7.3. Digital Video Output (Bit Allocation)
Although the CM-030GE/CM-030GE-RA and CB-030GE/CB-030GE-RA are digital cameras, the
image is generated by an analog component, the CCD sensor.
The table and diagram below show the relationship between the analog CCD output level and
the digital output.

The standard setting for 10-bit video level is 890 LSB. 200 mV CCD output level equals 100%
video output.

7.3.1 Bit Allocation (Pixel Format / Pixel Type) – CM-030GE/CM-030GE-RA
In the GigE Vision Interface, GVSP (GigE Vision Streaming Protocol) is used for an application
layer protocol relying on the UDP transport layer protocol. It allows an application to receive
image data, image information and other information from a device.
In the monochrome camera, CM-030GE/CM-030GE-RA, the following pixel types supported by
GVSP are available.
With regard to the details of GVSP, please refer to GigE Vision Specification available from
AIA (
).
