US 2009/0257589 A1 · MONITORING CAMERA SYSTEM, IMAGING DEVICE, AND VIDEO DISPLAY DEVICE

Abstract

An imaging device (1) for imaging a subject and distributing the captured video. The privacy of the subject is adequately protected, and a required monitoring function is realized. The imaging device (1) comprises an imaging section (10) for imaging a subject, an encryption key list storage section (13) storing encryption key data associated with a video display device and permitting display of the captured video showing the subject for each subject, a communication section (12) for judging whether or not a specific subject corresponding to the video display device is shown in the captured video, a video encrypting section (15) for encrypting a partial video of at least the specific subject in the captured video with encryption key data associated with video display device specifying information on the specific subject when the communication section (12) has judged that the specific subject is shown in the captured image, thereby to convert the partial video into an encrypted video, and create a limited captured video including the encrypted video, and a video transmitting section (16) for distributing the limited captured video to the video display device.

Dependent claims

A monitoring camera system comprising an imaging device which captures one or more objects and distributes captured video and a video display device which receives and displays the captured video,

wherein said imaging device includes:
a capturing unit operable to capture an object;
an encryption key storage unit in which encryption key data is stored for each object, the encryption key data being associated with a video display device that is permitted to display the captured video in which the object is included;
an object judging unit operable to judge whether or not a specific object, which is an object associated with said video display device, is included in the captured video;
a limited-capture video generation unit operable to convert at least a part showing the specific object in the captured video into encrypted video by encrypting the part using the encryption key data which is associated with said video display device and is stored for the specific object, and to generate limited-capture video which includes the encrypted video, when said object judging unit judges that the specific object is included;
and
a video distribution unit operable to distribute the limited-capture video to said video display device, and
said video display device includes:
a reception unit operable to receive the limited-capture video;
a decryption key storage unit operable to store decryption key data which is associated with said video display device;
and
a video decryption unit operable to generate decrypted video by decrypting the encrypted video included in the limited-capture video using the decryption key data.

An imaging device which captures one or more objects and distributes captured video, comprising:

a capturing unit operable to capture an object;
an encryption key storage unit which encryption key data is stored for each object, the encryption key data being associated with a video display device that is permitted to display the captured video in which the object is included;
an object judging unit operable to judge whether or not a specific object, which is an object associated with the video display device, is included in the captured video;
a limited-capture video generation unit operable to convert at least a part showing the specific object in the captured video into encrypted video by encrypting the part using the encryption key data which is associated with the video display device and is stored for the specific object, and to generate limited-capture video which includes the encrypted video, when said object judging unit judges that the specific object is included;
and
a video distribution unit operable to distribute the limited-capture video to the video display device.

3 more elements

A distribution device which distributes, to a video display device, captured video captured by an imaging device, said distribution device comprising:

an encryption key storage unit in which encryption key data is stored for each object, the encryption key data being associated with a video display device that is permitted to display the captured video in which the object is included;
an object judging unit operable to judge whether or not a specific object, which is an object associated with the video display device, is included in the captured video;
a limited-capture video generation unit operable to convert at least a part showing the specific object in the captured video into encrypted video by encrypting the part using the encryption key data which is associated with the video display device and is stored for the specific object, and to generate the limited-capture video including the encrypted video, when said object judging unit judges that the specific object is included;
and
a video distribution unit operable to distribute the limited-capture video to the video display device.
