An ultrasonic image processing apparatus includes pixels arranged in a first axis direction corresponding to a scanning direction of an ultrasonic wave transmitted to an object and a second axis direction corresponding to a distance direction in which the ultrasonic wave propagates. Each of the pixels has coordinates based on a reflection position of the ultrasonic wave and a pixel value based on a strength of a reflected wave of the ultrasonic wave. The ultrasonic image processing apparatus includes: a speckle pattern reduction processor setting a size of a filter according to a coordinate on the second axis of a pixel of interest included in the ultrasonic image and performing filter processing using the filter to reduce a speckle pattern in the pixel of interest and an edge information calculator calculating edge information for the pixel of interest in which the speckle pattern has been reduced.
