(Configuration of display image 120)
FIG. 3 is a schematic diagram related to the regulation frame static management table and the display image before execution of the application according to the embodiment of the present invention. The display image 120 represents an image displayed on the display screen 12, and the specified frame static management table 140 (region management table) in FIG. This is created by the coordinate management unit 14, and after the application 150 is executed, the coordinate management unit 14 creates a specified frame management table to be described later.

  The display image 120 is a button bar 121 that displays buttons for reducing / enlarging the display image 120, a display frame 122 that is an area in which the image is displayed, and a display that is an area in which the image is displayed in the display frame 122. An area 123 and first to third regulation frames 124 to 126, which are regulation frames for displaying images, are schematically configured. Here, the defined frame (a plurality of regions) is a region having a predetermined size in the display region 123 defined by the coordinate management unit 14, and this region (the first to third defined frames 124 to 126). The image assigned in () is displayed. Further, as shown in FIG. 3, it is assumed that the first regulation frame 124 is given the symbols “a”, “b”, and “c” in the order of the table number 141 of the regulation frame management table 140. In the following, the definition frame refers to all the definition frames including the first to third definition frames 124 to 126 set in the display area 123.

(Configuration of the regulation frame static management table 140)
The specified frame static management table 140 is static data to be described later, and includes a table number 141 that is a table number, a specified size 142 indicating the size of an assignable image (size at the time of display), and a display area 123. And a block position 143 indicating the origin of coordinates of the first to third defined frames 124 to 126 in the XY coordinates which are orthogonal coordinates set in a grid pattern. The origin of the XY coordinates is the upper left of the display area 123, and the XY coordinates increase or decrease by 1 as the grid moves by 1 square. In addition, the coordinate origin of the first to third defined frames 124 to 126 is assumed to be at the upper left of each frame.

  For example, the prescribed size 142 is “A” for the first prescribed frame 124, “B” for the second prescribed frame 125, and “C” for the third prescribed frame 126, and the prescribed size 142 is “A”. This image can be displayed in the first prescribed frame 124.

(Configuration of the regulation frame management table 140a)
FIG. 4 is a schematic diagram relating to the specified frame management table and the display image after execution of the application according to the embodiment of the present invention. The defined frame management table 140a in FIG. 4 represents the defined frame static management table 140 updated after the application 150 is executed, and includes static data 140A and dynamic data 150A. The specified frame static management table 140 in FIG. 3 is static data 140A and is set when the application 150 is designed.

  The specified frame management table 140a includes a used flag 144, an image ID 145 for identifying an image, a priority 146 indicating the priority for displaying images, and an image in addition to the above-described specified frame static management table 140. And a counter value 147 as a predetermined value that is a value for controlling display / non-display. The used flag 144, the image ID 145, the priority 146, and the counter value 147 are dynamic data 150A, and are values that change as the application 150 is executed.

  The used flag 144 indicates whether or not an image is displayed in the first to third specified frames 124 to 126 assigned to the table number 141, and “T” indicates that it has been used. “F” indicates that it is not used.

(Operation)
Hereinafter, the operation of the image display apparatus according to the present embodiment will be described in detail with reference to FIGS. 1 to 4 and FIGS.

(Prerequisite)
FIG. 5 is a schematic diagram showing information of a displayed image according to the embodiment of the present invention. First, preconditions regarding the operation of the image display apparatus 1 described below will be described.

(1) A processing unit of the application 150 is called a frame, and a series of processing is executed by the control unit 10 in each frame.
(2) Before starting a series of processes in each frame, the application 150 issues a refresh request to the coordinate management unit 14. Thereby, the refresh process of the regulation frame management table 140a managed by the coordinate management unit 14 is executed. The refresh request is to clear the used flag 144 recorded in the specified frame management table 140a.
(3) Although the specified size 142 and the block position 143 are recorded as the static data 140A in the specified frame management table 140a, these are set at the time of rough design. When the application 150 is executed, a used flag 144, an image ID 145, a priority 146, and a counter value 147 are recorded as the dynamic data 150A.
(4) The specified size 142 can be arbitrarily defined. In the following, it is assumed that the first specified frame 124 is set as the same specified size 142 “A” as shown in FIG. , A, b and c, respectively. Further, it is assumed that the prescribed frame management table 140a is recorded in the order of a → b → c. In the present embodiment, the assignment of the first prescribed frames 124 “a”, “b”, and “c” will be described, but the same processing is performed for other prescribed frames.
(5) It is assumed that the application 150 displays four images within one frame. As shown in FIG. 5, the image information of the image 1 is that the image ID 145 is “ID1” and the priority 146 is “ 1 ”, specified size 142 is“ A ”, image 2 is image ID 145“ ID2 ”, priority 146 is“ 2 ”, specified size 142 is“ A ”, image 3 is image ID 145 is“ ID3 ”, priority Assume that the degree 146 is “1”, the specified size 142 is “A”, the image 4 is “ID4”, the priority 146 is “2”, and the specified size 142 is “A”.

