Abstract:
An image reading apparatus comprises a light source for repeatedly emitting first light having a first color, second light having a second color and third light having a third color toward a read target while moving the light source in a sub-scanning direction, first, second, and third sensors, each configured to sense a strength of first, second, and third reflected light, respectively, in a light reflected from the read target, and to output first, second, and third signal waveforms corresponding to the strength of the first, second, and third reflected light, respectively, and a controller. The controller is configured to execute a line-to-line correction for correcting a phase shift between the first, second, and third signal waveforms, and to correct a shift in a signal level caused by the line-to-line correction.

Claim (Index 1):
An image reading apparatus, comprising:\n a light source configured to repeatedly emit first light having a first color, second light having a second color different from the first color, and third light having a third color different from the first and second colors, at different times toward a read target while moving in a first direction; first, second, and third sensors, each configured to sense a strength of the first, second, and third lights, respectively, reflected from the read target, and to output first, second, and third signal waveforms, respectively, the first signal waveform corresponding to the strength of the first light sensed by the first sensor, the second signal waveform corresponding to the strength of the second light sensed by the second sensor, and the third signal waveform corresponding to the strength of the third light sensed by the third sensor; and a controller configured to execute a line-to-line correction for correcting a phase shift on the first, and third signal waveforms, and to correct a shift in a signal level of the second signal waveform caused by the line-to-line correction.
