When I try to specify the img-size to 1280, the output image is darker than the input image.

@wilile26811249 Yeah, that's because of the saliency map. At points in which no activation occurred, it's a dark layer. Also, for better visualization, a normalization operation is performed, resulting in a darker image.

Thank you for your explain. I understand.
