Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the drawings. However, the constituent elements described in this embodiment are merely examples, and are not intended to limit the scope of the present invention only to them.
(First embodiment)
Hereinafter, one embodiment of the present invention will be described in detail according to the attached screen. The display control apparatus in this embodiment arranges image data in a two-dimensional area and creates a digital scrapbook. A scrapbook is a notebook for placing an arbitrary photo at an arbitrary coordinate. The digital scrapbook is a realization of this scrapbook on a computer device, and an operator can arrange image data at arbitrary coordinates and lay out freely.

  The display control apparatus according to the present embodiment displays only the image data necessary for determining the placement destination layer in response to the designation of the placement destination coordinates of the image data. FIG. 1 shows an example of a layer designation screen (details of the layer designation screen will be described later). The operator can arrange the image data in a desired layer by confirming the image data displayed in the layer and designating the arrangement destination layer.

A configuration example of the display control apparatus in the present embodiment will be described with reference to FIG.
In FIG. 2, reference numeral 201 denotes a control unit that controls the entire computer apparatus 200 that realizes the display control apparatus, and is, for example, a central processing unit (CPU). A read only memory (ROM) 202 stores programs and parameters that do not need to be changed.

  A random access memory (RAM) 203 temporarily stores programs and data supplied from an external device or the like. Reference numeral 204 denotes an external storage device including a hard disk or memory card fixedly installed on the computer apparatus 200, a flexible disk (FD) removable from the computer apparatus 200, an optical disk such as a CD, a magnetic or optical card, and an IC card. It is.

  Reference numeral 205 denotes an interface with an input device 209 such as a pointing device 209a or a keyboard 209b that receives user operations and inputs data. Reference numeral 206 denotes an interface with the display 210 for displaying data held by the computer apparatus 200 and supplied data.

  Reference numeral 207 denotes a network interface for connecting to a network line 211 such as the Internet. Reference numeral 208 denotes an image input interface that receives input of image data to be processed from an image input device 212 such as an imaging apparatus. A system bus 213 connects the units of the control unit 201 to the image input interface 208 so that they can communicate with each other.

In the display control apparatus according to the present embodiment, an operator can place an image at a desired coordinate. The image data layout screen at this time will be described with reference to FIGS.
In FIG. 3, the control unit 201 displays a layout area 101 on the display 210 for the operator to lay out image data.

  Image data 102, 103, 104, 301, and 302 are image data arranged in the layout area 101. As shown in the figure, the image data 102, 103, and 104 are formed as one lump with overlapping images. The control unit 201 manages this cluster as a block. Similarly, the image data 301 and 302 are managed as one block. A block is a series of blocks formed by overlapping images. In FIG. 3, there are three blocks.

  In FIG. 4, the operator can operate the input device 209 to add image data 105 to be arranged from the image data standby area (not shown) to the layout area 101. The control unit 201 displays the new image data 105 in the layout area 101 in accordance with the operator's operation. The operator can place the image data 105 at arbitrary coordinates by operating the input device 209.

  When the image data 105 is arranged at the coordinates shown in FIG. 4 by the operation of the operator, the control unit 201 displays a layer designation screen. The layer designation screen is a screen for selecting an image data arrangement destination layer. Details of the layer designation screen will be described with reference to FIG.

  The control unit 201 displays the layout area 101 including the arranged image data 102, 103, and 104 as a layer in which the vertical relationship of overlap can be visually recognized. Further, the control unit 201 displays a plurality of layer designation icons 106 for designating the arrangement destination layer of the image data 105. When the operator operates the input device 209 to select one of the layer designation icons 106, the control unit 201 arranges the image data 105 in the corresponding layer and displays the result on the layer designation screen.

  The operator confirms the arrangement result, and if the desired result, the selected layer designation icon 106 is selected again. As a result, the control unit 201 determines the placement destination layer and hides the layer designation screen. Further, the control unit 201 updates the display content of the image data layout screen and displays the image data 105 on the layer selected by the operator. In the layer designation screen, even after the operator selects the layer designation icon 106, the operator can reselect a different layer designation icon before confirmation.

  Further, the control unit 201 displays a viewpoint change icon 107 for changing the viewpoint on the layer designation screen. The operator can change the viewpoint of the layout area 101 by operating the viewpoint change icon 107 up, down, left and right with the input device 209. When the viewpoint of the layout area 101 is changed by an operator's operation, the control unit 201 updates the display content of the layer designation screen, for example, as shown in FIG. Thereby, the operator can confirm the layer designation screen from an arbitrary viewpoint and can select the arrangement destination layer of the image data 105.

