1. An image processing apparatus comprising:
a scanner; and
a controller,
wherein the controller determines whether the scanner has a first sensor or a second sensor, the first sensor having a length in a main scanning direction greater than a maximum length in a sub-scanning direction in which reading is performable by change a position of the first sensor, the second sensor having a length in a main scanning direction less than a maximum length in a sub-scanning direction in which reading is performable by change a position of the second sensor, and
wherein, in a case where the controller determines that the scanner has the first sensor, the controller executes, to read an image of one document placed on a platen glass, processing of changing the position of the first sensor from a reference position to a predetermined position in the sub-scanning direction twice, based on one execution instruction input by a user, and then generates first image data and second image data, an image of the first image data being same with an image of the second image data, and the controller outputs first extraction data generated by executing first extraction processing on the first image data, as one piece of page data, and outputs second extraction data generated by executing second extraction processing on the second image data, as one piece of page data, and
wherein, in a case where the controller determines that the scanner has the second sensor, the controller executes, to read an image of one document placed on the platen glass, processing of changing the position of the second sensor from a reference position to a middle position in the sub-scanning direction and processing of changing the position of the second sensor from the middle position to a terminal position in the sub-scanning direction, based on one execution instruction input by the user, and then generates third image data and fourth image data, and the controller outputs the third image data, as one piece of page data, and outputs the fourth image data, as one piece of page data.
