摘要： A dichromatic reading device is disclosed in which the difference is taken between output signals from a first image sensor receiving reflected light directly and a second image sensor receiving the reflected light after being passed through a filter which blocks a specific color component of the reflected light. The difference is converted into a binary signal which provides one color image information and which together with a binary signal obtained from at least the second image sensor and inverted, is NANDed to provide a second color image information.
