Notes on specifications
Frame memory
Normally, an image is captured and transported in consecutive steps. The image is
taken, read out from the sensor, digitized and sent over the GigE network. Prosilica
GC cameras are equipped with an image buffer. The memory operates according to
the first in, first out (FIFO) principle. Specification tables show how many frames
can be stored by each model.
Resolution and ROI frame rate
This section charts the resulting frame rate from changing sensor height from full
image to a single line. Unless otherwise noted, sensors do not give an increase in
readout speed with a reduction in width.
Dimensions and mass
Dimensions include connectors but not the tripod and lens.
Mass does not include the tripod and lens.
Hardware version
This chapter includes camera specifications for all Prosilica GC models (hardware
revision D). For previous Prosilica GC models (hardware revision A) see
Hardware version incompatibility
Prosilica GC hardware version D models and firmware are not compatible with Pro-
silica GC hardware version A models.
Number of frames
The number of frames (
StreamHoldCapacity
) depends on resolution, pixel
format, and GigE Vision Streaming Protocol (GVSP) packet size. The stated number
of frames is typical for full resolution, Mono8/Bayer8, and a
GevSCPSPacketSize
=
8192
bytes per packet.
Resolution and ROI measurements
•
Data was generated using
StreamBytesPerSecond
= 124 MB/s (full
bandwidth) and an 8-bit pixel format. Frame rates may be lower if using
network hardware incapable of 124 MB/s.
•
ROIs are taken as center image for maximum speed advantage, where feature
OffsetY
= (full sensor height – ROI height)/2.
•
BinningVertical
is horizontal row summing on CCD before readout. The
frame rate for an ROI at the same effective height as binning is slower because
the CCD still needs to read out the “fast readout rows” in ROI mode.
