Pre-record data storage device and pre-record data storage method
View Patent ↗A pre-record data storage device includes: a first recorder; a second recorder having a capacity larger than that of the first recorder; a face comparison processor that executes a face comparison process on a person's face detected from an image obtained by photographing the person; and a recording controller. The recording controller allows the first recorder to start pre-recording of the image of the person from a face detection time when the person's face is detected, and to finish the pre-recording at a matched time when matching is confirmed as a result of the face comparison process of the face comparison processor. The recording controller stores pre-recorded data from the face detection time to the matched time in the second recorder.
1. A pre-record data storage device comprising:
a first recorder;
a second recorder having a capacity larger than a capacity of the first recorder;
a face comparison processor that executes a face comparison process to compare a person's face detected from an image obtained by photographing the person with registered face information; and
a recording controller that allows the first recorder to start recording from a face detection time when the person's face is detected until a matched time when the detected person's face matches the registered face information at the face comparison processor, to record pre-recording data, and when the detected person's face matches the registered face information at the face comparison processor, stores the pre-recording data from the face detection time to the matched time in the second recorder.
2. The pre-record data storage device according to claim 1 ,
wherein when the detected person's face does not match the registered face information at the face comparison processor, the pre-recording data is not stored in the second recorder.
3. The pre-record data storage device according to claim 1 , further comprising:
a face detecting time storage that stores the face detection time,
wherein the recording controller uses the face detection time stored in the face detection time storage as an index time of the pre-recording data when the pre-recording data is stored from the face detection time to the matched time in the second recorder.
4. A pre-record data storage method comprising:
executing a face comparison process to compare a person's face detected from an image obtained by photographing a person with registered face information; and
allowing a first recorder to start recording from a face detection time when the person's face is detected until a matched time when the detected person's face matches the registered face information, to record pre-recording data, and when the detected person's face matches the registered face information, storing the pre-recording data from the face detection time to the matched time in a second recorder having a capacity larger than a capacity of the first recorder.
5. A non-transitory computer readable storage medium storing one or more programs, the one or more programs comprising instructions, which, when executed by a pre-record data storage device, cause the device to:
execute a face comparison process to compare a person's face detected from an image obtained by photographing a person with registered face information; and
allow a first recorder to start recording from a face detection time when the person's face is detected until a matched time when the detected person's face matches the registered face information, to record pre-recording data, and when the detected person's face matches the registered face information, storing the pre-recording data from the face detection time to the matched time in a second recorder having a capacity larger than a capacity of the first recorder.
