  The display memories (Ma) 25a, (Mb) 25b, (Mab) 25ab for the foldable display units (a) 18a, (b) 18b correspond to the screen area of the first display unit (a) 18a. A first display memory (Ma) 25a having a display data memory area; a second display memory (Mb) 25b having a display data memory area corresponding to the screen area of the second display section (b) 18b; A non-display memory (Mab) 25ab having a memory area for non-display data corresponding to the connection area Yab (see FIG. 6) between the display section (a) 18a and the second display section (b) 18b, and the folding It is configured as a memory area specified by consecutive addresses corresponding to the connecting portions between the expression display portions (a) 18a and (b) 18b and their screens.

  In this apparatus, when display data in which text and images are mixed, for example, HP (homepage) data of a website acquired by a web browser or the like is displayed by the foldable display units (a) 18a and (b) 18b. As for the image data, the image data of the portion corresponding to the connecting portion between the first display portion (a) 18a and the second display portion (b) 18b is written in the non-display memory (Mab) 25ab. It is displayed in a hidden state and displayed without a sense of incongruity that extends.

  When the data to be displayed is character data, the character data straddling corresponding to the connecting portion between the first display portion (a) 18a and the second display portion (b) 18b is Character data that is not written to the display memory (Ma) 25a and is not displayed on the first display unit (a) 18a is shifted to the second display memory (Mb) 25b side to write character information. Is displayed without unknown.

  Next, a display control function for the foldable display units (a) 18a and (b) 18b by the portable terminal 10 having the above configuration will be described.

  FIG. 5 is a flowchart showing image display processing for the foldable display units (a) 18a and (b) 18b of the portable terminal 10.

  FIG. 6 shows the state of data expansion to the display memories (Ma) 25a, (Mab) 25ab, (Mb) 25b accompanying the image display processing for the folding display units (a) 18a, (b) 18b of the portable terminal 10. FIG.

  FIG. 7 shows the data display state on the foldable display units (a) 18a and (b) 18b in the data expanded state on the display memories (Ma) 25a, (Mab) 25ab and (Mb) 25b in FIG. FIG.

  For example, when displaying the HP data of the website stored in the main memory 23 in accordance with the web browser program, the character data area and the image data area arrangement are determined from the description of HTML (Hypertext Markup Language) constituting the HP data. The entire display data corresponding to the layout is expanded and created in the main memory 23 (step S1).

  Then, for example, as shown in FIG. 6, first, the data T of the character “Aiueo ...” expanded in the main memory 23 is sequentially expanded in the first display memory (Ma) 25a line by line from the top data in accordance with the format specified by the HTML. (Steps S2 to S4).

  Here, it is determined whether or not there is character data Th protruding from the lower end of the area of the first display memory (Ma) 25a for the character data T being developed in the first display memory (Ma) 25a (step S3). If it is determined that the character data Th “Tatetsuto” exists (step S3 (Yes)), the protruding character data Th “Tatetsuto” is forcibly shifted (moved) to the second display section (b) 18b. ) And the number of moving pixels Ytb for display is recorded (step S5).

  Then, the remaining character data T after the protruding character data Th “Tatetsuto” is sequentially expanded from the upper end of the area of the second display memory (Mb) 25b in accordance with the format specified by the HTML (steps S6 to S8). .

  When it is determined that the character data T being expanded in the second display memory (Mb) 25b has character data T “Mamume Momo…” that protrudes from the lower end of the area of the second display memory (Mb) 25b. (Step S7 (Yes)), the character data T "Mamume Memo ..." is continuously developed in the range that can be developed in the second display memory (Mb) 25b (Step S9).

  Subsequently, the image data G developed in the main memory 23 (or each of the image data G1, G2,... Gn when there are a plurality of images) is developed in the first display memory (Ma) 25a according to the drawing position designated by the HTML. In this case, it is determined whether there is image data G that protrudes beyond the first display section (a) 18a (step S10).

