors operative to receive a graph application programming interface (API) call to add a complex node to a graph. The graph includes at least the complex node connected to other nodes by edges that are directed and acyclic. The one or more processors are further operative to process, by a graph compiler at compile time, the complex node by iteratively expanding the complex node into multiple nodes with each node corresponding to one operation in an image processing pipeline. The system further includes one or more target devices to execute executable code compiled from each node to perform operations of the image processing pipeline. The system further includes memory to store the graph compiler and the executable code.

Abstract: A color optimized CMOS photodiode pixel array is provided. The pixel array employs different dimensions to take advantage of different characteristics of the photodiode physics to produce an enhanced image while minimizing the need for post processing. The design includes a relatively shallow blue pixel photodiode, a deeper green pixel photodiode, and a relatively deep red pixel photodiode. The red pixel photodiode is larger and deeper than the green pixel photodiode, which is larger and deeper than the blue pixel photodiode. Each color pixel photodiode comprises a junction diode and a depletion region. The CMOS construction of the three color pixel photodiodes may vary, but one possible construct of the red pixel photodiode would be an N Well/P Sub diode construct, the green pixel photodiode a N+/P Sub diode construct, and the blue being a N+/P Well or N+/P Sub diode construct.
