The Image Display

Access the Image Display from the main 1D windows:
The optimum display window is helpful to enhance the image display by modifying the image greyscale
selection to be displayed.
Some images has a 12, 14 or 16-bit format and Windows® can only display 8-bit images (256 grey levels).
Due to this limitation, the FireReader 1D Advanced software handles two images:
- A "memory" image corresponding to the 12, 14 or 16-bit format (4 096, 16 384 or 65 536 grey
levels)
- A "displayed image" corresponding to the image displayed on the screen (256 grey levels)
The easiest way to calculate the "display image" would be to translate the full grey scale each time an
image is acquired: the x grey levels values of the "memory" image corresponds to 256 values in the
displayed image. In that case, it won't be possible to visualise faint spots on a dark image.
FireReader 1D offers the possibility to select the grey level range to translate for the display image
calculation. All the grey levels under the "Min value" defined will be converted to 0 (Black) in the displayed
image. All the grey levels upper the "Max Value" defined will be set to 255 (White) in the displayed image.
The grey levels between those two limits will be converted in an intermediate grey level value following a
linear rule.
For both values, you can:
