Description

  The present invention relates to a technique for displaying a thumbnail provided for each image data.

  In recent years, electronic still cameras, so-called digital cameras, have been developed and are in widespread use. Image data obtained by a digital camera can be easily managed and viewed by taking it into a personal computer and using dedicated album software. On the other hand, if photo retouching software is used, the brightness and contrast of image data can be easily corrected (processed).

  The album software generally has a function of displaying a list of a plurality of thumbnails (reduced samples of image data) provided for each image data on a screen. Furthermore, a technique has been proposed in which the corrected image of each image data can be confirmed from the display of the thumbnail by performing image processing on each thumbnail displayed on the screen collectively (for example, Patent Document 1) below. According to this configuration, it is possible to greatly shorten the correction confirmation work.

The first and second functions correspond to a photo album function, and the third and fourth functions correspond to a photo retouch function.

  FIG. 2 is an explanatory diagram showing an initial state of the application window WD1 displayed by the computer program Pr. The application window WD1 constitutes a graphical user interface (GUI), and as illustrated, a menu bar FL1, a process menu column FL2, a tool bar FL3, and a work area FL4 are provided. In the processing menu field FL2, four types of buttons BT1, BT2, BT3, and BT4 of [Input], [Correction], [Print], and [Output] are arranged in order from the top to the bottom. By sequentially clicking these buttons BT1 to BT4 with the mouse 24, it is possible to proceed with the operation of inputting, correcting and outputting the photograph image taken by the digital camera 26 on the screen of the display 20. .

  In the initial state of the application window WD1, as shown in FIG. 2, the [Input] button BT1 is selected. At this time, the toolbar FL3 has [Input from File] and [Input from List]. Two types of icons IC1 and IC2 are provided. The processing executed when this [input from list] icon IC2 is clicked is based on the first function and the second function described above. The process executed when the [Correction] button BT2 is clicked is based on the third function described above. The process executed when the [Print] and [Output] buttons BT3 and BT4 are clicked is based on the fourth function described above. In this embodiment, the first function will be described, and the second to fourth functions will not be described because they are not directly related to the present invention.

  FIG. 3 is a flowchart showing a thumbnail display routine for realizing the first function. This thumbnail display routine is started when the [Input from List] icon IC2 is clicked. As shown in the figure, when the process is started, a process for displaying the window WD2 for [input from the list] on the display 20 is executed (step S100).

  FIG. 4 is an explanatory diagram showing a window WD2 for [input from list]. As shown in the drawing, the [input from the list] window WD2 is provided with a toolbar FL11, a file designation area FL12, and a thumbnail display area. The file designation area FL12 is a field for designating the storage location of the image data Dp using “folder” or “film”. This designation follows the input operation of the mouse 24 by the operator. In addition to the hard disk drive 16, the storage location on other recording media such as a CD-ROM can be specified, and the recording medium of the digital camera 26 can also be specified directly.

  A thumbnail display area (hereinafter referred to as “thumbnail display area”) FL13 displays a list of a plurality of image data Dp stored in the folder or film designated in the file designation area FL12 as thumbnails. belongs to. The thumbnail display area FL13 is a so-called pane and corresponds to the “predetermined display area” of the present invention. A pane is one area when one window is divided into several display areas in the GUI.

  In step S110, the folder (or film) is not specified using the file specification area FL12, and the thumbnail display area FL13 is blank. Returning to FIG. 3, the CPU 11 specifies a folder (or film) in response to the operator's instruction in step S120, and in step S130, the plurality of image data Dp stored in the specified file or folder. Are displayed in the thumbnail display area FL13.

  Since the image file obtained by the digital camera 26 is usually an Exif format image file, thumbnail data representing a thumbnail of the image data Dp is attached. In step S130, display is performed using the thumbnail data. The thumbnails displayed in the thumbnail display area FL13 are not limited to the image data obtained by the digital camera 26, and image data in various data formats stored in the folder or film designated in step S120. It becomes a target. For this reason, for the image data to which no thumbnail data is attached, a process of reducing the image data is performed in step S120 to generate a thumbnail, and the thumbnail is displayed.

  In the illustrated example, ten thumbnails are displayed in the thumbnail display area FL13, and up to twelve can be displayed as they are. When there are 13 or more thumbnails, a scroll bar appears on the right side of the thumbnail display area FL13, and all the thumbnails can be displayed in order by scrolling the screen by operating the scroll bar. It has become.

