Image generation method and image processing system

An image processing system, comprising:

• a storage device, configured to store a plurality of image processing models and a plurality of training data sets;
• and
• a processor, coupled to the storage device,
• wherein the processor is configured to:
• establish a plurality of image processing models, wherein the plurality of image processing models respectively correspond to a plurality of candidate image sizes;
• obtain the plurality of training data sets, wherein the plurality of training data sets respectively correspond to the plurality of candidate image sizes;
• use the plurality of training data sets to train the plurality of image processing models respectively;
• detect a first image size of an input image, wherein the input image is a two-dimensional image;
• determine a target image processing model from the plurality of image processing models according to the first image size;
• process the input image through the target image processing model to generate depth information corresponding to the input image;
• and
• generate a first output image and a second output image according to the depth information, wherein the first output image and the second output image are utilized to form a three-dimensional image corresponding to the input image.
