How to get Image information (imtool) - Image description using command prompt function

I have developed algorithms which use certain inputs which are available in IMTOOL -> Tools->Image Information -> image description. How can I access this information through coding so that it will generalized and can avoid trouble at user end to provide those info. For instance in image description (attribute) for one of my image which is taken through LEICA microscope - i have the following details

Camera information: Calibration= 0.058 Microns per pixel; Capture format= 1024 x 768,     XGA HQ; Gamma= 0.77; Gain= 2.5 x; Exposure= 1.0 s; Auto exposure= Off; Image type= Colour; Shading= Test 1; Sharpening= High; Black clip= 5; White clip= 229; 
Microscope information: Nosepiece Objective Mag.= 100; Mag changer magnification= 1; Aperture= 1.25;

Some of these information are being used for processing.

Look at imfinfo.

Ashish ...

I have tried using that and the image description details which i got through IMTOOL are mentioned above and the imfinfo doesn't cover all those

here is the result for IMFINFO

imfinfo('leishman pf gametocyte.jpg')

You can see the information such as calibration / gamma etc are missing which are required for me.

You could *try* http://www.mathworks.com/help/techdoc/ref/exifread.html

Gamma does not appear to be on most JPEG tag sets,http://www.sno.phy.queensu.ca/~phil/exiftool/TagNames/JPEG.html

but it is a known EXIF tag, 0xa500

Cameras tend to use colorspace response profiles rather than using just one gamma for all spectral frequencies.

By using function imfinfo ---> image description [1x350 char] {as above} provide the required information..!

'Camera information: Calibration= 0.116 Microns per pixel; Capture format= 1024 x 768, XGA HQ; Gamma= 0.56; Gain= 2.5 x; Exposure= 1.0 s; Auto exposure= Off; Image type= Colour; Shading= Test 1; Sharpening= High; Black clip= 5; White clip= 255; Microscope information: Nosepiece Objective Mag.= 100; Mag changer magnification= 1; Aperture= 1.25; '

thanks for your time guys ...

Does Windows see them? Or another imaging package?
