Basic functions The CCD scanning format can be selected between full or partial scanning. With partial scanning only the vertical central part of the CCD sen sor is read out with a higher frame rate.
CV-M4 + /M4 + CL, CV-M7 + /M7 + CL - 9 - Binning mode is a func tion where the signal charge from 2 or more adjacent pixels are ad ded together and read out as one pixel. A resulting f ull frame with lower spatial resolution can be read out with a higher rate, and higher sensitivity.
CV-M4 + /M4 + CL, CV-M7 + /M7 + CL - 10 - Color versions CV-M7 + and CV-M7 + CL These color cameras are identical to the monochrome cameras. Only the CCD sensor is changed to a RGB primary color type. Here t he color mosaic lay out is shown in fig. 13.
CV-M4 + /M4 + CL, CV-M7 + /M7 + CL - 11 - Restart Continuous Trigger mode. RCT . The RCT mode makes it possible to use a lens wi th video controlled iris for intelligent traffic surveillance applications, ITS. The camera is running continuously, and the iris is controlled from the iris video output.
CV-M4 + /M4 + CL, CV-M7 + /M7 + CL 6.3. Continuous Operation (Non triggered) Mode settings can be done with either RS-232 C or switches. Trigger Mo de Normal. TR=0. It is for applications where the camera is continuous runni ng without external trigger.

CV-M4 + /M4 + CL, CV-M7 + /M7 + CL - 15 - 6.4. External Trigger Modes This camera has 3 external asynchr onous trigger modes, which can be s et by RS-232C commands or switches. 1. Edge Pre-select Mod e. TR=1 Pre-selected exposure. (SM=0, SM=1) 2. Pulse Width Control Mode.
CV-M4 + /M4 + CL, CV-M7 + /M7 + CL - 16 - 6.5. Edge Pre-select Mode The trigger leading edge will st art the exposure H synchronous or H a-synchronous (HC=0, H C=1). The exposure stops and is read out after the shutter time selected. It can be the 10 steps in normal or 1056 steps in programmable.
CV-M4 + /M4 + CL, CV-M7 + /M7 + CL - 17 - Remark that the dump read out in smearless takes 133H before the acc umulation start. Fig. 20A. Edge Pre-select, smearless Fig.
CV-M4 + /M4 + CL, CV-M7 + /M7 + CL - 18 - 6.6. Pulse Width Control Mode In this mode the exposure starts from the leadin g edge of the trigger pulse, H sync hronous or H a-synchronous. It stops at the trailing edge of the trigger pulse, and th e resulting video is read out.
CV-M4 + /M4 + CL, CV-M7 + /M7 + CL - 19 - 6.7. Frame-delay read out Mode In this mode the pre selected exposure starts from the leading edge of the trigger pulse, H synchronous or H a-synchronous. It can be the 10 steps in normal or 1056 steps in programmable.
CV-M4 + /M4 + CL, CV-M7 + /M7 + CL - 20 - 6.8. Frame-delay read out Mode with multiple exposure. Multiple exposures is possible in frame delay re ad out mode. The pre selected exposure starts from the leading edge of the trigger pulse. It can be the 10 steps in normal or 1056 steps in programmable.
CV-M4 + /M4 + CL, CV-M7 + /M7 + CL - 21 - 6.9. Other Functions. Functions which can be controlled by either RS-232C or swit ches, or both. Gain and set-up. !! Do not adjust these s ettings unless you have knowl edge to video adjustments !! The video gain is set to man ual .
