1. An image processing device comprising:
a receiver configured to receive two-dimensional (2D) pixel information;
at least one first line buffer configured to output the 2D pixel information in a line-wise data line;
an operator configured to perform a convolution operation based on the 2D pixel information of the data line; and
at least one second line buffer configured to output a data line obtained by performing the convolution operation
wherein the operator comprises:
a first convolution operator a first convolution operator configured to generate at least one feature map by performing a convolution operation for the data in the data line,
a feature map processor configured to store the at least one feature map as at least one line-wise feature map, and process the stored at least one line-wise feature map to be output in a two or higher dimensional form; and
a second convolution operator configured to perform a convolution operation for the at least one feature map in the two or higher dimensional form.
