"영상기록장치"는 피사체의 촬영영상을 탑재된 저장매체에 기록하는 장치를 말한다. 또한, 영상기록장치는 저장매체에 기록되어 있는 데이터를 구비된 디스플레이를 통해 재생이 가능하다.The "image recording device" refers to a device for recording a photographed image of a subject on a mounted storage medium. In addition, the image recording apparatus can be reproduced through a display provided with data recorded on the storage medium.

또한, 영상기록장치는 메뉴의 설정을 통해 SP 및 LP 기록방식 중 어느 하나를 설정하여, 고정된 기록속도(recording rate)로 촬영되는 영상을 저장매체에 기록이 가능하다. In addition, the image recording apparatus can set any one of the SP and LP recording method through the setting of the menu, so that the image recorded at a fixed recording rate can be recorded on the storage medium.

If it exceeds, it is possible to shoot only a part of the image to be taken, or inconvenience of having to replace the storage medium during the shooting. Here, the recordable time is detected in accordance with a preset recording speed by checking the remaining amount of the loaded storage medium.

이에, 기록희망시간이 저장매체의 잔량에 따른 기록가능시간을 초과할 경우, 기록속도를 가변하여 저장매체의 교체 없이 기록가능시간을 연장할 수 있는 기술이 요청된다.Therefore, if the recording desired time exceeds the recordable time according to the remaining amount of the storage medium, a technique for extending the recordable time without changing the storage medium by changing the recording speed is required.

따라서, 본 발명의 목적은, 기록희망시간이 저장매체의 잔량에 따른 기록가능시간을 초과할 경우에 저장매체의 교체 없이 기록가능시간을 연장하기 위해, 기록희망시간에 따라 기록속도를 가변하는데 목적이 있다.Accordingly, an object of the present invention is to change the recording speed according to the recording desired time in order to extend the recordable time without replacing the storage medium when the recording desired time exceeds the recordable time according to the remaining amount of the storage medium.

It is preferable to include.

이하에서는 도면을 참조하여 본 발명을 보다 상세하게 설명한다.Hereinafter, with reference to the drawings will be described the present invention in more detail.

도 1은 본 발명의 일 실시예에 따른 기록희망시간에 따라 기록속도를 가변하는 영상기록장치의 설명에 제공되는 블럭도이다.1 is a block diagram provided to explain an image recording apparatus whose recording speed is varied according to a recording desired time according to an embodiment of the present invention.

이하에서는, 본 발명이 적용 가능한 대표적인 실시 예인 캠코더를 예로 들어 설명한다.Hereinafter, a camcorder, which is a representative embodiment to which the present invention is applicable, will be described as an example.

도 1을 참조하면, 캠코더(100)는 촬영부(110), 신호처리부(120), 코덱부(130), 기록재생부(140), 디스플레이(150), 입력부(160), 검출부(170), 비교연산부(180), 제어부(190) 및 컨트롤러(195)를 구비한다.Referring to FIG. 1, the camcorder 100 includes a photographing unit 110, a signal processing unit 120, a codec unit 130, a recording and playback unit 140, a display 150, an input unit 160, and a detection unit 170. And a comparison operation unit 180, a control unit 190, and a controller 195.

다만, 캠코더(100) 내에 포함될 수 있는 기타의 구성요소는 도면에서 배제하고 본 발명을 설명함에 있어 필요한 구성요소만을 도시하는 것으로 한다.However, other components that may be included in the camcorder 100 are excluded from the drawings and only those components necessary for describing the present invention will be shown.

촬영부(110)는 구비된 렌즈(미도시)를 통해 촬영대상의 동영상 및 정지영상 중 어느하나를 촬영하여 영상신호를 생성한다.The photographing unit 110 generates an image signal by photographing any one of a moving image and a still image of a photographing target through a provided lens (not shown).

신호처리부(120)는 촬영부(110)가 생성한 영상신호를 전달받아 가공처리한다.The signal processor 120 receives and processes the image signal generated by the photographing unit 110.

코덱부(130)는 가공처리된 영상신호를 압축한다. 또한, 코덱부(130)는 컨트 롤러(195)의 제어하에 압축률을 조절하여, 가공처리된 영상신호가 가변된 기록속도로 저장매체에 기록되도록 한다. 이에 대한 상세한 설명은 후술하기로 한다.The codec unit 130 compresses the processed video signal. In addition, the codec unit 130 adjusts the compression rate under the control of the controller 195 so that the processed image signal is recorded on the storage medium at a variable recording speed. Detailed description thereof will be described later.

