[0053] S1: respectively obtaining each image area of ​​the image to be printed;

[0054] Specifically, the image area of ​​the image to be printed includes a vector image area and / or a bitmap area, which can be understood as the image to be printed is a bitmap, or a vector image, or a combination of a bitmap and a vector image; the bitmap and vector image can be further divided into color blocks, color images and other graphics according to the actual pattern image; wherein the color block represents the pure color of a certain area, such as the background color, or the color area connected to the pattern, and the color image represents the specific image in the pattern, such as people, trees, buildings, weavings and other patterns with certain forms; the areas corresponding to other patterns are divided into other graphics, such as cabinet geometric figures and / or irregular geometric figures that are embellished on the background color, or lines and other patterns that do not have specific forms.

[0055] S2: dividing each of the image regions into a plurality of different image sub-regions;

[0056] Specifically, each image area has multiple similar images, and then these images are further segmented according to their differences to obtain multiple image sub-areas; for example, the color types included in the color block are further segmented; divided into sub-areas with the same color; the characters in the color picture are further segmented into the character body, decorations and clothing, etc. There is no specific limitation on the way of dividing the image sub-areas, as long as the divided image sub-areas can achieve differentiated printing in the same image area.

[0057] S3: Setting a corresponding image processing method for each of the image sub-regions;

[0058] Specifically, the image processing method of each image sub-region is set according to the highlighting requirements of each image sub-region. For example, if the yellow area in the color block needs to be highlighted, the image sub-region corresponding to yellow needs to have its brightness increased; for example, if the decorations in the hands of a person need to be highlighted, the image display of the surrounding areas needs to be weakened.

[0059] S4: performing image processing on the image data corresponding to each of the image sub-regions according to the image processing method corresponding to each of the image sub-regions to obtain actual image data of the image to be printed.

[0077] Figure 4 A schematic diagram of the process flow of the image partition processing method provided in this embodiment;

[0078] like Figure 4 As shown, the S21 includes:

[0079] S211: Obtaining the position coordinates of each pixel point corresponding to each image in each image area;

[0080] Specifically, obtaining the position coordinates of the pixel points corresponding to each image in each image area can be understood as recording the position coordinates of all pixel points constituting each image sub-area in a set, where these pixel points include both ink-emitting pixels and non-ink-emitting pixels.

[0081] S212: Obtaining contour information of each of the images according to the position coordinates of each pixel point of each of the images.

[0087] Specifically, filtering out the position coordinates of the pixel points constituting the edge of the image corresponding to the image sub-region can be understood as filtering out the position coordinates of the inking pixel points adjacent to the non-inking pixel points.

[0088] S2122: Obtain contour information of each image according to the position coordinates of each pixel point corresponding to the edge position.

[0089] Specifically, the linear pattern corresponding to the position coordinates of the pixel points at the edge position is used as the contour information of each image, thereby obtaining each image sub-region; other ink-out pixels and non-ink-out pixels in the combined area are used to obtain the actual image of the image; such as hollow circles and solid circles.

[0090] In one embodiment:

[0091] Figure 6 A schematic diagram of the process flow of the image partition processing method provided in this embodiment;

[0092] like Figure 6 As shown, the S3 includes:

[0096] The color information includes key color display and non-key color display.

[0097] Specifically, all color information of the image sub-region is obtained, and the color adjustment curve of the image sub-region is determined; according to the display requirements of each color in the color information, the parameters representing each color in the color adjustment curve are adjusted accordingly; for example, in the image sub-region, there are image regions corresponding to the three colors of yellow, green and blue, among which yellow needs to be highlighted, then the color adjustment curve is used to increase the brightness of the yellow pixel point, and the brightness of the blue and green pixel points is adjusted to the reference curve position (normal display range), so as to realize the highlighting of the yellow in the image sub-region; please refer to Figure 7 , "actual curve" is the color adjustment curve corresponding to the entire target image; if the yellow in the image sub-region needs to be highlighted, the color adjustment curve corresponding to the image sub-region is corrected to obtain a "correction curve"; specifically, the adjustment curve representing blue and green is returned to the reference curve, so that the brightness of blue and green in the image sub-region is reduced, and at the same time, the adjustment curve representing yellow is adjusted to the symmetric plane of the "actual curve" so that the yellow in the image sub-region contrasts with the yellow in other regions; thereby completing the highlighting of the yellow in the image sub-region; the parameter adjustment of color is not limited to brightness adjustment, but can also be other color parameters such as grayscale and saturation, which are not specifically limited here.

[0100] like Figure 8 As shown, the S3 includes:

[0101] S311: Obtaining the image accuracy of each image type for the image to be printed;

[0102] Specifically, the image to be printed can be a bitmap, or a vector image, or a combination of a bitmap and a vector image. The image accuracy displayed by the vector image and the bitmap is different, and the image accuracy displayed by the bitmap is greater than that displayed by the vector image. At the same time, the bitmap and / or vector image also have different display requirements in different areas, that is, different image accuracy.

[0103] S312: Setting a corresponding image accuracy analysis method for the image accuracy as the image processing method.

[0104] Specifically, according to the image accuracy corresponding to each image area, a corresponding image accuracy parsing method is set for each image area to parse the image of the area; thereby obtaining the image accuracy of the actual display that is consistent with each image area; for example, an image area includes area A, area B and area C; among which area A and area B do not need high-precision display, the image data of the area can be parsed according to the image accuracy actually displayed in area A and area B, such as the printing accuracy corresponding to the image data is 720dpi, while the display accuracy of area A and area B only needs 180dpi; then area A and area B are parsed according to 180dpi; thereby improving the parsing speed; and area C is a key display area, which can be parsed according to the actual image accuracy of the image to be printed, such as if the printing accuracy is 720dpi, the actual parsing accuracy is 720dpi, thereby ensuring the quality of the printed image.
