1.19.1.5.1 Introduction
The CCD sensor is a highly programmable imaging module which will, for example, enable the following type of
applications
Industrial applications:
• triggered image acquisition with precise control of image exposure start by hardware trigger input.
• image acquisition of fast moving objects due to:
– frame exposure, integrating all pixels at a time in contrast to CMOS imager which typically integrate
line-by-line.
– short shutter time, to get sharp images.
– flash control output to have enough light for short time.
Scientific applications:
• long time exposure for low light conditions.
• optimizing image quality using the variable shutter control.
1.19.1.5.2 Details of operation
The process of getting an image from the CCD sensor can be separated into three different phases.
1.19.1.5.2.1 Trigger
When coming out of reset or ready with the last readout the CCD controller is waiting for a Trigger signal.
The following trigger modes are available:
Mode Description
Continuous Free running, no external trigger signal needed.
OnDemand Image acquisition triggered by command (software trigger).
OnLowLevel As long as trigger signal is Low camera acquires images with own timing.
OnHighLevel As long as trigger signal is High camera acquires images with own timing.
OnFallingEdge Each falling edge of trigger signal acquires one image.
OnRisingEdge Each rising edge of trigger signal acquires one image.
OnHighExpose Each rising edge of trigger signal acquires one image, exposure time corresponds to pulse
width.