  Specifically, in step S130, a drawing area corresponding to the thumbnail display area FL13 is secured in the RAM 14, and a plurality of thumbnails to be displayed in the thumbnail display area FL13 are drawn (expanded) in order in the drawing area. Thereafter, the contents of this drawing area are transferred to the video memory 15 to display thumbnails in the thumbnail display area FL13. The drawing area secured in the RAM 14 corresponds to the “memory area” of the present invention. This step S130 corresponds to the thumbnail drawing unit 30 and the display control unit 32 (FIG. 1) described above. In step S130, along with the thumbnail drawing, various parts displayed in the thumbnail display area FL13 are also drawn in the drawing area. As the various parts, for example, as shown in FIG. 4, “number” and “file name” character strings C1 and C2 arranged above and below the thumbnail TH, the background BK above and below the thumbnail, and the like.

  When the thumbnail list is displayed in step S130, the CPU 11 next determines whether or not the [correction display] icon IC12 is clicked (step S140). [Correction display] icon IC12 is provided on toolbar FL11 of window WD2 for [input from list], and is operated by an operator when it is desired to perform image processing on thumbnails displayed in a list all at once. Is. If it is determined in step S140 that the [Correction display] icon IC12 is not clicked, the process returns to “Return” to end the thumbnail display routine once.

  On the other hand, if it is determined in step S140 that the [Correction display] icon IC12 is clicked, the filter menu MN is opened (displayed). The filter menu MN is displayed in a pull-down format below the [Correction Display] icon IC12, and displays a list of filter types that give various effects to the image. The filter is for determining image processing (correction processing) to be performed on image data, and various types are prepared in advance.

  FIG. 5 is an explanatory diagram showing an example of the filter menu MN opened from the [Correction display] icon IC12. As shown in the figure, the filter menu MN has five types of filters as options: “monotone”, “tone curve”, “white / black / density”, and “unsharp mask”. The operator performs an operation of clicking on a desired one of these options.

  Returning to FIG. 3, when the filter menu MN is displayed in step S150, the CPU 11 performs a process of inputting the type of the filter by receiving an operation of clicking on the filter menu MN by the operator (step S150). S160). Thereafter, the CPU 11 performs a process of displaying a dialog box for image processing corresponding to the filter input in step S160 (step S170).

  FIG. 6 is an explanatory diagram showing an example of a dialog box DB1 for [Monotone] displayed when the “Monotone” option is clicked in the filter menu MN. As shown in the drawing, the dialog box DB1 is provided with a field FL21 for displaying an original image, a field FL22 for displaying a corrected image, and a field FL23 for an operation system.

  The operation field FL23 is provided with slider bars SB1, SB2, and SB3 for adjusting red (R), green (G), and blue (B), respectively. The operator can specify the color to be monotonated by operating the slider bars SB1 to SB3. That is, a parameter representing the intensity of image processing (that is, the intensity of correction) corresponding to the filter input in step S160 can be designated by the operation field FL23.

  In the original image display field FL21, one of a plurality of thumbnails displayed in the thumbnail display area FL13 is displayed as a representative thumbnail. In this embodiment, the representative thumbnail is defined as the first thumbnail, that is, the thumbnail displayed at the upper left. Even when there are a large number of thumbnails and scrolling is required to display all image data stored in the folder or film designated in the file designation area FL12 as described above, Of the twelve or less thumbnails displayed in the original image display field FL21, the one displayed at the upper left is defined as the representative thumbnail.

  As a modification of this embodiment, the representative thumbnail may be determined to be clicked by the operator from a plurality of thumbnails displayed in the thumbnail display area FL13. In this case, one thumbnail is selected from a plurality of thumbnails displayed in the thumbnail display area FL13 in advance by receiving a click operation by the operator, and thereafter, a [correction display] icon IC12 is selected. Wait for the to be clicked. If the [Correction display] icon IC12 is clicked without selecting a thumbnail, an error may be displayed to prompt the operator to select a representative thumbnail first.

  The CPU 11 executes image processing determined from the type of image processing corresponding to the filter input in step S160 and the parameters specified from the operation field FL23 on the representative thumbnail described above, and the processed thumbnails are processed. The image is displayed in the corrected image display field FL22. As a result, the display image of the corrected image display field FL22 changes in conjunction with the operation of the slider bars SB1 to SB3 of the operation field FL23. When the operator determines that the displayed image has a desired monotone color, that is, an acceptable monotone color, the operator performs an operation of clicking an [execute] button BT11 provided below the slider bar SB3. When the “execute” button BT12 is clicked, the adjustment values of the slider bars SB1 to SB3 at that time are stored in the RAM 32 as [monotone] parameters in steps S180 and S190 of FIG.

