階調信号を出力する制御手段と よりなる画像出力装置。[Claims for Utility Model Registration] An image sensor that reads characters, figures, images, etc. and obtains an analog signal at a level corresponding to the degree of shading thereof, and the analog signal level from the image sensor and the reading area of the image sensor. The threshold levels set differently for a plurality of pixels in a certain area are compared, and white information and black information are determined depending on the magnitude relationship between the analog signal level at each pixel and the threshold level set at each pixel. a comparator that obtains the information, and counts the number of white information in the certain area from the comparator, compares the threshold level at each pixel with the number of white information, and according to the result, the information at each pixel is determined as white information. or black information,
Depending on the judgment result, the corresponding pixel is determined by the density of the threshold level for that pixel, the density of the level of the number of white information, (
An image output device comprising a control means for outputting gradation signals for displaying at a density level of -1 (threshold value).
