According to one embodiment, a semiconductor memory card includes a first and a second pin group used for readingwriting data in a first and a second modes and an interference portion that prevents the semiconductor memory card from being inserted up to a normal position of a card insertion hole of a connector dedicated to the first mode. A sense die mounts on the carrier having a first side configured to interact with a fluid from the vessel. Then, each non-reference image is registered with another one of the images, including the reference image, which exhibits an exposure that is both closer to that of the reference image than the image under consideration and closest among the other images to the exposure of the image under consideration, to generate a flow field.
