Description

  The present invention relates to a reduced image list display system and method, and a program for controlling the system.

When original image data representing a large number of original images is recorded on a hard disk or the like, reduced images may be displayed in a list so that it can be seen at a glance what original images exist (Patent Documents 1 and 2).
JP 2003-46911 A JP 2004-120605 A

  However, the reduced images displayed in the list are simply reduced images of the original images. For this reason, the reduced image includes a portion that is not very important for confirming the image. Since the reduced image is small, an important part may not be confirmed.

  An object of this invention is to make it possible to confirm important parts.

  The reduced image list display system according to the present invention reads original image data recorded on a digital recording medium, and cuts out the original image represented by the read original image data so as to be a display image having a predetermined shape. Cutout means, a display image data storage device (which may be a digital recording medium) for storing display image data representing a display image cut out by the cutout means, the cutout processing and the storage processing are recorded on the digital recording medium In response to the input of the list display command from the control means for controlling the cutout means and the display image data storage device, the list display command input means, and the list display command input means so as to be repeated for the original image data being displayed. Display image data stored in the display image data storage device. Accordingly, there is provided reduction means for reducing the display image represented, and first display control means for controlling the display device so as to display the reduced display image reduced by the reduction means on the display screen. It is characterized by being.

  The present invention also provides a method suitable for the reduced image list display system. That is, in this method, the original image data recorded on the digital recording medium is read, and the original image represented by the read original image data is cut out and cut out so as to be a display image having a predetermined shape. Display image data representing a display image is stored, the cutout process and the storage process are repeated for the original image data recorded on the digital recording medium, and a list display instruction is given, The display image represented by the stored display image data is reduced, and the reduced reduced display image is displayed on the display screen.

  The present invention also provides a program for controlling the reduced image list display system.

  According to the present invention, a display image having a predetermined shape is cut out from the original image. Display image data representing the clipped display image is stored. When a list display command is given, a reduced display image is generated from the display image, and the reduced display image is displayed on the display screen.

  Since the reduced display image is generated from the display image smaller than the original image, the size of the reduced display image becomes larger than when the original image is reduced at the same reduction ratio. If the reduction ratio is the same, the image can be easily confirmed.

  The cutout means cuts out the display image having a shape different from the shape of the original image or a square shape, for example. If it is square, it will be easy to see whether the original image is portrait or landscape.

  The cutout unit may cut out the display image so that the center coincides with the center of the original image. Since the important part of the image is often in the center, it is possible to prevent the important part from being removed from the display image.

  The cutout unit may include a first determination unit that determines whether at least one target image of a face image and a human image is included in the original image. In this case, when it is determined that the target image is included by the first determination unit, the display image including the target image is cut out.

  It is preferable that the image processing apparatus further includes a rotating unit that rotates the display image so that the target image included in the display image is in an upright state.

  The cutout unit may further include a second determination unit that determines whether or not a non-image area in which no image exists is included when the display image is cut out to have the predetermined shape. In this case, a display image that is an image in the original image and does not include the non-image area is cut out in response to the determination by the second determination means that the non-image area is included. Let's go.

  FIG. 1 shows an embodiment of the present invention and is a block diagram showing an electrical configuration of a list image display system.

  The list image display system is provided with an input device 9 such as a keyboard and a mouse, and an operation signal output from the input device 9 is input to the CPU 1. The CPU 1 reads the program, data, etc. recorded on the CD 6, reads the data, etc., recorded on the CD drive 5 and the hard disk 8 for writing the data, etc. on the CD 6, and writes the data, etc., to the hard disk 8. HD drive 7 is provided. When the CD 6 storing a program for performing an operation to be described later is read by the CD drive 5, the program of the list image display system is installed.

  The list image display system includes a memory 4 that temporarily stores data and the like, a display device 2 that displays images and the like, and a printer 3 that prints images and the like.

  FIG. 2 is a flowchart showing a display image generation processing procedure.

  The display image generation processing according to this embodiment is to extract a display image including an important part of the original image. When a person image or a face image is included in the original image, the person image or the face image is considered important, and a display image including the person image or the face image is generated. If neither the human image nor the face image is included in the original image, the image in the area centered on the center of the original image is considered important and a display image is generated.

  It is assumed that original image data representing the original image is recorded on the hard disk 8.

  Original image data representing the original image is read from the hard disk 8 (step 11) and temporarily stored in the memory 4. It is confirmed whether or not a person image is included in the original image (step 12). Whether or not a person image is included can be determined by detecting the face image and then changing the size and color of the area (hair, neck, jacket, etc.) that is continuous with the face image.

  3A to 3D are examples of images.

  For example, assume that the original image is an image I11 shown in FIG. Since the original image I11 includes the person image 61 (YES in step 12), erecting processing is performed if necessary (step 13). The erecting process is a process in which when an image is displayed, the direction is the same as the direction in which the image was captured. For example, when the camera is placed vertically during shooting, the obtained image is displayed horizontally, so that it is displayed vertically as during shooting. Details of this erecting process will be described later.

  When the erecting process is completed, a display image area is set around the person image (step 14).

  Referring to FIG. 3B, when a person image 60 is detected in the original image, a display image area A11 having a predetermined size around the center of the person image 60 is set.