(First method)
FIG. 6A is a diagram showing a dynamic data table according to the embodiment of the present invention, and FIG. 6B is a diagram showing an image allocation table according to the embodiment of the present invention. The dynamic data table 140b represents the dynamic data 150A for each frame in the specified frame management table 140a, and the image allocation table 140c represents “allocation request order”, “allocated image”, and “not allocated” for each frame. "Image". Note that the image allocation table 140c in FIG. 6B is a diagram for explaining the present embodiment, and is not created during the execution of the application 150 in practice. The same applies to FIGS. 8B and 10B described later. A first method for unconditionally assigning an image to the first prescribed frame 124 based on the order in which the image display position assignment request is received first will be described with reference to the flowchart shown in FIG.

  First, the designer of the application 150 divides the display area 123 into a plurality of areas via the operation unit 13 at the time of rough design, and the coordinate management unit 14 manages the specified frame static management based on the plurality of divided areas. Create table 140 (static data 140A) (creation step)

(At the start of frame 1)
The control unit 10 reads the application 150 from the storage unit 15 and executes it (S1). As shown in FIG. 4, the application 150 requests the coordinate management unit 14 to refresh the specified frame management table a at the start of frame 1 (S2). At this time, since the prescribed frame management table 140a is still in the initial state, the contents are not changed.

(Frame 1 processing)
The application 150 requests the coordinate management unit 14 to display the images 1 to 4 in the order of the images 1 to 4 shown in FIG. 5 as predetermined images. First, in order to display the image 1, the application 150 sets the information of the image 1 as “image ID 145 = 1, priority 146 = 1, specified size 142 = A”, as shown in FIG. A display position allocation request (display request) is made (S3). In the present embodiment, the images 1 to 4 are taken as examples of the predetermined image, but the present invention is not limited to this, and a predetermined character string may be used.

  The coordinate management unit 14 determines that all the “A” defined frames (the first defined frames 124 “a”, “b”, and “c”) of the defined size 142 in the dynamic data table 140b of the defined frame management table 140a are all. Since it is unused (used flag 144 = F), the first specified frame 124 “a” at the upper level registered in the specified frame management table 140a is assigned to image 1 (S4; first selection step).

  The coordinate management unit 14 changes the used flag 144 of the dynamic data 150A in the table number 141 “0” of the defined frame management table 140a to “T” and updates it to “image ID 145 = ID1, priority 146 = 1”. (S5).

  The coordinate management unit 14 transmits coordinates capable of displaying the image 1 to the application 150 based on the prescribed frame management table 140a, and the application 150 receives the received first prescribed frame 124 “a” as shown in FIG. The image 1 is displayed on the display screen 12 based on the coordinate values (S6).

  Subsequently, when there is a display position allocation request for other images (image 2 and image 3) (S7; Yes), the application 150 performs step 3 for each of the other images (image 2 and image 3) for which there is a display position allocation request. Process from.

  Here, in step 7, when there is no display position allocation request (S7; No), the processing of the next frame proceeds.

  After the processing from step 3 to step 7 is repeated, when the display position of image 3 is assigned, the specified size 142 “A” of the specified frame management table 140a cannot be assigned. Therefore, when the display position allocation request for the image 4 is made from the application 150, the coordinate management unit 14 transmits a signal indicating “no allocation” to the application 150. At this time, the image 4 is not displayed.

  In the frame 1 by the above processing, as shown in the image assignment table 140c in FIG. 6B, the image 4 is not assigned, and the images 1, 2, and 3 are displayed.

