It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of the present invention described here can be implemented in an order different from those illustrated or described here.

[0044] Example 1

[0045] Figure 1 The following is a flowchart of an inkjet printing method provided by the first embodiment of the present invention. This embodiment is applicable to the case of uniformly sampling points at the edge of an inkjet image to be printed. The inkjet printing method can be executed by an inkjet printing device, which can be implemented in the form of hardware and / or software, and the inkjet printing device can be configured in an electronic device available for inkjet printing. As Figure 1 shown, the inkjet printing method includes:

[0046] S110. Generate an inkjet sample image corresponding to the initial inkjet image to be printed, and determine a first pixel interval distance between uniform sampling regions according to the inkjet sample image.

[0047] Among them, the initial inkjet image to be printed is the original image that needs to be inkjet printed. The initial inkjet image to be printed can be collected by an electronic device for inkjet printing. In this embodiment, no specific restrictions are imposed on the specific image type of the initial inkjet image to be printed.

[0048] Specifically, perform binarization processing on the initial inkjet image to be printed, and the image after binarization is the inkjet sample image. The gray value of the pixel points on the inkjet sample image is set to 0 or 255, presenting an obvious black and white effect.

[0049] In this embodiment, count the second pixel interval distance from each pixel point with a pixel value of 0 in the inkjet sample image to the adjacent pixel point with a non-0 pixel value. The second pixel interval distance from a pixel point with a pixel value of 0 to the adjacent pixel point with a non-0 pixel value can be denoted as distanceOne, distanceTwo, distanceThree... Further, the shortest distance distanceMin = Min(distanceOne, distanceTwo, distanceThree...) in the second pixel interval distance can be used as the first pixel interval distance between the uniform sampling regions.

[0050] It can be known that the first pixel interval distance is the interval distance for dividing the uniform sampling regions. The first pixel interval distance can be determined by selecting the shortest distance from the above pixel intervals, or can be selected and set by those skilled in the art according to experience. This embodiment does not impose special restrictions on this.

[0051] S120. Determine at least two uniform sampling regions according to the first pixel interval distance, and select sampling pixel points at a set distance in the uniform sampling regions for sampling to obtain an inkjet target image for printing the inkjet target image.

[0052] Specifically, the inkjet sample image is divided into at least two evenly sampled areas based on the first pixel interval distance. Considering the image uniformity, the inkjet sample image is repeatedly divided by the first pixel interval distance to divide the inkjet sample image into multiple evenly sampled areas.

[0053] In one embodiment, the first pixel interval distance is used as the interval distance for dividing each evenly sampled area, and at least two evenly sampled areas are divided, that is, the evenly sampled areas are divided at equal distances.

[0054] In another embodiment, after one evenly sampled area can be divided on the pixel sample image with the first pixel interval distance, the inkjet sample image except for this evenly sampled area is used again. The third pixel interval distance from each pixel point with a pixel value of 0 to the adjacent pixel point with a non-0 pixel value is calculated in the inkjet sample image except for this evenly sampled area, and then the next evenly sampled area is further divided according to the third pixel interval distance, and so on, to complete the division of the evenly sampled areas of the inkjet sample image.

[0055] Exemplarily, taking the evenly sampled area including the first sampled area, the second sampled area, and the third sampled area as an example, the first sampled area is determined according to the first pixel interval distance, the third pixel interval distance is determined according to the inkjet sample image except for the first sampled area, and the second sampled area and the third sampled area are determined according to the third pixel interval distance.

[0056] On the above basis, after selecting a sampling pixel point in the evenly sampled area, another sampling pixel point is selected outside the circle with the sampling pixel point as the center and the set distance as the radius, and so on, sampling is performed in the evenly sampled area to obtain the inkjet target image.

[0057] It should be noted that the sampling pixel points can be selected one by one in the evenly sampled area according to the set distance for sampling to obtain the inkjet target image, or the sampling pixel points can be selected simultaneously in each evenly sampled area according to the set distance for sampling to obtain the inkjet target image.

[0058] The technical solution of the embodiment of the present invention generates an inkjet sample image corresponding to the initial inkjet image to be printed, and determines the first pixel interval distance between the evenly sampled areas according to the inkjet sample image; at least two evenly sampled areas are determined according to the first pixel interval distance, and sampling pixel points are selected for sampling in the evenly sampled area according to the set distance to obtain the inkjet target image for printing the inkjet target image. The present invention solves the problem that in current inkjet printing, it is impossible to ensure that the edges of the printed image or text are smooth and uniform, without obvious burrs or dotted lines, realizes uniform sampling of the edges of the inkjet printed image, ensures the printing effect, and meets the printing user requirements.

[0059] Example Two

[0060] Figure 2 The figure is a flowchart of an inkjet printing method provided by the second embodiment of the present invention. On the basis of the above embodiment, the shortest distance in the second pixel interval distance is used as the first pixel interval distance between the uniform sampling regions, and an optional implementation manner is provided. As Figure 2 shown, the inkjet printing method includes:

[0061] S210. Generate an inkjet sample image corresponding to the to-be-printed inkjet initial image, and determine the second pixel interval distance from each pixel point with a 0 pixel value on the inkjet sample image to the adjacent pixel point with a non-0 pixel value.

[0062] Refer to Figure 3 shown, the edges of the to-be-printed inkjet initial image are uneven and non-uniform. In order to make its image edges smooth and uniform, the technical solution of this embodiment is adopted to process it.

[0063] S220. Use the shortest distance in the second pixel interval distance as the first pixel interval distance between the uniform sampling regions.

[0064] S230. Use the first pixel interval distance as the regional division interval distance for each uniform sampling region, and divide at least two uniform sampling regions.

[0065] Refer to Figure 4 shown. Using the first pixel interval distance as the regional division interval distance for each uniform sampling region, that is, dividing four uniform sampling regions at equal interval distances. It can be known that multiple uniform sampling regions can also be divided with the first pixel interval distance. This embodiment does not impose any restrictions on the number of uniform sampling regions divided for the specific pixel sample image.

[0066] S240. Select sampling pixel points at a set distance in the uniform sampling regions for sampling to obtain an inkjet target image for printing the inkjet target image.

[0067] Exemplarily, the sampling pixel points can be pixel points with a 0 pixel value, or any pixel points can be selected. This embodiment does not impose any restrictions on this.

[0068] Specifically, after arbitrarily selecting a sampling pixel point in the uniform sampling region, then use the sampling pixel point as the center of the circle and select the next sampling pixel point outside the radius with the set distance. The next sampling pixel point can also be a pixel point with a 0 pixel value, or any pixel point can be selected. And so on, sampling is carried out in the uniform sampling region until no sampling pixel point can be selected in the pixel sample image, or the selection of the set number of sampling pixel points has been completed, then the corresponding inkjet target image is generated.

[0069] It is known that the set number of sampled pixel points can be selected and set by those skilled in the art according to the actual printing effect display requirements, and there is no special limitation on the set number of sampled pixel points.

[0070] In the technical solution of the embodiment of the present invention, with the first pixel interval distance as the interval distance for dividing each uniform sampling area, at least two uniform sampling areas are divided, and sampling pixel points are selected at a set distance in the uniform sampling area for sampling to obtain an inkjet target image for printing the inkjet target image, which can not only increase the stability and display effect of the image, improve the printing effect and stability, but also provide better support for advanced printing controls such as sampling.