  Here, as described above, “monotonization” has been described as an example of the parameters acquired by the processing in steps S160 to S190. However, in other image processing, parameters related to the image processing can be obtained similarly. become. For example, in the “unsharp mask” image processing, the “radius”, “intensity”, and “threshold” parameters of the unsharp mask effect are obtained.

  In subsequent step S200, CPU 11 determines the contents of the drawing area for one pane used for displaying the thumbnail in step S130, the type of image processing corresponding to the filter input in step S160, and the parameters calculated in step S190. Correction processing is performed by image processing determined from the above. The processing in steps S150 to S190 corresponds to the correction information input unit 34 (FIG. 1) described above, and the processing in step S200 corresponds to the display correction unit 36 (FIG. 1) described above. Thereafter, the CPU 11 performs processing for rewriting (redisplaying) the thumbnail display area FL13 by transferring the contents of the drawing area corrected in step S210 to the video memory 15 (step S210). After execution of step S210, the process returns to “Return” to end the thumbnail display routine.

  FIG. 7 is an explanatory diagram showing an example of the [input from the list] window WD2 after the execution of step S210. The illustrated example is after the image processing determined by the [monotone] dialog box DB1 shown in FIG. 6 is performed from the state of the [input from list] window WD2 shown in FIG. . Since color display is not possible in the drawing, it is difficult to understand in the drawing, but the entire display image displayed inside the thumbnail display area FL13 is monotonized as determined by the dialog box DB1. As a result, all the thumbnails displayed in the thumbnail display area FL13 are also monotonized as determined by the dialog box DB1.

  In the filter menu MN shown in FIG. 5, as described above, five types of filters of “monotone”, “tone curve”, “white / black / density”, and “unsharp mask” are prepared in advance. However, there are also choices of “work note 1” and “work note 2”. A “work note” stores a plurality of types of image processing (filters) applied to image data, and is created in accordance with an operation command from an operator. Specifically, the operator clicks the “Create work note” option provided at the bottom of the filter menu MN to display the [Create work note] dialog box DB 2, and the dialog box Work notes are created using DB2.

  FIG. 8 is an explanatory diagram showing an example of the dialog box DB2 for [Create work note]. As shown in the figure, a plurality of filter options are prepared in the filter field FL31, and one of the plurality of filter options is clicked, and then the [Add to end] button BT31 is clicked. Thus, the filter desired by the operator can be transferred to the field FL32 for work notes. A dialog box DB1 for image processing corresponding to FIG. 6 can be displayed by selecting one of the filters transferred to the field FL32 for work notes and clicking the [Parameter Setting] button BT32. A parameter indicating the intensity of image processing can be set from this dialog box DB1. Thereafter, by clicking the [Register Work Note] button BT33, it is possible to register a work consisting of a plurality of filters registered in the work note field FL32 as a work note. At this time, the work note can be given a name, and this name is added to the filter menu MN.

  Therefore, the operator can store an efficient image processing operation performed on the thumbnail in the personal computer 10 and can use it anytime when performing a work for creating another image.

C. According to the present embodiment configured as described above, thumbnails displayed in the thumbnail display area FL13 provided in the [input from the list] window WD2 shown in FIG. The entire display area FL13 can be corrected collectively. For example, when the image of the original image and the image after correction are greatly different as in the case of monotonization, even when the original image is viewed as it is, the image when it becomes the final work is difficult to understand. On the other hand, in the present embodiment, the corrected image of each image data can be grasped from the list of corrected thumbnails, so that one image that is truly suitable for the work can be easily selected from a plurality of image data. Can do.

  Furthermore, in this embodiment, each thumbnail can be corrected by performing image processing only once on the image in the thumbnail display area FL13, which is a pane. Therefore, the processing speed is fast, and it takes time to redisplay the thumbnail. There is no such thing. Therefore, workability can be sufficiently enhanced.

D. Other embodiments:
The present invention is not limited to the above-described examples and embodiments, and can be implemented in various modes without departing from the gist of the present invention. For example, the following modifications are possible.

