In the embodiment of the present disclosure, the pathological section image is not limited to be divided according to the preset image block size, and other manners may also be adopted to divide the pathological section image. For example, the pathological section image may be equally divided into N image blocks, where N is the number of preset image blocks. For another example, the pathological section image may be divided such that the size of each image block obtained by dividing is within a preset interval. In the embodiment of the present disclosure, the sizes of different image blocks may be the same or different.

For example, the image blocks may be named in terms of [ number of layers ] _[ rows ] _[ columns ]. For example, the image block a in the lowermost layer pathological section image in fig. 2 may be named as [0] _ 2, and the image block in the lowermost layer pathological section image may be named as [0] _ [3] _ [4 ].
In this implementation manner, for any image block of the plurality of image blocks, the image block is named according to the number of layers of the pathological section image and the number of rows and columns of the image block in the array formed by the plurality of image blocks, so that the correspondence between the number of layers of the pathological section image, the number of rows and columns of the image block in the array formed by the plurality of image blocks, and the image block can be quickly established, and the image block can be conveniently searched.

indicating rounding up. And respectively determining the image blocks among the image block 1, the image block 2, the image block 3 and the image block 4 as the image blocks of the image area containing the request display in the pathological section image. For example, if the number of layers is 0, the image block 1 is an image block in row 5, column 3, the image block 2 is an image block in row 5, column 6, the image block 3 is an image block in row 4, column 3, and the image block 4 is an image block in row 4, column 6, the image block in row 5, column 3, column 5, row 5, column 6, row 4, column 3, column 4, row 4, column 5, and column 6 are determined as the image block in row 5, column 3, column 4, row 4, column 5, and column 4, respectivelyThe pathological section image comprises image blocks of the image area requested to be displayed.
