Abstract: An image processing method includes: extracting from the image component images including first and second chroma component images; dividing each component image into component pixel block sets; and defining processing sequences of the component pixel blocks; for a current chroma component pixel block, performing intra mode prediction to obtain intra prediction modes for the current chroma component pixel block. The intra mode prediction method includes: determining an application area including a set of pixels in a pixel block of one of the component images. The pixel block has already been processed according to a respective processing sequence defined for the one of the component images, performing a gradient analysis on a pixel of the application area, selecting, based on results of the gradient analysis, a intra prediction video coding mode among intra prediction video coding modes usable for encoding and/or decoding the current chroma component pixel block.
