Apparatus and Method of Processing Video in the Video Recording System for the Vehicles

The present invention relates to an image processing apparatus and method in a vehicle image storage system, and more particularly, to an image processing apparatus in a vehicle image storage system configured to process an image signal received through a camera according to a state of a vehicle in a vehicle image storage system; It is about a method.

Recently, a vehicle image storage system for storing an accident scene of a vehicle as an image when a vehicle accident, such as a vehicle crash, a vehicle contact, a vehicle breakdown, etc. has been developed has been very useful for analyzing the cause of a vehicle accident.

In general, an image storage system for a vehicle stores an image from a camera in a memory from a predetermined time before a vehicle accident to a predetermined time after the vehicle accident occurs in a vehicle accident, and then from the memory when analyzing the cause of the vehicle accident. Read the stored image and display it on LCD, monitor, etc.

Then, as shown in FIG. 1, an image processing apparatus in a general vehicle image storage system includes a camera unit 110, a digital signal processing unit 120, a compression unit 130, and a memory unit 140.

The camera unit 110 photographs the surroundings of the vehicle and applies the photographed image signal to the digital signal processor 120.

The digital signal processing unit 120 converts the image signal applied from the camera unit 110 into image data for storing in the memory unit 140 and applies it to the compression unit 130. In this case, the digital signal processor 120 may include coordinate data applied from a gyro sensor (not shown in the drawings for convenience of description), impact level data applied from an impact sensor (not shown in the drawings for convenience of description, and a memory unit). Applied from text data (for example, image storage display text, event occurrence display text, play / pause display text, menu display text, etc.) read out from 140, a timer (not shown in the figure for convenience of explanation). The video signal applied from the camera unit 110 is synthesized together with the time data, and the like is generated as image data and applied to the compression unit 130.

The compression unit 130 compresses the image data applied from the digital signal processing unit 120 using various compression formats (for example, AVI, WIMV, ASF, MPG, MP4, etc.) to compress the compressed image data into a memory unit ( 140).

The memory unit 140 stores programs and data necessary for the control operation and operation of the vehicle image storage system. In particular, the memory unit 140 stores compressed data applied from the compression unit 130. In addition to the internal memory, the memory unit 140 may use a separate external memory card for storing compressed data applied from the compression unit 130.

The image processing apparatus of the conventional vehicle image storage system having the above-described configuration always processes the image signal applied from the camera unit 110 at a constant number of frames, a constant resolution (or number of pixels, pixels), or the like. The memory unit 140 stores the data in the memory 140.

By the way, when the vehicle is parked or stopped and there is no movement in the vehicle itself and the change of the surrounding situation is not so large, the video signal applied from the camera unit 110 is converted into a normal number of frames (for example, 15 (frame / sec)) and resolution (or the number of pixels, pixels) (e.g., 640 * 480) and the image data stored in the memory unit 140 can be analyzed later. In this case, the surrounding situation of the vehicle photographed through the camera unit 110 may be sufficiently analyzed. Nevertheless, since the image signal applied from the camera unit 110 is always processed at a constant number of frames and resolution (or number of pixels, pixels), the memory utilization of the memory unit 140 occupies a large amount of memory utilization and thus many There is a disadvantage in that the video signal of time cannot be stored continuously.

On the other hand, when the vehicle travels at a high speed or when the movement of the subject photographed by the camera unit 110 is very fast, the image signal applied from the camera unit 110 may display the frame number and the resolution (or the number of pixels, If the image data is stored in the memory unit 140 and later, when the image data stored in the memory unit 140 is reproduced and analyzed, the surrounding situation of the vehicle captured by the camera unit 110 may be sufficiently analyzed. It becomes impossible. That is, when the speed of the vehicle is fast or the movement of the subject is fast, the image stored in the memory unit 140 must be processed by processing the image signal applied from the camera unit 110 at the appropriate frame number and resolution (or the number of pixels and pixels). When the data is reproduced, the surrounding situation of the vehicle can be sufficiently expressed. Otherwise, grasping the situation of the vehicle accident can be roughly performed, but there are disadvantages that may occur when the actual accident scene of the vehicle is not secured.

The technical problem to be achieved by the present invention is to solve the problems or necessity as described above, the frame number or the resolution (or the number of pixels) according to the state of the vehicle for the image signal applied through the camera in the vehicle image storage system And an image processing apparatus and method in an image storage system for a vehicle to automatically adjust and process pixels).

