Zusammenfassung:The invention discloses a method and device for scaling a native image, a medium and electronic equipment, and the method comprises the steps: carrying out the interpolation processing of a plurality of channels of the native image, and obtaining full-resolution images corresponding to the channels respectively; wherein the full-resolution image corresponding to any channel comprises a pixel value, corresponding to the channel, of each pixel point in the original image; determining the scaling of the original image; according to a scaling ratio, carrying out scaling processing on the full-resolution images respectively corresponding to the plurality of channels to obtain scaled images respectively corresponding to the plurality of channels; and according to a data arrangement rule of the original image, sampling the scaled images corresponding to the plurality of channels to obtain a scaled image corresponding to the original image. According to the method and the device, the original image can be scaled acco
