Hereinafter, a navigation device as a video control device of the present invention in the first embodiment will be described with reference to FIG. FIG. 1 is a block diagram showing one embodiment of a navigation device as a video control device of the present invention.

  The navigation device 1 of the present embodiment is mounted on a vehicle. As shown in FIG. 1, the navigation device 1 can reproduce a traveling image captured by the camera 11 recorded in the memory unit 12 in addition to the route guidance.

  The navigation apparatus 1 includes a camera 11, a memory unit 12, a GPS receiving unit 13, an operation unit 14, a display unit 15, a touch panel 16 as a contact sensor, a sound output unit 17, a control unit 18 (reception unit). Part).

  The camera 11 is mounted on a vehicle and captures an image of the front or the rear of the vehicle. In the present embodiment, a description will be given below assuming that the camera 11 captures an image of the front of the vehicle. The memory unit 12 stores a running image captured by the camera 11 and the like. The memory unit 12 is composed of a non-volatile memory such as a hard disk or an SD card, for example, and is read and written under the control of a control unit 18 described later.

  The GPS receiving unit 13 receives radio waves oscillated from a plurality of GPS (Global Positioning System) satellites as is known, obtains current position information, and outputs the current position information to the control unit 18. In the present embodiment, an example is shown in which the GPS receiving unit 13 is provided integrally with the navigation device 1. However, the GPS receiving unit 13 may be configured as a separate body and may be detachable from the navigation device 1. .

  The operation unit 14 includes an input unit such as a button and a voice input unit such as a microphone. The operation unit 14 performs various input operations of the navigation device 1 and outputs an operation signal indicating the input operation to the control unit 18.

  The display unit 15 includes a liquid crystal display, a driver circuit for controlling the liquid crystal display, and the like. The touch panel 16 is arranged on the display screen of the display unit 15, detects a contact of a human finger, a touch pen, or the like, and outputs a detection signal to the control unit 18.

  The audio output unit 17 includes a speaker, an amplifier for driving the speaker, and the like, and outputs audio under the control of the control unit 18.

  The control unit 18 includes a CPU (Central Processing Unit) having a memory such as a RAM (Random Access Memory) and a ROM (Read Only Memory), and controls the entire navigation device 1. The RAM is a data erasable / rewritable memory, and is a memory for temporarily storing data generated during processing by the CPU. The ROM is a memory from which data cannot be erased or rewritten, and stores a processing program executed by the CPU.

  The CPU of the control unit 18 (hereinafter simply referred to as the control unit 18) controls a display unit 15 and an audio output unit 17 to be described later to guide a route to a destination according to a program written in the ROM. In addition to the processing, a drive record process for controlling the camera 11 and the memory unit 12 to record a running image captured by the camera 11 in the memory unit 12 and a reproduction for displaying the running image recorded in the memory unit 12 on the display unit 15 Execute the process.

  Next, the features of the traveling video captured by the camera 11 that captures the front of the vehicle will be described with reference to FIG. FIG. 2 is a running image taken by the camera 11 shown in FIG. 1 when the vehicle is moving forward, FIG. 2 (A) is an image at time t, and FIG. 2 (B) is a running image at time t + Δt. It is.

As shown in FIG. 1, a running image obtained by photographing the front of the vehicle includes a white line 2 of a running path on which the vehicle runs and a stationary object such as a signboard or a building as a background 3. In such running image, a plurality of lines parallel to each other as a plurality of white lines 2, meet at the vanishing point P _1, it disappears. When playing or fast-forward the running image, since the vehicle and the background 3 approaches, the background 3, radially around the vanishing point P _1, moves away from the vanishing point P _1. In contrast, when rewinding the traveling image, since the vehicle and the background 3 leaves, the background 3, radially around the vanishing point P _1, moves toward the vanishing point P _1.

