Image processing method and device

The invention provides an image processing method and device. The method comprises the following steps: acquiring image data; the first processing unit and the second processing unit are used for calculating filtering weight coefficients of the image data, and the filtering weight coefficients of the image data comprise the filtering weight coefficients corresponding to the first data elements and the filtering weight coefficients corresponding to the second data elements; the filtering weight coefficient corresponding to the first data element and the filtering weight coefficient corresponding to the second data element comprise a first part with the same value and a second part with different values, the first part is calculated by a first processing unit, the second part is calculated by a second processing unit, the first processing unit is a vector processor, and the second processing unit is a vector processor. The second processing unit is a vector processor or a scalar processor. According to the inve