  If it is determined that the image data G developed in the main memory 23 does not protrude when it is developed in the first display memory (Ma) 25a (step S10 (No)), It is determined whether or not the image G that does not protrude from the first display memory (Ma) 25a is for writing to the first display memory (Ma) 25a (step S11).

  Then, the image data G determined to be for writing into the first display memory (Ma) 25a is developed into the first display memory (Ma) 25a (steps S11 → S12).

  Further, the image data G determined not to be developed to the first display memory (Ma) 25a is developed to the second display memory (Mb) 25b (steps S11 to S16).

  On the other hand, in the step S10, for example, as shown in FIG. 6, it is determined that there is an image G that protrudes when the image data G developed in the main memory 23 is developed in the first display memory (Ma) 25a. (Step S10 (Yes)), first, the image data G is developed only in the image portion Ga that can be developed in the first display memory (Ma) 25a (Step S13), and the first display unit (a ) The image data Gab corresponding to the connection portion area Yab between 18a and the second display portion (b) 18b is developed in the connection portion display memory (Mab) 25ab (step S14), and the remaining image data Gb is further expanded. The second display memory (Mb) 25b is expanded (step S15).

  Thereafter, all the image data G to be displayed on the first and second display portions (a) 18a, (b) 18b developed in the main memory 23 is displayed on the display memory 25 ((Ma) 25a, (Mab). ) When it is determined that the expansion process for 25ab, (Mb) 25b) has been completed (step S17 (Yes)), the series of initial image display processes are ended.

  As described above, the character data T to be displayed protrudes from the first display memory (Ma) 25a at a character display portion where the character font is cut off at the end of the first display portion (a) 18a. The character data T after the minute character data Th is expanded from the top area of the second display memory (Mb) 25b, and the image data G to be displayed cannot be displayed on the display unit (a) 18a. As for the image data Gab + Gb that protrudes from the first display memory (Ma) 25a, the image data Gab + Gb is successively expanded to the connecting portion display memory (Mab) 25ab and the second display memory (Mb) 25b. As shown in FIG. 7, with respect to the character data T, the folding two-screen display units (a) 18a, (b) without any discontinuous or invisible characters are generated. Can be clearly displayed a lot of information in 8b, also, the image data G can display a good balance overall picture without discomfort was slow.

  Next, a scroll display control function for the foldable display units (a) 18a and (b) 18b by the portable terminal 10 having the above-described configuration will be described.

  FIG. 8 is a flowchart showing a downward scroll process associated with image display on the folding display units (a) 18a and (b) 18b of the portable terminal 10.

  FIG. 9 shows data to the display memories (Ma) 25a, (Mab) 25ab, (Mb) 25b accompanying the downward scroll processing of the image display for the folding display units (a) 18a, (b) 18b of the portable terminal 10. It is a figure which shows an unfolded state.

  In the image display function of the portable terminal 10, the movement width of the display data corresponding to one scroll can be arbitrarily set, and the set display movement amount per one scroll is Ysa.

  For example, the website HP data stored in the main memory 23 in accordance with the web browser program is stored in the folding display sections (a) 18a and (b) 18b as described in the image display processing in FIGS. When the downward scroll process in FIG. 8 is started in accordance with the operation of the down cursor key on the large keyboard 16 in the displayed state, first, the set display movement amount Ysa per one scroll is read (step A1). ).

  Then, as shown in FIG. 6, the character / image data developed and stored in the first display memory (Ma) 25a is set to the set movement amount read in step A1, as shown in FIG. Moved upward by Ysa and rewritten (step A2).

  At the same time, as shown in FIG. 6, the image data Gab + Gb that protrudes from the first display memory (Ma) 25a to the non-display memory (Mab) 25ab and the second display memory (Mb) 25b is also obtained. As shown in FIG. 9, it is moved upward by the set movement amount Ysa and rewritten (step A3).

