In an image processing apparatus, after a current band of an image has been read, an original is fed at a distance of the upper half band width of the current band. When the next band is read, the current band at the lower half band width is overlappingly read. The band data at the lower half band width of the current band is stored in a memory, and the next band is read. Averaging processing or function processing is applied to the band data which has been overlappingly read.

1. An image processing apparatus comprising: a reading unit adapted to read an original at a predetermined reading width in a main scanning direction; a controlling unit adapted to control said reading unit and the original so as to move relative to each other in the main scanning direction and
1. An image processing apparatus comprising: a reading unit adapted to read an original at a predetermined reading width in a main scanning direction; a controlling unit adapted to control said reading unit and the original so as to move relative to each other in the main scanning direction and a sub scanning direction, where, in a first main scanning direction, said reading unit reads the original at the predetermined reading width and, in the sub scanning direction, said original is fed by 1/x (x is a real number larger than 1) of the predetermined reading width, and in a subsequent main scanning direction, said reading unit overlappingly reads the original at the predetermined reading width; and an image processing unit adapted to apply predetermined image processing to an overlapped part of the image data of the original read by said reading unit. 2. An image processing apparatus according to claim 1, wherein 1/x is equal to or smaller than l/2. 3. An image processing method comprising: a reading step, of reading an original at a predetermined reading width in a main scanning direction; a controlling step, of controlling a reading unit and the original so as to move relative to each other in the main scanning direction and a sub scanning direction, where, in a first main scanning direction, the reading step reads the original at the predetermined reading width and, in the sub scanning direction, said original is fed by 1/x (x is a real number larger than 1) of the predetermined reading width, and in a subsequent main scanning direction, the reading step overlappingly reads the original at the predetermined reading width; and an image processing step, of applying predetermined image processing to an overlapped part of the image data of the original read in the reading step. 4. An image processing method according to claim 3, wherein 1/x is equal to or smaller than 1/2. 5. A computer-readable storage medium for storing a program for image processing, the program comprising: code for a reading step, of reading an original at a predetermined reading width in a main scanning direction; code for a controlling step, of controlling a reading unit and the original so as to move relative to each other in the main scanning direction and a sub scanning direction, where, in a first main scanning direction, the reading step reads the original at the predetermined reading width and, in the sub scanning direction, said original is fed by 1/x (x is a real number larger than 1) of the predetermined reading width, and in a subsequent main scanning direction, the reading step overlappingly reads the original at the predetermined reading width; and code for an image processing step, of applying predetermined image processing to an overlapped part of the image data of the original read in the reading step. 6. A computer-readable storage medium for storing a program for image processing according to claim 5, wherein 1/x is equal to or smaller than 1/2.
