In this article, we’ll first look at the basics of representing a digital image. Then, we’ll discuss some simple operations that allow us to adjust the brightness and contrast of an image. Finally, we’ll briefly look at the circuit implementation of these operations.

In part 12 of Resolving the Signal, we look at a power-supply noise design example to discuss which supplies are most critical when trying to increase a system's PSR. From that example, we offer best practices to maintain low power-supply noise and debugging tips for a system's overall noise performance.

Part 9 of the Resolving the Signal series analyzes several different methods for reducing reference noise's effect in systems and examines the difference of reference noise's impact on low- and high-resolution ADCs.

Part 5 of this 12-part series continues to explore effective noise bandwidth as it relates to delta-sigma ADCs and system-level design by stepping through a simple example using a two-stage filter to understand how to calculate the ENBW and how system changes affect the ENBW.

SoCs with programmable logic are an essential element of real-time embedded vision systems. Designers can capitalize on the power and efficiency of Xilinx's Zynq Ultrascale+ MPSoC devices to implement their designs using Avnet's Embedded Vision Kits and the Xilinx reVISION stack.
