Abstract: The present invention provides a document processing apparatus, document processing method and a storage medium for storing thereof on purpose to offer document filing in which document can be registered with a little computation cost and with high speed, and retrieval can be performed with little oversight. In the document processing apparatus, a similar character classifying element classifies characters in a document image into similar character categories in advance and stores the classified categories together with their representative image features. When the document image is registered, a pseudo character recognizing element executes, without identifying each character in the text region, classification into character categories based on the image features less than those used in the ordinary character recognition and stores the category strings generated by identifying each character with the inputted image.

Abstract: A pulse frequency modulation type DC-DC converter has first and second voltage level comparators for controlling the frequency of a control signal used to drive an output coil. The first voltage comparator detects a first voltage level and the second voltage comparator detects a second voltage level. A reference voltage circuit produces reference voltages corresponding to the first and second voltage levels and provides the reference voltages to the first and second voltage comparators, respectively. An oscillating circuit generates the control signal under control of the first and second comparators. The control signal has one of a first pulse width and a second pulse width depending upon outputs of the first and second voltage comparators for controlling a switching device used for driving an output coil. The switching device is turned on to drive the output coil during a first pulse width when the first voltage comparator detects that the output voltage coincides with the first voltage level.
