Processor and method for scaling image

A method for scaling an image, comprising:

• receiving an image scaling instruction, the image scaling instruction including a width scaling factor and a height scaling factor, a to-be-scaled original image being an N-channel image, N being an integer greater than 1;
• executing the image scaling instruction, and sending a calculation control signal for calculating pixel data of each target pixel in a scaled target image to an array processor;
• and
• controlling the array processor to extract pixel data of a pixel in the original image corresponding to a target pixel using the calculation control signal, and controlling N processing elements in the array processor to calculate in parallel channel values of N channels in the target pixel based on the width scaling factor, the height scaling factor, and channel values of N channels in the extracted pixel data,
• wherein the method is performed by at least one hardware processor.

A device, comprising:

• a processor;
• and
• a memory,
• the memory storing computer readable instructions executable by the processor and causing the processor to execute a method for scaling an image, the method comprising:
• receiving an image scaling instruction, the image scaling instruction including a width scaling factor and a height scaling factor, a to-be-scaled original image being an N-channel image, N being an integer greater than 1;
• executing the image scaling instruction, and sending a calculation control signal for calculating pixel data of each target pixel in a scaled target image to an array processor;
