Image processing method and cell fractionation method

Provided is an image processing method comprising: an image acquisition step (S1) of photographing a chip array obtained by dividing a substrate into multiple chips together with slices of biological tissue on the substrate, and acquiring a divided slice image including all the divided slices; a chip recognition step (S3) of recognizing chip images in the divided slice image; an attribute information assignment step (S4) of assigning, to each pixel composing a recognized chip image, position information within the image of the chip array, for the chip image to which that pixel belongs; and a restoration step (S5) of generating a restored slice image wherein the images of the divided slices are stitched together, by stitching together chip images comprising the pixels that were assigned position information. 提供种图像处理方法，包括以下工序：图像获取工序(S1)，对小片排列进行拍摄，获取包含已被分割的切片的整体的分割切片图像，该小片排列是将基板与该基板上的生物体组织的切片起分割为多个小片而得到的排列；小片识别工序(S3)，从分割切片图像中识别小片的像；属性信息附加工序(S4)，对构成识别出的小片的像的像素的各个像素附加该像素所归属的小片的像在小片排列的像中的位置的信息；以及复原工序(S5)，将包括被附加了位置的
