CV-M300 1. General The CV-M300 is a monochrome 2/3" CCD camera designed for automated imaging applications featuring high performance and unique functions within a uniform and compact housing. The high-speed shutter function and asynchronous random trigger function allow the camera to capture high quality images of fast moving objects. It is suitable for industrial applications such as on-line inspection and measurements. In addition to conventional random trigger modes, the newly added pulse wi

CV-M300 6. Functions and Operations 6.1. Input/Output of HD/VD Signal 6.1.1. Input of External HD/VD Signal As factory setting the camera can be synchronized by external HD/VD signals. The signal level must be 4.0 Vp-p ± 2.0V at the input with the 75 Ohm termination ON. To change to non-terminated input, see instructions in “7. Mode Setting”. If no ext. HD is connected, the camera will switch to the internal X-tal controlled HD. If no ext. VD is connected, the camera will continue with its inter

CV-M300 Cautions in the Pulse Width Control Mode. 1. Pulse width control mode is effective only in non-interlaced field accumulation mode. 2. The exposure start may be delayed up to 1H max., when the falling edge of ext. trigger pulse is not synchronized with the falling edge of ext. HD signal. To avoid this 1H jitter and delay, the falling edge of the ext. trigger pulse should be synchronized within 4.4 usec. to the HD pulse. It can be the ext. HD in or the Internal HD out. See cautions in Edge

CV-M300 6.3.3. Start/Stop Trigger Mode The Start /Stop trigger will work in 3 modes: 1. Interlaced with frame accumulation. 2. Interlaced with field accumulation. 3. Non-interlaced with field accumulation. The exposure time is controlled by the interval between the ext. trigger pulse and the ext. VD signal. The exposure starts at the first HD pulse after the falling edge of the ext. trigger, and stops at the rising edge of the VD pulse. The range can be within 1/77 to 1/10,000 sec. The Start/Sto

CV-M300 Cautions in the Start/Stop Trigger Mode. 1. The input of ext. VD signal must be given continuously to synchronize with int. VD signal. It is not possible to input ext. VD signal randomly. 2. The exposure start may delay up to 1H max., when the falling edge of ext. trigger pulse is not synchronized with the falling edge of ext. HD signal. To avoid this 1H jitter and delay, the falling edge of the ext. trigger pulse should be synchronized within 4.4 usec. to the HD pulse. It can be the ext

CV-M300 6.3.4. Long Time Exposure Mode The Long time exposure will work in 3 modes: 1. Interlaced with field accumulation. 2. Interlaced with frame accumulation. 3. Non-interlaced with field accumulation. The exposure time is the interval between 2 ext. VD pulses sent to the camera VD input. Each ext. VD pulse will reset and restart the internal VD in the camera as for ext. HD/VD input. So the camera is synchronized to the external HD/VD supply after each VD input. An exposure starts after input

CV-M300 Cautions in the Long Time Exposure Mode. 1. Theoretical exposure time is as follows. EIA: 1/30 sec. to ∞. CCIR: 1/25 sec. to ∞. 2. It is recommended not to use exposure >2 sec. since visible dark-current noise may occur. 3. Ext. HD signal (4.0 Vp-p ± 2.0V at 75 Ohm terminated) has to be input continuously The falling edge of Ext. HD signal and Ext. VD signal are phase-synchronized. 4. Timing of ext. VD signal in each accumulation mode has to be set, as described before. a) 2:1 Interlaced

CV-M300 Cautions on Shutter. The image can flicker when the illumination is AC powered. Highlighted parts of the image will show increasing smear at a shorter shutter time. 7.1.4. Ext. Trigger Shutter Mode When trigger select SW1-4 is ON. The camera is in ext. trigger shutter mode. The SW1-1, SW1-2 and SW1- 3 are for selecting the shutter speed. The range is from OFF to 1/10,000 second in 8 steps. For each external trigger pulse, the camera will make an exposure with the selected shutter speed.

Adjustment of Video Signal Output Level When an alignment of a video output signal is required, remove the camera housing and adjust potentiometers VR3, VR4 and VR5 on the PK8042 board while measuring their levels at the video output connector. This adjustment should only be done in a setup with a standard TV test chart and controlled illumination. VR3: To adjust the gain level of AGC. (Factory setting: 700 mVp-p ± 30 mV) VR4: To adjust the white level. (Factory setting: 800 mVp-p ± 2