기록재생부(140)는 코덱부(130)로부터 전달받은 압축된 영상신호를 탑재된 저장매체에 기록하는 역할을 한다. 또한, 기록재생부(140)는 탑재된 저장매체에 기록된 영상을 재생하는 역할을 한다.The recording and reproducing unit 140 records the compressed video signal received from the codec unit 130 on the mounted storage medium. In addition, the recording and playback unit 140 plays a role of playing back the image recorded in the mounted storage medium.

디스플레이(150)는 저장매체에 기록된 영상을 사용자가 볼 수 있도록 디스플레이한다. 또한, 디스플레이(150)는 촬영부(110)가 촬영대상을 촬영 시, 코덱부(130)로부터 압축된 영상신호를 전달받아 사용자가 디스플레이(150)를 보면서 촬영대상을 촬영할 수 있는 인터페이스를 제공한다.The display 150 displays an image recorded on the storage medium for the user to view. In addition, the display 150 receives an image signal compressed from the codec unit 130 when the photographing unit 110 captures a photographing target, and provides an interface for the user to photograph the photographing target while viewing the display 150. .

입력부(160)는 촬영대상의 기록희망시간을 입력받는다. 여기서, 기록희망시간이란, 입력부(160)가 사용자로부터 입력받는 촬영대상의 동영상 촬영에 소요될 예상시간을 말한다. 여기서, 촬영대상이 정지영상일 경우에는 입력부(160)가 사용자로부터 기록희망매수를 입력받는다.The input unit 160 receives a recording desired time of the photographing target. Here, the recording desired time refers to an estimated time that the input unit 160 takes to capture a moving picture of a shooting target received from a user. Here, when the photographing target is a still image, the input unit 160 receives the number of desired recordings from the user.

검출부(170)는 탑재된 저장매체의 잔량을 체크하여 기설정된 기록속도에 따른 저장매체의 기록가능시간을 검출한다. 여기서, 기록가능시간이란, 저장매체의 잔량에 기설정된 기록속도로 기록시 소요되는 시간을 만한다.The detector 170 checks the remaining amount of the mounted storage medium and detects a recordable time of the storage medium according to a preset recording speed. Here, the recordable time refers to the time required for recording at a recording speed preset to the remaining amount of the storage medium.

다시 말하면, 입력부(160)로부터 기록희망시간이 입력되면, 검출부(170)는 기록재생부(140)를 통해 탑재된 저장매체의 잔량을 자동으로 체크하여, 기설정된 기록속도에 따른 저장매체의 기록가능시간을 검출한다.In other words, when a recording desired time is input from the input unit 160, the detection unit 170 automatically checks the remaining amount of the storage medium loaded through the recording and reproducing unit 140, and records the storage medium according to the preset recording speed. The possible time is detected.

비교연산부(180)는 기록희망시간과 기록가능시간을 비교하여 시간차를 연산 한다.The comparison operation unit 180 calculates a time difference by comparing the recording desired time with the recordable time.

다시 말하면, 비교연산부(180)는 입력부(160)를 통해 입력된 기록희망시간과 검출부(170)가 검출한 기설정된 기록속도 하에서 저장매체의 잔량에 따른 기록가능시간을 상호 비교하여 시간의 대소를 연산한다.In other words, the comparison operation unit 180 compares the recording desired time input through the input unit 160 with the recordable time according to the remaining amount of the storage medium under the preset recording speed detected by the detection unit 170, and compares the magnitude of the time. Calculate

제어부(190)는 비교연산부(180)의 연산 결과, 기록희망시간이 기록가능시간을 초과할 경우, 기록가능시간이 기록희망시간에 맞도록 기설정된 기록속도를 가변하여 조절한다. If the recording desired time exceeds the recordable time as a result of the operation of the comparison operation unit 180, the controller 190 adjusts and adjusts the preset recording speed so that the recordable time matches the record desired time.

다시 말하면, 제어부(190)는 기설정된 기록속도 하에서 탑재된 저장매체의 잔량에 따른 기록가능시간이 사용자가 요청한 기록희망시간보다 부족할 경우에, 촬영대상의 촬영 도중에 저장매체를 교체하지 않아도 되도록, 기록속도를 가변하여 저장매체의 기록가능시간이 기록희망시간보다 커지도록 조절한다.In other words, when the recordable time according to the remaining amount of the storage medium loaded under the preset recording speed is shorter than the recording desired time requested by the user, the control unit 190 does not need to replace the storage medium during the shooting of the shooting target. The speed is varied so that the recordable time of the storage medium is larger than the recording desired time.

컨트롤러(195)는 제어부(190)에 의해 가변된 기록속도에 따라 코덱부(130)를 제어한다.The controller 195 controls the codec unit 130 according to the recording speed variable by the controller 190.