(1) In the above-described embodiment, a drawing area corresponding to the “memory area” of the present invention is secured in the RAM 14, and a thumbnail is drawn on this drawing area and image processing is performed, and then the contents of the drawing area However, instead of this, the following configuration may be used without using a drawing area. First, a process of drawing a thumbnail in the thumbnail display area FL13 is performed on the video memory 15, and then drawing data representing the window WD2 developed in the video memory 15 is transferred (copied) to the RAM. Then, the image processing is performed on the portion corresponding to the thumbnail display area FL13 in the drawing data transferred to the RAM 14, and then the corrected drawing data is output to the video memory 15. . That is, after instructing the operating system (hereinafter referred to as “OS”) to display thumbnails in the thumbnail display area FL13, the contents of the video memory 15 are read out, and the part corresponding to the thumbnail display area FL13 in the contents The image data is subjected to image processing, and the processed drawing data is returned to the video memory 15. Not all video boards that can constitute the video memory 15 can read data from the application side, but some video boards can read data depending on the model of the video board. This modification can be realized by using this type of video board. In this modification, the video memory 15 corresponds to the “memory area” of the present invention.

  Further, the drawing data read from the video memory 15 may not be the entire window as described above, but may be for one pane, that is, the thumbnail display area FL13. According to this configuration, it is only necessary to perform image processing on the entire read drawing data, and the processing configuration becomes easy.

  Furthermore, as another embodiment in which the drawing area is not used, a process of drawing a thumbnail in the thumbnail display area FL13 is performed on the video memory 15, and then the thumbnail display area FL13 in the video memory 15 is handled. It is also possible to adopt a configuration in which drawing data is corrected (correction based on the image processing). In other words, the application program may directly correct the drawing data corresponding to the thumbnail display area FL13 in the video memory 15.

(2) In the above embodiment, since the entire image drawn in the thumbnail display area FL13 is corrected in a lump, the thumbnail portion as well as the thumbnail display area FL13 as shown in FIG. The parts other than the thumbnail TH, that is, the character strings C1 and C2 of the “number” and “file name”, the background BK, and the like are also monotonized. Therefore, in this modified example, when thumbnails are displayed in the thumbnail display area FL13, mask data for hiding parts other than the thumbnails is created, and image processing is performed after the drawing area of the RAM 14 is covered with the mask data. It is set as the structure to give.

  FIG. 9 is an explanatory diagram showing mask data MD corresponding to the thumbnail display area FL13 illustrated in FIG. As shown in the figure, the mask data MD represents the same size as the thumbnail display area FL13, and the bitmap format in which the area XTH where the thumbnail is drawn is white and the area other than the area XTH is black. Image data. Specifically, first, the contents of the drawing area secured in the RAM 14 are temporarily copied to another area, and then the mask data MD is synthesized with the contents of the drawing area. Next, image processing is performed on the contents of the drawing area combined with the mask data MD. Thereafter, the data copied to another area is combined with the inverted data obtained by inverting the mask data MD, thereby creating drawing data representing a portion other than the thumbnail in the thumbnail display area FL13. Next, the drawing data is overwritten on the contents of the drawing area. Thereafter, by outputting the contents of the drawing area to the video memory 15, the thumbnail display area FL13 represented in the drawing area is displayed. According to this modification, only the portion of the thumbnail TH in the thumbnail display area FL13 is subjected to the correction process, and the portions other than the thumbnail TH, that is, the character strings C1, C2 of “number” and “file name”, Correction processing is not performed for the background BK portion and the like.

(3) In the description of the above-described embodiment, the image processing performed on the target image data by the above-described third function that is a photo retouch function is not particularly mentioned. This is because the photo album function and the photo retouch function are independent of each other. In the above embodiment, the operator first considers the image processing that the user wants to perform as photo retouching, sets the type and parameter for the image processing using the user interface shown in FIGS. It was configured to set similar types and parameters anew. On the other hand, as a modification, the image processing type and parameters set by the user interface shown in FIGS. 5 and 6 may be taken over by the photo retouch function. That is, the image processing type and parameters set by the user interface shown in FIGS. 5 and 6 are stored in the RAM 14, and the image processing determined from the stored image processing type and parameters is performed in the photo retouch function. The configuration is applied to data. According to this structure, workability | operativity can fully be improved also as an image correction apparatus.

(4) In the above-described embodiment, the image processing is determined from the type of correction processing and the parameter indicating the correction strength. That is, the “correction information” of the present invention is configured by the type and parameters of the correction process. Instead of this, as a modification, the correction information may be configured by only the type of correction processing. The intensity of correction in this case may be a constant value determined for each type of correction processing. The “correction information” may have any configuration as long as it can determine image processing.

(5) In the above-described embodiment, the “predetermined display area” is configured as one pane when one window is divided into a plurality of panes, but is not necessarily limited to the pane, and the entire window is predetermined. The display area may be any area as long as it is an area formed on the screen of the display device.

(6) In the above embodiment, the image data is a color photographic image. However, the present invention is not limited to this, and can also be applied to image data such as symbols. Further, the image is not limited to a color image, and may be a black and white image.
