1.2 Available Functions of MLT (F)
This manual describes the operating procedures of the following three image processing functions that are available with MLT (F). For details and information on other image processing functions, please refer to Operation Manual and Setup Guide.
DWT*1 Edge Enhancement (→ P.7)
The DWT ENHANCE. tab provides the function to accentuate edge details of the exposure image by specifying the three parameters; the degree of enhancement (EFFECT), type of enhancement (FREQUENCY BASE), and type of density dependent of the image (DENSITY BASE).
The DWT DEP tab provides the function to compress the dynamic range of the exposure image by specifying the six parameters; the density to start compression (STARTING DENSITY), compression ratio (DEP WEIGHT), and intensity of compression (DEP EFFECT) for both the
The imaging area on film or monitor is widened by decreasing the pixel value range in the second region of interest, without changing the minute structures in the first region of interest.
The DWT NOISE R. tab provides the function to reduce the noise components of the exposure image, and improve it’s granularity by specifying the two parameters; the degree of enhancement (EFFECT) and upper limit of density (PROCESSING UPPER LIMIT).
NOTE: The effects resulting from changes to the parameters may be difficult to check in the exposure image of the QA mode screen.
In these cases, check by touching [MAG.] or
Display of the Tabs
At the time of installation, the service person can specify the fixed parameters, and set
MLT (F) not to display the tabs for the individual settings of the DWT Edge
Enhancement, DWT DEP and DWT Noise Reduction.
