1.7 Thermal Considerations The Osprey camera series has been carefully designed to separate the camer a electronics from the image sensor. Fairchild Imaging advises that if you are going to do any gain or offset corrections that you perform these functions after the camera has been turned on for at least 15 minutes. To do offset correct ion, cover [...]

SECTION 2 Camera Hardware Interface 2.1 Installation Overview Before you integrate your camera into your system you should first determine some basic operating parameters such as what resolution you need.

SECTION 6 Troubleshooting 6.1 Check Simple Things First Remember that the camera is part of t he entire acquisition system. You may have to trouble shoot any or all of the following: • Power supply • Frame grabber hardware & software • Light sources • Operating environment • Cabling • Host computer • Optics • Encoder 6.2 General[...]

EXSync Exsync must toggle (200 Hz min.). The camera will not output lines if ExSync is restricted to logic HIGH or logic LOW. Using an oscillosc ope, check the camera end of the control signal cable to verify that ExSync toggles. Offset Variation or Drifts The camera will experience offset drift and the dark level wi ll increase if the camera’s E[...]

Check the exposure time. If the images are too dark try increasing the exposure. Try decreasing the exposure if they are too bright. Check your light source. If the images are too dark, try increasing your light intensity. Try decreasing the in tensity if they are too bright. Check your gain setting. If the images are too dark, try increas ing the [...]
