Abstract: An ultrasonic testing method is provided to measure a thickness of an object in a simple and highly accurate manner when crystal grains that form a metal solidification structure of a directionally-solidified material cast or the like have a statistical variation.

Abstract: A bit rate converter for converting a first encoded animation image data to a second animation image data, having a different bit rate. The converter stores an assessment value indicating the importance level within each reproduction time interval with respect to the first animation image data. Second animation image data is generated by arithmetically determining the bit rate of the second animation image data on the basis of the bit rate information on the first animation image data and the assessment value indicating the importance level within a preselected time interval with respect to the first animation image data. Accordingly, a larger amount of code is preferentially allocated to the time interval having an assessment value of higher importance level.

Abstract: In the ultrasonic inspection method and equipment, a high-resolution and high-S/N-ratio inspection image can be speedily acquired with ease-of-operability. Inspection of the inside of the inspection target is performed by changing incident angle of the ultrasonic wave oscillated from the array-probe ultrasonic sensor. Then, while performing the inspection, the array-probe ultrasonic sensor is sequentially displaced from the position to the position via the position by using the displacement member. This displacement allows acquisition of inspection images on each position basis. Finally, the inspection images thus acquired are visualized as a processed image by adding or averaging the inspection images by shifting the images by displacement quantity of the array-probe ultrasonic sensor.
