Apparatus and method for controlling video recording in black box for vehicle
Provided are an apparatus and a method for controlling a video recording in a black box for vehicle. The method for controlling the video recording in the black box for a vehicle according to the present invention, for example, comprises the steps of: storing a video including images of a driving vehicle; obtaining the possibility of an accident with the vehicle; and variably adjusting one or more image quality, resolution, and a frame accident possibility. The limited capacity of storage can be used by adopting the configuration. In addition, the monitoring and storage performance of the black box for a vehicle can be improved by correctly determining causes of a vehicle accident.
1. An apparatus for controlling video recording in a black box for a vehicle, the apparatus comprising:
a storage configured to store a video including images of a driving vehicle; and
a controller for configured to obtain an accident possibility for the vehicle and variably adjust at least one of a quality, a resolution and a frame per second (FPS) of the video according to the obtained accident possibility, wherein, when the accident possibility is within the predetermined range, the controller is configured to re-adjust the adjusted quality, resolution and FPS to previous values before the accident possibility exceeds the predetermined range, and records the video according to the re-adjusted quality, resolution and FPS.
2. The apparatus of claim 1 , wherein the controller is configured to obtain the accident possibility by considering at least one of a velocity and an acceleration of the vehicle.
3. The apparatus of claim 2 , wherein the controller is configured to obtain a predetermined reference value that varies according to road section in consideration of map data regarding the road section where the vehicle is currently located and obtain the accident possibility by comparing the velocity of the vehicle with the predetermined reference value.
4. The apparatus of claim 1 , wherein the controller is configured to obtain the accident possibility in consideration of the type of the road section where the vehicle is currently located.
5. The apparatus of claim 1 , wherein the controller is configured to obtain the accident possibility in consideration of whether a traffic congestion occurs on a driving route of the vehicle.
6. The apparatus of claim 5 , wherein the controller is further configured to analyze the video and determine whether the traffic congestion occurs by considering the analyzed result.
7. The apparatus of claim 6 , wherein the controller is configured to determine whether the traffic congestion occurs by considering a motion of an object included in the video into account.
8. The apparatus of claim 5 , wherein the controller is configured to determine whether the traffic congestion occurs in consideration of at least one of an acceleration pattern of the vehicle according to time and a velocity pattern of the vehicle according to time.
9. The apparatus of claim 1 , wherein the controller is configured to obtain the accident possibility in consideration of a brightness level of the video, an input audio signal level and an input audio frequency level.
10. The apparatus of claim 9 , wherein the controller is configured to obtain the accident possibility on the basis of whether a variation in the brightness level of the video meets a predetermined reference value.
11. The apparatus of claim 9 , wherein the controller is configured to obtain the accident possibility on the basis of whether the input audio frequency pattern meets a predetermined reference pattern.
12. The apparatus of claim 9 , wherein the controller is configured to obtain the accident possibility on the basis of whether the input audio signal level meets a predetermined reference level.
13. The apparatus of claim 1 , wherein, when the accident possibility exceeds a predetermined range, the controller is configured to adjust at least one of the quality, the resolution and the FPS of the video on the basis of a predetermined value and record the video according to the adjusted quality, resolution and FPS.
14. The apparatus of claim 1 , wherein the controller is configured to store obtained audio data in the storage when the accident possibility exceeds a predetermined range.
15. A method for controlling video recording in a black box for a vehicle in which the black box contains a storage device and a controller, the method comprising:
storing a video including images of a driving vehicle in the storage device; and
obtaining the accident possibility with the vehicle; and
variably adjusting at least one of a quality, a resolution and a FPS of the video according to the obtained accident possibility in the controller, wherein, when the accident possibility is within the predetermined range, the controller is configured to re-adjust the adjusted quality, resolution and FPS to previous values before the accident possibility exceeds the predetermined range, and records the video according to the re-adjusted quality, resolution and FPS.
16. The method of claim 15 , wherein the obtaining of the accident possibility comprises obtaining the accident possibility by considering at least one of a velocity and an acceleration of the vehicle.
17. The method of claim 15 , wherein the obtaining of the accident possibility comprises obtaining the accident possibility in consideration of a type of a road section where the vehicle is currently located.
18. The method of claim 15 , wherein the obtaining of the accident possibility comprises obtaining the accident possibility in consideration of a brightness level of the video, an input audio signal level and an input audio frequency level.
