Document Type and Number:
Japanese Patent JP7491200
Kind Code:
B2
Abstract:
An image inspection apparatus includes a first reader and a second reader that acquire read images by respectively reading one side and the other side of a sheet having an image printed thereon, a first background material and a second background material provided at positions as the backgrounds of the sheet in reading by the first reader and the second reader respectively, and a hardware processor that acquires sheet outline information from the read images and measures misalignment of the image with respect to the sheet based on the acquired sheet outline information. The hardware processor acquires read images with the first background material and the second background material having different densities, and acquires sheet outline information of one read image by estimating the sheet outline information of the one read image based on sheet outline information of the other of the read images.
