  The display control apparatus according to the present embodiment is an apparatus that is employed in the information processing apparatus 1, for example, as illustrated in FIG. The display control device 100 is a device that displays an image on the display device 300.

  The information processing apparatus 1 is a monitoring apparatus that monitors equipment in a building, for example, and displays a monitoring screen (display screen) S on the display device 300 as shown in FIGS. On the monitoring screen S, a list L indicating a history of monitoring results at each place in the building is displayed. In the example of FIG. 2, it is displayed that some abnormality has occurred in the equipment set in “4: Corridor East”.

  When the display device 300 slides the list L on the display device 300 (a kind of animation display), for example, the frame rate is changed, or as shown in FIG. By replacing with a simple image, the load of the drawing process of the display device 300 is reduced. Hereinafter, the configuration of the information processing apparatus 1 including the display control apparatus 100 will be described.

  As illustrated in FIG. 1, the information processing device 1 includes a display control device 100 that controls the display device 300, an operation reception device 200 that receives a user operation, and a display device 300 that displays information provided to the user. Prepare. The operation reception device 200 and the display device 300 are electrically connected to the display control device 100 via a communication line C such as a bus.

  The display control device 100 includes a control unit 10 that performs overall control of each component included in the display control device 100, a storage unit 20 that stores various programs, data used when these programs are executed, and a communication line C. And an I / O (Input / Output) controller 30 for controlling communication with peripheral devices such as an operation receiving device 200 and a display device 300 connected via the network. These components are connected via a bus 40.

  The control unit 10 includes a CPU, a RAM (Random Access Memory), a ROM (Read Only Memory), and the like. The control unit 10 is monitored from a functional unit (not shown) for monitoring the operation state of each facility in the information processing apparatus 1 by executing various programs stored in the storage unit 20 using the RAM as a work area. The information is received, and the monitoring screen S indicated by the received monitoring information is displayed. Further, the control unit 10 executes processing for reducing the load of drawing processing in the display device 300.

  The storage unit 20 includes, for example, a readable / writable nonvolatile semiconductor memory such as a flash memory, an HDD (Hard Disk Drive), or the like. The storage unit 20 stores various programs and further stores various data used for the processing of the control unit 10.

  The I / O controller 30 includes a processor for controlling communication between the display control device 100 and peripheral devices. The I / O controller 30 receives information indicating a user operation from the operation reception device 200 and sends it to the control unit 10. Further, the I / O controller 30 transmits a drawing instruction corresponding to the received information to the display device 300 according to an instruction from the control unit 10.

  The operation reception device 200 is, for example, a touch panel, a keypad, a touch pad, a button, a switch, a mouse, a keyboard, a camera for recognizing a user's gesture, a distance sensor, and a communication that receives input from another device at a remote location. An input device such as a device is configured to receive an input operation from a user and send a signal related to the received input operation to the display control apparatus 100.

  The display device 300 includes a display device such as an LCD (Liquid Crystal Display), for example, and displays information to be provided to the user under the control of the display control device 100. In the present embodiment, the operation reception device 200 and the display device 300 are capacitive touch panels having an operation reception function and a display function, and the user touches the coordinates touching the display screen S. A user operation is accepted by detecting the number of points, the direction of tracing the display screen S, and the like.

  2 and 3, the upper left corner of the display screen S of the display device 300 is the origin, the width (horizontal) direction from the origin is the x axis, and the height (vertical) direction is the y axis. The number of pixels on the display screen S is 320 pixels wide and 240 pixels high.

  The display screen S has a plurality of display areas. For example, as shown in FIGS. 2 and 3, a list display area 310 for displaying a list L and a portion displayed in the list display area 310. And a scroll area 320 indicating the position in the height direction (y direction).

  When the list L does not fit in the list display area 310, the user can display a desired item of the list L by sliding the list L in the list display area 310. The scroll area 320 includes a knob 321, and the position and ratio of the height direction in the entire portion displayed in the list display area 310 according to the position of the knob 321 in the scroll area 320 and the length in the y direction. Is shown visually.

  In the present embodiment, it is assumed that the list L and the knob 321 displayed in these areas can be slid only in the y direction.

  The display control apparatus 100 included in the information processing apparatus 1 exhibits various functions by having the above-described configuration. A functional configuration of the display control apparatus 100 will be described with reference to FIG.

