An apparatus and method for retrieving image information in a computer. A controller receives a schematic image inputted by a user and normalizes the input image to an image of a constant size. A feature vector of each sub block of the normalized image is extracted, and the extracted feature vector is quantized to one of representative values of a determined number within feature vector space. An image profile indicating the frequency of occurrence of the feature vector of the input image is generated with respect to a quantizing level. A profile of the input image is compared with a profile of each image in an image data base part. An image corresponding to a profile whose similarity is within a reference value is displayed.
