1. A color calibration method applied to an image-forming device, comprising:
determining whether there is a first task, wherein the first task is an image-forming task being executed or an image-forming task to be executed;
when the first task exists, acquiring a size of a first imaging medium corresponding to the first task;
determining whether the size of the first imaging medium is within a preset range; and
when the size of the first imaging medium is within the preset range, executing the first task and a color calibration task at the same time, wherein the first task is output in a target area of a first imaging area and the color calibration task is output in a second imaging area of the first imaging area, a position of the second imaging area is determined by at least one counterpoint sensor of the image-forming device,
wherein
the image-forming device includes an intermediate transfer belt, the intermediate transfer belt being larger than the first imaging area;
the image-forming device includes two detection devices located on adjacent sides of the intermediate transfer belt;
a projection area of a detection area of the two detection devices projected on the first imaging area is the second imaging area; and
the adjacent sides of the intermediate transfer belt include a right side and a lower side of the intermediate transfer belt, or a left side and an upper side of the intermediate transfer belt.