(At the start of frame 2)
The application 150 performs the refresh process in step 2 when performing the next frame process (S8; Yes). Since the coordinate management unit 14 clears all the used flags 144 in the defined frame management table 140a, the first defined frame 124 shifts to a state where it can be assigned.

  If the frame process is not performed in step 8, the process ends (S8; No).

(Frame 2 processing)
The case where the display position allocation request for the image 3 is not executed and the display position allocation request is made in the order of image 1 → image 2 → image 4 will be described.

  When the “frame 2 process” is a process that does not display the image 3, the application 150 issues a display position assignment request for the images 1, 2, and 4 to the coordinate management unit 14.

  At this time, the display positions of the images 1 and 2 are assigned by the processing of step 3 and step 4, and the coordinate management unit 14 gives the application 150 the coordinates at which the images 1 and 2 can be displayed based on the specified frame management table 140a. The application 150 displays the image 1 on the display screen 12 via the display unit 11 at the designated coordinates based on the received coordinates.

  The image 4 is assigned to the first prescribed frame 124 “c” and displayed because the first prescribed frame 124 “c” to which the image 3 was assigned is empty (used flag 144 = F). The

  In the frame 2, as shown in the image allocation table 140c in FIG. 6B, since there was no display position allocation request for the image 3, there is no unallocated image, and the images 1, 2, and 4 are displayed. The

(At the start of frame 3)
The coordinate management unit 14 performs the refresh process in step 2 in the same manner as “at the start of frame 2”. The coordinate management unit 14 clears all the used flags 144 in the defined frame management table 14a, and the first defined frame 124 shifts to a state where it can be assigned.

(Frame 3 processing)
Frame 3 is performed in the same manner as “Frame 1 processing”. As a result, as shown in the image allocation table 140c in FIG. No. 4 is not assigned a specified frame.

(Second method)
FIG. 8A is a diagram showing a dynamic data table according to the embodiment of the present invention, and FIG. 8B is a diagram showing an image allocation table according to the embodiment of the present invention. A second method for occupying an image in the specified frame even if there is no display position allocation request for the image previously allocated will be described with reference to the flowchart shown in FIG. When there is no allocation request for a certain period, the allocation is released.

(At the start of frame 1)
The same process as “at the start of frame 1” in the first method is performed.

(Frame 1 processing)
The application 150 and the coordinate management unit 14 perform the processing from step 2 to step 3 in the first method. After the image display position is assigned in step 3, the coordinate management unit 14 sets the counter value 147 in the process 2 of frame 1 shown in FIG. 7A to the initial value N (N = 2 in FIG. 7A). (S10; recording step). At this time, as shown in FIG. 7B, the image 4 is not displayed as in the “frame 1 process” of the first method.

(At the start of frame 2)
The application 150 makes a refresh request to the coordinate management unit 14 (S11). At this time, the coordinate management unit 14 clears all the used flags 144 of the defined frame management table 140a in response to the refresh request, shifts the first defined frame 124 to a state where it can be assigned, -1 is added to the counter value 147 of the defined frame (S12). As shown in the dynamic data table 140b shown in FIG. 7A, the counter values 147 are all “1” in the frame 2.

(Frame 2 processing)
Similar to the “frame 2 process” of the first method, a case where the display position allocation request for the image 3 is not made will be described.

  At this time, the display positions of the images 1 and 2 are assigned by the processing of Step 3 and Step 4 described above (S13). The coordinate management unit 14 sets the counter value 147 of the assigned specified frame to the initial value N (= 2).

  The application 150 makes a display position allocation request for the image 4 to the coordinate management unit 14. As shown in FIG. 7A, the coordinate management unit 14 is in a state where the first specified frame 124 “c” is empty (used flag 144 = F), but the counter value 147 is larger than zero ( S14; Yes), no assignment is performed (determination step). The first specified frame 124 “c” at this time is referred to as an occupied state of the image 3. This occupied state is a state in which the specified frame is unused (used flag 144 = F), but an image ID is assigned, and the assigned image is not displayed. At this time, the image 4 is not displayed as shown in FIG.

  Here, when the counter value 147 is smaller than zero in Step 14 (S14; No), the image 4 is displayed in the first specified frame 124 “c” (S15).

