Description

정지영상에 음성데이터를 부가하는 영상기록 방법Image recording method for adding audio data to still images

본 발명은 영상기록 방법에 관한 것으로서, 특히 정지영상에 음성데이터를 부가하는 영상기록 방법에 관한 것이다. VIDEO-CD나 TV 튜너를 장착한 PC에서 동화상을 보면서 사용자가 원하는 장면의 정지영상을 저장하는 영상캐춰보드나 피사체를 디지털영상신호로 저장하는 디지털카메라 등의 보급으로 정지영상의 기록과 삭제를 간편하게 할 수 있게 되었다. 이러한 정지영상은 PC의 하드디스크에 저장된 다른 정지영상과의 편집이 가능하며, 한 예로서 기록 가능한 디스크에 디지털 카메라로 촬상하여 찍은 사진을 모아 가족앨범을 만들 수 있다. 도 1은 이러한 디지털카메라(10)에서 찍은 각각의 정지영상들을 기록한 정지영상 구조를 도시한 것이다. 도 1과 같이 단순히 정지영상의 편집에 한정하지 않고 음성데이터가 부가되면 보다 바람직한 다양한 효과를 얻을 수 있다. 정지영상과 음성데이터를 동시에 재생하기 위해서는 이 두가지 데이터를 믹스하여 도 2와 같이 정지영상과 음성데이터를 조합한 데이터 구조를 가지면 되지만 이러한 데이터 구조에서는 부가된 음성데이터를 다시 기록하거나 삭제하는 것이 곤란하다. 즉, 정지영상과 음성데이터가 믹스된 경우는 이미 정지영상만이 기록된 경우 음성데이터를 삽입하기가 곤란하며, 정지영상에 부가된 음성데이터를 새롭게 갱신하는 것이 어렵고, 또한 정지영상을 제거하게 되면 음성데이터가 같이 삭제되는 문제점이 있었다.The present invention relates to an image recording method, and more particularly to an image recording method for adding audio data to still images. It is easy to record and delete still images by uploading an image capture board that saves the still image of the scene you want while watching a moving image on a PC equipped with a VIDEO-CD or a TV tuner, or a digital camera that stores the subject as a digital video signal . Such still images can be edited with other still images stored on the PC's hard disk, and as an example, a family album can be created by collecting images taken by a digital camera on a recordable disk and taking the pictures. FIG. 1 illustrates a still image structure in which still images taken by the digital camera 10 are recorded. As shown in FIG. 1, when audio data is added not only to the editing of the still image, more various effects can be obtained. In order to simultaneously reproduce the still image and the audio data, it is necessary to mix the two data and have a data structure in which the still image and the audio data are combined as shown in FIG. 2. However, in such a data structure, it is difficult to record or delete the added audio data . That is, when the still image and the audio data are mixed, it is difficult to insert the audio data when only the still image is recorded, and it is difficult to update the audio data added to the still image newly. The voice data is deleted together.

상기 문제점을 해결하기 위해 창출한 본 발명은 디지털 사진기 등에 의해 제작된 매 정지영상마다에 사용자가 원하는 시간동안의 각각의 음성데이터를 부가할 수 있고, 추후에 음성데이터를 갱신하여 다시 기록할 수 있는 정지영상에 음성데이터를 부가하는 영상기록 방법을 제공하는 데 목적이 있다.In order to solve the above problems, the present invention has been made to solve the above-described problems, and it is an object of the present invention to provide an image processing apparatus and method capable of adding each voice data for a desired time to each still image produced by a digital camera, There is provided an image recording method for adding voice data to a still image.