  As shown in FIG. 1, the control unit 201 displays only images belonging to the block in which the image data 105 is arranged on the layer designation screen. Selection of display target data is performed based on object information and layer information. Details of the object information and the layer information will be described with reference to FIGS.

  The coordinates of the laid out image data and the information of the block to which it belongs are stored and managed in the object information shown in FIG. Each image data always belongs to one block and does not belong to a plurality of blocks. Image data that does not overlap with other image data belongs to a block consisting only of the image data. Also, the layer information shown in FIG. 7 stores and manages the layer order of the image data group belonging to each block.

The flow of processing for displaying the layer designation screen when the image data 105 is arranged at the coordinates shown in FIG. 4 by the operation of the operator will be described with reference to the flowchart of FIG.
When the coordinates of the image data 105 are designated by the operation of the operator and the placement destination coordinates are determined, the control unit 201 acquires the placement destination coordinates in S801. In step S <b> 802, the control unit 201 performs overlap detection processing that detects an overlap object of the image data 105 based on the acquired placement destination coordinates. The control unit 201 refers to the object information and compares the coordinates of the image data 105 with the coordinates of the arranged image. Based on the detection result, the control unit 201 detects the image data 102, 103, and 104 as overlapping objects.

  Next, in step S803, the control unit 201 performs block detection processing for acquiring a block to which the overlapping object belongs. This is performed for all overlapping objects detected in S802. As a result, the control unit 201 acquires only Block A as a block to which the overlapping object belongs.

  In step S <b> 804, the control unit 201 performs object extraction processing for acquiring other image data belonging to the block and the layer information based on the layer information. As a result, it can be seen that the layer order of the image data of Block A is the image data 102, 103, and 104 in order from the bottom. Next, in step S805, the control unit 201 acquires the coordinates of each image data acquired from the layer information from the object information.

Next, in step S806, the control unit 201 performs layer display processing for displaying a layer designation screen in accordance with the layer order and coordinates of the image data acquired in steps S804 and S805.
Through the above processing, the control unit 201 can display only the image data necessary for layer designation on the layer designation screen in the correct coordinates and the overlapping order.

Next, a processing flow when the arrangement destination layer of the image data 105 is determined by the operation of the operator will be described with reference to the flowchart of FIG.
When the arrangement destination layer of the image data is determined, the control unit 201 acquires the position of the arrangement destination layer of the image data 105 in S901. As shown in FIG. 1, if the operator places the image data 105 on a layer further above the image data 104, the control unit 201 acquires this position.

In step S <b> 902, the control unit 201 adds the coordinates of the image data 105 and the block information to the object information. In step S903, the control unit 201 adds the image data 105 to the layer information. Specifically, the image data 105 is added to the block A layer information. Since the layer information is stored in order from the image data that overlaps the layer information, the position where the information of the image data 105 is added is the position next to 104.
Through the above processing, the control unit 201 can update the object information and the layer information of the image data.

  8 and 9, the flow of processing when new image data is added to the image data layout screen has been described. Next, the flow of processing for changing the coordinates of image data already arranged on the image data layout screen will be described with reference to the flowchart of FIG.

  When the coordinates of the arranged image data are changed by the operator's operation on the image data layout screen, in step S1001, the control unit 201 refers to the object information and acquires information on the block to which the target image data belonged before the coordinate movement. To do.

  Next, in step S1002, the control unit 201 acquires new arrangement coordinates of the target image data. In step S <b> 1003, the control unit 201 detects an overlapping object at a new arrangement coordinate. The overlapping object detection process is the same as the process described with reference to FIG. In step S <b> 1004, the control unit 201 acquires information on a block to which the target image data newly belongs. This acquisition process is also the same as the process described with reference to FIG.

  Next, in S1005, the control unit 201 performs block change determination processing for determining whether or not the block to which the block belongs has been changed based on the block information before and after the coordinate movement acquired in S1001 and S1004. If the result of this determination processing is that there is no change in the block to which it belongs, in the next S1007, the control unit 201 updates the display coordinates on the image data layout screen and ends the processing.

On the other hand, when there is a change in the block to which it belongs, in step S1006, the control unit 201 performs layer display processing for displaying the object belonging to the coordinate movement destination block as a layer. This layer display processing is the same as the processing described in S804 to S806 in FIG.
With the above processing, the display control apparatus according to the present embodiment can limit the re-designation of the layer when changing the coordinates of the arranged image data only when the block to which the target image data belongs is changed.