The present embodiment focuses on this, and the control unit 18 determines the reference point P ₂ on the touch panel 16 (hereinafter simply referred to as “on the display unit 15”) provided on the display unit 15 based on the vanishing point P _1. the determined, according to a user operation based on the reference point P _2, and controls the traveling image to be displayed on the display unit 15. More specifically, the control unit 18, FIG. 3 (A), the radially around the reference point P _2, the reference point P ₂ the user's finger 6 swipe or flick is thereby operated in a direction away from ( when accepting an operation) away from the reference point, and fast-forward running video, as shown in FIG. 3 (B), radially around the reference point P _2, the user in a direction approaching the reference point P ₂ fingers 6 When an operation of swiping or flicking (operation of approaching the reference point) is received, the running image is rewound.

The “swipe” is an operation of sliding a finger in a predetermined direction while touching the screen. The “flick” is an operation of moving a finger so as to lightly swipe the screen in a predetermined direction. The finger 6 in FIG. 3 is not displayed on the display unit 15 but represents an actual finger of the user touching the display unit 15. The arrows in FIG. 3 are not displayed on the display unit 15, but represent the trajectory on the display unit 15 when the user flicks or swipes. The same applies to FIGS. 5, 6 and 8 described later. Circles represent the reference point P ₂ also, although not displayed on the display unit 15 in the present embodiment, it may be displayed.

The detailed operation of the navigation device 1 described in the above outline will be described with reference to FIG. The control unit 18 performs a reproduction process when the mode is switched to the reproduction mode of the traveling image captured by the camera 11 according to the operation of the operation unit 14 or the touch panel 16, for example. In the reproduction process, the control unit 18 first performs setting of the reference point P ₂ on the touch panel 16 (step S1).

The setting of the reference point P _2, the reference point P ₂ previously stored in the memory unit 12, it is conceivable to set from the memory unit 12. The vanishing point P ₁ can be obtained in advance from such attachment position of the camera 11. For example, when fitted with the optical axis of the camera 11 so as to be horizontal to the traveling direction of the vehicle, the display screen center or near the center of the display unit 15 a vanishing point P ₁ of the running video. For this reason, the reference point P ₂ is determined in advance at the center or near the center of the display unit 15 and stored in the memory unit 12. In this way, it is possible to determine the vanishing point P ₁ or vanishing point P ₁ the reference point in the vicinity of P _2. Further, by analyzing the driving image captured by the camera 11, which is recorded in the memory unit 12 obtains the vanishing point P _1, may be determined a reference point P ₂ to the vanishing point P ₁ or vanishing point P ₁ near obtained .

  Next, when the control unit 18 receives a reproduction operation such as a reproduction button provided on the operation unit 14 or an operation of a reproduction button displayed on the touch panel 16 (Y in step S2), the control unit 18 captures an image using the camera 11, and The running video stored in the section 12 is reproduced (step S3). When the control unit 18 receives a pause operation such as a pause button provided on the operation unit 14 or an operation of a pause button displayed on the touch panel 16 (Y in step S4), the traveling being reproduced is performed. The video is paused (step S5).

Control unit 18 accepts the swipe or flick operation away from the reference point P ₂ on the display section 15 (Y in step S6), and fast forward traveling image being reproduced (step S7). The control unit 18 accepts the swipe or flick operation approaches the reference point P ₂ on the display section 15 (Y in step S8), and rewind the traveling image being reproduced (step S9).

Running images, background 3 flows radially around a vanishing point P _1. If the running image photographed in front of the vehicle as in the first embodiment, the background 3 during reproduction or fast-forward flows in a direction away from the vanishing point P _1. On the other hand, the background 3 during rewinding flows toward the vanishing point P _1. Therefore, when receiving the operation away from the reference point P ₂ which is determined based on the vanishing point P ₁ as described above, if the fast-forward, receives an instruction to approach the reference point P _2, by the rewinding In addition, the fast forward operation and the rewind operation of the traveling image can be performed intuitively when reproducing the traveling image.

(Second embodiment)
In the first embodiment described above, fast forward when receiving a swipe or flick operation away from the reference point P _2, had been rewound when accepting a swipe or flick operation approaches the reference point P _2, to It is not limited. Travel video obtained by photographing the front of the vehicle, the background 3 during reproduction or fast-forward flow in a direction away from the vanishing point P _1, the background 3 during rewind flows toward the vanishing point P _1, a first embodiment As described above, this is based on the assumption that the vehicle is moving forward. If the vehicle is back, reversed, background 3 during reproduction or fast-forward flow in the direction toward the vanishing point P _1, the background 3 during rewind flows away to the vanishing point P _1.