본 발명에서는 하나의 기록매체에 정지영상과 음성데이터를 분리하여 기록하고 이 두 종류 신호의 연관관계와 위치정보를 메모리에 기록해 둔 다음 재생할 때에 이 연관정보를 이용하여 정지영상과 음성데이터를 재생한다. 이러한 기능을 위하여 정지영상과 음성데이터의 기록위치를 알 수 있어야 하고, 음성데이터는 그 길이에 따라 기록매체에 분산되어 기록될 수 있으므로 블록으로 나누어 관리된다.In the present invention, a still image and audio data are separately recorded on one recording medium, and the relationship between the two types of signals and the positional information are recorded in a memory, and then, when reproducing, the still image and audio data are reproduced using the related information . For this function, it is necessary to be able to know the recording position of the still image and the audio data, and the audio data can be distributed and recorded in the recording medium according to the length thereof.

표 1과 같이 매 정지영상마다의 기록시작 위치와 종료위치가 표시되며, 그 다음에는 이 정지영상에 부가된 음성데이터가 있는지의 여부를 나타내는 정보가 표시된다. 음성데이터가 없는 경우에는 음성데이터의 위치정보는 무시되며 음성데이터가 있는 경우에는 음성데이터의 위치정보에 따라 음성데이터를 찾는다. 음성데이터의 위치정보는 음성데이터가 여러 음성데이터블록으로 나누어지는 경우 블록의 시작위치와 종료위치값을 나타내고, 그리고 다음 블록이 있는지의 여부와 다음 블록이 있다면 그 블록의 위치정보의 위치를 나타내는 값들로 이루어진다. 이러한 구조에 따라서 블록들을 연결하여 하나의 음성데이터를 완성하게 되며 맨 마지막 블록인 경우에는 연결블록이 없음을 나타내는 값으로 마지막 블록임을 나타내게 된다.As shown in Table 1, a recording start position and an end position for each still image are displayed. Then, information indicating whether or not there is audio data added to the still image is displayed. If there is no voice data, the location information of the voice data is ignored. If there is voice data, the voice data is searched according to the location information of the voice data. The position information of the voice data indicates the start position and the end position value of the block when the voice data is divided into a plurality of voice data blocks and the values indicating the position of the position information of the next block, . According to this structure, blocks are concatenated to complete one voice data. In the case of the last block, a value indicating that there is no concatenated block is indicated as the last block.

여기서, 정지영상의 시작과 종료위치는 섹터번호를 나타내며 4바이트로 할당된다. 또한, 음성데이터 유무는 예로서 0값이면 정지영상에 해당되는 음성데이터가 없음을 나타내고 1값이면 해당되는 음성데이터가 있음을 나타내며, 음성데이터 정보위치는 현재 바이트에서 정보위치까지의 상대 바이트수를 나타낸다.Here, the start and end positions of the still image indicate the sector number and are allocated to 4 bytes. The presence or absence of audio data indicates that there is no audio data corresponding to the still image if the value is 0, and indicates that the corresponding audio data exists if the value is 1. If the value is 1, the audio data information position indicates the relative byte number from the current byte to the information position .

이러한 구조는 음성데이터의 크기가 변하더라도 변화된 블록들의 위치 정보만을 계속해서 갱신하면 일관된 구조가 유지되는 장점이 있다.This structure is advantageous in that, even if the size of voice data is changed, a consistent structure is maintained by continuously updating only the location information of changed blocks.

기록된 정지영상과 음성데이터를 재생할 때는 다음과 같은 규칙을 따른다. 정지영상에 부가된 음성데이터가 없는 경우에는 일정한 시간이 경과하거나 사용자가 다음 정지영상을 재생하라는 신호를 입력하면 다음 정지영상을 재생한다. 음성데이터가 있는 경우에는 먼저 정지영상을 재생하고 그 다음 음성데이터의 위치를 추적하여 음성데이터를 재생한다. 음성데이터의 재생이 모두 종료되거나 도중에 사용자가 다음 정지영상을 재생하라는 신호를 입력하면 다음 정지영상을 재생한다.The following rules apply when playing recorded still images and audio data. When there is no audio data added to the still image, if a predetermined time elapses or when the user inputs a signal to reproduce the next still image, the next still image is reproduced. If there is audio data, the still image is first reproduced and the position of the next audio data is tracked to reproduce the audio data. When the reproduction of the audio data is completed or the user inputs a signal to reproduce the next still image, the next still image is reproduced.

