Programmable Look-Up Table (LUT)

BM-500CL/BB-500CL has a programmable look-up table (LUT) that lets the user adjust the transfer
function of the video output.
Selectable settings include multiple-point LUT and Gamma 0.45.

The look up table has 256 setting points by which the full range of input signal is divided. On each
of the point, the gain can be set to get a required transfer function. In case of BB-500CL, Gr, R,
Gb and B signals have the same characteristics. Gamma 0.45 or programmable LUT can be
selected by software control. If the LUT is not configured, Gamma is set at 1.0 (OFF).

6.2.5.

Blemish Compensation circuit

BM-500CL/BB-500CL has a blemish compensation circuit. This function compensates for blemishes
on the CCD sensor (typically pixels with extremely high response or extremely low response). This
applies to both Monochrome and Color versions. Pixels that fulfill the blemish criteria can be
compensated by adjacent pixels on both columns. The numbers of compensation is up to 8 pixels
on both L and R channels. In case of BB-500CL, the defective pixels can be compensated by
adjacent same Bayer color pixels on both columns.
The compensation circuit can be enabled or disabled by software control. The factory default is
OFF.
