Image processing device and image processing method

Abstract

An image processing device performs a filtering operation on image data according to a set of filter data, and includes a data reconstruction circuit, a memory and an intelligent processor. The data reconstruction circuit reconstructs data of blocks in the image data to generate first reconstruction data, and reconstructs the set of filter data to generate second reconstruction data. The memory stores the first reconstruction data and the second reconstruction data. The intelligent processor executes a depthwise convolution operation according to the first reconstruction data and the second reconstruction data to generate feature map data. Two adjacent of the multiple blocks have partially same data, and quantities of columns in the second reconstruction data are associated with a channel count of the depthwise convolution operation.
