5. CFMDSC
This block performs image processing such as smoothing and SCC to CFM data, and
constructs a CFM image data by Scan Conversion.
6. BWDSC
This block performs image processing, such as Enhance and SCC to monochrome data, and
constructs a monochrome image data by Scan Conversion. And monochrome image data is
compounded with the CFM image data from the CFMDSC block, and is transmitted to a
video board.
4.2.5.2 BW Echo Processing
A processing flow is shown in the following
Envelope
Pre-Gamma
Log
１． Detects envelope by orthogonal detection for complex data.
２． Applies logarithmic compression to image data that is now
intensity information.
３． Applies gamma correction to image data applied with
logarithmic compression.
