TM/ RM -1327GE Series
The image quality depends on the camera's own pixel data (including pixel data independency from
neighboring pixels, noise and color filter), and interpolation of the software algorithm such as 3 x 3
interpolation, 2 x 2 interpolation, color matrix, white balance capability, etc.
All AccuPiXEL color cameras are carefully designed for maximum color performance. JAI strongly
suggests that you use digital output for the best performance.
Some software is used on board (FPGA or DSP) to perform the interpolation. Other software simply
uses the host computer's memory and CPU. The process speed may vary depending on the
architecture and speed of the computer.
8.3 Electronic Shutter
The TM-1327GE has a substrate drain-type shutter mechanism which provides a superb picture at
various speeds without smearing. A built-in flexible shutter speed control selects the electronic
shutter rate from 1/30 to 1/21,000.
With VINIT high (CC1), the CCD keeps discharging. With an active low pulse to VINIT, the camera
resets and purges the charge momentarily. Then it starts integrating for the period of shutter
control set by either an external pulse width or internal shutter control. Progressive scanning
permits a full 1040 lines of vertical resolution, as compared to a conventional CCD camera which
captures only half the vertical lines per shutter.
8.4 External Sync
The TM-1327GE accepts an external synchronization of standard HD and VD on CC3 and CC4 of the
Gigabit Ethernet connector for general locking to an external source. The tolerance is ±2%
horizontal frequency.
8.5 Asynchronous Reset
The TM-1327GE camera includes the following modes to control the asynchronous reset and shutter
speed:
•
Async No Shutter (recommended for strobe applications)
•
Async Direct Shutter
•
External VINIT with Pulse Width (No-Delay Shutter)
8.5.1
Async No Shutter
Async No Shutter allows for strobe and back-to-back strobing (strobing both before the transfer gate
and right after) applications as shown in Figure 30.