  Subsequently, update processing of the object information and the layer information when the coordinates of the arranged image data are changed will be described. When the coordinates of the arranged image are changed by the operation of the operator, if there is no change in the block to which the target image data belongs, only the coordinates of the object information are updated, and the layer information is not updated.

  On the other hand, when there is a change in the block to which it belongs, the object information and the layer information are updated. This is the case when the target image data is moved to a block different from the block to which the target image data belonged. This is also the case when the operator changes the coordinates of the target image data so that it does not overlap any other image. The processing flow at this time will be described with reference to the flowchart of FIG.

  In step S1101, the control unit 201 determines whether the target image data has been moved to a different block from that before the coordinate movement. If there is a block movement, the control unit 201 advances the process to S1102, and if not, advances the process to S1103.

  In step S1102, the control unit 201 updates the object information and layer information of the target image data. More specifically, the coordinates and blocks of the object information are updated. Further, for the layer information, the target image data information is deleted from the layer order of the block before the movement, and the information of the target image data is added in the layer order of the block after the movement. In step S1103, the control unit 201 updates the object information of the target image data. More specifically, the coordinates and blocks of the object information are updated.

  Next, in step S1104, the control unit 201 detects whether or not the number of blocks has changed due to the coordinate change of the arranged image data. This is calculated based on the coordinates of the object information of all image data. Even when the control unit 201 determines in step S1101 that the target image data has not been moved to a different block, there is a possibility that the block has been divided due to a change in the coordinates of the target image data. In this case, despite the fact that the number of blocks has actually increased, the information on the block of object information has not been updated.

In S1104, in order to detect this, the control unit 201 detects a change in the number of blocks based on the coordinates of the object information. As a result, if the number of blocks varies, the control unit 201 updates the object information block and layer information of each image data in S1105. If there is no change in the number of blocks, the control unit 201 ends the process.
Through the above processing, the control unit 201 updates the object information and the layer information when the coordinates of the arranged image data are changed.

  Next, a case where blocks are combined when image data is added will be described. For example, as shown in FIG. 12, the operator places new image data 1201 at coordinates that overlap both of the already placed image data 102 and 301. A block including the image data 102 and a block including the image data 301 are combined into one group by the new image data 1201. At this time, the control unit 201 displays a layer designation screen according to the processing flow described with reference to FIG. The displayed layer designation screen will be described with reference to FIGS. 13 and 14.

  When the image data is arranged so as to overlap a plurality of blocks by the operation of the operator and the blocks are combined, the control unit 201 displays a layer designation screen shown in FIG. On this layer designation screen, as indicated by 1301 and 1302, image data is displayed in layers for each block before combination. Thereby, the operator can select the layer which arrange | positions image data for every block before a coupling | bonding.

  For example, if the operator selects the layer designation icons 1303 and 1304, the layer designation screen is updated to the contents shown in FIG. FIG. 14 shows that the layer designation icons 1303 and 1304 are selected to set the vertical relationship of blocks before combining.

Further, target image data 1201 is arranged and displayed on the designated layer. The operator confirms this arrangement result, and if the desired result, the selected layer designation icons 1303 and 1304 are selected again. As a result, the control unit 201 determines the arrangement destination layer, updates the object information and the layer information based on the contents, and combines the two blocks. The flow of the display content update processing and the management information update processing at this time is the same as the content described with reference to FIGS.
With the above processing, when blocks are combined when image data is added, the operator can designate a placement destination layer for each block to be combined.

  According to the embodiment described above, when an operator arranges image data, the image data can be arranged in a desired layer. In addition, according to the present embodiment, it is possible to recognize a block by overlapping image data, and to change a layer only with a block related to image data operated by an operator. Furthermore, according to the present embodiment, when image data arranged by an operator straddles a plurality of blocks, the blocks can be combined to integrate the layer order.

  In the present embodiment, the case where two blocks are overlapped has been described, but the present invention is similarly applied to a case where three or more blocks overlap. In this embodiment, the object to be arranged is image data. However, any object other than image data may be used as long as the object has coordinate information. For example, the present invention is similarly applied to a text object or a graphic object in a vector format.

  Although the present invention has been described in detail based on preferred embodiments thereof, the present invention is not limited to these specific embodiments, and various forms within the scope of the present invention are also included in the present invention. included. A part of the above-described embodiments may be appropriately combined.
