Description

  The present invention relates to a user interface technique in an image information processing system.

Some apparatuses that process image information display an image on a storage-type display medium. Here, a storage-type display medium is a medium that maintains display contents even when power supply is interrupted. Among such display media, a particularly thin one is sometimes called electronic paper. There are a liquid crystal system, an electronic powder fluid system, a microcapsule system, and the like as a memory-type display medium. However, since the rewriting speed is generally slow, various techniques for improving the rewriting speed have been developed. For example, in Patent Document 1, an update area in which at least a part of an image on the display is updated is determined based on the currently displayed image and the changed image, and the display is displayed only for the determined area. A technique for improving the rewriting speed by rewriting is described.

(B-1: Connection operation)
FIG. 6 is a sequence diagram for explaining the operation when the display medium 10 and the controller 20 are connected. When the user sandwiches the controller 20 in the display medium 10, the CPU 21 of the controller 20 detects that the terminals are connected (step SA001), and supplies power to the display medium 10 (step SA002). Then, the CPU 21 reads out the icon data from the icon database 241 and the icon correspondence table 242 in the storage unit 24 and the identifiers of the scanning line driving circuit 11 and the data line driving circuit 12 assigned thereto (step SA003). These pieces of information are transmitted to the display medium 10 (step SA004). The display medium 10 having received these pieces of information from the controller 20 stores each icon data in the icon memory 122 of the data line driving circuit 12 assigned thereto for each identifier of the scanning line driving circuit 11 (step SA005). ). Here, the contents stored in the icon memory 122 are written once at the time of connection described above, and are held while power is supplied from the controller 20.

(B-2: Instruction content specific operation)
FIG. 7 is a sequence diagram for explaining the operation of specifying the instruction content based on the position instructed by the user. When the user presses the transparent touch panel that is the position detection unit 15 of the display medium 10 with a predetermined pen tip or the like, the position detection unit 15 detects the pressed position (step SA101) and is instructed in the display area 13. The position information indicating the detected position is transmitted to the controller 20 (step SA102). When receiving the position information (operation signal), the CPU 21 of the controller 20 specifies the instruction content based on the position information (step SA103), and executes processing according to the specified instruction content (step SA104). For example, when an operation icon is displayed at a position indicated by the position information by an operation icon display described later, first, icon data of the operation icon indicated by the position indicated by the position information is specified, and the icon correspondence table 242 is specified. , The subroutine name corresponding to the displayed operation icon is specified, and the subroutine having this subroutine name is executed. In the process of opening the file, if the file name or page number of the file stored in the storage unit 24 of the controller 20 is described at the position indicated by the position information, the CPU 21 A file name is specified, content data corresponding to the file name is read with reference to the content database 243 in the storage unit 24, and image information that is raster image data is generated by the GPU 23 based on the read content data. In order for the CPU 21 to specify the instruction contents based on the position information, the contents of the operation icon display or content display performed immediately before are stored in the RAM of the CPU 21 or the VRAM 231 of the GPU 23, and these may be referred to.

FIG. 8 is a sequence diagram illustrating an operation when the display medium 10 displays content. The CPU 21 of the controller 20 specifies an image to be displayed on the display medium 10 as a result of specifying the instruction content described above (step SA201). For example, if the specified instruction content is to display content data associated with a page number with a certain file name as a result of specifying the instruction content, the CPU 21 displays the content data with this file name / page number. Read from the content database 243 of the storage unit 24, and the GPU 23 generates image information based on the content data (step SA202). Then, the panel controller 22 of the controller 20 transmits the image information generated by the GPU 23 to the display medium 10 (step SA203). When the display medium 10 receives the image information from the controller 20, the display medium 10 divides the image information for each corresponding data line drive circuit 12, and stores each of the image information in the line memory 121 of the data line drive circuit 12 (step SA204). 20 is notified that the storage is complete (step SA205). Upon receiving this notification, the controller 20 generates a synchronization signal by the panel controller 22 based on the clock output from the CPU 21 (step SA206) and transmits it (step SA207). Upon receiving this synchronization signal, the display medium 10 synchronizes the scanning line driving circuit 11 and the data line driving circuit 12 (step SA208). Each data line driving circuit 12 reads the image information divided from the line memory 121 in synchronization with the scanning of each scanning line by the scanning line driving circuit 11 (step SA209), and supplies this image information to the data lines. To do. As a result, the content is displayed in the display area 13 (step SA210).

