Image processing method and device and video processor

[0031] like figure 1 As shown, an image processing method disclosed in the first embodiment of the present invention includes:

[0032] The determining step S100 is used to determine the point-by-point transparency of each pixel point in the preset direction according to the start position and end position of the non-masked area of ​​the image to be processed in the preset direction and the number of pixels per clock cycle, wherein the point-by-point transparency of at least one pixel of the image to be processed located outside the non-masked area in the preset direction is determined to be transparent; and

[0033] The masking step S200 is used to apply the point-by-point transparency to the respective pixel points of the image to be processed in the preset direction during image superposition processing.

[0034] Through the above-mentioned steps and methods, the image can be masked in more detail, and any pixel in the preset direction can be masked, so as to realize the effe

[0057] like Figure 4 As shown, an image processing device disclosed in the second embodiment of the present invention includes:

[0058] The determining module 700 is configured to determine the point-by-point transparency of each pixel point in the preset direction according to the start position and end position of the non-masked area of ​​the image to be processed in the preset direction and the number of pixels per clock cycle, The point-by-point transparency of at least one pixel of the image to be processed outside the non-masked area in the preset direction is determined to be transparent. The masking module 900 is configured to apply the point-by-point transparency to the respective pixel points of the image to be processed in the preset direction during image superposition processing.

[0059] Through the above modules, the image can be masked more carefully, and at least one pixel point in the preset direction can be masked. It should be noted that the determining mo

[0070] The third embodiment of the present invention discloses a video processor, including: a programmable logic device. The programmable logic device is, for example, FPGA, which is used to determine the step by step of each pixel in the preset direction according to the start position and end position of the non-masked area of ​​the image to be processed in the preset direction and the number of pixels per clock cycle. point transparency, and apply the point-by-point transparency to each pixel point of the image to be processed in the preset direction to perform mask processing to cover the image to be processed located at the preset direction in the at least one pixel outside the non-masked area.

[0071] In addition, the programmable logic device is also used to apply the point-by-point transparency to each pixel point of the image to be processed in the preset direction to perform mask processing, for example, apply the point-by-point transparency in the image superposition
