Abstract
An image processing method includes an image encoding step of encoding data in which one channel in each pixel of image data including a plurality of pixels is configured by 2 bits or more into data in which the one channel is configured by 1 bit, a transfer step of transferring the encoded data to a printing apparatus, and an image decoding step of decoding the encoded data using the printing apparatus, in which, in the image encoding step, flag information indicating whether the pixel is a character or a line image or a photograph is assigned, and in the image decoding step, decoding is performed by selecting a first decoding method or a second decoding method based on the flag information.