In order to solve this problem, according to the present invention, in the vehicle image storage system to determine the current state of the vehicle (that is, whether the vehicle is running or not) and the frame number or resolution (or pixel number corresponding to the identified vehicle state) , To automatically process the video signal received through the camera and store it in the memory. In addition, the present invention is the image is applied through the camera is adjusted to be smaller than the frame number or resolution (or the number of pixels, pixels) set as a reference when the vehicle is parked or stopped and the movement of the subject photographed through the camera is small On the other hand, when the speed of the vehicle is fast or the movement of the subject photographed through the camera is large, the image applied through the camera is adjusted to be larger than the reference frame number or the reference resolution (or the number of pixels and pixels). Implement to process signals.

As shown in FIG. 2, an image processing apparatus in a vehicle image storage system according to an exemplary embodiment of the present invention may include a camera unit 210, a digital signal processor 220, a compressor 230, and a memory 240. The vehicle state detection unit 250 and the control unit 260 are included. The camera unit 210, the digital signal processor 220, and the compressor 230 are similar in structure to the camera unit 110, the digital signal processor 120, and the compressor 130 illustrated in FIG. 1. The description is omitted.

The memory unit 240 may have a preset number of frames (for example, 30 (frame / sec), 15 (frame / sec), 7.5 (frame / sec), etc.) or a resolution (for example, depending on the state of the vehicle). 1280 * 960, 640 * 480, 320 * 240, etc.) (or the number of pixels, pixels) are stored in a database.

As a first example, the memory unit 240 presets the number of frames or the resolution (or the number of pixels, the pixels) corresponding to the shooting mode (that is, whether the vehicle is driving) in the vehicle image storage system according to an embodiment of the present invention. For example, in non-driving shooting mode, set the frame number to '7.5 (frame / sec)' or set the resolution to '320 * 240' and save it. Set to '30 (frame / sec) 'or set the resolution to' 1280 * 960 'and save it. Here, the non-driving photographing mode is a mode in which the subject is photographed through the camera unit 210 in a parked or stopped state (that is, a non-driving state) in which the vehicle is not driving, and the driving photographing mode is a vehicle in which the vehicle is currently driving. In this state (that is, the driving state) is a mode for photographing the subject through the camera unit 210.

As a second example, the memory unit 240 presets and stores the frame number or resolution (or the number of pixels and pixels) corresponding to the degree of change in the movement of the subject photographed by the camera unit 210. If the movement of the camera is small, set the frame number to '7.5 (frame / sec)' or set the resolution to '320 * 240' and save it. sec) 'or the resolution is set to' 1280 * 960 'and saved. Here, the degree of change in the movement of the subject may be achieved by checking how many times the automatic adjustment of sensitivity, illuminance, focus, etc. performed by the camera unit 210 is performed according to the movement of the subject photographed through the camera unit 210. have. For example, the number of frames or the resolution (or the number of pixels, the pixels) may be preset and stored according to the number of automatic adjustments performed by the camera unit 210 for a predetermined time.

As a third example, the memory unit 240 presets and stores the frame number or resolution (or the number of pixels and pixels) corresponding to the driving speed of the vehicle. For example, the driving speed of the vehicle is low (ie, 40 ( less than km), and set the number of frames to '7.5 (frame / sec)' or set the resolution to '320 * 240' and save the vehicle's driving speed at medium speed (ie 40 to 80 (km)). If the frame rate is set to '15 (frame / sec) 'or the resolution is set to' 640 * 480 'and stored, and the frame rate is high when the vehicle's driving speed is higher than 80 (km) Set to '30 (frame / sec) 'or set the resolution to' 1280 * 960 'and save it.

The vehicle state detector 250 checks the current state of the vehicle and applies a notification signal corresponding to the identified vehicle state to the controller 260.

In the first example, the vehicle state detection unit 250 checks whether the vehicle is currently in a non-driving state or a driving state by using a GPS, a gyro sensor, an impact sensor, a speed sensor, and whether the vehicle is checked. The controller 260 is notified.

As a second example, the vehicle state detecting unit 250 checks the degree of change in movement of the subject photographed through the camera unit 210 and notifies the control unit 260 of the degree of change in movement of the identified subject. Here, the degree of change in the movement of the subject may be confirmed using a speed sensor that detects the speed of the moving subject within the reference focal length of the lens sensor of the camera unit 210.

