For example, if it is determined that the environment around the vehicle is not significantly changing because the driver is looking ahead or the vehicle is moving fast, the video may be shortened by rapidly adjusting the speed of the time-lapse video.

In addition, when the driver is not looking ahead and the speed of the vehicle is slow, it is determined that the driver is interested in the environment around the vehicle and the time-lapse video speed is adjusted slowly so that the surrounding environment can be recorded in detail. See FIG. 1 for a more detailed description.

The image acquisition unit 10 may include a SVM (SURROUND VIEW MONITOR) device that is installed outside the vehicle and acquires an image around the vehicle. The image acquisition unit 10 may be configured to be installed apart from the time-lapse image generating device by being connected to the time-lapse image generating device by wire or wirelessly. In this case, it is configured to communicate with the time-lapse video generating device through a communication module such as a wired cable or Bluetooth, WiFi, or infrared communication.

The image processing unit 11 may generate a video based on the image obtained from the image acquisition unit 10. Moving pictures can be processed by changing the shooting speed (frames per second). For example, if the number of frames per second is processed to have an average value (eg, 30 FPS), a general video can be created, and if the number of frames per second is processed to have a value smaller than the average value (eg, less than 30 FPS), that is, time-lapse or time-lapse shooting Then, you can create a time-lapse video.

In addition, the image processing unit 11 may increase the time-lapse video speed by reducing the time-lapse shooting speed even in time-lapse photography or time-lapse photography. Increasing the time-lapse image speed may be understood as increasing the speed at which the time-lapse photographed image is reproduced. Also, the image processing unit 11 may decrease the time-lapse image speed by increasing the time-lapse photographing speed. Reducing the time-lapse video speed may be understood as slowing down the speed at which the time-lapse photographed video is reproduced.

According to the embodiment, when the image processing unit 11 processes an image at a first speed in generating a time-lapse video, the image processing unit 11 converts the image to a second speed slower than the first speed in order to increase the time-lapse video speed. images can be processed.

For reference, time-lapse photography or time-lapse photography is a technique in which the capture cycle of frames is lower than that of consecutive frames, and the time-lapse or time-lapse images can be expressed as fast motion even when reproduced at normal speed. For example, if the process of blooming flowers is filmed and played back at normal speed, the process of blooming and changing cannot be discerned at a glance. It is easily recognizable because it is expressed as

It can receive map information transmitted from the server of .

In addition, the communication unit 30 may be connected to other devices to transmit and receive multimedia data. Specifically, the communication unit 30 may be connected to a mobile terminal located near the vehicle or a server located in a remote location, and transmit multimedia data from the mobile terminal or server. For example, the communication unit 30 may be connected to a user's smart phone and receive multimedia stored in the smart phone.

The navigation 40 may store map information including information such as the number of lanes, curvature, and state of lanes. Also, POI information based on map data may be stored. The region of interest may be stored as a region of interest to the driver, and may include major facilities, stations, airports, terminals, hotels, famous tourist attractions, and the like.

The map stored in the navigation 40 may include a precision map including detailed information such as a lane marking state of the driving lane R. In addition, the navigation 40 may receive GPS information by including a location measuring unit. The position measurement unit may be included in the navigation 40 and provided integrally with the navigation 40 or may be provided separately from the navigation 40 .

The position measurement unit measures the current position of the vehicle. The location measurement unit may be implemented as a Global Positioning System (GPS) module. The GPS module calculates the current location of the vehicle using signals transmitted from three or more GPS satellites. The GPS module calculates the distance between the satellite and the GPS module using a time difference between a time when a signal is transmitted from a satellite and a time when a signal is received by the GPS module. The GPS module calculates the current location of the vehicle using the calculated distance between the satellite and the GPS module and location information of the satellite included in the transmitted signal. At this time, the GPS module calculates the current location of the vehicle using triangulation.

The controller 70 may control the overall operation of the time-lapse image generating device. The controller 70 includes application specific integrated circuits (ASICs), digital signal processors (DSPs), programmable logic devices (PLDs), field programmable gate arrays (FPGAs), central processing units (CPUs), microcontrollers, and microprocessors. (microprocessors) may include at least one or more.

The control unit 70 may acquire an image from the image acquisition unit 10 for a time set by the user from when the destination is set until arriving at the destination, and cause the image processing unit 11 to generate a video.

According to an embodiment, the control unit 70, when it is determined that the vehicle is traveling at a predetermined speed or more, even if the driver's gaze is not looking forward, takes a time-lapse video but reduces the time-lapse shooting speed to capture the time-lapse video. speed can be increased. Here, the video speed may mean a playback speed.

In order to increase the speed of the time-lapse photographed image, the interval of frames per second may be adjusted to be long. An increase in the interval of frames per second means that the number of frames captured per second decreases (reduction in shooting speed), and the FPS can be adjusted to have a small value.

For example, if it was filming at a first speed for time-lapse filming, and the control unit 70 determines that the vehicle is traveling at a predetermined speed or more, the image processing unit ( 11) can be controlled.

