Abstract: To provide a device, system, and program with which it is possible for photometric information or colorimetric information corresponding to an international industry standard to be accurately measured in a simple manner. In one embodiment, a measurement apparatus (1) includes: an imaging unit (11) that acquires image data of an image; converters (141, 142) that use image data shooting information to convert the image data into data including photometric information or colorimetric information; and an output unit (16) that outputs the photometric information or the colorimetric information obtained by the converters.

Abstract: To provide an apparatus, a system, and a program that can easily detect an image region where retroreflected light is recorded without being influenced by a neighboring object. In one embodiment, a measuring apparatus (1) includes an imaging unit (11), a converter (141) that converts first image data captured by the imaging unit using light emission for photography and second image data captured by the imaging unit without using the light emission for photography to luminance values, a differential processor (142) that calculates a difference between a first luminance value based on the first image data and a second luminance value based on the second image data for each pixel and generates an output image visually representing a region where the difference is present based on an obtained differential image, and a display unit (16) that displays the output image.
