Abstract: An image processing device includes an estimator (54) configured to estimate a degree of fogging of image data on the basis of the image data, the image data having been acquired by an imaging device (41) capturing an image of an imaging target (T) disposed in a casing (25) of an air treatment device (10); and a determiner (55) configured to determine output image data on the basis of the degree of fogging of the image data estimated by the estimator (54), the output image data being image data to be output.

Abstract: A camera (26) takes an image of at least one user (U1, U2, U3). A room environment information sensor (13) senses room environment information relating to an environment of a room (r1) in which the at least one user (U1, U2, U3) is present. The estimator (66) estimates a drowsiness condition of the at least one user (U1, U2, U3) based on the image of the at least one user (U1, U2, U3) taken by the camera (26) and the room environment information sensed by the room environment information sensor (13).

Abstract: A body of a casing is provided with a predetermined component. An imaging device includes an attachment portion detachably attached to the component so as to be at a position at which the imaging device can image the at least one predetermined object to be imaged.

Abstract: A drainage mechanism is connected to a drain pump that sucks water from a drain pan. The drainage mechanism includes a connecting part that connects to the drain pump, a first flow path, a folded part, and a second flow path. The first flow path extends upward from the connecting part. The folded part has a first end connected to an upper end of the first flow path and a second end on a side opposite to the first end. The folded part changes a direction of the water flowing therein from upward to downward. The second flow path extends from the second end. The second flow path is a pipe that has an inner diameter of 13 mm or less. The flow path area of the folded part is larger than the flow path area of the second flow path.

Abstract: An air treatment device includes a casing, a drain pan provided in the casing, a camera configured to capture an inner surface of the drain pan to obtain image data, and a lighting device configured to apply, to a photographing target of the camera, visible light having a maximum peak wavelength in a wavelength band from 400 nm to 500 nm.

Abstract: A camera takes an image of a user. A room environment information sensor detects room environment information about an environment in a room where the user is present. An estimation unit estimates a concentration degree of the user based on the image of the user taken by the camera and the room environment information sensed by the room environment information sensor.

Abstract: An imaging target includes a light emitter configured to emit visible light from a surface of the imaging target, and an imaging device captures an image of at least the light emitter of the imaging target and acquires image data including the light emitter.

Abstract: An estimation unit estimates a thermal sensation representing how hot or cold a user feels based on an image of the user taken by a camera. A control unit controls an air-conditioning operation of an air conditioner based on an estimation result of the estimation unit so that the thermal sensation falls within a target range, the air conditioner targeting a room in which the user is present. The image shows a motion and/or state of the user representing a hot or cold sensation of the user, and the estimation unit extracts the motion and/or state of the user from the image to estimate the thermal sensation.

The air-conditioning device includes a control unit that makes an imaging device capture an image while at least one predetermined component of the air-conditioning device is at rest.

Abstract: An air conditioning system includes an air conditioner, a detector, a transmitter, and a control unit. The air conditioner includes an indoor unit. The detector detects a user action toward the indoor unit. The transmitter transmits first information on the indoor unit to a terminal of the user. The control unit causes the transmitter to transmit the first information to the terminal when the detector detects the user action.

Abstract: An air conditioning control system includes an air conditioner, a setting unit, a control unit and a learning unit. The air conditioner performs air conditioning in a room. The setting unit sets a first temperature and a second temperature. The first temperature is a target temperature for a first area in the room. The second temperature is a target temperature for a second area in the room. The control unit controls the air conditioner so that a temperature of the first area approaches the first temperature and a temperature of the second area approaches the second temperature. The learning unit learns control of the air conditioner so that the temperature of the first area approaches the first temperature and the temperature of the second area approaches the second temperature.

Abstract: An air flow control apparatus controls a fan. The air flow control apparatus includes an acquisition section, a detection section, and a control section. The acquisition section acquires image data obtained by an image capturing device installed in a target space. The detection section detects a specific object movable by an air flow sent from the fan, based on the image data acquired by the acquisition section. The control section executes first processing. The first processing includes controlling at least one of a direction and a volume of an air flow sent from the fan, based on a result of detection by the detection section.

Abstract: A ventilation device control apparatus includes an image acquisition unit, a first calculation unit, and a ventilation control unit. The image acquisition unit acquires a captured image from an image capturing device that captures an image of a target space. The first calculation unit calculates a metabolic rate equivalent amount of a person in the target space, based on the captured image acquired by the image acquisition unit. The ventilation control unit adjusts a ventilation volume of the target space by a ventilation device that ventilates the target space, based on the metabolic rate equivalent amount calculated by the first calculation unit. A ventilation system further includes the image capturing device and the ventilation device.