  The display control device 100 includes an operation feature extraction unit 110 that extracts operation features from the operation information acquired from the operation reception device 200, and a determination unit 120 (parameter setting) that determines the movement (animation) of an image displayed on the display device 300. Means), an adjustment unit 130 for adjusting the display mode of the animation image displayed on the display device 300, an image correction table 131 in which a correction method of the animation image is set, and a frame rate table in which the frame rate of the animation image is set 132 and a drawing instruction unit 140 that outputs a drawing instruction of the adjusted animation image to the display device 300.

The operation feature extraction unit 110 is realized mainly by the cooperation of the control unit 10 and the I / O controller 30. When the operation feature extraction unit 110 acquires the operation information indicating the user operation from the operation reception device 200, the operation feature extraction unit 110 extracts the feature of the user operation from the acquired information and sends the operation feature information indicating the extracted feature to the determination unit 120. Here, the characteristics of the user operation include the type of operation (for example, swipe, slide, drag, pinch in / out, tap, etc.), start point, end point, direction, operation speed _{vo, and the} like.

The determination unit 120 is mainly realized by the control unit 10. Based on the operation feature information sent from the operation feature extraction unit 110, the determination unit 120 generates (sets) animation information (operation parameters) that characterizes the movement of the image displayed on the display device 300. The determination unit 120 displays, for example, an animation speed v _d indicating the speed of movement of the animation image, a total movement amount L _d indicating the distance that the animation image slides by a single user operation, a direction in which the animation image slides, and the like. It is calculated for each area and sent to the adjustment unit 130 and the drawing instruction unit 140 as animation information.

  The adjustment unit 130 is mainly realized by the control unit 10. When the adjustment unit 130 receives the animation information from the determination unit 120, the adjustment unit 130 refers to the image correction table 131 and the frame rate table 132 to adjust the display mode of the animation image for each display area. For example, the adjustment unit 130 performs adjustments such as replacing character elements and image elements included in the animation image of each display area with a substitute image or changing the frame rate. The adjustment unit 130 sends adjustment information indicating the adjusted display mode to the drawing instruction unit 140.

The image correction table 131 is a data table and is stored in advance in the storage unit 20, for example. The image correction table 131, as shown in the example of FIG. 5, for each display area, the correction method corresponding to the animation speed v _d is set. For example, for the list display area 310, when the animation speed v _d determined by the determination unit 120 is 30 dps (dots per second), the character element included in the animation image is a dummy image (an image similar to a sliding character). When the animation speed v _d is 50 dps, the image element included in the animation image is set to be replaced with a monochrome rectangular image. Further, for example, the scroll area 320, when the animation speed v _d the decision unit 120 has decided is 60dps is set may not be corrected any image element. Note that “...” In the figure corresponds to an image with a lower drawing load than a single-color rectangular image or a dummy image. For example, an image having a lower resolution than the default single-color rectangular image or dummy image is applicable.

In general, the animation speed v _d of the list display area 310, greater than animation speed v _d of the scroll area 320, there is a tendency that the user does not view the list display area 310 every detail. Therefore, by replacing the image elements and character elements included in the animation image in the list display area 310 with an alternative image having a low processing load, the drawing processing load can be reduced overall. Also, in the scroll area 320, when the animation speed v _d is high (for example, when v _d is 75 dps or more), the image element or the character element may be replaced with a substitute image.

  The frame rate table 132 is a data table, and is stored in advance in the storage unit 20, for example. In the frame rate table 132, as shown in the example of FIG. 6, the frame rate of the animation image is set for each display area. Here, 10 fps (frames per second) is set in the list display area 310, and 30 fps is set in the scroll area 320.

  In general, the area of the list display area 310 is larger than the area of the scroll area 320. Thus, by lowering the frame rate of the large list display area 310, it is possible to reduce the overall drawing processing load. Further, by setting the frame rate of the scroll area 320 having a small area relatively high, a smooth operation response can be realized.

  The drawing instruction unit 140 is realized mainly by the cooperation of the control unit 10 and the I / O controller 30. When the drawing instruction unit 140 receives the animation information from the determination unit 120 and receives the adjustment information from the adjustment unit 130, the drawing instruction unit 140 adjusts the animation image indicated by the animation information in the display mode indicated by the adjustment information, and the display device 300 for each frame. The drawing instruction is output to.

  Next, the operation of the information processing apparatus 1 having the above configuration will be described with reference to FIGS. 8 to 12, taking the case where the user performs the operation shown in the example of FIG. 7 as an example.