For this reason, if the finger 6 is swiped or flicked along the direction in which the background 3 flows during the reproduction of the traveling image in front of the vehicle when the vehicle is backing, fast forward and rewind are reversed. That is, the running image when the vehicle is back for background 3 flows toward the vanishing point P _1, the user swipes or flicks the finger 6 in a direction approaching the reference point P ₂ trying fast forward, It will rewind. Conversely, when the direction away from the reference point P ₂ in an attempt to rewind swiping a finger 6, becomes fast forward.

In the second embodiment, the control unit 18, as shown in FIG. 3 (A), if the direction away from the reference point P ₂ is accepted only operation to swipe or flick the fingers 6, the fast forward driving image performed, as shown in FIG. 5, in a direction away from the reference point P ₂ after operation for swiping the finger 6, operation for swiping the finger 6 in a circular motion continues (hereinafter, be referred to as "additional steps" If you accept the above, rewind. Further, as shown in FIG. 3 (B), if the direction approaching the reference point P ₂ is accepted only operation to swipe or flick the finger 6 performs unwinding of the running video, as shown in FIG. 6, the reference If after the operation for swiping the finger 6 in the direction approaching the point P _2, receives an instruction to swipe a finger in a circular motion continues, performs the fast forward driving image. The direction in which the circle is drawn may be clockwise, as shown in FIGS. 5A and 6A, or counterclockwise, as shown in FIGS. 5B and 6B.

  The detailed operation of the navigation device 1 described in the above outline will be described with reference to FIG. In the figure, steps that perform the same operations as in the flowchart shown in FIG. 1 already described in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted. The control unit 18 performs a reproduction process when the mode is switched to the reproduction mode of the traveling image captured by the camera 11 according to the operation of the operation unit 14 or the touch panel 16, for example. Steps S <b> 1 to S <b> 5 are the same as in the first embodiment, and thus description thereof will be omitted.

Control unit 18 receives only the operation to swipe or flick in a direction away from the reference point P ₂ on the display unit 15, if no additional operations (Y at step S10), and fast forward traveling video being played (Step S11). Control unit 18, after swiping toward the reference point P ₂ on the display unit 15, even when receiving additional operations continued (Y in step S12), and fast forward traveling video being played ( Step S11).

In contrast, the control unit 18 receives only the operation to swipe or flick in the direction toward the reference point P ₂ on the display unit 15, if no additional operations (Y at step S13), and is being reproduced The running image is rewound (step S14). The control unit 18, after swiping away from the reference point P ₂ on the display unit 15, when receiving additional operations continued (Y in step S15), and rewind the running video being played (Step S14).

  According to the above-described second embodiment, when the additional operation is performed, the feed and the return can be switched. Thus, for example, if an additional operation is performed when the traveling image when the vehicle is backing is displayed, even if the traveling image is when the vehicle is backing, the fast forward operation of the image is intuitively performed. Alternatively, a return operation can be performed.

(Third embodiment)
In the first embodiment described above, the control unit 18 accepts an operation to swipe or flick the user's finger 6 toward the direction or the reference point P ₂ away from the reference point P _2, have been fast-forward or rewind However, it is not limited to this. In the third embodiment, the control unit 18, as shown in FIG. 5, to swipe a finger 6 in a circular motion to continue after the finger 6 is swipe in a direction away from the reference point P ₂ on the display unit 15 If an operation (additional operation) is received, fast forward. Further, when receiving an operation for swiping the finger 6 in a circular motion followed After swiping the finger 6 in a direction approaching the reference point P ₂ on the display unit 15 as shown in FIG. 6, to rewind.