  Further, as shown in FIG. 6, the characters / images developed in the non-display memory (Mab) 25ab and the second display memory (Mb) 25b other than the image protruding from the first display memory (Ma) 25a. As shown in FIG. 9, the data is moved upward and rewritten by the set moving amount Ysa + the connecting portion area Yab + the number of moving pixels Ytb accompanying the display protrusion (step A4).

  That is, in this state, in the image display processing in FIG. 5, the character “Tateto…” data that has been forcibly moved to the second display memory (Mb) 25b due to the protrusion from the first display memory (Ma) 25a. The original format state in which the space between the upper character data “... Sashisuseso” is reduced to the normal line space and the entire data including the image is moved upward by the set movement amount Ysa.

  Then, as shown in FIG. 6, the character / image data from the discontinuity portion of “Mamume Memo…”, for example, that is not displayed protruding from the lower end of the second display memory (Mb) 25b is described above. The set movement amount Ysa + the connecting portion area Yab + the number of moving pixels Ytb accompanying the display protrusion is additionally read from the main memory 23 and additionally developed in the second display memory (Mb) 25b as shown in FIG. (Step A5).

  Thereafter, in the state where the downward scroll instruction is continued according to the operation of the down cursor key on the large keyboard 16 (step A6 (Yes)), as shown in FIG. 9 according to the processing in the steps A1 to A5. Scrolling of the set movement amount Ysa in the state where the line spacing of the character data is restored is started, and all character / image data developed in the display memories (Ma) 25a, (Mab) 25ab, (Mb) 25b are displayed. Then, it is repeatedly moved and rewritten by the set movement amount Ysa (step A7), and the character / image data that continues below corresponding to the set movement amount Ysa is repeatedly read out from the main memory 23, and the second Additional development is performed at the lower end of the display memory (Mb) 25b (step A8).

  Thus, in the image display processing in FIG. 5, the character data is not straddled across the connecting portion between the first display portion (a) 18a and the second display portion (b) 18b as shown in FIG. In this downward scroll processing, the displayed display data is sequentially scrolled down and displayed in the same arrangement of characters and image data as the original display data, regardless of whether the character is hidden by the connecting portion. Therefore, it is possible to maintain the natural state of the display data and to realize a down scroll display without any sense of incongruity.

  After that, when the instruction to scroll down is released (step A6 (No)), at this time, the first display memory (Ma) 25a protrudes from the lower end and is spread over the non-display memory (Mab) 25ab. The length (the number of moving pixels accompanying the display protrusion) Ytb of the character on the first display memory (Ma) 25a side is calculated (step A9).

  Then, the character data that extends from the lower end of the first display memory (Ma) 25a and extends over the non-display memory (Mab) 25ab, the non-display memory (Mab) 25ab, and the second display memory (Mb) 25b Only the character / image data that has been expanded is rewritten by moving downward by the number Ytb of the moving pixel accompanying the above-mentioned connecting portion area Yab + display protruding, and connecting and protruding from the lower end of the first display portion (a) 18a. The character data hidden in the part is expanded and displayed from the upper end of the second display part (b) 18b (step A10).

  That is, in the same manner as before the down scroll processing, the character data can be clearly seen, and the original image display state is restored so that the image data can be seen without any discomfort.

  FIG. 10 is a flowchart showing an upward scroll process associated with image display on the foldable display units (a) 18a and (b) 18b of the portable terminal 10.

  For example, the website HP data stored in the main memory 23 in accordance with the web browser program is stored in the folding display sections (a) 18a and (b) 18b as described in the image display processing in FIGS. When the upward scroll process in FIG. 10 is started in accordance with the operation of the up cursor key on the large keyboard 16 in the displayed state, first, the set display movement amount Ysa per scroll is read (step B1). ).

  Then, the set display movement amount Ysa uses the character data “Tateto…” that protrudes from the lower end of the first display memory (Ma) 25a in accordance with the image display processing (see FIGS. 5 and 6) in the second display memory. (Mb) It is determined whether or not it is smaller than the amount of movement developed by moving to 25b (joint area Yab + number of moving pixels Ytb accompanying display protrusion) (step B2).

