IMAQPLOT is a simple demonstration of previewing video data using the toolbox s TimerFcn callback. IMAQPLOT also allows users to integrate the video preview into any MATLAB GUI. These are capabilities that are present in the toolbox s PREVIEW command, but are presented here as a demonstration of TimerFcn callback.



Using toolbox callback properties, you can configure a video input object to generate a live image plot display.



Do you want a basic preview window created for you? Simply call:



obj = videoinput( matrox , 1)

obj.TimerFcn = @imaqplot

obj.TimerPeriod = 0.1

obj.FramesPerTrigger = Inf

start(obj)



Do you want to add a preview window to an existing GUI? Simply provide IMAQPLOT a handle to an image object and it will update it for you:



obj = videoinput( dt , 1)

obj.TimerFcn = {@imaqplot, hImage}

obj.TimerPeriod = 0.1

obj.FramesPerTrigger = Inf
