An image processing method comprising: receiving an image; 5 outputting the image to be image lines of a line unit through at least one first line buffer; generating at least one feature map by performing a first convolution operation based on the output image lines; storing the at least one feature map into at least one line unit, and processing the 10 at least one generated feature map to output the at least one feature map stored in the line unit to be in a two-dimensional (2D) form; and performing a second convolution operation on the feature map output in the 2D form.
