DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable terminal capable of inputting and outputting data by connecting to another information processing apparatus, and more particularly, to a method for displaying data input from another information processing apparatus on the portable terminal.

[0002]

2. Description of the Related Art Computers have been reduced in size, and small and portable computers have become widespread. Because portable computers are designed to be portable, they are smaller than desktop computers. The portable computer has a small keyboard or tablet for data input and a liquid crystal display for data display. FIG. 1 shows an example of a schematic view of a general portable computer. The example of FIG. 1 is an example including a small keyboard and a liquid crystal display on which tablets are superimposed. Portable computers can electronically manage data such as schedules and phonebooks,
In addition, since it is a portable size, data can be referred to at a destination. Hereinafter, a portable computer is referred to as a “mobile terminal”. In a mobile terminal equipped with a tablet as in the example of FIG. 1, the operator can execute the function by directly pointing an icon displayed on the liquid crystal screen with an attached pen or finger. Some mobile terminals can take a handwritten memo using a tablet. FIG. 2 is a diagram illustrating a screen example of a handwritten memo. As shown in the figure, when the operator drags the liquid crystal screen with the pen, the locus of the pen is displayed on the liquid crystal screen as if the user traced the paper with a pencil. The handwritten memo is stored as image data in a storage unit in the portable terminal, and can be read and used when needed by the operator.

On the other hand, some portable terminals are provided with connection means such as an RS-232C (registered trademark) serial connection and an infrared connection for exchanging data with another computer. By the connection means, data can be input / output between the computer and the portable terminal which are usually used. FIG. 1 shows an example in which an RS-232C serial connection is provided.
Mobile terminals with connection means are easy to carry,
Because it is easy to exchange data with the desktop computer, you can import data from the desktop computer to your mobile device,
The ability to display data captured on the go is frequently used.

[0004]

However, the desktop computer and the portable terminal may have different data formats or different operating systems. Even if the data of the desktop computer is transferred to the portable terminal. In some cases, the program on the mobile terminal side cannot handle data.

In order to solve this problem, data compatibility is established in the data format of image data, data of a desktop computer is converted into image data, and the data is transferred to a portable terminal as image data. That is, the information of the desktop computer is displayed on the screen of the desktop computer, and a hard copy of the screen is stored as image data. Then, if the image data is transferred to the portable terminal, the screen data of the desktop computer can be referred to on the portable terminal, and almost the same information is transferred. Thereby, the information on the screen of the desktop computer can be referred to by the portable terminal.

However, each of the transferred image data is transferred as one file, and is stored separately in the portable terminal. Therefore, when the operator attempts to refer to the transferred image data, the contents of the image data must be guessed from the file name, and it takes time and effort to search for the desired image data. in this way,
Import image data from a desktop computer to a mobile device,
An object of the present invention is to reduce the work that has occurred when an operator refers to data.

[0007]

According to the present invention, a storage means for storing one or more pieces of image data, an image processing means capable of newly creating and editing image data in the storage means, Display means for displaying the image data by the processing means, transfer means for transferring the image data of the external information processing device to the storage means, and whether the image data of the storage means is image data created by the image processing means A determination unit that determines whether the image data is image data transferred from an external information processing apparatus, and outputs a determination result. The image processing unit refers to the determination result of the determination unit, and stores a handwritten memo in the storage unit. If there is image data other than the data, it is converted into a form that can be handled by a handwritten memo pad program, handled in the same way as a handwritten memo, and can be displayed / edited.

Thus, the operator does not need to handle the input handwritten data and the image data transferred from the desktop computer separately, and can refer to the same operation.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described.
This will be described with reference to the drawings.

It is a means for connecting to a desktop computer.

In a portable terminal equipped with a tablet as shown in FIG. 1, an operator can directly execute an icon displayed on a liquid crystal screen by using an attached pen or finger to execute the function. . Specifically, when the operator first designates an icon on the liquid crystal screen, the tablet detects the designated coordinates. The procedure is to execute the function of the icon when the designated coordinates match the coordinates of the icon displayed on the liquid crystal.

Further, according to the present invention, a handwritten memo can be taken using a tablet of a portable terminal. As shown in FIG. 2, when the operator drags the liquid crystal screen with a pen,
The trajectory of the pen is displayed on the LCD screen as if it were traced on a piece of paper with a pencil. Specifically, when the operator first drags the liquid crystal screen, the tablet detects the dragged coordinates. In this procedure, the locus is displayed on the liquid crystal screen by displaying the liquid crystal pixels at the designated coordinates in a color different from the background color.

FIG. 2 is a view showing the "edit screen" immediately after the start of the handwritten notepad program. 201 is a “memo display area” for editing or displaying a handwritten memo, 202 is
A "new button" for activating a function for newly creating a memo, a "delete button" 203 for activating a function for deleting one memo, and a 204 for activating a function for displaying a page before the memo. A “previous page button” 205 is a “next page button” that activates a function of displaying the next page of the memo,
Reference numeral 06 denotes a “list button” for activating a function for displaying a list of memos, and reference numeral 207 denotes an “end button” for ending the handwritten memo pad program. The operator has the "New Button"
, One blank memo is created, and the memo is entered by directly pointing the memo display area 201 with a pen. When the user wants to see the previous memo, he designates the “previous page button”, and when he wants to see the next memo, he designates the “next page button”. When the "list button" is instructed, the handwritten memo is reduced and displayed in a list as shown in FIG.

FIG. 3 shows a "list screen" displayed in response to a "list button" instruction. Reference numeral 301 denotes a memo pad in which the “memo display area” is reduced to あ た り per side. Since four images are displayed in a list on one screen, the outline of the memo can be grasped on this screen. Reference numeral 302 denotes a “previous page button”, which displays the previous four pages in the memo sequence. Reference numeral 303 denotes a “next page button”, which displays the next four pages in the memo sequence.

Reference numeral 304 denotes a “date display” displaying the date when the memo was created. The date display indicates the date when the memo was created. The handwritten memo file is
One memo is stored in the data storage area 503 and one memo is stored.
Saved as two files. The file name is a number in which 11 digits are arranged in the created date, including 4 digits for the Christian era, 2 digits for the month, 2 digits for the day, and 3 digits for the serial number. For example, for the first memo created on December 11, 1997, the file name of the memo is "19971211001". The serial number is increased by one when a plurality of memos are created on the same date.

If there is a file represented by an 11-digit number, it is determined that the file is data of a handwritten memo, and as shown in FIG. 3, 4 digits, space, 2 digits, space, 2 digits, space, 3 Separate digits and numbers for easy viewing. If there is a file that is not represented by an 11-digit number, the file is determined to be data other than the data of the handwritten memo (that is, data transferred from the desktop computer), and the file name is entered without spaces. It is displayed as it is (in FIG. 3, "MapOfTown" at the lower right is an example). If the handwritten memo data created by the handwritten memo program and the data transferred from the desktop computer have different data formats, data conversion is performed.

In this embodiment, the data of the handwritten memo is distinguished by using the file name, but the management information may be recorded as another file. Further, whether or not the date is displayed on the list screen and where to display the date may be set by the operator on a user setting screen as shown in FIG.

If the image does not look small or needs to be edited on the reduced screen, the operator can select a desired memo from this screen and move to the screen shown in FIG. When a memo is instructed using a pen on the “list screen”, the selected memo is displayed in reverse video as indicated by 305.
In this state, when the “selection button” 306 is selected, one memo, which has been highlighted, is displayed as shown in FIG.

The handwritten memo is converted into image data as
It is stored in a storage means in the portable terminal, and can be read and used when needed by the operator.
