    Abstract: Identification medium recognition device (3) includes image input (11) that acquires a captured image imaged by an imaging device, identification medium region detector (12) that detects a region of the identification medium from the captured image, identification medium recognizer (18) that recognizes the character and/or the numeric character included in the identification medium from the region of the identification medium, super-resolution processor (17) that selectively performs super-resolution processing of the region of the identification medium, region storage (14) that stores a preset region in the captured image, identification medium region determiner (13) that determines whether the region of the identification medium is positioned within the preset region, and super-resolution processing selector (16) that selects, in a case where it is determined that the region of the identification medium is positioned within the preset region, execution of super-resolution processing by the super-resolution processor.

    Abstract: A fluid density gradient detection method includes capturing, by an imaging device under a predetermined imaging condition, a background image that forms a periodic pattern over an observation target area, and outputting an image indicating a fluid density gradient in the observation target area based on a captured image captured by the imaging device. The imaging condition is determined based on a relationship between a width of a pixel of the captured image in a direction in which the pattern periodically changes on the captured image and a pattern period width of the pattern on the captured image.
