Image processing method and apparatus

Abstract

An image recording apparatus for making index data from a part of image information read out of a recording medium. This apparatus comprises a memory for storing information regarding a character recognition error, a searching unit for searching the image information corresponding to search data, and a changing unit for changing a part of the search data on the basis of the information stored in the memory when the image information cannot be searched by the searching unit. Preferably, the change in search data by the changing unit is stopped by a predetermined instruction or when the number of changing operations has reached a predetermined number of changing times. Or, preferably, the search data can be rewritten to the index data by a predetermined instruction. If corresponding image information doesn't exist in the input search data, a part of the search data is changed in accordance with a character recognition error ratio which has previously been obtained, so that the image information can be searched even if there is a recognition error in the index data.
