The aim of the invention is to enable high-speed signal processing for a measurement apparatus, which performs imaging using adaptive signal processing, and spatial smoothing. The measurement apparatus generates image data inside an object using an analog signal obtained by receiving an ultrasound propagated inside the object with a plurality of ultrasound transducing devices, the measurement apparatus comprising: a received signal processing unit which converts the analog signal to a digital signal； a calculating unit which performs adaptive signal processing on the digital signal and generates image information； and a data reducing unit which reduces data amount of the digital signal transferred from the received signal processing unit to the calculating unit.
