Abstract
An image reading apparatus reads a document on a line-by-line basis by using a reading unit. The image reading apparatus includes a modulation unit configured to modulate a clock signal at a predetermined period, a trigger signal generation unit configured to generate trigger signal for reading one line in the reading unit, a driving signal generation unit configured to generate a driving signal of the reading unit based on the clock signal output from the modulation unit and the trigger signal, and an output unit configured to change output timing of the driving signal within a range of the predetermined period each time the trigger signals are output predetermined times.