That is, in the third embodiment, only in the direction toward the direction or the reference point P ₂ away from the reference point P ₂ on the display unit 15 as in the first embodiment is finger swipe 6, fast forward or rewind Fast forward or rewind is performed only when an operation of swiping the finger 6 so as to draw a circle is subsequently received. That is, the fast-forward and rewind control of the traveling image is determined by the additional operation. For this reason, even if the user swipes or flicks on the display unit 15 by mistake, fast forward and rewind are not performed, so that erroneous operation can be prevented.

  In the second and third embodiments, the finger 6 is swiped so as to draw a circle as an additional operation performed after the swipe. However, the present invention is not limited to this. The additional operation may be any operation that can be distinguished from a swipe, and may be, for example, a double tap.

(Fourth embodiment)
In the first to third embodiments, when the swipe or flick operation away from approaching the reference point P ₂ or reference point P _2, then reproduction operation or fast forward or rewind to the other operations, such as the pause operation is performed Was continued, but it is not limited to this. In the fourth embodiment, when the reference point approaches the P ₂ or swipe or flick operation away from the reference point P _2, by performing only forward or rewind a predetermined control time, after the control time rewind or fast-forward The processing may be ended, and playback may be started from the end point, or paused at the end point.

At this time, it is also possible to change the control time according to the length from the start point of the swipe or flick operation away from the reference point P ₂ approaching or reference point P ₂ to the end point. That is, control may be performed such that the control time is increased and the rewind or fast-forward time is increased as the length from the start point to the end point of the swipe or flick operation is increased.

  According to the above-described fourth embodiment, it is possible to intuitively control the rewind or fast-forward time.

(Fifth embodiment)
In the fifth embodiment, the case where the finger 6 at the end of the swipe away approaching or from the reference point P ₂ to the reference point P ₂ receives an instruction to stop, exit fast forward or rewind, pause a running video You may make it. That is, while the swipe operation is being performed, the control unit 18 performs fast forward or rewind, and stops the finger 6 at the end point of the swipe operation. Pause. If the finger 6 is immediately released without stopping the finger 6 at the end point of the swipe operation, the fast-forward or rewind of the traveling image is continued.

(Sixth embodiment)
In recent years, as the camera 11, a wide-angle camera capable of, for example, 360 ° photographing has been distributed. Therefore, as shown in FIG. 8 (A), when receiving a swipe operation of crossing over the reference point P _2, as shown in FIG. 8 (B), it may be changed viewpoint. For example, when the viewpoint is moved to the right, the background 3 such as a building moves to the left. Therefore, when receiving a swipe operation of crossing over the reference point P _2, and displays the running video moving the viewpoint swipe the direction opposite to the direction. Thus, the background 3 moves in the same direction as the swipe direction, and an intuitive viewpoint changing operation can be performed.

In the first to sixth embodiments described above, but I want to perform fast forward or rewind and accepting an operation closer to or away from the reference point P ₂ from the reference point P _2, not limited to this. For example, it may be returned frame advance or frame when receiving an operation approaching away from the reference point P ₂ or the reference point P ₂ is paused.

Further, in the first to sixth embodiments described above, the camera 11 is installed toward the front of the vehicle and reproduces a video image of the front of the vehicle. However, the present invention is not limited to this. The camera 11 may be installed facing the rear of the vehicle to reproduce a running image of the rear of the vehicle. Image obtained by photographing the vehicle rear, in contrast to the images taken in front of the vehicle flows in the direction the background during playback or fast forward is closer to the vanishing point P _1. Further, the background during rewinding flows away to the vanishing point P _1. Therefore, when reproducing an image obtained by photographing the vehicle rear, reception in contrast to the first embodiment, when receiving a direction of the operation to approach the reference point P _2, to fast forward, the direction of operation away from the reference point P ₂ In such a case, rewinding may be performed.

  In the above-described first to sixth embodiments, the control unit 18 wants to perform fast-forward or rewind at a constant speed regardless of the speed of the swipe or flick operation. However, the present invention is not limited to this. The faster the speed of the swipe or flick operation, the faster the fast-forward or rewind speed may be.

  In the first to sixth embodiments, the navigation device is used as the video control device. However, the present invention is not limited to this. For example, the video control device may be any device that can reproduce a video, and may be, for example, a drive recorder with a display unit, a smartphone, a tablet, or the like.
