Abstract: A travel map generation device includes: a sensor that obtains a positional relationship between the travel map generation device and an object in a vicinity thereof and processing circuitry (a controller). The processing circuitry (the controller): calculates, based on the positional relationship, a self position on a floor map representing a predetermined floor; obtains an image including reflected light produced by light emitted from a light emission device operated by a user; and generates, based on the self position and the image, information indicating an entry prohibited area into which an autonomously traveling robot is prohibited from entering, or a travel area for the autonomously traveling robot, in the floor map.

Abstract: In an imaging device, a difference calculation unit calculates a differential signal between charge signals that have been accumulated and are held by first and charge holding units with different timings. A multiple sampling unit performs multiple sampling processing on the differential signal, and an analog digital conversion unit converts a signal that has undergone multiple sampling processing to a digital signal. That is, multiple sampling processing is performed on a differential signal with a higher sparsity than that of an image signal.
