PROBLEM TO BE SOLVED: To provide an image reader capable of reducing the capacity of a delay memory. SOLUTION: This reader is provided with a read means of color image data by a three-line image sensor, a line correction processing means 21 that corrects an inter-line distance of the three-line image sensor, an in-area attribute discrimination processing means 22 that divides a read image M×N areas and discriminates the attribute of the image in each divided area as a character/ a photograph/a dot or the like, and a filter processing means 24 that applies two-dimension filter processing to the read image. Then the line correction processing means 21 and the in-area attribute discrimination processing means 22 receives the input image signal at the same time and conduct parallel processing on the circuit configuration.
