Abstract
An image analyzing apparatus for, producing a profile of density of a predetermined image region to display it on a CRT and effecting quantitative analysis. The image analyzing apparatus includes a profile data producing section for producing profile data of density of a predetermined image region, a background noise level calculating section for defining a region of interest in the profile displayed on the CRT based on the profile data produced by the profile data producing section and calculating the average value of density levels of pixels of image data corresponding to an image in the defined region of interest as a background noise level, and a profile data correcting section for subtracting the background noise level produced by the background noise level calculating section from the profile data produced by the profile data producing section to correct the profile data.
