Image analyzing apparatus defining regions of interest

摘要

An image analyzing apparatus includes an image data memory for two-dimensionally and temporarily storing image data and is adapted for displaying an image on a CRT based on the image data temporarily stored in the image data memory and effecting a quantitative analysis. The image analyzing apparatus includes further includes a profile data producing section for producing profile data of density in a predetermined image region based on the image data temporarily stored in the image data memory and storing them in the image data memory and a region-of-interest defining section for defining a region of interest in a density profile displayed on the CRT based on the profile data. The region-of-interest defining section is constituted so as to define a region of interest when an instruction signal is received to define a new region of interest in such a manner that in the case where a single region of interest has been previously defined, if one end point of the region of interest to be newly defined is located in the previously defined region of interest and another end point of the region of interest to be newly defined is not located in the previously defined region of interest, it determines the other end point of the region of interest to be newly defined in accordance with the instruction signal and defines a new region of interest so as to be continuously adjacent to the previously defined region of interest irrespective of an input coordinate value of the one end point of the region of interest to be newly defined. According to the thus constituted image analyzing apparatus, it is possible to enable unskilled users to define a plurality of regions of interest in a density profile in a desired manner and to effect quantitative analysis on the regions of interest.
