Operation

TMC-6700/1000 Series Progressive Scan CCD Digital Color Camera

Note: In order to avoid video problems, make sure that you turn the shutter-speed control dial

quickly. If you turn the dial too slowly, the shutter may not expose for the proper period of

time, resulting in either no video or bright video. If this happens, push the IWB RST switch

on the rear panel or repeat the dial change at a faster speed.

3.1.3 White Balance Control Switch

The IWB/EWB switch selects between Internal White Balance (IWB) mode and External White

Balance (EWB) mode. When the IWB RST button is pressed, white balance is calibrated. When the

IWB RST button is released, the last calibration value is held internally. EWB preset values can only be

changed via RS-232C control.

3.1.4 IWB Reset Button

When held down, the IWB reset button calibrates the white balance so that the selected object appears

to be white. After it is released, the camera maintains the last white balance values.

3.1.5 Gamma Control Switch

The gamma control switch selects between gamma 1.0 and gamma 0.45.

3.1.6 Bank Switch

The camera features four memory banks that store camera configuration parameters such as shutter

speed, color matrix, white balance, gain, and edge enhancement. The first two banks, Bank1 and Bank2,

can be selected via the Bank Switch on the back panel of the camera. Bank3 and Bank4 can be selected

via RS-232C control. This feature allows easy switching between different camera-control parameters

as application needs change. Please refer to Section 4.1.2 on page 22.