As a third example, the vehicle state detecting unit 250 checks the current driving speed of the vehicle through a GPS, a speed sensor, a speedometer of the vehicle, and notifies the controller 260 of the confirmed driving speed of the vehicle.

The control unit 260 receives the notification signal from the vehicle state detecting unit 250 to check the current vehicle state, and stores the frame number or resolution (or the number of pixels and pixels) corresponding to the identified vehicle state in the memory unit ( Read from the 240, and controls the operation of the digital signal processing unit 220 to process the image signal received through the camera unit 210 to the number of frames or the resolution of the read through the compression unit 230 through the memory unit 240 Save it to

As a first example, the controller 260 is notified of whether the vehicle is in a non-driving state or a driving state from the vehicle state detecting unit 250, and the number of frames registered in the memory unit 240 according to whether the vehicle is notified of the driving or the like. The resolution (or the number of pixels and pixels) is read, and the image signal applied through the camera unit 210 is processed at the read frame number or the resolution (or the number of pixels and pixels). For example, when the vehicle is in a non-driving state, '7.5 (frame / sec)', which is the number of frames corresponding to the non-driving shooting mode, or '320 * 240', which is a resolution, is read from the memory unit 240, and the camera unit is read. The digital signal processor 220 controls the operation of the digital signal processor 220 to adjust the number of frames to '7.5 (frame / sec)' or to adjust the resolution to '320 * 240' for the image signal received through 210. In addition, when the vehicle is in a driving state, '30 (frame / sec) 'or' 1280 * 960 ', which is the number of frames corresponding to the driving shooting mode, is read from the memory unit 240, and the camera unit 210 is read. The digital signal processor 220 controls the operation of the digital signal processor 220 to adjust the number of frames to '30 (frame / sec) 'or to adjust the resolution to' 1280 * 960 '.

As a second example, the control unit 260 is notified of the change in the movement of the subject from the vehicle state detection unit 250, and the number or resolution of the frame registered in the memory unit 240 (or The number of pixels, pixels) is read, and the image signal applied through the camera unit 210 is processed at the read frame number or resolution (or number of pixels, pixels). For example, when the degree of change in the movement of the subject is small, the frame number is adjusted to '7.5 (frame / sec)' for the image signal applied through the camera unit 210 or the resolution is set to '320 * 240'. The operation of the digital signal processor 220 is controlled to be adjusted. In addition, when the degree of change in the movement of the subject is large, adjust the number of frames to '30 (frame / sec) 'or the resolution to' 1280 * 960 'for the image signal applied through the camera unit 210. To control the operation of the digital signal processor 220.

As a third example, the control unit 260 is notified of the driving speed of the vehicle from the vehicle state detecting unit 250, and the number of frames or resolution (or number of pixels registered in the memory unit 240) according to the received driving speed of the vehicle. , Pixels), and process the image signal applied through the camera unit 210 at the read frame number or resolution (or pixel number, pixels). For example, when the driving speed of the vehicle is a low speed (ie, less than 40 km), the number of frames is adjusted to '7.5 (frame / sec)' for the video signal received through the camera unit 210. Controls the operation of the digital signal processor 220 to adjust the resolution to '320 * 240'. In addition, when the driving speed of the vehicle is a medium speed (ie, 40 to 80 (km)), the number of frames is adjusted to '15 (frame / sec) 'or the resolution of the video signal received through the camera unit 210. Controlling the operation of the digital signal processor 220 to adjust the '640 * 480'. In addition, when the driving speed of the vehicle is a high speed (ie, greater than 80 km), the number of frames is adjusted to '30 (frame / sec) 'or the resolution of the video signal received through the camera unit 210. Control the operation of the digital signal processor 220 to adjust to '1280 * 960'.

The controller 260 may use the first, second, and third examples described above in combination of two or more. For example, the controller 260 may combine the first and second examples described above, The first and third examples may be combined, the second and third examples described above may be combined, or the first, second and third examples described above may be operated in combination.

In the case of combining the first and second examples described above, when the vehicle is in a non-driving state and the movement of the subject is small, the number of frames is set to '7.5 (frame / sec) for the image signal applied through the camera unit 210. Adjust the resolution to '320 * 240' or adjust the resolution to '320 * 240'. When the vehicle is not driving and there is a lot of change in the movement of the subject, the number of frames for the image signal received through the camera unit 210 is set to '15 (frame). / sec) 'or the resolution is adjusted to' 640 * 480 ', and the number of frames is set to '30 for the image signal received through the camera unit 210 when the vehicle is in a driving state and the movement of the subject is large. (frame / sec) 'or adjust the resolution to' 1280 * 960 '.