  The operation reception device 200 acquires information indicating whether or not the user is touching the operation surface and information indicating the position where the user is touching at predetermined intervals (for example, every 0.2 seconds). . FIG. 7 shows an example in which the user touches the operation surface on the list display area 310, quickly moves the touching finger upward, and then releases the finger from the operation surface, so-called a swipe operation. . The operation reception device 200 sends operation information received from the user to the display control device 100.

  When the operation feature extraction unit 110 of the display control apparatus 100 acquires the operation information from the operation reception apparatus 200, the display control process illustrated in FIG. In the present embodiment, when the user performs a swipe operation on the operation reception device 200, the animation image displayed on the display device 300 slides at a constant speed (constant speed slide) and then stops.

  When the display control process starts, first, the operation feature extraction unit 110 performs an operation feature extraction process for extracting a feature of a user operation (step S100). When the operation feature extraction unit 110 extracts the feature of the user operation, the determination unit 120 performs an animation determination process for determining an animation determined based on the extracted operation feature (step S200).

  Subsequently, the adjustment unit 130 performs display mode adjustment processing for adjusting the display mode of the animation image based on the animation determined in the animation determination processing (step S300). When the adjustment unit 130 adjusts the display mode, the adjustment unit 130 and the drawing instruction unit 140 cooperate to perform a drawing instruction process for instructing the display device 300 to draw an animation image (step S400). The details of each of the above processes will be described below.

<Operation feature extraction processing>
With reference to FIG. 9, an operation feature extraction process that starts when the operation feature extraction unit 110 acquires operation information from the operation reception device 200 will be described in detail. First, the operation feature extraction unit 110 determines the type of user operation from the acquired operation information (step S101). For example, as illustrated in the example of FIG. 7, the operation feature extraction unit 110 may be used when the user operation is completed within a predetermined time (for example, 0.6 seconds to 1.0 seconds). It is determined that the operation is a swipe operation.

  Subsequently, the operation feature extraction unit 110 extracts the start point of the user operation from the operation information (step S102). From the operation information shown in the example of FIG. 7, (160, 200) is extracted as the operation start point.

  Further, the operation feature extraction unit 110 extracts the direction of the user operation from the operation information (step S103). In the example of the operation information shown in FIG. 7, when the coordinate value (160, 200) of the operation start point is subtracted from the coordinate value (160, 150) of the operation end point, it is (0, -50). The direction is determined to be the upward direction.

Further, the operation feature extraction unit 110 extracts the operation speed _vo from the operation information (step S104). In the example of the operation information shown in FIG. 7, the operation speed _vo is determined to be 50 dps since the movement from the start point to the end point of the user operation takes 1.0 seconds.

The operation feature extraction unit 110 extracts information {operation: swipe, start point: (160, 200), direction: up, v _o : 50 dps} from the operation information.
Is sent to the determination unit 120 as operation feature information. Thereafter, the process proceeds to an animation determination process.

<Animation decision processing>
With reference to FIG. 10, an animation determination process that starts when the determination unit 120 acquires operation feature information from the operation feature extraction unit 110 will be described in detail.

When determining the operation feature information from the operation feature extraction unit 110, the determination unit 120 first calculates the animation speed v _d and the total movement amount L _d of the animation image displayed in the list display area 310 from the acquired operation feature information. (Step S201). For example, the determination unit 120 calculates the animation speed v _d and the total movement amount L _d from the user's operation speed v _{o as} represented by the following equation.
v _d = v _o [dps]
L _d = 0.4 v _o [pixel]

Here, since the user operation speed _vo indicated by the operation feature information is 50 dps, the animation speed v _d is calculated to be 50 dps, and the total movement amount L _d is calculated to be 20 pixels.

Subsequently, the determination unit 120 calculates the animation speed v _d and the total movement amount L _d of the animation image displayed in the scroll area 320 (step S202). Since the scroll area 320 indicates the position in the height direction of the entire portion displayed in the list display area 310, the animation speed v _d and the total movement amount L _d on the scroll area 320 are the list display area. This is calculated according to the amount of data displayed at 310. Here, it is assumed that the animation speed v _d on the scroll area 320 is calculated to be 30 dps and the total movement amount L _d is 20 pixels.

The determination unit 120 sends the animation speed v _d and the total movement amount L _d calculated for each display area to the adjustment unit 130 and the drawing instruction unit 140 as the following animation information. Thereafter, the processing shifts to display mode adjustment processing.
{Display area: List display area, Direction: Up, v _d : 50 dps, L _d : 20 pixels}
{Display Area: scroll area, direction: _{down, v d: 30dps, L d} : 20 pixels}

<Display mode adjustment processing>
With reference to FIG. 11, the display mode adjustment process that starts when the adjustment unit 130 acquires animation information from the determination unit 120 will be described in detail.