  Here, (Yab + Ytb) ≦ Ysa, that is, more than the forced movement amount (Yab + Ytb) of the protruding character from the first display memory (Ma) 25a to the second display memory (Mb) 25b in the image display process. When it is determined that the set movement amount Ysa associated with the upward scrolling process is larger (step B2 (No)), first, the difference in which the set movement amount Ysa is larger than the forced movement amount (Yab + Ytb) of the protruding character. (Ysa-Yab-Ytb) precedes characters / data developed in the non-display memory (Mab) 25ab and the second display memory (Mb) 25b other than the image protruding from the first display memory (Ma) 25a. Then, it is moved downward and rewritten (step B3).

  Subsequently, the character / image data developed in the first display memory (Ma) 25a and the image data protruding from the first display memory (Ma) 25a are moved downward by the set movement amount Ysa. It is moved and rewritten (step B6).

  That is, in this state, in the image display process in FIG. 5, the character “Tateto…” data that has been forcibly moved to the second display memory (Mb) 25b due to the protrusion from the first display memory (Ma) 25a. On the other hand, the upper character data “... Sashisuseso” is in an original format state packed to the normal line spacing, and the character / image data corresponding to the set movement amount Ysa is moved downward for the first time. .

  Then, as shown in FIG. 6, for the character / image data that has not been displayed above the upper end of the first display memory (Ma) 25a, the main memory is set by the width of the set movement amount Ysa. 23 is additionally read out and additionally developed and supplemented from the upper end of the first display memory (Ma) 25a (step B7).

  On the other hand, in step B2, (Yab + Ytb)> Ysa, that is, the amount of forced movement (Yab + Ytb) of the protruding character from the first display memory (Ma) 25a to the second display memory (Mb) 25b in the image display process. ) Is determined to be smaller than the set movement amount Ysa associated with the current upward scrolling process (step B2 (Yes)), first, the set movement amount Ysa is the forced movement amount of the protruding character (Yab + Ytb). Character / data developed in the non-display memory (Mab) 25ab and the second display memory (Mb) 25b other than the image protruding from the first display memory (Ma) 25a by a smaller difference (Yab + Ytb−Ysa). Is moved and rewritten to return upward (step B4).

  The character / data developed in the non-display memory (Mab) 25ab and the second display memory (Mb) 25b corresponds to the upward movement amount of (Yab + Ytb-Ysa) and below The character / image data following is read from the main memory 23 and additionally supplemented and developed at the lower end of the second display memory (Mb) 25b (step B5).

  Subsequently, the character / image data developed in the first display memory (Ma) 25a and the image data protruding from the first display memory (Ma) 25a are moved downward by the set movement amount Ysa. It is rewritten (step B6).

  That is, in this state, in the image display processing in FIG. 5, the character “Tateto…” that has been forcibly moved to the second display memory (Mb) 25b due to the protrusion from the first display memory (Ma) 25a. Thus, the upper character data “... Sashisuseso” is in an original format state filled up to a normal line interval, and the character / image data corresponding to the set movement amount Ysa is moved downward for the first time.

  Then, as shown in FIG. 6, for the character / image data that has not been displayed above the upper end of the first display memory (Ma) 25a, the main memory is set by the width of the set movement amount Ysa. 23 is additionally read out and additionally developed and supplemented from the upper end of the first display memory (Ma) 25a (step B7).

  As described above, the character data with the line space separated according to the connecting portion area Yab of the folding display portions (a) 18a and (b) 18b by the initial process of the upward scroll in the steps B1 to B7 is the original line interval. In the state where the character / image data corresponding to the set movement amount Ysa accompanying the upward scroll is moved downward for the first time, the upward scroll instruction is continued according to the operation of the upward cursor key. (Step B8 (Yes)), all character / image data developed in the respective display memories (Ma) 25a, (Mab) 25ab, (Mb) 25b after the first movement of the upward scroll is started are set. The moving amount Ysa is repeatedly moved downward and rewritten (step B9), and the character / image data that continues above corresponding to the set moving amount Ysa is the main. Repeatedly read additional from memory 23, it is added deployed from the upper end of the first display memory (Ma) 25a (step B10).