도 3a 및 도 3b는 본 발명에 따른 정지영상만을 기록한 경우에서의 위치정보의 구조와 기록되는 정지영상의 기록구조를 도시한다.3A and 3B illustrate a structure of position information and a recording structure of a still image to be recorded in the case of recording only a still image according to the present invention.

도 3a의 위치정보의 구조에 나타나는 위치0 및 위치3은 표 1에 기재된 바와 같이 각각 정지영상1 시작위치와 정지영상1의 종료위치를 나타내며, 음성데이터1의 블록은 부가되어 있지 않기 때문에 음성데이터1의 유무를 표시하는 값은 0이며, 음성데이터1 정보위치에 대한 값 또한 0이 된다.As shown in Table 1, position 0 and position 3 in the structure of the position information in Fig. 3A indicate the start position of the still image 1 and the end position of the still image 1, respectively, 1 is 0, and the value for the audio data 1 information position is also 0.

도 4는 본 발명에 적용되는 정지영상에 음성데이터를 부가하는 장치를 설명하기 위한 블록도이다.4 is a block diagram for explaining an apparatus for adding voice data to a still image according to the present invention.

도 4에서, 디지털카메라에서 촬상되어 순차적으로 정지영상저장부(45)에서 저장된 정지영상에 음성데이터를 부가하기 위해서 사용자가 음성녹음버튼(41)을 누르면 마이컴제어부(44)는 유입되는 음성데이터를 기록한다. 이때, 마이컴제어부(44)에 의해 정지영상저장부(45)에서 리드되어 기록부(46)의 미도시된 기록매체에 저장된 정지영상들의 데이터와는 별도의 공간에 유입된 음성데이터가 기록되며, 음성데이터의 기록이 종료되면 정지영상의 위치를 기록한 정보에 부가된 음성데이터의 위치를 기록한 정보가 추가된다. 음성데이터의 종료는 음성녹음 해제버튼(42)을 누르거나 다음 정지영상의 재생을 위한 정지영상재생버튼(43)을 누르거나 하면 된다. 다음 정지영상재생신호가 입력된 경우에는 현재 기록된 음성데이터의 기록을 종료하고 다음 정지영상의 재생을 한 다음 두 번째 영상에 부가된 음성데이터를 계속하여 기록한다. 최종적으로 음성녹음 해제신호가 입력되면 두 번째 정지영상의 위치정보에 음성데이터의 위치정보가 추가되어 기록된다.4, when the user presses the voice recording button 41 in order to add voice data to the still image stored in the still image storage unit 45 captured by the digital camera, the microcomputer control unit 44 controls the microcomputer control unit 44 Record. At this time, the audio data that is read by the microcomputer control unit 44 in the still image storage unit 45 and entered into a space separate from the data of the still images stored in the recording medium (not shown) of the recording unit 46 is recorded, When the recording of the data ends, information recording the position of the audio data added to the information recording the position of the still image is added. The voice data can be terminated by pressing the voice recording release button 42 or by pressing the still image reproduction button 43 for reproducing the next still image. When the next still image reproduction signal is input, the recording of the currently recorded audio data is terminated, the next still image is reproduced, and the audio data added to the second image is continuously recorded. When the voice recording cancellation signal is finally input, the location information of the voice data is added to the location information of the second still image.

도 5a 및 도 5b는 본 발명에 따른 정지영상에 음성데이터가 부가되어 기록시에 위치정보의 구조와 기록되는 각신호의 기록구조를 도시한다.5A and 5B show the structure of the position information and the recording structure of each signal to be recorded upon addition of audio data to the still image according to the present invention.

