Abstract
Description
- This application is based on and claims the benefit of priority to Korean Patent Application No. 10-2014-0044840, filed on Apr. 15, 2014 in the Korean Intellectual Property Office, the entire content of which is incorporated herein by reference.
- The present disclosure relates to an apparatus and a method for processing an image recorded in a black box for a vehicle, and more particularly, to a technology of encoding an image recorded in a black box for a vehicle with an intra mode or an inter mode according to a condition (e.g., state) of a driving road.
- Generally, a process of encoding moving pictures includes processes of image preprocessing, motion estimation and compensation, transform, quantization, variable length coding, determination of an encoding mode, a transmission rate control, and the like.
- Here, in the determination of the encoding mode, a motion is estimated in an integer pixel unit and then it is determined whether a macro block is encoded with the intra mode or with the inter mode.
- In the intra mode, the macro block is encoded by the processes of transform, quantization, and variable length coding. In this case, the motion estimation and compensation are not required.
- On the other hand, in the inter mode, the motion estimation is performed on a current block and a motion vector (MV) is obtained as a displacement from a predicted block for the current block.
- Next, after the motion is compensated from the motion vector (MV), a pixel value of the predicted block is subtracted from the current block to make a residual block and then the residual block is encoded by the same method as the intra macro block. In this case, the motion vector (MV) and texture information of the residual block are transmitted to a decoder, in which the decoder may add the quantized residual block to the predicted block by the motion vector to obtain a reconstructed image for the current block.
- However, the moving pictures having less motion have a lot of temporal correlation and therefore a residual signal of the residual block is very small in a current frame.
- Therefore, the number of bits required to encode the residual signal and the number of bits required to encode the motion vector are smaller than the number of bits required to encode the current block. In this case, the inter mode is appropriate.
- On the other hand, when region generations, which overlap or are exposed by a rapid motion or a motion of an object, and a scene change occur, it is difficult to predict the macro block.
- Therefore, since the number of bits required to encode the motion vector and the residual signal is larger than the number of bits required to encode a block of an original image, encoding the original image with the intra mode is preferable in terms of encoding efficiency and subjective image quality.
- The method for determining an encoding mode according to the related art needs to include a process of comparing energy of the predicted residual signal with energy of the original image to determine the intra mode or the inter mode and therefore it takes a long encoding time due to a complicated computing process.
- The present disclosure has been made to solve the above-mentioned problems occurring in the prior art while advantages achieved by the prior art are maintained intact.
- An aspect of the present disclosure provides an apparatus and a method for processing an image recorded in a black box for a vehicle capable of shortening a determination time of an encoding mode and effectively processing (e.g., storing) an image, by determining whether the image recorded in the black box for the vehicle is encoded with an intra mode or an inter mode according to a condition (e.g., state) of a driving road.
- The foregoing and other objects, features, aspects and advantages of the present disclosure will be understood and become more apparent from the following detailed description of the present disclosure. Also, it can be easily understood that the objects and advantages of the present disclosure can be realized by the units and combinations thereof recited in the claims.

Accordingly, those having ordinary knowledge in the related art to which the present disclosure pertains will easily embody technical ideas or spirit of the present disclosure.

