  • Patent number: 10819873
    Abstract: An image processing apparatus capable of suppressing degradation of the image quality of output image data, caused by electrostatic noise, without increasing a circuit scale. The image processing apparatus transmits image data obtained by reading an original, in synchronism with a synchronization signal. Noise in the synchronization signal is detected and eliminated. An image is printed using the image data. The number of times of detection of the noise is counted, and a notification indicative of the number of times of detection of the noise is made.