(At the start of frame 3)
The same processing as “at the start of frame 2” in the second method is performed.

(Frame 3 processing)
Similar to the “frame 2 process” of the first method, a case where the display position allocation request for the image 3 is not made will be described.

  At this time, the display positions of the images 1 and 2 are assigned by the processing in step 3 and step 4 described above. The counter value 147 of the assigned regulation frame is set to the initial value N (= 2).

  The application 150 makes a display position allocation request for the image 4 to the coordinate management unit 14. As shown in FIG. 7A, the coordinate management unit 14 has the first prescribed frame 124 “c” in an empty state (used flag 144 = F) and the counter value 147 is zero. Image 4 is assigned to the first defined frame 124 “c”. At this time, the occupied state of the image 3 in the first specified frame 124 “c” is released. As a result, as shown in the image allocation table 140c in FIG. 7B, all images for which display position allocation is requested are allocated to the specified frames, and images 1, 2, and 4 are displayed.

  By performing the second method, for example, when frame processing is not performed for each frame due to conditional branching, or when image processing does not end within the time of one frame and the displayed image drops, It is possible to prevent the display screen 12 from flickering without causing replacement of images assigned to frames.

(Third method)
FIG. 10A is a diagram showing a dynamic data table according to the embodiment of the present invention, and FIG. 10B is a diagram showing an image allocation table according to the embodiment of the present invention. The third method is similar to the second method described above, but compares the priority of the image in the occupied state and the requested image for assignment during the period in which the occupied state continues, and determines whether or not to assign. A method is demonstrated according to the flowchart of FIG.

  Here, the coordinate management part 14 shall have a threshold value. This threshold value is a value set for the counter value 147. In the present embodiment, the threshold value = 1. The threshold value is a numerical value for setting a time during which the image can occupy the specified frame (maximum time for which the occupation state continues), and is set to a positive integer smaller than the initial value N. When the counter value 147 of the specified frame is in the range of initial value ≧ counter value> threshold value, the image that has been previously assigned and is in the occupied state is given the occupation right, but the counter value ≦ the threshold value range When there is a request for assigning an image with a high priority 146, the occupation is released. Here, for example, if threshold = 0, it is equivalent to the second method, and when threshold = initial value, it is assigned to an image with a high priority 146 regardless of the occupied image. It can be performed.

(At the start of frame 1)
The same process as “at the start of frame 1” in the second method is performed.

(Frame 1 processing)
With the initial value N = 3, processing similar to “Frame 1 processing” in the second method is performed.

(At the start of frame 2)
Processing similar to “at the start of frame 2” in the second method is performed.

(Frame 2 processing)
Similar to the “frame 2 process” of the first and second methods, a case where a display position allocation request for the image 3 is not made will be described.

  The coordinate management unit 14 assigns the first specified frames 124 “a” and “b” to the images 1 and 2. At this time, since there is no display position allocation request for the image 3 in the first specified frame 124 “c”, the image 3 is occupied as shown in FIG.

  Subsequently, the application 150 makes a display position allocation request for the image 4 to the coordinate management unit 14.

  The coordinate management unit 14 determines whether or not to allocate a display position allocation request for the image 4. As shown in FIG. 8A, the coordinate management unit 14 refers to the counter value 147 of the first specified frame 124 “c” and compares it with the threshold value (= 1). The coordinate management unit 14 does not assign the image 4 because the counter value 147 of the first specified frame 124 “c” is 2 and is larger than the threshold value. Therefore, as shown in the image allocation table 140c of FIG. 8B, nothing is displayed in the first specified frame 124 “c”, and the image 4 is not displayed.

(At the start of frame 3)
The same process as “at the start of frame 2” in the third method is performed (S20 to S21).

(Frame 3 processing)
A case where the application 150 issues a display position assignment request in the order of image 1 → image 4 will be described.

  The coordinate management unit 14 performs processing similar to the “frame 2 processing” of the third method, and assigns the image 1 to the first specified frame 124 “a” (S22).

  The coordinate management unit 14 determines whether or not the image 4 can be assigned to a stipulated frame (in this case, the first stipulated frame 124 “b”) positioned higher than the stipulated frame management table 140 a among the vacant defined frames. Judgment is made.