The predetermined condition may be immediately after the display medium 10 and the controller 20 are connected, and the position detection unit 15 of the display medium 10 may be set by the user. The designated position is detected and the designated position information indicating the designated position is sent to the controller 20. The designated position information received by the CPU 21 is compared with the range information stored in the storage unit 24 in advance, and the designated position information indicates The predetermined condition may be that the indicated position is within a predetermined range indicated by the range information. Further, the predetermined condition may be both of them.

  First, the controller 20 generates a synchronization signal by the panel controller 22 based on the clock output from the CPU 21 (step SA301), adds a predetermined pulse signal thereto (step SA302), and transmits it (step SA303). . When the display medium 10 receives this synchronization signal and the added pulse signal (hereinafter referred to as an additional pulse), it synchronizes the scanning line driving circuit 11 and the data line driving circuit 12 (step SA304). The additional pulse is supplied to each of the four data line driving circuits 12, and each data line driving circuit 12 reads icon data from the icon memory 122 in response to the additional pulse (step SA305), and the scanning line driving circuit 11 The icon data is supplied to the data line in synchronization with the scanning of each scanning line. As a result, an operation icon corresponding to the additional pulse is displayed in the display area 13 (step SA306).

In FIG. 10A, the vertical axis indicates the signal value, and the horizontal axis indicates time t. The signal value is either a high level (denoted as H in the figure) or a low level (denoted as L in the figure). The synchronization signal is recognized by the display medium 10 when the signal value has been at a high level for a predetermined time, and after the synchronization signal, at the moment when the signal value has become a low level, the scanning line driving circuit 11 and the data are detected. The line drive circuit 12 is synchronized. This synchronized timing is defined as an origin O, and an ON period for receiving an additional pulse from the origin O over a predetermined time is determined. The ON period is divided into a first ON period, a second ON period, a third ON period, and a fourth ON period in order as time passes. The first ON period corresponds to the data line driving circuit 12a, the second ON period corresponds to the data line driving circuit 12b, the third ON period corresponds to the data line driving circuit 12c, and the fourth ON period corresponds to the data line driving circuit 12d. doing. Each data line driving circuit 12 reads icon data stored in association with its own identifier from the icon memory 122 in the ON period corresponding to itself, and drives the data line according to the read icon data. For example, in the example of FIG. 10, since all ON periods corresponding to the data line driving circuits 12 a to 12 d exist, operation icons are read from the icon memories 122 of all the data line driving circuits 12 and are displayed in the display area 13. Is displayed.
On the other hand, FIG. 11 is a diagram illustrating a case where some operation icons are displayed by the additional pulse. The additional pulse shown in FIG. 11A has a high signal value only during the first ON period and the fourth ON period. Therefore, only the data line driving circuits 12a and 12d are driven, and as a result, only the operation icons I1 to I6 corresponding to the data line driving circuits 12a and 12d are read and displayed in the display area 13.

