Hi everybody and thanks for your help. I need to know at which frame rate i'm working with the following lines code, and then i'd like to if it's possible to set the frame rate by myself and how to do it. Here there are the lines code:

clear all

a = imaqhwinfo; [camera_name, camera_id, format] = getCameraInfo(a);

vid = videoinput(camera_name, camera_id, format);

% Settiamo le proprietà dell'oggetto video set(vid, 'FramesPerTrigger', Inf); set(vid, 'ReturnedColorspace', 'rgb') vid.FrameGrabInterval = 5;

where getCameraInfo is

function [camera_name, camera_id, resolution] = getCameraInfo(a) camera_name = char(a.InstalledAdaptors(end)); camera_info = imaqhwinfo(camera_name); camera_id = camera_info.DeviceInfo.DeviceID(end); resolution = char(camera_info.DeviceInfo.SupportedFormats(end));
