Claim 10:
11. The apparatus of claim 10, further comprising: a relative definition scoring model training module, which comprises:
a sequencing unit, which is configured to sequence sample images in a sample image set according to magnitudes of capturing focal lengths;
a labeling determination unit, which is configured to determine, in the sample image set after the sequencing, at least one clear sample image labeled;
an image group determination unit, which is configured to determine a plurality of paired sample image groups and a relative definition relationship between two sample images in each of the plurality of sample image groups according to the at least one clear sample image and the sequencing of the sample images in the sample image set;
an input unit, which is configured to input each of the plurality of sample image groups as training data into pre-established relative definition scoring model, wherein the pre-established relative definition scoring model is configured to determine a relative definition score of each of the two sample image according to multi-scale features of the two sample images in the each of the plurality of sample image groups; and
a training unit, which is configured to train the pre-established relative definition scoring model according to the relative definition relationship and the relative definition scores of the two sample images in the each of the plurality of sample image groups by using a contrastive loss function.