Hereinafter, exemplary embodiments of the present inventive concept will be described in detail with reference to the accompanying drawings.
-
FIG. 1 is a configuration diagram of an apparatus for processing an image recorded in a black box for a vehicle according to an exemplary embodiment of the present inventive concept. - As illustrated in
FIG. 1 , the apparatus for processing an image recorded in a black box for a vehicle according to the exemplary embodiment of the present inventive concept may include aninformation collector 10, a mode determiner 20, anencoder 30, acontroller 40, and astorage 50. - Describing each component, the
information collector 10 may collect information on a road (e.g., suburban road, city road) on which a vehicle is being driven and traffic information (e.g., congestion, delay, slow moving, smoothness) on a road on which a vehicle is being driven. - The
information collector 10 may collect the road information and the traffic information through a navigation device equipped in a vehicle, but may also collect the road information and the traffic information by being linked with a portable terminal (e.g., a smart phone, and the like) which may access a web. The traffic information may also be collected from radio broadcasting, digital multimedia broadcasting (DMB), and terrestrial broadcasting. - Here, the ‘suburban road’ may collectively refer to a road located at the suburbs in the administrative district and the ‘city road’ may collectively refer to a road located within a city in the administrative district. The suburban road may have a small number of buildings located in the vicinity of a road but the city road may have a large number of buildings located in the vicinity of a road, compared to the suburban road.
- Further, in a general road, the ‘congestion’ may refer to the case in which a driving speed of a vehicle is within 10 km/h, the ‘delay’ may refer to the case in which a driving speed of a vehicle exceeds 10 km/h but is within 30 km/h, the ‘slow moving’ may refer to the case in which a driving speed of a vehicle exceeds 30 km/h but is within 50 km/h, and the ‘smoothness’ may refer to the case in which a driving speed of a vehicle exceeds 50 km/h.

- Navigation devices may provide the traffic information (e.g., congestion, delay, slow moving, smoothness) according to a kind of road and therefore the
information collector 10 may collect the information provided by the navigation device. - Consequently, the ‘congestion’, ‘delay’, ‘slow moving’, and ‘smoothness’ may have respective speed sections which may be different according to the kind of road.

mode determiner 20 may determine the encoding mode by the following two methods. - 1) In the case in which the information collected by the
information collector 10 is road information: when the road information is the suburban road, the road may be determined as a lonely road and an inter mode may be determined, and when the road information is the city road, the road may be determined as a busy road and the intra mode may be determined. - 2) In the case in which the information collected by the
information collector 10 is the traffic information: when the traffic information is smooth, traffic volume may be determined to be small and the inter mode may be determined, and when the traffic information is not smooth, a traffic volume may be determined to be heavy and the intra mode may be determined. - Next, the
encoder 30 may encode the image recorded in the black box with an encoding mode determined by themode determiner 20. - Next, the

information collector 10 may collect the information on a road on which a vehicle is being driven (201). - Next, the
mode determiner 20 may check the road information collected by the information collector 10 (202). - As a result of the checking (202), if it is determined that the road is the suburban road, the inter mode may be determined (203).
- As a result of the checking (202), if it is determined that the road is the city road, the intra mode may be determined (204).
- Next, the
encoder 30 may encode the image recorded in the black box with the encoding mode determined by the mode determiner 20 (205). - Next, the
storage 50 may store the image encoded by the encoder 30 (206). -

information collector 10 may collect the traffic information (e.g., congestion, delay, slow moving, smoothness) on the road on which the vehicle is being driven (301). - Next, the
mode determiner 20 may check whether the traffic information collected by theinformation collector 10 is smooth (302). - As a result of the checking (302), if it is determined that the traffic information is smooth, the inter mode may be determined (303).
- As a result of the checking (302), if it is determined that the traffic information is not smooth, the intra mode may be determined (304).
- Next, the
encoder 30 may encode the image recorded in the black box with the encoding mode determined by the mode determiner 20 (305). - Next, the
storage 50 may store the image encoded by the encoder 30 (306). - Meanwhile, the method according to the exemplary embodiment of the present inventive concept as described above may be prepared by a computer program. Codes and code segments configuring the computer program may be easily deduced by computer programmers in the art. In addition, the computer program may be stored in computer readable recording media (e.g., information storage media) and may be read and executed by computers, thereby implementing the methods according to the present disclosure. Further, the recording media may include any type of recording media which may be read by a computer.
- As described above, according to the exemplary embodiments of the present inventive concept, it is possible to shorten the determination time of the encoding mode and efficiently process (e.g., store) the image, by determining whether the image recorded in the black box for the vehicle is encoded with the intra mode or the inter mode according to the condition (e.g., state) of the driving road.
- The present disclosure described above may be variously substituted, altered, and modified by those skilled in the art to which the present disclosure pertains without departing from the scope and spirit of the present disclosure. Therefore, the present disclosure is not limited to the above-mentioned exemplary embodiments and the accompanying drawings.
