Patent ID: 8641616

Claim:
A bio-information processing apparatus comprising: a bio-information sensor that measures bio-information of a subject only in a non-contact manner and in an unrestricted manner, wherein the subject is a viewer of content comprising a video signal and a sound signal reproduced by a reproduction apparatus; a bio-information analysis circuit that estimates a psychological state of the subject and an intensity of the psychological state as a reaction of the subject to the video and sound signals based on at least one measured value of the bio-information measured using the bio-information sensor and based on an initial value or a standard value of the bio-information to generate an estimation result; and a control circuit that, in response to the estimation result, automatically modifies the video signal and/or the sound signal reproduced by the reproduction apparatus by: when the estimation result indicates that the subject is dissatisfied with the video signal and/or the sound signal, a luminance and a contrast of the video signal are decreased while the video signal continues to be reproduced by the reproduction apparatus, and a volume of the sound signal is decreased while the audio signal continues to be reproduced by the reproduction apparatus, and when the estimation result indicates that the subject is interested with the video signal and/or the sound signal, the luminance and the contrast of the video signal are increased and the volume of the sound signal is increased.