  Thus, in the image display processing in FIG. 5, the character data is not straddled across the connecting portion between the first display portion (a) 18a and the second display portion (b) 18b as shown in FIG. The display data displayed in this way is scrolled up and displayed in the same manner as in the original display data format, regardless of whether the character is hidden by the connecting portion. Thus, it is possible to realize an up-scroll display without a sense of incongruity while maintaining the natural state of the display data.

  Thereafter, when the upward scroll instruction is canceled (step B8 (No)), at this time, the first display memory (Ma) 25a protrudes from the lower end of the first display memory (Ma) 25a and is spread over the non-display memory (Mab) 25ab. The length of the character on the first display memory (Ma) 25a side (the number of moving pixels accompanying the display protrusion) Ytb is calculated (step B11).

  Then, the character data that extends from the lower end of the first display memory (Ma) 25a and extends over the non-display memory (Mab) 25ab, the non-display memory (Mab) 25ab, and the second display memory (Mb) 25b Only the character / image data that has been expanded is rewritten by moving downward by the number Ytb of the moving pixel accompanying the above-mentioned connecting portion area Yab + display protruding, and connecting and protruding from the lower end of the first display portion (a) 18a. The character data hidden in the part is expanded and displayed from the upper end of the second display part (b) 18b (step A10).

  That is, in the same manner as before the up scroll process, the character data can be clearly seen, and the original image display state is restored so that the image data can be seen without any discomfort.

  Therefore, according to the display control function for the foldable display units (a) 18a and (b) 18b by the portable terminal 10 having the above configuration, the first display memory (Ma) corresponding to the first display unit (a) 18a. 25a, a second display memory (Mb) 25b corresponding to the second display part (b) 18b, and a non-display memory (Mab) 25ab corresponding to the connecting part region Yab. Of the character / image data developed in the display memories (Ma) 25a, (Mab) 25ab, (Mb) 25b, the character data Th that protrudes from the lower end of the first display memory (Ma) 25a is 2 While expanding from the top of the display memory (Mb) 25b so as not to be hidden by the joint area Yab, the display memory (Mb) 25a protrudes from the lower end of the first display memory (Ma) 25a. The image data Gab straddling the reb (Mab) 25ab is continuously developed in the respective display memories (Ma) 25a and (Mab) 25ab as it is, and a part of the image data Gab is hidden in the joint area Yab. The character data T can be clearly displayed by the foldable two-screen display units (a) 18a and (b) 18b without generating uninterrupted or invisible characters. In addition, with respect to the image data G, it is possible to display the entire image in a well-balanced manner without giving a sense of discomfort that is extended.

  Further, according to the display control function for the foldable display units (a) 18a and (b) 18b by the portable terminal 10 having the above-described configuration, when performing scroll display, the lower end of the first display memory (Ma) 25a. With respect to the character data Th that is shifted to the head of the second display memory (Mb) 25b by being protruded and is expanded to avoid the joint area Yab, first, the second display memory (Mb) The character data developed in 25b is moved upward corresponding to the initial display shift amount (Yab + Ytb) and continuously developed over the first display memory (Ma) 25a to the second display memory (Mb) 25b. Alternatively, the character data developed in the first display memory (Ma) 25a is moved downward in accordance with the initial display shift amount (Yab + Ytb) of the character data less than that. Then, it is continuously expanded over the first display memory (Ma) 25a to the second display memory (Mb) 25b. As a result, the line spacing that has been evacuated by avoiding the joint area Yab is restored, and then the entire character / image data is repeatedly moved and expanded upward or downward in accordance with the scroll setting movement amount Ysa for scroll display. Thus, at the time of display scrolling, scroll display without natural discomfort can be performed by arranging the whole character / image data as set regardless of the connection area Yab.