  When acquiring the animation information from the determination unit 120, the adjustment unit 130 first determines an image correction method and a frame rate for the list display area 310 (step S301).

More specifically, the adjustment unit 130 refers to the image correction table 131 and extracts an image correction method. Because animation speed v _d of the list display area 310 is a 50Dps, adjustment unit 130 determines to replace the image elements included in the animation image in monochrome rectangular image, the character element the dummy image. Further, the adjustment unit 130 refers to the frame rate table 132 and determines the frame rate to be 10 fps.

  Subsequently, the adjustment unit 130 determines an image correction method and a frame rate for the scroll area 320 (step S302).

Here, since the animation speed _{v d} of the scroll area 320 is a 30Dps, adjusting section 130 determines not to set an image correction method. Further, the adjustment unit 130 refers to the frame rate table 132 and determines the frame rate to be 30 fps.

The adjustment unit 130 sends the image correction method and the frame rate calculated for each display area to the drawing instruction unit 140 as the following adjustment information. Thereafter, the process proceeds to a drawing instruction process.
{Display area: List display area, Image: Monochromatic rectangular image, Character: Dummy image, Frame rate: 10 fps}
{Display area: List display area, Image: No correction, Character: No correction, Frame rate: 30 fps}

<Drawing instruction processing>
With reference to FIG. 12, the drawing instruction process that starts when the drawing instruction unit 140 acquires animation information from the determination unit 120 and acquires adjustment information from the adjustment unit 130 will be described in detail. Note that the drawing instruction process is executed for each display area. Here, an example of the drawing instruction process in the list display area 310 will be described.

  First, the drawing instruction unit 140 adjusts the animation image indicated by the acquired animation information in the display mode indicated by the acquired adjustment information, and outputs the drawing instruction of the first frame (frame number i = 1) to the display device 300. (Step S401). When the drawing instruction unit 140 outputs a drawing instruction for the first frame, the adjustment unit 130 increments the frame number (i = 2) (step S402).

Subsequently, the adjustment unit 130 calculates a remaining movement amount l ₂ representing the remaining distance to be slid for the frame having the incremented frame number (i = 2) (step S403).
The remaining movement amount l ₂ is obtained by subtracting the movement amount m _d per frame from l ₁ (that is, the total movement amount L _d ).
l _{i + 1} = l _i −m _d [pixel]
l ₂ = L _d −m _d [pixel]

The movement amount m _d per frame is obtained by dividing the animation speed v _d by the frame rate. Here, since the animation speed v _d is 50 dps and the frame rate is 10 fps, the movement amount m _d is calculated as 5 pixels. Therefore, the remaining movement amount l ₂ is calculated as 15 pixels for the frame having the slide number of i = 2.

After calculating the remaining movement amount l ₂ , the adjustment unit 130 determines whether or not the value of the remaining movement amount l ₂ is greater than 0 (step S404). Here, since the value of the remaining movement amount l ₂ is 15, the drawing instruction processing step proceeds to step S401.

In step S401, after the drawing instruction for the first frame is output, the drawing instruction unit 140 has passed a period (0.1 seconds if the frame rate is 10 fps) that is the inverse of the frame rate indicated by the adjustment information. Then, a drawing instruction for the second frame is output to the display device 300 (step S401). The second frame is an image adjusted by the image correction method indicated by the adjustment information after moving the first frame upward by the movement amount m _d (5 pixels).

Thereafter, the processes in steps S401 to S404 are repeated until it is determined that the value of the remaining movement amount l _{i + 1} calculated in step S403 has become 0 or less (No in step S404).

When the value of the remaining movement amount l _{i + 1} calculated in step S403 becomes 0 or less (No in step S404), the adjustment unit 130 sends an animation end notification indicating that the animation display is ended to the drawing instruction unit 140 (step S404). S405).

  Upon receiving the animation end notification from the adjustment unit 130, the drawing instruction unit 140 outputs an instruction to cancel the adjustment to the display device 300 (step S406).

  The drawing instruction process described above is similarly executed for the scroll area 320.

  As described above, in the present embodiment, the adjustment unit 130 is configured to adjust the display mode of the animation image determined by the user operation. Thereby, the load of the drawing process of an animation image can be reduced, and smooth animation display can be realized even when the drawing processing capability of the display device 300 is low.