  From the dynamic data table 140b shown in FIG. 8A, the coordinate management unit 14 determines that the counter value 147 (= 2) of the first specified frame 124 “b” in the frame 3 is greater than the threshold value (= 1). Therefore, it is determined that the image 4 cannot be assigned to the first specified frame 124 “b”.

  Subsequently, the coordinate management unit 14 determines whether it is possible to assign to the first specified frame “c” positioned next higher.

  Since the counter value 147 (= 1) of the first defined frame 124 “c” in the frame 3 is equal to or less than the threshold value (= 1) (S23; No), the coordinate management unit 14 continues to the occupied state. The priority 146 of a certain image 3 is compared with the priority 146 of the image 4 (second selection step). As shown in FIG. 5, the coordinate management unit 14 assigns the image 4 to the first specified frame 124 “c” because the priority of the image 4 is higher than that of the image 3 (S24; Yes). 2 selection step). At this time, since there is no display request for the image 2, the images 1 and 4 are displayed on the display screen 12 (S25).

  Here, in step 23, when the counter value 147 is equal to or larger than the threshold value (S23; Yes), the image 4 is not assigned. In step 24, when the priority 146 is low (S24; No), the image 4 is not assigned.

(At the start of frame 4)
The same processing as “at the start of frame 2” in the third method is performed.

(Frame 4 processing)
A case where the application 150 issues a display position assignment request in the order of image 1 → image 3 → image 4 will be described.

  The coordinate management unit 14 performs the same process as the “frame 2 process” of the third method, and assigns the image 1 to the first specified frame 124 “a”.

  Since the counter value 147 (= 1) of the vacant first prescribed frame 124 “b” is equal to or less than the threshold value (= 1), the coordinate management unit 14 sets the first prescribed frame 124 “b” to the first prescribed frame 124 “b”. On the other hand, the priority 146 (= 2) of the image 2 in the occupied state and the priority 146 (= 1) of the image 3 are compared. The coordinate management unit 14 does not assign the image 3 because the priority 146 of the image 2 is large.

  Since the image 4 is in the occupied state with respect to the first prescribed frame 124 “c”, the coordinate management unit 14 assigns the image 4 to the first prescribed frame 124 “c”. In this case, the images 1 and 4 are displayed from the image allocation table 140c shown in FIG. 8B, and the image 3 is not allocated.

(At the start of frame 5)
Processing similar to “at the start of frame 2” in the third method is performed. Here, when -1 is added to the counter value 147, the information of the occupied image (image ID 145 and priority 146) is cleared in the specified frame where the counter value 147 becomes zero. This corresponds to, for example, “frame 4 processing” of the first specified frame 124 “b”, and the image ID 145 and the priority 146 are set to “no data” at the subsequent “start of frame 5”.

  Here, a method of not clearing the information of the image of the specified frame in which the counter value 147 is zero can be considered. By not clearing the image, the image can be displayed again in the specified frame once used regardless of the elapsed time. However, when the application 150 makes a display position allocation request for another image, the occupied state is released.

(Frame 5 processing)
A case where the application 150 issues a display position assignment request in the order of image 1 → image 3 → image 4 will be described.

  The coordinate management unit 14 performs processing similar to the “frame 2 processing” of the third method, and assigns the image 1 to the first specified frame 124 “a”.

  The coordinate management unit 14 assigns the image 3 to the first prescribed frame 124 “b” because there is no occupied image in the empty prescribed frame (in this case, the first prescribed frame 124 “b”).

  The coordinate management unit 14 performs processing similar to the “frame 4 processing” of the third method, and assigns the image 4 to the first specified frame 124 “c”. At this time, as shown in the image allocation table 140c in FIG. 8B, the images 1, 2, and 4 are displayed on the display screen 12, and there is no image that cannot be allocated.

(effect)
According to the above-described embodiment, the display screen can be designed in advance when the application 150 is roughly designed. In addition, since the processing result at an arbitrary timing can be displayed, debugging efficiency at the time of application development (software development) can be improved.

  Although the image display device 1 has been described in the present embodiment, the image display device 1 may be implemented as an image display method or an image display program executed by an electronic device such as a computer having a CPU (Central Processing Unit).

  The present invention is not limited to the above-described embodiments and modifications, and various modifications can be made without departing from or changing the technical idea of the present invention.
