Claim 2:
3. The video processing device according to claim 1, wherein the format adjustment performed on the original video image by the normalization sub-circuits comprises resolution adjustment, and the target format comprises a target resolution;
the normalization processor further comprises a computation sub-circuit configured to compute the target resolution based on the received selection instruction and a parameter of a display; and a resolution of the original video image is smaller than the target resolution; and
the plurality of normalization sub-circuits of the normalization processor comprise:
an interpolation amplification normalization sub-circuit configured to perform resolution adjustment on the original video image in an interpolation manner to obtain a first video image with the target resolution;
a boundary filling normalization sub-circuit configured to fill a periphery of the original video image with pixels of a first color in a boundary filling manner to obtain a second video image of the target resolution; and
a pixel replicate normalization sub-circuit configured to, when the resolution of the original video image is M1×N1 and the target resolution is M2×N2 and if M2/M1=N2/N1=i, process the original video image in a pixel replicate manner to obtain a third video image of the target resolution, where i is an integer greater than 1; wherein the third video image comprises N1 rows and M1 columns of pixel groups each comprising i rows and i columns of pixels, and a plurality of pixels of a pixel group in an nth row and an mth column are obtained by replicating a pixel in an nth row and an mth column of the original video image, where 1≤n≤N1 and 1≤m≤M1.
