ABSTRACT:
A scanning apparatus for reading an image having a line sensor composed by positioning a plurality of sensing devices in line for reading an image of a document, a motor for moving the line sensor and the document relatively, the motor making a motion to move the line sensor at a right angle with a direction of an arrangement of the sensing devices, an analog-to-digital (A/D) converter for converting a first anaglog image signal output from the line sensor to a first digital image signal, a memory for storing the first digital image signal, a memory controller for generating a write signal to the memory and for appointing an address at which the first digital image signal is written in the memory according to each writing mode, each writing mode being used to determine a sequence to appoint the address, a selecting circuit for selecting the writing mode by controlling the memory controller, and a digital-to-analog (D/A) converter for converting a second digital image signal output from the memory to a second analog image signal.