  Here, partial rewriting when an operation icon is drawn superimposed on image information of content will be described. FIG. 12 is a schematic diagram for explaining this partial rewriting. On the right side of FIG. 12, pixels of 2 rows and 2 columns in the upper left of the operation icon I1 are shown. On the left side of FIG. 12, the destination where these pixels are displayed in the display area 13 of the display medium 10 is shown. Thus, in the display area 13, every four pixels of the operation icon are assigned in the vertical and horizontal directions. Therefore, when the operation icon is displayed, the scanning lines of the scanning line driving circuit 11 are scanned every four lines (in the example shown, the scanning lines SL1, SL5,...). That is, when scanning is advanced from one scanning line to the next, scanning is performed by skipping three consecutive scanning lines. The data line driving circuit 12 also drives only every fourth data line (in the example shown, data lines DL1, DL5...), And outputs image information to the pixels. That is, the scanning line driving circuit 11 drives only a part of the scanning lines SL in the scanning line group corresponding to its own means, and the data line driving circuit 12 is a part of the data line group corresponding to its own means. Only the data line DL is driven according to the icon data. Accordingly, the pixels provided on at least one of the scanning line and the data line that are not driven maintain the previous state, and thus the display medium 10 can be partially rewritten. Here, every four scanning lines and data lines are driven, but this number is not limited to four, and such partial rewriting can be performed if it is an integer of 2 or more. The number of lines that are not driven need not be the same between the scanning lines and the data lines. For example, every two scanning lines may be driven and every three data lines may be driven.

  FIG. 13 is a diagram for explaining a state in which the operation icon is drawn superimposed on the image information of the content. As described above, when the operation icon is drawn, the display medium 10 performs partial rewriting by driving the scanning lines and the data lines every predetermined number of lines. In addition, since each pixel of the operation icon is drawn in a distributed manner, the operation icon is drawn superimposed on the content image.

  With the above configuration, the content and the operation icon are drawn in the display area 13 of the display medium 10 according to different procedures. Thereby, first, icon data for drawing an operation icon is sent to the display medium 10 only once when connected to the controller 20, and is stored in the icon memory 122 during this connection period. Therefore, since the display medium 10 does not need to receive icon data from the controller 20 every time an operation icon is drawn, the operation icon can be drawn at high speed. Secondly, since the icon data is raster image data, it can be directly supplied to the display medium 10 without performing predetermined processing by the GPU 23 in the controller 20. Therefore, the processing time in the GPU 23 and the time spent for exchanging information with the GPU 23 can be shortened, so that operation icons can be drawn at high speed. Third, since each icon data is associated in advance with a unique set of the scanning line driving circuit 11 and the data line driving circuit 12, it is not necessary to calculate the position where the operation icon is drawn. Therefore, the operation icon can be drawn at high speed. Fourth, when the operation icon is drawn, the display medium 10 drives the scanning lines and the data lines every predetermined number, so that when the operation icon is drawn in the same range, all of the display icons passing through the range are displayed. Compared to driving scanning lines and data lines, operation icons can be drawn at a higher speed, and the image originally drawn in the drawing range remains partially. The content at the specified position can be inferred.

  Further, the display medium 10 and the controller 20 of the image information processing system 1 are configured to be detachable. Therefore, the user can remove the controller 20 so that the weight is not applied to the display medium 10. Even if the controller 20 is removed, the display content of the display medium 10 is maintained. For example, if the display content is simply read, the user need only handle the display medium 10. Therefore, user convenience can be improved.

