Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable telephone device, and more particularly to a technique for searching and displaying a telephone directory function capable of registering image information.

[0002]

2. Description of the Related Art A conventional portable telephone device has a name,
It has a telephone directory function in which a plurality of telephone numbers and other personal information attached thereto are registered in association with each other (registration data), and a series of information can be quickly read out if necessary. With this telephone directory function, it becomes possible to make a telephone call without looking at other media such as a paper telephone directory or an address book. In addition, this phonebook function can compare and retrieve the called number notified by the other party based on the registration data of the portable telephone device when a call is received, and display the corresponding name information. This allows the user to know who is calling before answering the call.

As an example of a portable telephone device, a portable video telephone device which can handle image information, in particular, can transmit and receive voice and image at the same time so that the user can talk while seeing the image sent from the other party. . This portable videophone device can store the received image during the call as it is, or can store the image captured by the camera built in the portable videophone device as it is.

In the portable videophone device capable of storing image information as described above, the stored image data can be treated as ancillary information of the registration data of the telephone directory. With this, when searching for personal information using the telephone directory, it becomes possible to search by looking at the image information, and at the time of an incoming call, by displaying the image information corresponding to the called number together with the name information, It is possible to understand the calling party more intuitively.

Usually, the image data has a larger amount of data than the character information. Therefore, in a portable videophone device capable of handling the image information, the captured image is JPEG (Join).
Photographic Expert Group), etc., to reduce the amount of data in the image and enable more images to be stored.

On the other hand, as a method for retrieving necessary information using this telephone directory, a method for directly retrieving information by inputting information (name or address) related to a calling party, or
There is a method of searching while checking registered data one by one. In any case, when the retrieved information does not correspond to the purpose, the retrieval is sequentially performed until the desired information can be extracted. For example, a key for opening the phone book is pressed to enter the phone book mode, and a part of the name of the person to be searched is input to execute the search process. The closest information among the registered data is displayed as the search result. Generally, registered data is sorted based on information such as name, so if the displayed search results do not meet your purpose, press the up and down scroll keys to move the information before and after the displayed information. Since the registered data that is located is sequentially displayed, the user can search for the data corresponding to the purpose while observing the displayed contents.

[0007]

However, in the telephone directory of the portable videophone device, it is necessary to display and output the attached image data in addition to the character information such as the name and telephone number, so that the telephone directory is registered. Unlike the portable telephone device in which the data is only the character information, the image information could not be immediately displayed and output in response to the search operation of displaying the registration data in order.

The cause of this is that, as described above, the data amount of image data is larger than that of character information.
The amount of data is reduced and stored by performing encoding processing such as. Therefore, when displaying and outputting, it is necessary to perform decoding processing and output, and it takes time required for decoding / displaying image information in addition to the time required for displaying character information.

The load associated with this decoding process may appear as a load on the operability, for example, "the key does not move to the next search even if a key operation is performed until the image of the search once determined is displayed." is there. This becomes a problem in that a light operability cannot be obtained particularly when sequentially searching in a sort order based on name information or the like.

On the other hand, in response to a key press, only the data such as character / symbol information, which is the registered data of the telephone directory, which is not a key operation load is displayed first, and the data such as image information which is a key operation load is displayed. With regard to the above, by starting and displaying the image display processing (decoding / display) after an arbitrary time has elapsed after pressing the key, operability that is easy for the user to use for continuous search is secured.

In addition, the procedure of scrolling the registered data of the telephone book one after another by pressing the operation key for a long time is such that the CPU recognizes that the scrolling display is made after a certain time has elapsed since the operation key was first pressed, and the registered data is displayed one after another. It will be displayed. To stop scrolling, release the release of the operation key to stop.

In this case, the image decoding process starts after the operation key is first depressed. Then, if the predetermined time until the scroll display is shifted is shorter than the decoding processing time, processing such as stopping the image decoding process occurs when the scroll display is shifted. Since this stop processing overlaps with the scroll display control, there arises a problem that the display of the character information immediately after the shift to the scroll display is slightly shifted (see FIG. 5).

Referring to FIG. The figure shows a process in the case of decoding an image after a fixed time based on a press signal (including long press and repeat). First press (1)
The character information corresponding to the search A is displayed corresponding to, and the image decoding process is started at the same time when the timer until the image decoding is started and expires. However, a long press (2) signal is output from the operation unit which is kept pressed, and the image decoding process is requested to be stopped. However, at this time, the display of the character information corresponding to the search B is slightly delayed due to the load of the decoding stop processing. After that, a repeat signal for displaying the next is input from the operation unit that is kept pressed, the timer is stopped / started each time, and corresponding character information is displayed.
As a result, the character information display output state becomes shorter than the display time of the search C and the search D that are followed by the display of the search B at the time of transition to the scroll search.

In order to prevent this, it is conceivable to display the character information of the search B before the image decoding stop processing. For example, after the long push (2) signal is output from the operation unit (scroll display start). ), When the operator depresses the operation unit and immediately depresses the operation unit again, when the character information corresponding to the depression from the new operation unit is displayed, the process of stopping the previous image decoding process is performed. As a result, the display will be delayed, and this will not solve the problem.

