Image processing apparatus and control method for the same, and ultrasound imaging apparatus

The present invention, through the speckle energy (Speckle energy) analysis in an ultrasound image signal, and determines the frequency band of the video signal, the multi-band image segmentation of the image processing apparatus, image processing apparatus control method, and an ultrasonic imaging device ( frequency Decomposition) process to obtain an adaptive multi-frequency images according to a video or depth (depth) in a multi frequency band video synthesizer (Compounding) and then, the axis (axial) as to the image decoding axis (axial) resolution reduction in the direction of orientation a describing prevented. An exemplary image processing according to the example device, dividing the image signal on the basis of the larger specification to analyze speckle energy (speckle energy) of the ultrasound image signals received from the ultrasonic probe energy analyzer, an analysis of energy in one or more frequency bands and a picture division to.