다시 말하면, 컨트롤러(195)는 코덱부(130)의 압축률을 제어하여 신호처리부(120)에 의해 가공처리된 영상신호가 제어부(190)에 의해 가변된 기록속도로 저장매체에 기록되도록 한다.In other words, the controller 195 controls the compression ratio of the codec unit 130 so that the image signal processed by the signal processor 120 is recorded on the storage medium by the controller 190 at a variable recording speed.

도 2는 본 발명의 일 실시예에 따른 기록희망시간에 따라 기록속도를 가변하는 방법의 설명에 제공되는 흐름도이다.2 is a flowchart provided to explain a method of varying a recording speed according to a recording desired time according to an embodiment of the present invention.

도 1 및 도 2를 참조하면, 입력부(160)가 촬영대상의 기록희망시간을 입력받는다(S210). 여기서, 촬영대상이 정지영상일 경우에는 입력부(160)가 사용자로부터 기록희망매수를 입력받는다.1 and 2, the input unit 160 receives a recording desired time of a photographing target (S210). Here, when the photographing target is a still image, the input unit 160 receives the number of desired recordings from the user.

검출부(170)가 탑재된 저장매체의 잔량을 체크하여 기설정된 기록속도에 따른 저장매체의 기록가능시간을 검출한다(S220).The detector 170 checks the remaining amount of the mounted storage medium to detect a recordable time of the storage medium according to the preset recording speed (S220).

다시 말하면, 입력부(160)로부터 기록희망시간이 입력되면, 검출부(170)는 기록재생부(140)를 통해 탑재된 저장매체의 잔량을 자동으로 체크하여, 저장매체의 잔량에 기설정된 기록속도로 기록시 소요되는 시간인 기록가능시간을 검출한다.In other words, when a recording desired time is input from the input unit 160, the detection unit 170 automatically checks the remaining amount of the storage medium loaded through the recording / reproducing unit 140, and at the recording speed preset to the remaining amount of the storage medium. A recordable time, which is a time required for recording, is detected.

비교연산부(180)가 기록희망시간과 기록가능시간을 비교하여 시간차를 연산한다(S230).The comparison operation unit 180 calculates a time difference by comparing the recording desired time with the recordable time (S230).

비교연산부(180)의 비교연산결과 기록희망시간이 기록가능시간을 초과할 경우(S240), 제어부(190)가 기록가능시간이 기록희망시간에 맞도록, 기설정된 기록속도를 가변하여 기록가능시간을 조절한다(S250).When the result of the comparison operation of the comparison operation unit 180 exceeds the recordable time (S240), the controller 190 changes the recordable time by varying the preset recording speed so that the recordable time corresponds to the record desired time. To adjust (S250).

다시 말하면, 제어부(190)는 기설정된 기록속도 하에서 탑재된 저장매체의 잔량에 따른 기록가능시간이 사용자가 요청한 기록희망시간보다 부족할 경우에, 촬영대상의 촬영 도중에 저장매체를 교체하지 않아도 되도록, 기록속도를 가변하여 저장매체의 기록가능시간이 기록희망시간보다 커지도록 조절한다.
컨트롤러(195)가 가변된 기록속도에 따라 코덱부(130)를 제어하여 촬영대상이 기록되도록 한다(S260).In other words, when the recordable time according to the remaining amount of the storage medium loaded under the preset recording speed is shorter than the recording desired time requested by the user, the control unit 190 does not need to replace the storage medium during the shooting of the shooting target. The speed is varied so that the recordable time of the storage medium is larger than the recording desired time.
The controller 195 controls the codec unit 130 according to the variable recording speed so that the photographing target is recorded (S260).

다시 말하면, 컨트롤러(195)는 코덱부(130)의 압축률을 제어하여 신호처리부(120)에 의해 가공처리된 영상신호가 제어부(190)에 의해 가변된 기록속도로 저장매체에 기록되도록 한다.In other words, the controller 195 controls the compression ratio of the codec unit 130 so that the image signal processed by the signal processor 120 is recorded on the storage medium by the controller 190 at a variable recording speed.

여기서, S240단계에서, 비교연산부(180)의 비교연산결과 기록희망시간이 기록가능시간 이하일 경우에는, 제어부(190)의 제어하에 컨트롤러(195)가 기설정된 기록속도에 따라 코덱부(130)를 제어하여 촬영대상이 기록되도록 한다(S270).Here, in step S240, when the comparison calculation result of the comparison operation unit 180 is less than the recordable time, the controller 195 controls the codec unit 130 according to the preset recording speed under the control of the controller 190. By controlling the recording to be recorded (S270).
