Functionality
This chapter serves as an overview of the camera configuration modes and explains camera
features. The goal is to describe what can be done with the camera. The setup of the cameras
is explained in later chapters.
5.1 Reduction of Image Size
With the Photonfocus 1280 camera series there are several possibilities to focus on the
interesting parts of an image, thus reducing the data rate and increasing the frame rate. The
most commonly used feature is Region of Interest (ROI).
5.1.1 Region of Interest (ROI)
Some applications do not need full image resolution. By reducing the image size to a certain
region of interest (ROI), the frame rate can be increased. A region of interest can be almost
any rectangular window and is specified by its position within the full frame and its width (W)
and height (H).
The ROI width must be a multiple of 2.
A list of common image dimension and its frame rates is shown in Table 5.1. There is a frame
rate calculator in the support section of the Photonfocus web page www.photonfocus.com.
ROI Dimension [Standard] D-120
1280 x 1024 (SXGA) 65 fps
