CV-M50 1. General The CV-M50 is a monochrome 1/2" 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 widt

CV-M50 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 4.0V p-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 inte

CV-M50 To use this mode Set: SW1-4 to ON for ext. trigger shutter SW1-5 to OFF for field accumulation SW1-6 to ON for non-interlaced SW1-1,2 and 3 to shutter speed Input: Ext. trigger to pin 5 on 6 pin multi connector. Ext. HD to pin 6 on 12-pin multi connector. (If used). 75 Ohm termination is done with SW2-1 (HD) and SW2-2 (ext.trigger) on PK8057 board. Refer to Timing Chart and Cautions below. Detailed switch and jumper setting is described in “7. Mode Setting”. For connections see “5. Pin As

CV-M50 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-M50 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/Stop

CV-M50 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-M50 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-M50 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 Int. 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

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. The shutter time setting is shown in “7.1.3. Table for Shutter Time”. 7.1.5. Trigger Select SW1-4 is will select the camera operation mode. OFF is normal mode, where

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 PK8056 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.
