How can I change the aspect ratio of an image display

[marinvms]

I am snapping a sequence of images and using imgPlot to diplay the images. However, due to my camera specifications [it's a Pulnix 9701 with Pixel Size 11.6μm (H) X 13.3μm (V)], the image I get displayed is elongated in the horizontal direction, i.e. if I snap an image of a square, I get a rectangle on my computer display.
How can I change the aspect ratio of the display on my computer? The only parameters I have seen so far just control what portion of the image is acquired or diplayed, but none actually changes the aspect ratio.

Thanks in advance for any help.

If you are using an analog camera, you can set the aspect ratio in MAX. This will correct for non-square pixels.

If you are using a digital camera, I don't think there is a way to fix it during acquisition. You could resample the image to correct the ratios, but that would be a slow, time consuming process.

One other possibility is that your computer monitor is in a mode which is not a standard 4x3 configuration. For example 640x480 and 800x600 are 4:3 ratios. 1200x1024 is not, which tends to distort your displayed images.
