1. A detection method for an image segmentation manner, comprising:
obtaining four sub-images input by a serial digital interface and formed by dividing an original image;
extracting four groups of reference pixel points from the four sub-images according to a set extraction manner, and each group of reference pixel points including a plurality of pixel points, wherein the set extraction manner is to extract at least two columns or at least two rows of pixel points at a connecting position of every two sub-images that are connected;
calculating pixel difference values of pixel points according to the four groups of reference pixel points; and
determining an image segmentation manner of the serial digital interface according to the pixel difference values;
wherein the two sub-images that are connected are a first sub-image and a second sub-image, the first sub-image includes a plurality of first pixel points, and the second sub-image includes a plurality of second pixel points;
for a first sub-image and a second sub-image that are connected in a row direction, an extracted group of reference pixel points includes: at least one column of first pixel points of the first sub-image at a connecting position where the first sub-image and the second sub-image are connected in the row direction, and at least one column of second pixel points of the second sub-image at the connecting position where the first sub-image and the second sub-image are connected in the row direction; and
for a first sub-image and a second sub-image that are connected in a column direction, an extracted group of reference pixel points includes: at least one row of first pixel points of the first sub-image at a connecting position where the first sub-image and the second sub-image are connected in the column direction, and at least one row of second pixel points of the second sub-image at the connecting position where the first sub-image and the second sub-image are connected in the column direction.