도 5a의 위치정보의 구조에 나타나는 위치0(50) 및 위치3(51)은 표 1에 기재된 바와 같이 각각 정지영상1 시작위치와 정지영상1 종료위치를 나타내며, 음성데이터1 및 2 블록이 정지영상에 부가되어 있기 때문에 음성데이터1 유무에 대한 값은 1이 되며, 음성데이터1 정보위치는 어드레스 POS1으로 되어있다. 또한 어드레스 POS1에는 음성데이터1 블록의 시작위치와 종료위치의 값과 연결블록 유무의 값과 연결된 음성데이터블록의 정보위치 즉 어드레스가 기록되어 있다. 즉, 어드레스 POS1에는 연결블록의 유무를 나타내는 0값으로 설정되어 있고 연결된 음성데이터블록의 정보위치는 POS3의 어드레스로 기록되어 있다.The position 0 (50) and the position 3 (51) shown in the structure of the position information of FIG. 5A indicate the start position of the still image 1 and the end position of the still image 1, respectively, as shown in Table 1, The value for the presence / absence of the audio data 1 is 1, and the position of the audio data 1 information is the address POS1. In the address POS1, the values of the start and end positions of one block of voice data and the information positions or addresses of the voice data blocks connected to the values of the presence / absence of connection block are recorded. In other words, the address POS1 is set to a value of 0 indicating the presence of a connection block, and the information position of the connected audio data block is recorded at the address of POS3.

따라서, 위치정보의 구조는 우선 정지영상이 기록매체의 어느 부분에 위치하는가에 대한 정보가 시작위치와 종료위치가 기록되며, 다음은 이 정지영상에 부가된 음성데이터의 존재여부가 기록되고 음성데이터가 존재한다면 그 음성데이터의 위치정보가 어디에 기록되어 있는지를 나타내는 어드레스(POS1 내지 POS3)가 기록된다. 이것을 한 단위로 하여 기록된 모든 정지영상들에 대한 정보가 기록된 후 음성데이터에 대한 위치정보가 기록되며, 이 위치정보는 정지영상과는 다르게 분산되어 음성데이터블록으로 나누어진 형태로 기록되어 질 수 있다. 우선 제일 처음의 음성데이터블록의 시작 위치와 종료 위치가 표시되고, 다음은 연속된 블록의 존재여부를 나타내며 만일 연속된 블록이 있다면 그 블록의 위치에 대한 정보가 어디에 기록되어 있는가 하는 정보가 기록된다. 이러한 형식으로 기록되어 블록으로 나누어진 음성데이터의 위치정보가 분산되어 기록될 수 있기 때문에 음성데이터의 길이에 관계없이 정지영사에 부가 또는 갱신하여 기록이 가능하다.Therefore, in the structure of the position information, the start position and the end position of information on the position of the still image on the recording medium are recorded. Next, the presence or absence of the audio data added to the still image is recorded, (POS1 to POS3) indicating where the positional information of the voice data is recorded are recorded. The position information of the audio data is recorded after all of the recorded still images are recorded as one unit. The position information is dispersed and divided into voice data blocks differently from the still image. . First, the start position and the end position of the first audio data block are displayed. Next, it indicates whether there is a continuous block. If there are consecutive blocks, information on where the information of the position of the block is recorded is recorded . Since the positional information of audio data divided into blocks is recorded in this format, it can be recorded and added to or reproduced from the still projection regardless of the length of the audio data.

본 발명에 의한 정지영상에 음성데이터를 부가하는 영상기록 방법은 매 정지영상의 시작과 종료위치값을 기록하고 해당 정지영상에 대한 음성데이터의 존재 여부와 음성데이터의 위치정보에 따라 음성데이터를 별도로 기록함으로써, 음성데이터를 길이에 제한을 받지 않고 정지영상에 기록할 수 있고, 기록한 다음 이미 부가되어 기록된 기존 음성데이터보다 길거나 짧은 길이의 음성데이터로 교체할 수 있다.According to an aspect of the present invention, there is provided an image recording method for recording audio data to a still image by recording the start and end position values of each still image and separately extracting audio data according to the presence or absence of audio data for the still image, By recording, the audio data can be recorded on the still image without being limited in length, and can be replaced with audio data having a length longer or shorter than the existing audio data already recorded after being recorded.
