1. 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, andwhen 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.

Abstract
A bio-information processing apparatus includes a bio-information sensor for measuring the bio-information of a subject in a non-contact manner and in an unrestricted manner; and a circuit for estimating the psychological state of the subject and the intensity thereof on the basis of the measured value of the bio-information measured using the bio-information sensor and on the basis of an initial value or a standard value of the measured value.

16. A reproduction apparatus comprising:
-
a reproduction section that reproduces a video signal and a sound signal; a bio-information sensor that measures bio-information of a viewer of content comprising the video signal and the sound signal reproduced by the reproduction section only in a non-contact manner and in an unrestricted manner; a bio-information analysis circuit that estimates a psychological state of the viewer and an intensity of the psychological state 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 device operable to; cause the video signal and/or the sound signal reproduced by the reproduction section to be automatically modified in response to the estimation result of the bio-information analysis circuit; when the estimation result indicates that the viewer is dissatisfied with the video signal and/or the sound signal, decrease a luminance and a contrast of the video signal while the video signal continues to be reproduced by the reproduction apparatus and decrease a volume of the sound signal while the audio signal continues to be reproduced by the reproduction apparatus; and when the estimation result indicates that the viewer is interested with the video signal and/or the sound signal, increase the luminance and the contrast of the video signal and increase the volume of the sound signal. - View Dependent Claims (19)
