1. An image processing device, comprising:
a data group generator configured to:
receive pixel values including phase information and brightness information of an image from a device external to the image processing device; and
determine data groups based on target pixel values, wherein the data groups correspond to a range that is determined according to the phase information;
a gradient value manager configured to:
determine gradient values of a region corresponding to the target pixel values; and
determine gradient information by applying threshold values to the gradient values, wherein the threshold values are determined according to the target pixel values; and
a cost volume manager configured to determine a cost volume by weighted summing the data groups based on the gradient information.