(C: Modification)
The above-described embodiment may be modified as follows.
(1) In the above-described embodiment, the same operation icon is displayed regardless of the owner of the display medium 10, the specific conditions of the display medium 10 itself, or the content displayed on the display medium 10. Although processing has been performed, the operation icon to be displayed changes depending on the identification information associated with the display medium 10 or the identification information of the image displayed on the display medium 10, or a process that can be executed by the operation icon May change. In this case, the display medium 10 includes identification information associated with the display medium 10 such as an identifier of the owner of the display medium 10 and a manufacturing number of the display medium 10, and identification of the last image displayed on the display medium 10. A storage unit (identification information storage unit) that stores information (a combination of a file name and a page number) is provided, and the display medium 10 and the controller 20 (identification information transmission unit) are connected to supply power to the display medium 10. These may be transmitted to the controller 20 immediately after being performed, that is, after the above-described step SA002. The storage unit 24 of the controller 20 stores an icon correspondence table 242. The icon correspondence table 242 further includes an identifier of the owner of the display medium 10, a manufacturing number of the display medium 10, and a file name. The CPU 21 compares the owner identifier and the serial number received from the display medium 10 with the owner identifier and serial number described in this field. If they do not match, some limitation may be made, for example, by changing the additional pulse transmitted by the panel controller 22 so that the operation icon is not displayed on the display medium 10. As a result, for example, if the owner is not authorized in advance, it is possible to limit the processing according to the content of each user or content, such as preventing the display content from being copied, thus improving security. be able to. Note that the timing at which the display medium 10 transmits the above-described identification information to the controller 20 is not limited to after the above-described step SA002, and may be performed at various timings. For example, the position detection unit 15 of the display medium 10 may transmit the position information of the detected position to the controller 20 at a timing. Further, the identification information stored and transmitted by the display medium 10 is not limited to the owner's identifier, the manufacturing number of the display medium 10, and the file name / page number pair, and other various identification information is stored and transmitted. Alternatively, only a part of these may be stored and transmitted.

(2) In the above-described embodiment, the controller 20 does not have an operation unit that receives a user operation and outputs an operation signal according to the operation, and the CPU 21 detects that the terminals are connected to each other. The operation icon is transmitted to the display medium 10 by the above-mentioned, but the controller 20 is provided with an operation unit that receives a user operation and outputs a signal according to the operation content. You may perform the process of.
In the above-described embodiment, the controller 20 is not provided with an image display unit that displays an image. However, the controller 20 may be provided with an image display unit that is separate from the display medium 10.

FIG. 14 is a diagram for explaining a mode in which an operation unit and a display device are provided in the controller 20. As described above, the controller 20 includes the operation unit 26 as an operation unit that receives a user's operation and the display unit 27 as a display device that displays an image. The operation unit 26 includes a transparent touch panel 261 and a button 262, which are assigned predetermined functions. The display unit 27 is a liquid crystal display, on which icons 271, 272, and 273 are drawn. A transparent touch panel 261 is provided over the liquid crystal display. When the transparent touch panel 261 is pressed by the pen tip or the like by the user, the coordinate information corresponding to the position is output to the CPU 21. CPU21 compares this coordinate information with the display content of the display part 27, and specifies instruction | indication content. Note that the display content of the display unit 27 may be stored in the RAM of the CPU 21 or may be stored in the VRAM 231 of the GPU 23. When the button 262 is pressed by the user, the button 262 outputs a signal, and when this signal is received by the CPU 21, the processing in steps SA 003 to SA 005 described above, that is, stored in the icon database 241 is triggered by this. A process of storing the icon data thus performed in the plurality of icon memories 122 of the display medium 10 is performed. Note that the operation icon display process may be performed instead of the process of storing the icon data in the icon memory 122 when the button is pressed.

(3) In the above-described embodiment, the display medium 10 is not provided with a control device such as a CPU, and the additional pulse is displayed by being supplied to each of the four data line driving circuits 12. An operation icon has been identified. However, the display medium 10 may be provided with a control device such as a CPU to analyze the additional pulse.

  In the above-described embodiment, each ON period represented by the additional pulse corresponds only to each data line driving circuit 12, but may correspond to each scanning line driving circuit 11. Further, it may correspond to a set of each scanning line driving circuit 11 and each data line driving circuit 12. That is, the panel controller 22 of the controller 20 may supply a set of identifiers of each scanning line driving circuit 11 and each data line driving circuit 12 to the display medium 10 by an additional pulse.

(4) In the above-described embodiment, only one display medium 10 is sandwiched between the controllers 20, but it may be two or more. In this case, for example, the power receiving terminal 141 and the data terminal 142 provided on the display medium 10 may be configured to conduct from the back surface to the front surface. Further, an identifier is stored in each of the two or more display media 10, and in addition to the position instructed by the position detection unit 15, the identifier of the display medium 10 is transmitted, so that the display medium on the most front side is displayed. 10 may be specified. In this way, the processing contents can be changed between the display medium 10 on the most front side and the other display mediums. For example, the contents displayed on the display medium 10 on the most front side can be changed to other display media. 10 can be easily copied.

