SECTION 1 FEATURES AND APPLICATIONS PRECISE IMAGE GEOMETRY On the CCD image sensor, the photosensor elements form exact rows both horizontally and vertically so that a very precise image geometry may be obtained. HIGH RESOLUTION, INTERLINE TRANSFER CCD The TM-7/TM-6 series are state-of-the-art CCD cameras which use a 1/2 inch high resolution imager.

4.2 SHUTTER CONTROL UNIT (SC-745)- consists of a manually controlled 8-position BCD switch that determines the exposure time of the sensor. It connects to the TM-7CN/TM-7EX via a cable with a PC-6P male connector that plugs into the 6-pin female connector socket on the back of the camera. The SC-745 shutter control is included with the camera.
5.3 ATTACHING THE VIDEO OUTPUT Most users utilize the BNC connector on the "CN" and "EX" versions for video output from the camera. Connect the output from the camera to the input of your monitor, VCR, or switching device. The input of the monitor should be balanced for 75Ω termination. Standard RG-59 type coaxial cable should carry a full video signal for up to 500 feet. 5.4.2 AUTO-IRIS LENS SETUP Power down the camera before attaching auto-iris lens.
SECTION 6 Normal operation requires the CCD chip to construct an individual potential well at each image cell. These potential wells are separated from each other by a barrier. The barrier is sequentially removed to transfer the charge from one CCD to another by the pixel clock. This is the basic principle of CCD operation for interline transfer. The substrate drain vertically moves the charges.
SECTION 7 CCD CHARACTERISTICS AND OPERATION 7.2 MECHANISM OF CCD CHARGE TRANSFER 7.1 THEORY OF OPERATION (Operation principle of the CCD) A CCD (Charge Coupled Device) consists of MOS (Metal-Oxide-Semiconductor) capacitors arranged in a regular array. It basically performs three functions connected with handling charges: 1. Photoelectric conversion (photosensor). Incident light generates charges on the MOS capacitors, with the quantity of charge being proportional to the brightness. 2.
charge flows into the deeper wells toward the electrode at H2. At t3, the electrode voltage has not changed since t2, so the charge flows into the wells at H2 and one transfer of charge is completed. These operations are repeated to execute the horizontal transfer. 7.4 FIELD MODE AND FRAME MODE Standard factory setting for this mode selection is FIELD MODE. The difference of these two modes is as follows: FRAME MODE It scans each horizontal row as interlace scanning.
