Abstract:
1. A calibration apparatus comprising: a calibration section which performs calibration with a first image reading apparatus and a second image reading apparatus which read in-line a color patch formed on paper by an image forming apparatus which forms an image on paper; and an image signal conversion section, wherein the first image reading apparatus includes a first device which reads the color patch and outputs a result of the reading as a first signal, the second image reading apparatus includes a second device which reads the color patch and outputs a result of the reading as a second signal having a signal format different from a signal format of the first signal, the image signal conversion section converts the first signal into an after-conversion first signal having the signal format of the second signal, and the calibration section performs the calibration in such a way that an output value of the second signal is adjusted to an output value of the after-conversion first signal.