In addition to the above-described embodiment, the control unit 70 determines that the vehicle is driving on a highway or passing through a toll gate, or determines that the current location of the vehicle is not located in the region of interest, the second speed that is slower than the above-described first speed You can control to shoot with . In this way, the control unit 70 controls the second speed slower than the first speed to take the time-lapse, and determines that there is no significant change in an environment where there is no area of interest and only roads are repeated, such as on a highway. This is to shorten the video by making the video play quickly.

According to another embodiment, the control unit 70, when it is determined that the driver's gaze is looking forward and the current vehicle is located in the region of interest, takes time-lapse, but increases the time-lapse shooting speed to speed the time-lapse captured image. can be reduced. To this end, it is possible to photograph by adjusting the interval of frames per second to be short. Shortening the interval of frames per second means that the number of frames captured per second increases (shooting speed increases), and the FPS can be adjusted to have a high value.

For example, when shooting was performed at a first speed for time-lapse photography, and the controller 70 determines that the driver's gaze is looking forward and the current vehicle is located in the region of interest, a third speed faster than the first speed It is possible to control the image processing unit 11 to take a time-lapse video.

In addition to the above-described embodiment, the control unit 70 determines that the driver is looking at the side of the vehicle instead of the front of the vehicle, or the vehicle speed is less than the predetermined speed, so that the controller 70 shoots at a third speed faster than the first speed. You can control it. In this way, the control unit 70 adjusts the third speed faster than the first speed to take time-lapse photography, so that the surrounding scenery of the region of interest is recorded in detail.

2 is a flowchart illustrating a method for generating a time-lapse image using a vehicle camera of the present invention.

First, an image around the vehicle may be obtained, and a time-lapse image may be generated by processing the image at a first speed using the obtained image around the vehicle. In addition, the speed of the vehicle, the location of the vehicle, and the direction of the driver's gaze can be detected.

It is determined whether the driver is looking ahead (S100). S100 may determine the direction of the driver's gaze based on the information obtained from the image acquisition unit 10 . When the driver is looking in the side direction of the vehicle, it may be determined that the driver is not looking ahead.

In S100, if the driver is not looking ahead (NO), it may be determined whether the speed of the vehicle is equal to or greater than a predetermined speed (S110). In S110, according to the embodiment, it may be determined whether the speed of the vehicle is 90 km or more.

If it is determined in S110 that the speed of the vehicle is less than the predetermined speed (N0), it may be determined whether the current vehicle is located in the region of interest (S120). Here, the region of interest may include major facilities, stations, airports, terminals, hotels, famous tourist spots, and the like.

In S120, if the current vehicle is not located in the region of interest (N0), the video speed of the time-lapse is increased (S130). In the S130, time-lapse shooting is performed, but the time-lapse shooting speed is reduced so that the speed of the time-lapse captured video is increased. Here, the speed of the time-lapse photographed image may mean the speed at which the time-lapse photographed image is reproduced.

In the S130, time-lapse recording can be performed by adjusting the interval of frames per second to be long. Adjusting the interval of frames per second to be long means that the number of frames captured per second is reduced (reducing the shooting speed), and the FPS can be adjusted to have a small value.

For example, if recording was performed at a first speed for time-lapse photography, in S130, time-lapse photography may be performed at a second speed slower than the first speed.

S130 may be performed to shorten the video so that the time-lapse video is quickly reproduced by determining that there is no significant change in the surrounding environment and driving environment of the vehicle.

In the S130, since the driver may not keep an eye on the front, it is possible to notify through a warning that the driver may be careless while driving.

If it is determined in S120 that the current vehicle is located in the region of interest (YES), the speed of the time-lapse video is reduced (S140). S140 takes time-lapse, but increases the time-lapse shooting speed so that the speed of the time-lapse captured video is reduced. Here, the speed of the time-lapse photographed image may mean the speed at which the time-lapse photographed image is reproduced.

The S140 can take a time-lapse shot by adjusting the interval of frames per second to be short. Adjusting the interval of frames per second to be short means that the number of frames captured per second increases (shooting speed increases), and the FPS can be adjusted to have a high value.

For example, if shooting was performed at a first speed for time-lapse photography, in S150, time-lapse photography may be performed at a third speed faster than the first speed.

S140 may be performed to record the surrounding environment of the vehicle in detail when it is determined that the surrounding environment and the driving environment of the vehicle are regions of interest.

Returning to S110, if it is determined in S110 that the speed of the vehicle is equal to or greater than the predetermined speed (YES), the time-lapse video speed is increased (S130). In the S130, time-lapse shooting is performed, but the time-lapse shooting speed is decreased so that the speed of the time-lapse captured video is increased. Here, the speed of the time-lapse photographed image may mean the speed at which the time-lapse photographed image is reproduced.

Returning to S100, if it is determined in S100 that the driver is looking ahead (YES), it may be determined whether the current vehicle is located in the region of interest (S120). Here, the region of interest may include major facilities, stations, airports, terminals, hotels, famous tourist spots, and the like.

In S120, if the current vehicle is not located in the region of interest (N0), the video speed of the time-lapse is increased (S130). If it is determined in S120 that the current vehicle is located in the region of interest (YES), the speed of the time-lapse video is reduced (S140).
