i want to capture an image through fish-eye camera in real time and use that image for processing.can anybody suggest me how to do it

I used this code but it is using a webcam as an input for the video. I want to use a fish-eye camera instead. Please help.

% if(~isdeployed)
%        cd(fileparts(which(mfilename)));
% end
% clc;
% Clear command window.
% clear;
% close all;
% Close all figure windows except those created by
% imtool close all;
% Close all figure windows created by imtool.
% workspace;
% Make sure the workspace panel is showing.
% fontSize = 36;
% % Start up the video.
% vid = videoinput('winvideo', 1, 'RGB24_640x480');
% vid.FramesPerTrigger = 1;
% preview(vid);
% start(vid);
% Get image and display it.
% rgbImage = getdata(vid);
% subplot(1,2, 1);
% imshow(rgbImage);
% title('Initial Image', 'FontSize', fontSize);
% set(gcf, 'Position', get(0,'Screensize'));
% Save this image to disk.
% fullImageFileName = fullfile( 'C:\Users\div\Desktop\myfirstimage.jpg');
% imwrite(rgbImage,fullImageFileName);
% Read it back in to check it.
% recalledImage = imread(fullImageFileName);
% subplot(1,2, 2);
% imshow(recalledImage);
% title('Recalled Image', 'FontSize', fontSize);

Other than the video mode name used in videoinput() might be different for a different camera model, why do you think the code should be any different than it is for a webcam or any other digital camera?

i just want to know how can i use fish -eye camera for image capturing in matlab...what changes i need to make..what will be the videoinput() value.

You will see a list of video modes that that camera uses when you run imaqtool. You can turn any camera into a "fish eye" camera if you can change to a wide angle lens on it (a lens with a very very short focal length). It's the lens that determines "fish eye", not the camera.

whenever i use the fish-eye camera(IEEE-1394 Digital camera).imaqtool shows this availabiliby of camera as pointgrey adaptor and deviceid 1..but when i run the code i get error as "unable to convert to the specified format7 .and matlab closes in an unexpected way..what should i do

imaqhwinfo

ans =

    InstalledAdaptors: {'gentl'  'gige'  'matrox'  'pointgrey'  'winvideo'}
        MATLABVersion: '8.0 (R2012b)'
          ToolboxName: 'Image Acquisition Toolbox'
       ToolboxVersion: '4.4 (R2012b)'

>> imaqhwinfo('pointgrey')

ans =

       AdaptorDllName: [1x82 char]
    AdaptorDllVersion: '4.4 (R2012b)'
          AdaptorName: 'pointgrey'
            DeviceIDs: {[1]}
           DeviceInfo: [1x1 struct]

this is the list of adaptors available