  It is confirmed whether or not there is a portion where no image exists in the set display image area (step 15). If there is a portion where no image exists (YES in step 15), the set display image area is shifted so that there is no portion where no image exists (step 16).

  In FIG. 3B, there is a portion 70 having no image in the set display image area A11. Therefore, as shown in FIG. 3C, the display image area A11 is shifted so that there is no portion where no image exists (in FIG. 3C, it is shifted to the left as compared with FIG. 3B). )

  An image existing in the set display image area is cut out as a display image (step 17). The image data representing the display image thus obtained is recorded on the hard disk 8 (step 18).

  In FIG. 3C, an image in the display image area A11 is cut out from the original image I11, whereby a display image I12 is obtained as shown in FIG.

  If there is no portion without image in the set display image area (NO in step 15), the shift process of the display image area is skipped.

  If a person image is not included in the original image (NO in step 12), the display image area is set so that the center of the original image is the center (step 19).

  In the embodiment described above, the process differs depending on whether a person image is included in the original image, but the process may be different depending on whether a face image is included.

  4A to 4C are examples of images including a plurality of person images.

  (A) is an example of an original image, (B) shows a display image area, and (C) is an example of a clipped image.

  As shown in (A), the original image I11 includes a plurality of person images 61. When a plurality of person images are included, the display image area A21 is set so as to include the plurality of person images 61 as shown in FIG. An image in the display image area A21 is cut out, and a cutout image I22 is obtained as shown in FIG.

  5A to 5C are examples of images that do not include a human image.

  Referring to (A), the original image I31 does not include a person image. In this case, as shown in (B), the display image area A31 is set so that the center of the original image I31 is the center. The set display image area A31 is cut out, and a cutout image I32 is obtained as shown in FIG.

  FIG. 6 is a flowchart showing the upright processing procedure (the processing procedure of step 13 in FIG. 2).

  An eye image and a mouth image are detected from the detected person image (step 21). A face image will be detected from a person image with reference to color change and facial appearance, and an eye image and a mouth image will be detected from the face image with reference to the positional relationship.

  If the eye image is placed vertically (YES in step 22), that is, if the second eye image is aligned vertically, the original image is considered to have been vertically oriented when the image was taken. . For this purpose, the original image is rotated 90 degrees clockwise (step 23). If the eye image is not arranged vertically (NO in step 22), the process of step 23 is skipped.

  Subsequently, it is confirmed whether or not the mouth image is arranged above the eye image (step 24). If the mouth image is placed in the eye image information (YES in step 24), it is considered that the camera was turned upside down when the original image was taken. For this purpose, the original image is rotated 180 degrees in order to make the top and bottom correct positions (step 25). If the mouth image is not placed on the eye image (NO in step 24), the original image is displayed at the correct position, so the process of step 25 is skipped.

  In any case, an original image in the same direction as that at the time of shooting is obtained.

  FIG. 7 and FIG. 8 are flowcharts showing the processing procedure of the display reduced image list display. FIG. 9 shows an area where the reduced images for display are displayed in a list.

  When a list display command is input from the input device 9, display image data representing a display image recorded in the hard disk 8 is read (step 32). Then, the display image is reduced at a reduction ratio (which may be predetermined in advance) determined by the area where the reduced image is to be displayed and the number of frames of the reduced image displayed in the area. (Step 33). When reduced display images are obtained for a plurality of display images, a list is displayed as shown in FIG. 9 (step 34).

  Referring to FIG. 9, reduced display images 51 generated in region 50 (which may be the display screen itself) are displayed side by side. Since the important part is extracted from the reduced display image 51, the important part can be confirmed even if it is a small image.

  Below the area 50, areas 52, 53 and 54 for specifying functions are provided. The area 52 is an area clicked by the user when displaying an image of one frame over the area 50 or the entire display screen of the display device 2. An area 53 is an area clicked by the user when printing an image of one frame. The area 54 is an area clicked by the user when performing a slide show.

  A function is selected when one of the areas 52, 53 and 54 is clicked by the user (step 35).

  When the full-screen display area 52 is clicked, the display reduced image for one frame and the type (original image or display image) are specified from the reduced display image 51 (step 36). ). For example, when the full screen display area 52 is clicked and the display reduced image 51 is clicked, a new window for selecting whether the original image or the display image is displayed is displayed, and the type can be selected using the window.

  When the original image is selected as the type of full screen display, the original image corresponding to the selected display reduced image 51 is displayed on the entire screen over the region 50 or the entire display screen (step 37). When the display image is selected, the display image is displayed in full screen corresponding to the selected display reduced image 51 (step 38).

  When the print area 53 is clicked, designation of a reduced image for display and its type are performed (step 39). When the original image is selected as the type of image to be printed, the original image corresponding to the selected display reduced image 51 is printed by the printer 3 (step 40). When a display image is selected as the type of image to be printed, a display image corresponding to the selected reduced display image 51 is printed by the printer 3 (step 41).

  When the slide show area 54 is clicked, the type of image to be slide show is selected (step 42). When the original image is selected, a slide show of the original image is started (step 43), and when the display image is selected, the slide show of the display image is started (step 44).

  In the above embodiment, the display image is a square, but other shapes may be used. The shape may be different from that of the original image.