[0015]

In order to solve the above problems, a portable telephone device according to claim 1 stores character information such as a name and a telephone number, and image information corresponding to the character information, and stores the character information. a portable telephone apparatus having a telephone directory function for searching the storage contents, an operation unit, of the operating means

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. Note that the same reference numerals are used for the portions having the same configuration. FIG. 1 is a basic configuration diagram of a telephone directory process of a portable videophone device according to an embodiment of the present invention. In FIG. 1, 1 is a phonebook sort information section, 2 is an operation input section, 3 is a control processing section, 4 is a phonebook character information storage section, 5 is a display data processing section, 6 is a character information display output section,
Reference numeral 7 is a display output unit, 8 is a telephone directory image information storage unit, 9 is an image decoding processing unit, and 10 is an image information display output unit.

Next, the operation will be described. In response to the search request from the operation input unit 2, the control processing unit 3 searches the registered data based on the information in the telephone directory sort information unit 1. When the search request from the operation input unit 2 is a push-down, long-press, or repeat signal, information that can be displayed immediately, such as character information, is read from the telephone directory character information storage unit 4 and processed by the display data processing unit 5. It is processed and displayed on the character information display output unit 6 of the display output unit 7. When the search request from the operation input unit 2 is a release signal, a delay timer for starting image decoding is started, and when the delay timer expires, the image information is read from the telephone directory image information storage unit 8 and the image decoding processing unit is read. Decoding processing is performed at 11, and the image information is displayed and output to the image information display output unit 13.

FIG. 2 is a flow chart showing a telephone directory processing procedure at the time of starting a search in the portable videophone apparatus according to the embodiment of the present invention. In FIG. 2, when the operator inputs a search operation (press, long press, repeat), the character information of the search result is displayed and output (S101).
At that time, if the image information is in the decoding process (S102) and the display request image (hereinafter, the requested image) as a result of the search and the decoding image do not match (S103), the process in the decoding process is stopped (S104). ). If the image being displayed at this time is different from the requested image, the display is once blackened (S10).
5 to S107). Then, the requested image is registered as a reserved image (image to be decoded and displayed next) (S108). Even when the decoding process is not in progress (S102), if the image being displayed is different from the requested image, the display is once blackened and the requested image is registered as a reserved image (S110 to S113).
If the decoding start delay timer is operating, the timer is stopped.

FIG. 3 is a flow chart showing a telephone directory processing procedure at the end of the search in the portable videophone apparatus according to the embodiment of the present invention. In FIG. 3, when a release signal indicating that the continuous search operation by the operator is stopped (for example, when the pressed operation button or lever is released) is detected, it is first determined whether or not there is a reserved image to be decoded (S201). Here, it is checked whether image information corresponding to the search result is registered as a reserved image. Next, if there is a reserved image, it is judged whether or not this reserved image and the currently displayed image match (S202), and a delay for starting decoding of the reserved image when the reserved image and the currently displayed image do not match. The timer is started (S203). After that, when there is no interrupt signal from the operation unit and the timer expires (S204), decoding of the reserved image is started (S205), and the image information is displayed after the decoding is completed.

FIG. 4 is a diagram for explaining the operation at the time of searching the telephone directory of the portable videophone device according to the embodiment of the present invention. In FIG. 4, from the top of the figure, the timing of inputting a signal associated with the search operation, the search result, the display output state of the character information, the state of starting / operating / stopping the timer, the start / stop / end / end of the decoding process And a display output state of image information. The up and down arrow lines indicate interlocking processing. The capital letters represent the identification of the registration data in the search results, and the same capital letters represent the same registration data.

In FIG. 4, when the user starts searching the telephone directory, first, the character information of the search result A associated with the first operation (press (1)) is displayed, and black (invalid image) is displayed as an image. . Next, when the user continues to hold down the operation unit to perform continuous search, the CPU keeps pressing (2)
To detect. Then, after that, the repeat signal is output at a constant interval as long as the operation unit is held down. Further, the display of the search result corresponding to the long press (2) and the repeat signal only updates the character information. After that, when the user releases the operation unit that has been held in order to stop the continuous search, a release signal is output and a timer for starting image decoding is started. Then, when the timer expires, image decoding / display processing is started, and the image is displayed upon completion of decoding.
As a result, a comfortable operability can be secured by eliminating the load of image decoding during scroll search.

[0023]

As described above, as in the portable telephone device of the present invention, the structure for initiating the image decoding / display processing based on the release signal of the operation key causes the scroll search of the telephone directory ( It is possible to exclude the decoding process and the stopping process for useless images that become an operation load in (display) and execute the decoding process of the image information only for the information selected by the user. The processing does not operate in parallel, the processing speed can be stabilized, and the operability can be ensured.

In addition, by allowing a predetermined time from the output of the release signal to the image decoding by the timer, it is possible to immediately respond to the re-input of the search from the user.
