Embodiment Construction

[0047] Before describing the embodiment of the present invention, first, the idea of ​​the present inventor that was an important basis when the present inventor made the present invention will be described.

[0048] (1) Points of thought of the present inventor

[0049] It is known that human intellectual activities (cognitive activities, etc.) and emotional activities (pleasure / displeasure, etc.) are reflected in human brain activities. Furthermore, conventionally, attempts have been made to estimate human brain activity, but at this time, data detected by any of electroencephalogram measurement, magnetic resonance imaging, and near-infrared spectroscopy are often used.

[0050] Here, as a detection method, for example, in the case of employing electroencephalogram measurement, it is necessary to attach electroencephalogram electrodes to the person to be measured. Furthermore, since it is necessary to reduce the resistance between the skin and the electrode when attaching t...

Abstract

A brain-activity estimation device (10) is provided with: an image-data acquiring means (20); and a brain-activity estimating means (30). The image-data acquiring means (20) acquires captured-image data of a human face time sequentially. The brain-activity estimating means (30) includes: an RGB processing unit (31); a blood-circulation-level calculating unit (33); and an estimating unit (35). TheRGB processing unit (31) applies RGB processing to the captured-image data acquired by the image-data acquiring means (20), thus decomposing the captured-image data into three color components, namely, an R-component, a G-component, and a B-component. The blood-circulation-level calculating unit (33) calculates, time sequentially, blood-circulation-level data of the face on the basis of the RGB data of the captured-image data obtained by means of the RGB processing. The estimating unit (35) estimates human brain activity on the basis of multiple components obtained by decomposing the blood-circulation-level data by means of singular value decomposition, principal component analysis, or independent component analysis.

Description

technical field [0001] The present invention relates to a brain activity estimation device for estimating human brain activity. Background technique [0002] Conventionally, attempts have been made to use electroencephalogram measurement (EEG), magnetic resonance imaging (fMRI: functional Magnetic Resonance Imaging), or near-infrared spectroscopy ( NIRS) to estimate human brain activity. Contents of the invention [0003] The problem to be solved by the invention [0004] However, when electroencephalogram measurement or near-infrared spectroscopy is used as a detection method, it is necessary to attach electrodes and probes that require pretreatment to the person to be measured. In addition, when magnetic resonance imaging is used as a detection method, it cannot be measured unless it is in the MRI room. That is, in the case of detecting data using any of the electroencephalogram measurement method, magnetic resonance imaging method, and near-infrared spectroscopy, the...