In this embodiment, the adjustment unit 130 refers to the image correction table 131, but when the animation speed v _d is large, and a structure for displaying a simplified image elements of the animation image. If the animation speed v _d is large, the user tends not to check the details of the displayed image, by taking the configuration described above, without giving inconvenience to the user, and reduce the rendering load, resulting in smooth animation Display can be realized.

In the present embodiment, the adjustment unit 130 changes the character element included in the animation image to the substitute image when the animation speed v _d is high. As a result, it is possible to reduce the drawing load of a font that generally has a high drawing processing load.

In the present embodiment, the adjustment unit 130 changes the image element included in the animation image to the substitute image when the animation speed v _d is high. Thereby, in particular, it is possible to reduce the load of image conversion processing such as transmission and enlargement / reduction of a transparent color of an image displayed in a vector format.

  In addition, this invention is not limited to the said embodiment, Of course, the various change in the range which does not deviate from the summary of this invention is possible.

  For example, in the above-described embodiment, an example in which the operation feature extraction unit 110 determines the user's swipe operation has been described. However, the user touches the operation surface with two fingers and changes the interval between the touching fingers. When an operation to perform this is performed, it may be determined that the operation is a pinch-out / pinch-in operation instructing the enlargement / reduction of the image. In addition, for example, when the user touches the operation surface with two fingers and moves the two touching fingers in the same direction on a concentric circle, the rotation operation is an instruction to rotate the image. It may be configured to discriminate. The display control apparatus 100 has different standards depending on the number of points touched on the operation surface, and when the number of points is two, the distance between the two points or the slope of the straight line connecting the two points From the above, the above operation is determined.

  In the embodiment described above, the display control process has been described by taking the case where the animation image slides at a constant speed as an example, but the movement of the animation image is not limited to the constant speed slide.

For example, when the user touches the operation surface of the operation reception device 200 and performs a so-called flick operation that slides with momentum, the animation of the image displayed on the display device 300 is gradually decelerated (decelerated slide). It may be configured to stop. In this case, after the drawing instruction unit 140 outputs the drawing instruction of the i-th frame in step S401 of the drawing instruction process, the adjustment unit 130 decreases the animation speed v _d at a certain rate, and the reduced animation speed v _d. The display mode of the (i + 1) th frame may be changed according to the value of.

  In addition, for example, when the user performs an enlargement operation for enlarging the display image, the image displayed on the display device 300 is displayed with a constant speed enlargement animation that is enlarged at a constant speed, or is made transparent little by little. You may comprise so that the animation display of the transparent expansion expansion which expands and fades out may be made. Further, the display control processing of the present embodiment may be applied to animation display such as image reduction and rotation.

In the above-described embodiment, it has been described that the image correction method is set in advance in the image correction table 131 and the frame rate is set in advance in the frame rate table 132. However, it is determined dynamically according to the processing load such as the CPU usage rate. You may comprise. For example, the adjustment unit 130 does not adjust the display mode regardless of the animation speed v _d when the CPU usage rate is less than 10%, and when the CPU usage rate exceeds 50%, whichever Also in the display area, the frame rate may be changed to 10 fps. With this configuration, it is possible to perform optimal animation display according to the processing load of the display control apparatus 100.

  Further, in the above-described embodiment, it has been described that the frame rate of the animation image is set for each display area in the frame rate table 132. However, the adjustment unit 130 may select each display area according to the area of the display area. The frame rate may be set. For example, when the area of the display area is less than 10% of the total area of the display image, the frame rate may be set to 40 fps. With this configuration, even when the area of the display area can be changed by a user setting or the like, optimal animation display can be performed according to the changed area of the display area.

Further, the frame rate may be configured to be set according to the animation speed v _d and the total movement amount L _d .

  In the above-described embodiment, it has been described that the adjustment unit 130 performs the adjustment for replacing the character element included in the animation image with the same dummy image regardless of the character type. However, the adjustment unit 130 may be replaced with a different dummy image for each character type. You may comprise. For example, if the character for image correction is a Chinese character, the character color dot ratio is changed to an image of 60%. If the character for image correction is a number or alphabet, the character color dot is changed. The image may be changed to an image having a ratio of 15%. With this configuration, a more natural animation display can be realized.

  In the above-described embodiment, it has been described that the adjustment unit 130 performs the adjustment to replace the image element included in the animation image with the single-color rectangular image. However, the adjustment unit 130 is an image in which the load of the drawing process is reduced as compared with the image before the adjustment. Any other image may be used. For example, the substitute image may be a monochrome circular image or an image in which the resolution of the image element to be substituted is lowered.
