The WDR core implements an efficient, low-power and low-latency High Dynamic Range (HDR) and Wide Dynamic Range (WDR) image processor that produces clear and sharp images under any lighting conditions.
The core receives two, three, or four exposures of the same frame, in 10- or 12-bit RGB Bayer format and any resolution up to Full-HD. It processes the input with proprietary, content-adaptive algorithms for merging exposures, local and global tone mapping, and contrast expansion, and it also supports white-balance adjustment, optical back correction, and a 2D noise reduction filter.
Being highly configurable and sensor-agnostic, the core addresses the needs of a wide range of applications. Run-time control over processing parameters enables users to adjust brightness, dynamic range, and sharpness to address the requirements of different use cases, and also provides the means to eliminate typical HDR/WDR processing artifacts such as flickering, shape deformation, and over-enhanced edges.
Merges 2, 3 or 4 exposures and supports programmable exposure times and speed of response to content changes
Implements Local & Global Tone mapping, 2D Noise Reduction Filter and White Balancing Adjustment and Optical Black Correction
Low Latency & Low Power: Just seven lines of latency - Does not need power-consuming DDR
Sensor-Agnostic and Tunable to Application Requirements
Mass production proven, LINT-clean design
Device Utilization and Performance
The WDR core can be mapped to any Intel FPGA Device (provided sufficient silicon resources are available) and optimized to suit the particular project's requirements. The core requires approximately 30K ALMs, 80 RAM blocks and 91 DSP blocks when configured to support 1080p60 video. Please contact CAST to discuss resource utilization and performance for your application and target device.