(5) In the above-described embodiment, the resistive film type transparent touch panel provided over the display area 13 is used as an example of the position detection unit. However, the transparent touch panel of another type (matrix switch type or the like) is used. There may be. Further, the position detection means is not limited to the touch panel. For example, a camera may be incorporated in a pen tip where the user indicates somewhere in the display area 13, and position detection means for detecting the position indicated by the user based on an image captured by the camera may be used. For example, the captured image is transmitted to the controller 20, and the CPU 21 of the controller 20 compares the icon data stored in advance in the storage unit 24 with the transmitted image, and the degree of coincidence between the two images is predetermined. When the threshold value is exceeded, processing may be performed assuming that the operation icon is instructed. This degree of coincidence may be calculated by a known algorithm such as pattern recognition.

  Further, a special pattern indicating the position is printed in advance inside the display area 13 of the display medium 10, and a camera built in the pen tip used by the user picks up the designated position and picks up the image. When the image is transmitted to the controller 20, the CPU 21 of the controller 20 extracts the special pattern from the captured image and analyzes it to calculate the coordinates in the display area 13 at the position indicated by the pen tip. May be. The special pattern may be drawn with small dots or the like so as not to affect the display content of the display medium 10 or may be drawn with a special pigment that does not reflect visible light. Examples of special pigments that do not reflect visible light include pigments that reflect only infrared light. In this case, for example, an infrared irradiation device in addition to the camera is built in the pen tip, and the pen is used. Irradiation with infrared rays may be performed at the position indicated by the tip, and the reflected light may be captured by a camera sensitive to the infrared rays.

  Moreover, you may use the apparatus using electromagnetic induction as a position detection means. For example, the display area 13 of the display medium 10 may be configured to detect wirings arranged in a grid and electromagnetic coils built in the intersections thereof, and an electric field generating device built in a pen point indicating the position. In this case, when an electric field generator is placed in the vicinity of the electromagnetic coil, a current flows through the electromagnetic coil. Therefore, the position is detected by measuring the current value or voltage value of the wiring connected to the electromagnetic coil. be able to.

(6) In the above aspect, only the drawing of the operation icon is mentioned, and the deletion of the operation icon is not particularly described. However, when the predetermined condition is satisfied, the display medium 10 deletes the operation icon. In addition, processing based on an operation icon instruction may be prohibited. For example, when the CPU 21 detects that a predetermined time has elapsed since the operation icon was displayed on the display medium 10 using a built-in timer, the scanning line driving circuit 11 and the data line driving circuit 12 are synchronized. The operation icon may be deleted. In this case, after erasing the operation icon, the image information last transmitted to the display medium 10 may be read from the VRAM 231 by the GPU 23 and re-transmitted to the display medium 10 to update the display in the display area 13.

  Further, the reference point for calculating the passage of the predetermined time is not limited to the time point when the operation icon is displayed. For example, the time point when the user's last instruction is detected by the position detection unit 15 may be used as the reference point. When there is no operation for a while, it is often the case that the user does not want to operate, so by doing as described above, the image information processing system 1 automatically infers the period during which the user does not want to operate The operation icon can be deleted.

  Further, an operation icon may be drawn when a predetermined time has elapsed from an arbitrary reference point. For example, an operation icon may be drawn when a predetermined time elapses with the time point when the display medium 10 displays content as a reference point. Immediately after the content display, the user wants to see the displayed content, and often does not want to be hindered by the operation icon displayed superimposed on the content. Therefore, by performing the above, the image information processing system 1 automatically recognizes a period during which the user does not want to draw the operation icon and draws the operation icon at an appropriate timing. Can do.

