Description

Shooting control method and device of an image acquisition device {PHOTOGRAPH CONTROLLING METHOD AND APPARATUS FOR IMAGE AQUISITION EQUIPMENT}

The present invention relates to an image acquisition device, and more particularly, to a shooting control method and apparatus.

Nowadays, people are getting better and bi-weekly, so many people are getting out to the outdoors, and outdoor scenes such as events and games are recorded and stored in video or still images.

In general, a video is photographed using a camcorder.

A photographing process in a conventional camcorder will be described with reference to the operation flowchart of FIG. 1.

First, when a video is to be recorded, the video is captured by using the video menu key.

At this time, the image data input from the camera sensor is stored in the video buffer and is stored in the video buffer through video encoding every time one frame is obtained.

After the video shooting is completed, the video data temporarily stored in the video buffer is stored in the ROM.

On the contrary, if you want to take a still image, select the take a menu to shoot the desired still image.

In this case, when taking a picture, the image data input from the camera sensor is stored in the video buffer and stored in the ROM through still image encoding every 1 frame.

If you want to take a picture while shooting a video, you must end the current video recording operation, return to the standby screen, and go back to the photo menu to set up taking a picture. At this time, the video buffer is initialized to delete all image data temporarily stored during video recording.

Accordingly, when the photographing operation is performed, the image data input from the camera sensor is stored in the video buffer and the still image encoding process is performed every time one frame is stored in the ROM. In this case, a video buffer is used to temporarily store still images.

In addition, if a video is taken again while taking a picture, the video is taken in the same process as the video recording operation.

However, in the related art, two menus cannot be performed at the same time because menus for video shooting and photo shooting are divided.

Therefore, if there is an image that you want to take a picture while shooting a video, it is necessary to press the key again several times in order to set the shooting mode again after exiting the video mode that was being recorded. There is a disadvantage in that it can not take a picture of the scene.

Accordingly, the present invention, in order to improve the conventional problems, in the image acquisition device, the method of controlling the shooting of the image acquisition device created so that it is possible to shoot still images with a single key input without stopping the video recording operation during the video recording And to provide a device.

According to an aspect of the present invention, there is provided a method of capturing moving images of an image capturing apparatus, the method including determining whether still image shooting is set while moving a movie, and stopping the recording separately from the moving image buffer when still image shooting is set. Simultaneously storing image data in the image buffer; and storing image data of the one frame by still image encoding the image data of the one frame when the image data of one frame is stored in the still image buffer.

In addition, the present invention, in the image acquisition device to perform the above process, a memory for storing the captured video and still image data, a video buffer for storing the image data of video recording, and stops when video recording is in progress When a specific key for image capturing is pressed, a still image buffer for storing one frame of image data currently captured separately from the video buffer; and if one frame of image is stored in the still image buffer, the image data is still encoded. And a video encoder for storing a still image encoder in a memory and a video encoder for encoding the image data stored in the video buffer and storing the image data in the memory when video recording is completed.

Hereinafter, the present invention will be described in detail with reference to the drawings.

An embodiment of the present invention will be described a recording process in the camcorder (camcorder).

FIG. 2 is a block diagram of a photographing control device according to an exemplary embodiment of the present invention. As shown in FIG. 2, a camera sensor 210 converting reflected light of a subject into image data, and temporarily storing a moving image and a still image upon pressing a specific key A buffer unit 220 for displaying images, an LCD 230 for displaying captured images and a menu screen, a memory unit 250 for storing moving images and still images, and image data from the camera sensor 210. Is transmitted to the buffer unit 220 and receives a video or still image of one frame for storage in the memory unit 250 from the buffer unit 220 and encoded, and displays a photographed image on the LCD 230 The image processor 240 controls the image processor 240 to store a still image in the buffer unit 220 when a specific key is pressed during video recording, and enters the image processor 240 from the image processor 240. A still image of one frame to be encoded is composed of a controller 260 for storage in the memory unit 250.

The buffer unit 220 includes a video buffer 221, a video buffer 222, and a still image buffer 223.

The memory unit 250 includes a nonvolatile memory for storing image data even when the power is turned off.

Referring to the operation and effect of the embodiment of the present invention configured as described above are as follows.

First, when a user presses a video menu key, image data input from the camera sensor 210 is transferred to the buffer unit 220 by the image processor 230 and stored in the video buffer 222 via the video buffer 221. And at the same time is displayed on the LCD (240).

Afterwards, when the video recording ends, the image processor 230 encodes the image data transferred from the video buffer 222 by the video encoder 231.

Accordingly, the controller 260 stores the video data encoded by the image processor 230 in the memory 250.

On the other hand, if there is a scene that you want to keep as a picture during video recording, the user presses a specific key for taking a still picture, that is, taking a picture.

In this case, the controller 260 recognizes that a specific key for taking a picture is pressed and notifies the image processor 230, and the image data is transmitted to the buffer unit 220 by the image processor 230, thereby transmitting a video buffer. Both the video buffer 222 and the still image buffer 223 are stored via 221.

Then, when the image data stored in the buffer unit 220 becomes one frame, the image data of the one frame is read from the still image buffer 223 to the image processor 230 and the image processor 230 is a still image encoder. 232 encodes the image data of the one frame.

Accordingly, the controller 260 stores the still image data encoded by the image processor 230 in the memory 250.

The still image capturing process is executed every time a specific key is pressed during video recording, and the user is notified by displaying on the alarm or LCD 240 that the still image is stored.

The moving image data is continuously stored in the moving image buffer 222 while still image shooting is in progress.

Afterwards, when the video recording ends, the image processor 230 encodes the image data transferred from the video buffer 222 by the video encoder 231.

Accordingly, the controller 260 stores the video data encoded by the image processor 230 in the memory 250.

The moving image and the still image stored in the memory 250 are distinguished by being assigned a unique identification number, and each moving image is also distinguished by a unique identification number.

As described in detail above, the present invention has the effect of providing convenience and satisfaction to the user by enabling the user to take a picture by pressing a single key without ending the video recording when the user wants to leave a specific image as a picture during video recording.
