Motion Generators

Motion Generators to Test the Effects of Moving Objects on Image Quality

Imatest’s range of motion generator systems enable testing of image quality in moving scenes, allowing you to simulate motion blur and other effects that effect the image. These systems enable repeatable testing of image stabilisation routines that are designed to compensate for camera motion that arise from hand tremors and vibrations.

Camera Timing Test SystemImatest IQL Camera Timing Test System  

Datasheet

Test exposure and timing of cameras using 8 rows of scrolling LEDs along with roll-over counters. Each row can be independently configured for faster testing of multiple exposure times without having to adjust settings.

Specifications:

  • 8 Independently configurable rows (100 LEDs/row).
  • Buzzer chirp feature.
  • Time-Period Range: 100ns (10MHz) – 9999ms (0.1Hz).
  • Accuracy: 5μs.

 

Control Interface:

  • USB configuration & control via Windows GUI application or serial commands.
  • Trigger input to start.
  • Trigger output on start.
