Abstract
An image captured by a camera can be sent to and stored in a controller on a LAN as well as to a high-capacity camera with more memory than other camera devices on the LAN and to a camera on another LAN. This allows captured images to be recorded without losing the images even if an irregular event is detected and an irregularity takes place in the camera device at the site.
Claims23
In a camera system equipped with a plurality of camera devices and a controller displaying images captured by the camera devices in real time, wherein at least one camera device comprises:
- an imaging module;
- an image compression module for compressing an image captured by the imaging module;
- a storage module for storing an image compressed by the image compression module;
- a control transmission module for sending in real time, an image stored in the storage module to the controller;
- a camera transmission module for sending an image stored in the storage module to another camera device that is at least one of the plurality of camera devices, and wherein the another camera device stores an image sent from the camera transmission module.
A camera system equipped with a plurality of camera devices wherein at least one camera device comprises:
- an imaging module;
- an image compression module for compressing an image captured by the imaging module;
- a storage module for storing an image compressed by the image compression module;
- an irregularity detection module for detecting irregularities;
- and
- a camera transmission module for sending an image stored in the storage module to another camera device that is one of the plurality of camera devices if an irregularity is detected by the irregularity detection module, and wherein the another camera device stores an image sent from the camera transmission module.
In a camera device that can be used in a camera system equipped with a plurality of camera devices, a camera device comprising:
- an imaging module;
- an image compression module for compressing an image captured by the imaging module;
- a storage module for storing an image compressed by the image compression module;
- an irregularity detection module for detecting irregularities;
- and
- a camera transmission module for sending an image stored in the storage module to another camera device that is at least one of the plurality of camera devices if the irregularity detection module detects an irregularity.
In a recording device that can be used in a camera system equipped with an internal network containing a recording device, an external network, and a controller, the internal network includes a plurality of internal camera devices, the recording device recording an image captured by the internal camera devices, and the external network includes a plurality of external camera devices and an external recording device recording an image captured by the external camera devices;
- a recording device comprising:
- a recording module recording an image captured by the internal camera device;
- a control transmission module sending an image recorded in the recording module to the controller;
- and
- an external transmission module sending an image recorded in the recording module to the external recording device.
In a recording device that can be used in a camera system equipped with an internal network containing a recording device, an external network, and a controller, the internal network including a plurality of internal camera devices and the recording device recording an image captured by the internal camera devices, and the external network including a plurality of external camera devices and an external recording device recording an image captured by the external camera devices, a recording device comprising:
- a recording module for recording an image captured by the internal camera device;
- an irregularity detection module for detecting irregularities;
- and
- a transmission module for sending to the external recording device an image recorded in the recording module if the irregularity detection module detects an irregularity.
