9 is a flowchart illustrating a first embodiment of a video recording method of a mobile communication terminal according to the present invention. In this case, FIG. 9 illustrates a method for setting a section during video recording and relates to a method for setting a section according to a change in brightness value or frame rate.

The camera is driven (S200), and a video is captured according to the setting (S205).

When a moving image is captured, light incident through a camera lens is converted into an electrical image signal by an image sensor and input, and the image signal is converted to generate moving image data in units of frames.

At this time, the brightness value between the frames is calculated based on the input image signal, and the exposure time of the image sensor is varied according to the brightness value. Here, the exposure time is controlled by changing the number of frames per second, that is, the frame rate of the moving image. It becomes (S210).

The change amount between the frames is calculated for any one of the brightness value and the frame rate as described above, and the change amount is compared with the reference value (S215). Here, the change amount of the brightness value is compared with the reference brightness value, and the change amount of the frame rate is compared with the reference frame rate.

If the amount of change in brightness / frame rate is greater than or equal to the reference value, the section is automatically set at the current position of the video data (S220).

Here, the section setting of the video data is set based on the current playback position and the playback time on the basis of the video recording start time, and is stored as section setting data.

In this case, the section setting data may be set by extracting information on a play position or a play time for each position where the section is set, or insert section information at a corresponding position of the video data. In addition, section setting may be performed by inserting section setting information into a header of the video data.

When the section setting is completed or the change amount of brightness / frame rate is less than the reference value, the video is continuously photographed, and the video shooting and section setting as described above are repeatedly performed (S205 to S220).

If a shooting end command is input during the video shooting (S225), the shooting ends, and the set section information is stored together with the captured video data (S230).

10 is a flowchart illustrating a second embodiment of a video recording method of a mobile communication terminal according to the present invention.

A second embodiment of a video data photographing and section setting method of a mobile communication terminal according to the present invention is as follows.

When the camera is driven and video recording starts, video signals are input to generate video data (S300).

The brightness value or frame rate of the input video signal is measured (S305), and it is determined whether the measured brightness value or frame rate is included in a predetermined range (S310).

Here, the brightness value is divided into one or more ranges, the brightness level is set for each range, and the brightness level is set by determining a range including the brightness value of the input frame.

In the case of the frame rate, the frame rate is set for each range by dividing the frame rate into one or more ranges based on the maximum frame rate of the camera that can be set. When the current frame rate is included in the predetermined range, the frame rate level corresponding thereto is set.

For example, when the section is set in the video data based on the frame rate, it is as shown in FIG.

11 is an exemplary view illustrating an embodiment according to level setting of a mobile communication terminal according to the present invention.

As shown in (a) of FIG. 11, when the maximum frame rate of a video photographed through the camera of the mobile communication terminal is 30, for example, the frame rate is divided into five ranges based on the maximum frame rate 30. Specify. Here, the number of frame rate levels is not limited to the drawings and may vary according to settings.

When the camera is operated and an image signal is input from the image sensor, the brightness value is calculated, and the frame rate of the image sensor is variably controlled according to the brightness value.

At this time, when entering the underground parking lot from the outside, the brightness of the surroundings is rapidly changed. Here, if the frame rate is 15 from the outside and the internal frame rate is 5 when entering the underground parking lot, the frame rate level is 3 from the outside. When entering the underground parking lot, the frame rate level is changed to one.

Since the frame rate level varies from 3 to 1, a section is set in the video data.

As illustrated in (b) of FIG. 11, the frame rate level may be set based on the maximum frame rate that can be captured by the camera. Here, the number of frame rate levels is not limited to the drawings and may vary according to settings.

That is, the frame rate level may be set by 20% based on the maximum frame rate (MFR). For example, when the maximum frame rate (MFR) is 60, the frame rate 0 or more and less than 12 (ie, 60/5) may be set. It is possible to set the first level, the second level in the case of 12 or more and 24, the third level in the case of 24 or more and less than 36, the fourth level in the case of 36 or more and less than 48 and the fifth level in the case of a frame rate of 48 or more.

