Image Processing Techniques and Applications

A fast (NTSC TV-rate), low cost, simple histogram equalization processor is described. In this apparatus, the histogram equalization processing is carried out by the table look-up method at TV-rate. The characteristics of the processor, and its applications to the real time and on-line processing of weak contrast images from the Ultra-High Voltage Electron Microscope (Osaka University) are described. With this apparatus, equilevel processing, level compression, and level slicing may also be easily carried out.
