Using a sequencer to vary image acquisition settings
A new TechTip, ‘Using the sequencer’, is available for download from IDS (Imaging Development Systems) which explains how the sequencer function can be used to vary image acquisition parameters of successive frames in IDS UI-124x/UI-324x/UI-524x and UI-125x/UI-325x/UI-525x industrial cameras featuring e2v CMOS sensors.
The sequencer function is particularly useful in applications where it is necessary to capture images of the same object with different camera acquisition parameters, for example to produce images with high dynamic range in applications with unknown light or brightness conditions.
Setting up the camera to perform a sequence of image acquisitions saves time by avoiding the need to adjust camera parameters after each image.
In sequencer mode, the user can define a particular area of interest (AOI) to acquire an image with a particular master gain and exposure time. Up to three further AOIs of the same size can then be specified, where different values for gain, exposure time, number of readout cycles and even AOI position can be specified. https://en.ids-imaging.com/techtipp.html
