ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a display controller for a communication apparatus and its method, and, more particularly, to a display controller for a communication apparatus for displaying a received message, and its method.
2. Description of the Related Art
A conventional communication apparatus, for example, a pager with a display function, receives a message signal contained in a radio signal, and displays a received message on a display section. When one entire received message cannot be displayed on the display section at once, the message is first displayed in the maximum number of characters that can be displayed on the display section. Then, the message portions to be displayed are sequentially changed by the user for operating a scroll button or the like.
However, when the conventional pager with a display function receives a message with number of characters exceeding the number of characters which can be displayed on the display section at once, the user should operate the scroll button time and again. Therefore, when information is provided for a user by receiving and displaying a large amount of information, for example, data from a personal computer or the like, there is a problem that it is inconvenient and cumbersome for the user to view all information.
In addition, since the conventional pager with the display function displays all characters in double-width, more limitation than necessary is imposed on the number of characters displayed on the display section.
On the other hand, Japanese Patent Application Laid-Open No. 6-77881 discloses a radio selective calling receiver in which, display is performed by using characters with a size of 2N*2M dots if the number of characters of a received message exceeds a predetermined number, and by using characters with a size of N*M dots if the number of characters of the received message is equal to or larger than the predetermined number.
However, since the receiver in the laid-open application changes the size of character to be displayed depending on the number of received characters, it can use only characters the size of which can be changed.
SUMMARY OF THE INVENTION
An object of the present invention is to solve the above problems, and to provide an improved display controller for a communication apparatus and its method.
Another object of the present invention is to provide a display controller for a communication apparatus and its method, wherein the number of characters displayed on a display section can be increased to display more messages.
Still another object of the present invention is to provide a display controller for a communication apparatus and its method, wherein, when a message in the number of characters which is larger than that displayed on a display section at once is received, a part of the message is displayed in singe-width characters.
In addition, the present invention is intended to provide a display controller for a communication apparatus and its method, wherein it enables it to improve operability when one entire message is viewed.
Furthermore, the present invention is intended to provide a display controller for a communication apparatus and its method, wherein it enables it to change character size depending on the type of character in a message.
To attain the objects described above, the present invention is a display controller for a communication apparatus receiving signals containing a message and displaying the received message on a display section, the display controller comprising first storage means for storing the maximum number of characters in a message which can be displayed on the display section, determination means for comparing the number of characters in the received message with the maximum number of characters, and, if the number of characters in the received message is larger than the maximum number of characters, determining whether or not the received message contains characters of a predetermined specific type, converter means for converting the size of character of the predetermined specific type into a smaller size if characters of the specific type are contained on the basis of determination by the determination means, and control means for displaying the received message in at least two different sizes on the display section.
The control means is preferable to display characters of those constituting the received message which are of other than the predetermined specific type on the display section in the double-width size, and characters of the predetermined specific type in the single-width size.
In addition, it is preferable to further comprise second storage means for storing the received message in the at least two sizes.
Furthermore, the display controller is desirable to comprise second storage means for storing the received message in the same size, and operation means for instructing display of the message stored in the second storage means on the display section, wherein the determination means compares the number of characters in the stored message with the maximum number of characters, and, if the number of characters in the stored message is larger than the maximum number of characters, determines whether or not the stored message contains characters of a predetermined specific type, the converter means converting the size of character of the predetermined specific type into a smaller size if characters of the specific type are contained, the control means displaying the stored message in at least two different sizes on the display section.
Furthermore, the display controller for a communication apparatus according to the present invention comprises receiver means for receiving a message, display means for displaying the message received by the receiver means, and control means for compressing and displaying the received message on the display section if the amount of the received message is larger than a display capacity of the display means.
The control means is preferable to compress and display double-width characters in the received message into single-width characters.
Furthermore, a display control method for a communication apparatus according to the present invention is a display control method for a communication apparatus receiving signals containing a message and displaying the received message on a display section, the display control method comprising the steps of storing the maximum number of characters in a message which can be displayed on the display section; comparing the number of characters in the received message with the maximum number of characters; if the number of characters in the received message is larger than the maximum number of characters, determining whether or not the received message contains characters of a predetermined specific type; converting the size of character of the predetermined specific type into a smaller size if characters of the specific type are contained; and displaying the received message in at least two different sizes on the display section.
The displaying step is preferable to display characters of those constituting the received message which are of other than the predetermined specific type on the display section in the double-width size, and characters of the predetermined specific type in the single-width size.
