ABSTRACT:
An image data monitor apparatus has a CCD for reading image data of a document, an input buffer for receiving the pixel data from the CCD, an image processor for processing the data received from the CCD for printing out an image or the like, a circuit including a counter for extracting the designated pixel data, a keyboard for setting a desired mode, LEDs for displaying the extracted pixel data and other data, and a CPU for controlling the operation of the overall system. Various data such as maximum and minimum values of, an average value of or a maximum difference between the pixel data can be monitored at high speed upon selecting a corresponding mode. Desired data processing can be performed based on the monitored data.
