Abstract
Based on at least one of a degree of variation in brightness values of pixels or a representative brightness value of frame data for evaluation range decision for each region defined in a data space of frame data, each region is classified into a region that is included in an evaluation range and a region that is not included in the evaluation range. An attenuation amount estimation unit estimates an attenuation amount of ultrasound waves in a subject based on a frequency spectrum of reception beam data of each region included in the evaluation range among a plurality of regions arranged in a depth direction, the region being defined in a data space of the reception beam data and corresponding to each region defined in the data space of the frame data. An image formation unit executes TGC processing as brightness correction processing based on the attenuation amount of the ultrasound waves estimated by the attenuation amount estimation unit.