  In addition, as a configuration for detecting that a predetermined time has elapsed, for example, a threshold value is stored in the storage unit 24, and the elapsed time since the time when the CPU 21 determines whether or not the predetermined condition described above is satisfied, A timer (measuring unit) built in the CPU 21 measures, the elapsed time is compared with a threshold value read from the storage unit 24, and an additional pulse predetermined according to the comparison result may be supplied to the display medium 10. Further, the operation icon may be drawn or deleted when the elapsed time described above exceeds the threshold value. That is, an additional pulse (a set of identifiers of the scanning line driving circuit 11 and the data line driving circuit 12) may be supplied in accordance with the comparison result.

(7) In the above-described aspect, the controller 20 includes the CPU 21, the panel controller 22, the GPU 23, and the storage unit 24 in addition to the power supply unit 29. However, the controller 20 does not have to include all of these, The structure provided only with a part of may be sufficient. For example, the controller 20 may include a power supply unit 29 and a communication unit, and the communication unit may communicate with an external device including a CPU, a panel controller, a GPU, and a storage unit. In this case, the controller 20 and the above external device cooperate to function as a control means for controlling the display device.

(8) In the above aspect, the number of scanning lines SL connected to each scanning line driving circuit 11 and the number of data lines DL connected to each data line driving circuit 12 are both 256. However, the number of these is not limited to 256. Further, the number of scanning lines SL connected to the scanning line driving circuit 11 and the data lines DL connected to the data line driving circuit 12 may be the same or different.

  In the above-described aspect, the same number of scanning lines SL is connected to any scanning line driving circuit 11, but different numbers may be connected. Similarly, in the above-described aspect, the same number of data lines DL are connected to any data line driving circuit 12, but different numbers may be connected. In this case, since the drawing ranges of the sets of the scanning line driving circuit 11 and the data line driving circuit 12 are different from each other, for example, large icon data is prepared for frequently used operation icons and small for operation icons that are not frequently used. Freedom can be given to the design of the operation screen, such as preparing icon data.

(9) In the above-described aspect, the icon correspondence table 242 of the storage unit 24 of the controller 20 includes the identifiers of the operation icons and the identifiers of the scanning line driving circuit 11 and the data line driving circuit 12 that display the operation icons. Although the set is fixedly associated and stored, this correspondence may be rewritten as the processing proceeds. For example, this correspondence may be rewritten according to the number of times the operation icon is designated by the user. In this case, the icon correspondence table 242 is provided with a field for storing the number of times the operation icon is specified for each operation icon identifier. When the position detector 15 of the display medium 10 outputs position information indicating the position instructed by the user to the controller 20, the CPU 21 of the controller 20 specifies icon data instructed by this position information. Then, the CPU 21 reads the number of times corresponding to the identified identifier of the icon data from the icon correspondence table 242, adds 1 to this, and overwrites the icon correspondence table 242. The storage unit 24 stores a correspondence relationship between the range of the number of times an operation icon is designated in advance and each identifier set of the scanning line driving circuit 11 and the data line driving circuit 12, and the CPU 21 stores an icon correspondence table. The range to which the number of times of overwriting 242 belongs is specified in this correspondence relationship, and the set of identifiers corresponding to the range is overwritten in the icon correspondence table 242. Thus, since the position where the operation icon is drawn can be changed according to the frequency with which the operation icon is designated, an area in which frequently used operation icons are collected and displayed is provided in a predetermined area of the display area 13. You can also. In addition, when an image display unit is provided in the controller 20 as in the above-described modification, frequently used operation icons can be displayed on the image display unit. The operation icons displayed on the controller 20 may be used less frequently.

(10) In the above-described aspect, the scanning line driving circuit 11 and the data line driving circuit 12 may draw only a part of the scanning line group or the data line group corresponding to their own means when drawing the operation image data. Although partial rewriting was performed by driving, partial rewriting may not be performed. In other words, even when the operation image data is drawn, the scanning line driving circuit 11 and the data line driving circuit 12 do not skip all the scanning lines SL and data lines DL connected to the own unit. It may be driven.