In the case of combining the second and third examples described above, the image signal applied through the camera unit 210 when the movement of the subject is small and the vehicle traveling speed is low (that is, less than 40 km) is applied. Adjust the number of frames to '7.5 (frame / sec)' or adjust the resolution to '320 * 240', change the movement of the subject a lot, and drive the vehicle at medium speed (ie 40 ~ 80 (km)). In this case, the number of frames is adjusted to '15 (frame / sec) 'or the resolution is' 640 * 480' for the video signal applied through the camera unit 210. When the speed is high (ie, over 80 km), adjust the number of frames to '30 (frame / sec) 'for the video signal received through the camera unit 210, or change the resolution to' 1280 * 960 '. Adjust it.

Alternatively, the controller 260 may preset a reference frame with respect to an image signal applied through the camera when the vehicle is in a non-driving state, a movement change of a subject photographed through the camera is small, or the driving speed of the vehicle is low. It controls the operation of the digital signal processor 220 to be smaller than the number or the reference resolution (or the number of pixels, pixels), while the camera is operated when the speed of the vehicle is fast or the movement of a subject photographed through the camera is large. The digital signal processor 220 controls the operation of the digital signal processor 220 to be larger than the preset reference frame number or reference resolution (or the number of pixels and pixels) with respect to the image signal applied through the digital signal.

Hereinafter, an image processing method in a vehicle image storage system according to an exemplary embodiment of the present invention will be described in detail with reference to the flowchart of FIG. 3.

First, the number of frames (eg, 30 (frame / sec), 15 (frame / sec), 7.5 (depending on the state of the vehicle (ie, whether the vehicle is traveling, the degree of movement of the subject, the traveling speed of the vehicle, etc.)) frame / sec), or a database in which information about a resolution (for example, 1280 * 960, 640 * 480, 320 * 240, etc.) (or the number of pixels and pixels) is set in advance according to an embodiment of the present invention. It is stored in the memory unit 240 provided in the vehicle image storage system.

Alternatively, a user or an operator may directly perform an initial setting operation through an input unit (not shown in the drawings for convenience of description) provided in the vehicle image storage system according to an exemplary embodiment of the present invention. For example, information about the number of frames or the resolution (or the number of pixels and pixels) may be preset and registered in the database of the memory unit 240.

In the first example, the driving mode is classified into non-driving shooting mode and driving shooting mode according to whether the vehicle is not driven or is parked or stopped or whether the vehicle is currently driving.

As a second example, the degree of change in movement of a subject photographed through the camera unit 210 included in the vehicle image storage system according to an embodiment of the present invention is divided into small, medium, and 'Small' sets the number of frames to '7.5 (frame / sec)' or sets the resolution to '320 * 240' and stores them in the memory unit 240. Is set to '15 (frame / sec) 'or the resolution is set to' 640 * 480 'and stored in the memory unit 240. The number of frames for which the movement of the subject is large is '30 (frame / sec)' ) 'Or the resolution is set to' 1280 * 960 'and stored in the memory unit 240.

In this case, the frame number or the resolution (or the number of pixels and the pixels) may be stored in advance in response to the number of automatic adjustments such as sensitivity, illuminance, and focus performed by the camera unit 210 according to a change in the movement of the subject for a predetermined time. Can be. Alternatively, when using a speed sensor that detects the speed of the moving subject within the reference focal length of the lens sensor of the camera unit 210, it corresponds to the speed of the moving subject (eg, divided into low speed, medium speed, and high speed). The number of frames or resolution (or number of pixels, pixels) can be set and stored in advance.

Third example, low speed (eg less than 40 (km)), medium speed (eg, 40 to 80 (km)), high speed (eg, more than 80 (km)) for each vehicle's driving speed When the driving speed of the vehicle is low, the frame number is set to '7.5 (frame / sec)' or the resolution is set to '320 * 240' and stored in the memory unit 240. Medium speed sets the number of frames to '15 (frame / sec) 'or sets the resolution to' 640 * 480 'and stores them in the memory unit 240. / sec) 'or the resolution is set to' 1280 * 960 'and stored in the memory unit 240.
