Genie Processing Features
The Genie color series of cameras support a number of functions to enhance acquisitions or perform real time
processing. Functions can be combined to solve specific imaging situations. The user can enable and evaluate each
operation by using CamExpert.
Lookup Table (LUT)
The Genie camera includes a user programmable LUT as a component of its embedded processing features. The
LUT is used for operations such as gamma adjustments, invert and threshold processes. CamExpert has a number of
built in LUT operations for the user to explore (see
"
CamExpert LUT Controls
" on page 95
).
For color sensors, the LUT table is a RGB 8-bit LUT (8-bit in, 8-bit out for R,G, and B) as illustrated in the
following figure. Pixel data when read out of the sensor is passed through the LUT memory array, where the new
programmed pixel value is then passed to the Genie output circuit. The LUT data table is stored along with other
parameters with the user configuration function (see
"
Power-up Configuration
" on page 32
).
