Abstract:
1. A data processing method comprising use of a programmed computer system having a CPU and memory to process acquired signal data representing physical structures or events by: (A) estimating signal power by using reference data containing data similar to processing-target data; and (B) processing the processing-target data by using a wiener function (WF) based on the signal power estimated in the step of (A), wherein when multiple pieces of reference data are acquired, the signal power is determined by weighted averaging of the multiple pieces of reference data, and wherein the signal power is determined by increasing the weighting of the processing-target data with respect to a low-frequency component and by increasing the weighting of either one of the processing-target data and data different from the processing-target data, the either one having a larger SNR of the signal power.
