[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a communication terminal device capable of transmitting a moving image, and more particularly to a portable terminal device that captures a still image from a moving image and records and saves it.
[0002]
[Prior art]
As a technique for capturing and storing still images from a conventional moving image, for example, in the video camera field, as shown in Japanese Patent Laid-Open No. 05-292444, a still image recording switch is configured in a two-stage system, and when pressed to a half-pressed position, the moving image The signal for one image is taken into the memory as a still image signal from the signal, and the captured still image signal is displayed on the viewfinder so that it can be confirmed. When the switch is fully depressed, the still image signal taken into the memory A video camera has been proposed for recording video on a tape.
[0003]
[Problems to be solved by the invention]
However, in the conventional technology, only a still image at the time of pressing the switch is stored in the memory. Therefore, the stored still image is stored such that the switch pressing timing is shifted and an unnecessary subject enters the main subject, or the image is not an image at the intended moment. If a satisfactory result is not obtained, there is a problem that there is no other way but to try again or give up.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in more detail with reference to the drawings.
FIG. 1 is a configuration diagram of an embodiment of the present invention. In the figure, reference numeral 1 denotes a data receiving unit which transfers image data received via wireless or wired to a moving image buffer and a processing unit. 2 is a video buffer that temporarily stores video data for a certain time (frame). A processing unit 3 decodes the image data from the data receiving unit 1 and the moving image buffer 2 and converts it into displayable data. A display unit 4 displays moving image data and still image data. 4 is a still image buffer that temporarily stores screen display data. 5 is a still image memory for permanently recording still image data selected by the user.
[0007]
In such a configuration, the moving image data received by the data receiving unit 1 is decoded by the processing unit 3 and displayed as a moving image on the display unit 4, and the moving image data is stored in the moving image buffer 2. At this time, the moving image buffer 2 sequentially stores new data, and when the buffer becomes full, the moving image data stored in the past is erased and new moving image data is continuously stored.
[0008]
If the storage switch is turned on while the moving image data is being received, the data flow from the data receiving unit 1 through the processing unit 3 to the display unit 4 is stopped, and the image data in the moving image buffer 2 when the storage switch is turned on The image is stored in the still image buffer through the processing unit 3 and the image is displayed on the display unit 4 as a still image. Saving of data to the video buffer 2 continues at this time, and after saving for a certain period of time so that the images before and after the storage switch is turned on are saved, the saving to the video buffer 2 is stopped. To do. In this state, any image stored in the moving image buffer 2 can be selected as a still image.
An image selected from the image data in the moving image buffer 2 is sent to the still image buffer 5 through the processing unit 3 and displayed on the display unit 4. When the selected and displayed image is a still image desired by the user or an intended still image, if the recording switch is turned on, the displayed still image is recorded in the still image memory. By associating this image with communication data such as an electronic phone book, it can be referenced from other applications such as the electronic phone book in the future.For example, if you enter a shortened number at the time of transmission, the associated still image is displayed and the other party is confirmed. Can be easily performed. If the other party is not registered in the communication data such as an electronic phone book, the name and telephone number of the other party are registered after the end of the call and the image of the other party recorded in the still image memory is electronically registered. Register in the phone book. At this time, the file number of the recorded image may be registered and associated in the electronic telephone book, and the image may be referred to and displayed from the file number at the time of display.
[0009]
In the above description, the operation by the user is described as an example in which the storage switch or the recording switch is turned on to display or record the still image. However, the switch has a two-stage operation structure, and the first half-press operation described above The recording switch operation described above may be performed by a memory switch operation or a full-press operation. In FIG. 2, an example using the two-stage operation switch will be described.
[0010]
FIG. 2 shows a display state and an operation flow.
In FIG. 2, 7 represents a moving image display state, 8 represents a still image display state, and 9 represents a moving image display state. In the moving image display state 7, the other party image during communication is displayed and updated in real time. In the still image display state 8, a still image is displayed at a certain timing in the continuous partner image. In the moving image display state 9, the still image is recorded and saved in the still image memory 6, and the other party image is displayed and updated in real time during communication.
First, in the moving image display state 7, when the switch is half-pressed, a transition is made to the still image display state 8, the still image when the switch is half-pressed is displayed on the display unit 4, and the moving image display is stopped. At this time, by tilting the switch to the left or right, it is possible to select an image that is earlier (temporally in the past) or earlier (temporally in the future) than when the switch is half-pressed.
[0011]
By further pressing the switch from the still image display state, the still image currently displayed on the display unit 4 can be recorded and saved in the still image memory or saved in the communication destination information storage area such as an electronic telephone directory. It becomes possible.
[0012]
【The invention's effect】
As described above, according to the present invention, it is possible to save a still image at an arbitrary timing from a moving image being displayed in a storage area with relatively few actions. Further, according to the image storage method of the present invention, since moving images before and after shooting are stored in the moving image buffer even if the shooting timing (storage timing) is slightly shifted, a desired still image or intended timing is selected from the moving image buffer. It is possible to easily retrieve the image. In addition, if the stored image data is associated with the number data in the electronic telephone book and the image is displayed at the time of transmission dialing, it is easy to confirm the other party.