By specifying one or more brightness levels as described above, the brightness level may be set according to the brightness value of the input frame, and a section may be set in the video data when the brightness level is variable.

A third embodiment of the video data photographing and section setting method of the mobile communication terminal according to the present invention is as follows.

12 is a flowchart illustrating a third embodiment of a video recording method of a mobile communication terminal according to the present invention.

As shown in FIG. 12, when the camera is operated to capture a video, the brightness value of the frame is calculated according to the input video signal, and the frame rate is variably controlled (S400 to S410).

Here, the brightness value or the frame rate of the frame of the video data is measured to set the brightness level or the frame rate level for the brightness value and determine whether the brightness level or the frame rate level is variable (S410).

If it is determined that the brightness level is increased or decreased and is variable, the variation amount of the brightness value is calculated and compared with the reference brightness value. If the frame rate level is determined to be variable, the variation amount of the frame rate is calculated to calculate the reference frame. It compares with a rate (S415).

In this case, when the brightness value is equal to or greater than the reference brightness value or the amount of change in the frame rate is equal to or greater than the reference frame rate, a section is set in the video data (S420).

On the other hand, if the brightness level or the frame rate level is maintained, or if the variation of the brightness value / frame rate is less than the reference brightness value / reference frame rate, the video is captured without setting a separate section (S410, S415, S400).

For example, as shown in FIG. 11A, the frame rate level is set. When the reference frame rate is 6, the section setting according to the change of the frame rate is performed as follows.

When the frame rate varies from 11 to 13, it can be seen that the frame rate level for frame rate 11 is 2 and the frame rate level for frame rate 13 is 3, so that the level of frame rate is variable.

Here, even if the frame rate level is varied as described above, the variation amount of the frame rate is calculated and compared with the reference frame rate value. When the frame rate is changed from 11 to 13 as described above, since the change amount is 2, the reference frame rate value is 6 or less, and thus video recording is continuously performed without setting a section in the video.

If a section is set in the video data as described above and the video data is stored, the video data is reproduced as follows.

FIG. 13 is a flowchart illustrating a first embodiment of a video reproducing method of a mobile communication terminal according to the present invention, and FIG. 14 is a flowchart illustrating a section moving method when reproducing a video of a mobile communication terminal according to the present invention.

When a section movement command is input during video playback, for example, when a direction key, a side key, and a jog button are operated (S510), the section information set in the video is searched (S515).

Based on the retrieved section information, the playback position is moved from the current playback position to the previous section or the next section according to the input section movement command (S520).

At this time, the playback position is moved to the beginning of the selected section.

If the playback position is changed as described above, the video is played from the selected section (S525).

In this case, the video playback method according to the section movement command input will be described in detail as follows.

As shown in FIG. 14, when an input means such as a direction key, a moving key, a site key, a jog button, a wheel, or the like is operated according to the type of an input unit provided, a section movement command is input (S600). Hereinafter, the direction keys will be described as an example.

When the direction key is input, the section information set in the video data being played is searched. The information on the entire section can be searched, and the specific section can be searched according to the type of the direction key input.

That is, when the left direction key is input, the previous section is searched based on the current playback position of the video data (S605), and the playback position is moved to the first position of the previous section (S625).

When the right direction key is input, the next section is searched based on the current playback position (S610), and the playback position is moved to the first position of the next section (S625).

If the playback position is moved to the previous section or the next section as described above, the video data is played from the selected section (S635).

At this time, when the left or right direction key is continuously input, the section set in the video data is searched continuously to change the playback position, and the video is played from the section.

On the other hand, when the up and down arrow keys are input, the previous video data or the next video data other than the current video data is searched (S615, 620), the video data to be played back is changed (S630), and the video data is played back. (S635).

Here, the direction key as described above may be changed to enable fast forward / rewind, and may also be set to allow movement to the first section / last section.

That is, when the up / down direction keys are operated as described above, the play position is moved to the first section / last section, or the fast forward / rewind may be performed by changing the playback speed.
