Methods and apparatus to capture images

A method to compile media exposure data from a plurality of media exposure environments, the method comprising:

• obtaining content identifying data from an audience measurement device at a first media exposure environment, the content identifying data corresponding to media content presented by a television within the first media exposure environment, the content identifying data based on an audio signature of the media content, the audio signature generated by the audience measurement device at the first media exposure environment;
• obtaining first exposure information including an identifier associated with a first person, the first exposure information indicative of exposure of the first person to the media content within the first media exposure environment, the first exposure information based on a match of a head present in an image of the first media exposure environment to the first person, the image collected by a camera, the camera in communication with the audience measurement device in the first media exposure environment, the first person registered with an audience measurement entity as associated with the first media exposure environment;
• and
• compiling, by executing an instruction with processor circuitry, the first exposure information with second exposure information from a second media exposure environment, the second exposure information indicative of exposure of a second person in the second media exposure environment to the media content.

An electronic system to compile media exposure data from a plurality of media exposure environments, the electronic system comprising:

• network interface circuitry to obtain the media exposure data, the media exposure data based on:
• respective content identifying data corresponding to media content presented by televisions within respective ones of the plurality of media exposure environments, the respective content identifying data determined based on audio signatures of the media content, the audio signatures generated by respective audience measurement devices;
• and
• respective audience identification information, the audience identification information respectively based on matches between one or more heads detected by corresponding ones of the audience measurement devices in images of corresponding ones of the respective media exposure environments and one or more known persons respectively associated with the media exposure environments;
• computer executable instructions;
• and
• processor circuitry to execute the computer executable instructions to compile the obtained media exposure data for the plurality of media exposure environments, the compiled media exposure data indicating demographics of persons that were exposed to the media content.
