Abstract: A face detection device and method are provided. The face detection device receives captured images from a camera, and extracts vital information from a face region included in the captured images. The face detection device determines, based on the vital information, whether or not a face included in the face region is in a living state, and collates a feature quantity of the face included in the face region with information of a face which is previously registered. The face detection device selects, according to a user input, whether or not to perform at least one or both of a process for the determining, and a process for the collating.

Abstract: A biological information processing device and method includes selecting image ranges of processing targets from input image data, estimating pulse rates of the processing targets corresponding to the image ranges on the basis of image data of the selected image ranges of the processing targets, performing relative comparison between the estimated pulse rates of the processing targets and thus detecting a target which will possibly be abnormal or a target requiring special attention, and outputting information regarding the detected target which will possibly be abnormal or the detected target requiring special attention.

Abstract: A biological information extracting device which is provided at a head-mounted member mounted on a head of a person (subject) and includes a camera that captures temporally successive images including at least a part of a face of the person as an object; a region selector that selects a skin color region from the image captured by the camera; a pulse wave measurer that measures a pulse wave signal of the person based on image data of the skin color region; and a data transmitter that transmits the pulse wave signal to a predetermined transmission destination. The camera is disposed to face a side surface of the face of the person and is set to capture a part (cheek of the face) of the side surface of the face.

Abstract: A pulse can be stably estimated based on an image data suitable for extracting a pulse signal. A pulse estimation device includes image input portion (21) to which time-sequential captured images including at least a portion of subject H as an object are input from camera (2); region extractor (22) that extracts a skin-color region from each of the captured images; zoom commander (28) that transmits a zoom command to camera (2) that has imaged the captured images or a user of camera (2) in order to adjust a size of the skin-color region; and pulse estimator (23) that estimates a pulse of subject H based on the skin-color region of the captured images obtained by imaging with camera (2), after the zoom command is transmitted.

Abstract: Face detection device that detects a face from an image including a person. The device includes a processor and a memory including instructions that, when executed by the processor, cause the processor to perform operations including: receiving captured images by a camera, detecting one face region or more in the captured images, extracting vital information which includes an index indicating a living state of a face imaged in the face region, based on image data regarding the detected face region; and determining whether or not the face in the face region is in a living state, based on the vital information. The face region detector recognizes a face region corresponding to the face which is determined to be in the living state by the vitality determiner among the one face region or more, as a face region based on a living body.

Abstract: A biological information processing device includes an image input unit that inputs image data, a selection unit, an estimation unit, a detection unit, and an output unit. The selection unit selects image ranges of processing targets from the input image data. The estimation unit estimates pulse rates of the processing targets corresponding to the image ranges on the basis of image data of the selected image ranges of the processing targets. The detection unit performs relative comparison between the estimated pulse rates of the processing targets and thus detects a target which will possibly be abnormal or a target requiring special attention. The output unit outputs information regarding the detected target which will possibly be abnormal or the detected target requiring special attention.
