Abstract

The present invention is directed to an image processing apparatus and method which is capable of safely processing and storing image data detected by a camera in a car accident. The image processing apparatus has an advantage of more safely preserving the image data, which are detected in occurrence of external impact, even when the black box device is broken due to an external impact, by promptly storing the image data in the nonvolatile and highly impact-resistant detachable memory card. In addition, the image processing apparatus of the present invention has an advantage of effectively preserving emergency-related data even with less power, by supplying power to only devices required to preserve the image data at an emergency. Furthermore, the image processing apparatus of the present invention has an advantage of preventing wasteful power consumption, by setting the apparatus to be operable corresponding to surroundings of the vehicle and extracting only image data for unusual situations.

Claims

1. An image processing apparatus comprising:

an image processing unit that processes image data detected by one or more cameras installed in a vehicle;

a sensing unit that includes one or more sensors for detecting surroundings of the vehicle;

a power source unit that receives power from the vehicle and supplies the power to other components of the vehicle;

a virtual memory unit that temporarily stores the image data;

a storing unit that stores the image data;

a detachable memory unit that backs up the image data at emergency; and

a controller that stores the image data from the image processing unit in the storing unit in stop or normal driving of the vehicle based on detection information from the sensing unit, and stores the image data of the virtual memory unit in the detachable memory unit at the emergency,

wherein the controller interrupts supply of power to various components at the emergency, except the virtual memory unit, the detachable memory unit and the controller itself, based on the detection information from the sensing unit.

2. The image processing apparatus according to claim 1, wherein the sensing unit detects collision of the vehicle with an external object, movement of the vehicle and interruption of supply of power.

3. The image processing apparatus according to claim 2, wherein the sensing unit further collects information on driving and conditions of the vehicle.

4. The image processing apparatus according to claim 3, wherein the controller stores vehicle-related information including the condition information on the vehicle in the detachable memory unit at the emergency based on the detection information from the sensing unit.

5. The image processing apparatus according to claim 1, wherein the power source unit further includes a supplementary power supply for supplying supplementary power if the power supplied from the vehicle is interrupted.

6. The image processing apparatus according to claim 1, wherein the controller maintains supply of power to the cameras, the image processing unit, the virtual memory unit, the detachable memory unit and the controller itself at the emergency based on the detection information from the sensing unit.

7. The image processing apparatus according to claim 1, wherein the storing unit comprises a hard disk or a nonvolatile memory.

8. The image processing apparatus according to claim 1, wherein the detachable memory unit comprises a detachable memory card.

9. The image processing apparatus according to claim 1, further comprising a communication unit which is connected to the controller for communication with external modules, wherein the controller outputs the detection information and the image data through the communication unit.

10. The image processing apparatus according to claim 1, further comprising an interface that is connected to the controller for receiving input from a user, wherein the controller switches between its operation conditions according to the input from the user through the interface.

11. The image processing apparatus according to claim 2, wherein the controller stores vehicle-related information including the condition information on the vehicle in the detachable memory unit at the emergency based on the detection information from the sensing unit.
