Abstract: The display device includes a mirror display element, a display, an optical element array, an external light reflection suppression layer, and a driving unit. The mirror display element reflects a part of external light and transmits a part of the external light. A display is disposed on an opposite side of an outer surface of the mirror display element, in which a plurality of pixels are two-dimensionally arranged. An optical element array is disposed between the mirror display element and the display in parallel with a light emission surface of the display, in which a plurality of optical elements corresponding to a predetermined unit of pixels among the plurality of pixels are arranged. An external light reflection suppression layer is disposed between the mirror display element and the display to suppress reflection of the external light. The driving unit drives the display to turn on a predetermined pixel among the plurality of pixels.

Abstract: A mounting machine includes a first imaging unit that captures, as a first captured image, a first imaging region in a predetermined imaging region on a substrate illuminated with laser light, the first imaging region being smaller than the predetermined imaging region, a second imaging unit that captures, as a second captured image, a second imaging region in the predetermined imaging region, the second imaging region smaller than the predetermined imaging region and including at least a region different from the first imaging region, and a calculation unit that detects an illumination position of the laser light from at least one captured image of the first captured image or the second captured image, and calculates a height of the substrate based on the detected illumination position.
