摘要：
A brain activity estimation device (10) includes an image data acquisition means (20) and a brain activity estimation means (30). The image data acquisition means (20) acquires photographed image data on a facial surface of a human in time series. The brain activity estimation means (30) includes an RGB processing unit (31), a blood-circulation-amount calculating unit (33), and an estimation unit (35). The RGB processing unit (31) conducts RGB processing on the photographed image data acquired by the image data acquisition means (20) to decompose the photographed image data into three color components composed of an R component, a G component, and a B component. The blood-circulation-amount calculating unit (33) calculates time-series blood-circulation-amount data on the facial surface, based on the RGB data of the photographed image data obtained by the RGB processing. The estimation unit (35) estimates brain activity of the human based on a plurality of components obtained by decomposing the blood-circulation-amount data by singular value decomposition, principal component analysis, or independent component analysis.
