Camelia Color 4M Camera
CCD Description
•
Image format: 28.7 mm (V) x 28.7 mm (H)
•
2048 mm (V) x 2048 mm (H) active pixels
•
Pixel Geometry: 14 µm (V) x 14 µm (H)
•
Filter Mosaic (Bayer Pattern):
Note:
The first active pixel of the first active line is blue.
•
Antiblooming by clocking.
Timing
•
2 x 2 and 4 x 4 pixel binning can be used to enable previewing modes.
•
When binning is used, the camera delivers black and white video.
•
The data rate is (pixel clock): 20 MHz.
Three timing modes are available:
•
Continuous
•
External triggered
•
Integration time controlled (ITC)
Continuous Timing Mode
The camera delivers frames continuously:
•
Frame N+1 integration starts as soon as frame N readout is completed (Figure 2).
•
Integration time is set by the RS-232 interface.
