Image processing apparatus

摘要: An image processing apparatus for reading an pattern such as characters, graphics or the like written on a printed matter comprises: lamp illuminating pattern; photo-sensor unit converting light reflected from to electrical signal multi-value digital data; converter output data binary value basis of maximum and minimum this control controlling so stabilize data. With apparatus, is converted mechanical vibrational enlarged display due piezoelectric elements LEDs, thereby enabling blind person with poor vision easily certainly perceive characters graphic information matter.
