A video processor receives first and second images respectively acquired by an endoscope at first and second timings before and after a predetermined function is applied to a subject, generates first and second correction images respectively using first and second images, generates first and second post-correction images respectively obtained by causing the first and second correction images to act on the first and second images, extracts color components in the second post-correction image to find first and second distribution characteristic values, and calculates a degree of change of the second distribution characteristic value from the first distribution characteristic value.

Image analysis apparatus, image analysis system, and method for operating image analysis apparatus

An image analysis apparatus includes a processor including hardware. The processor extracts parts from each of a first image and a second image acquired after the first image, each of the extracted parts including an annular peripheral portion and a central portion having a color different from a color of the peripheral portion. The processor also sets the central portion as the analysis object region and calculates a brightness decrease degree of the analysis object region in the second image relative to the analysis object region in the first image.

To provide an aircraft strength testing apparatus that, using a curved specimen, can produce a desired stress safely and quickly by reliably applying an internal pressure, and moreover allows any resulting damage to be reliably observed. A testing apparatusthat applies an internal pressure, equivalent to a differential pressure between the outside and the inside of a section to be tested of a fuselage of an aircraft, to a curved specimencorresponding to the section to be tested, includes: a pressure vesselbetween which and the specimena cavityis formed; and rodsthat restrain the specimenagainst the internal pressure. The pressure vesselfaces the outer side of the specimen. By reducing the pressure inside the cavity, an internal pressure is applied to the specimen

In an approach for testing the operations of a host system during a host system migration, a terminal agent exchanges messages already exchanged between the current host system and a terminal with the new host system. A manual operation replay unit replays messages generated by manual operations among the messages sent to the current host system by the terminal. An automatic response unit automatically generates a response message for messages received from the new host system. The automatic response unit also generates screen data for a screen displayed on the terminal on the basis of messages received from the new host system. A comparison unit compares and evaluates screen data generated by the automatic response unit and screen data from a screen generated by the terminal on the basis of messages received from the current host system.
