Description

  The present invention relates to a technique for creating one piece of print data from moving image data.

  Conventionally, various techniques for creating one still image from moving image data have been developed. For example, according to Patent Document 1, each data of a print target image in a moving image and a reference image one second before and one second after the print target image is taken into a frame memory in frame units. The matching processing unit performs local matching processing on the print target image data and the reference image data, and divides the print target image into a still area and a moving area. The still area weighted average unit weights and averages pixel data in the same position of the print target image and the reference image with respect to the still area. The moving region smoothing processing unit performs smoothing processing on the moving region using the image data of the print target image. The still image and moving region image data subjected to these processes are combined by the image combining unit.

According to Patent Document 2, the detection angle of the angle detection unit is associated with each shooting cut and stored in the shooting angle storage unit. At the time of printing, panoramic shot image data including a plurality of shooting cuts is stored in the shooting angle storage unit. When outputting data of a plurality of shooting cuts identified as panoramic shooting specified from the shooting angle information, the shooting data reading means configures and outputs the composition processing of the joining shot portions of adjacent shooting cuts.

  Hereinafter, the flow of the printing operation of the printer 300 according to the present invention will be described with reference to the flowchart of FIG.

  First, in S <b> 1, the CPU 31 reads moving image data and attached information from the memory card 17 inserted into the media insertion slot 33 into the memory 34.

  In S <b> 2, the CPU 31 determines an arrangement route of the frame image within the print range based on the movement path of the camera optical axis included in the attached information. As an example, this arrangement path appropriately enlarges / reduces the movement path of the camera optical axis so that the start point and the end point of the movement path of the camera optical axis are arranged at the start point P0 and the end point P1 of the arrangement path existing at a predetermined position in the print range. Can be determined.

  FIG. 5 shows an example of the arrangement route in the print range. As shown in this figure, the arrangement route is arranged so as to pass through the inside of the outer peripheral edge X of the print range. However, the method of determining the arrangement path of the frame image is arbitrary, and may be determined based on the locus drawn by the light spot of the specific subject image, or may be arbitrarily specified by the user by operating the touch panel monitor 39. Also good.

  In S3, a frame image to be arranged along the arrangement route determined in S2 is selected, and the selected frame image is arranged along the arrangement route. The method of selecting the image to be arranged is arbitrary. For example, it may be arranged for each frame image separated by a predetermined time. Alternatively, as shown in FIG. 6, among the plurality of frame images F2 to F4 photographed at the photographing time close to the photographing time of a certain frame image F1, a frame image F4 having the smallest overlapping area with F1 may be arranged.

  In S4, a plurality of frame images arranged along the arrangement route are combined into one print image (see FIG. 7).

  In S5, the print engine 35 drives a printer (not shown) according to the combined print image, and prints the print image.

  In the print image synthesized in S4, when the blank in the print range exceeds a predetermined amount (for example, when the ratio of the blank to the print range exceeds 50%), a predetermined background color or background image, or a frame in advance A blank portion may be filled by arranging and synthesizing a still image associated with an image in the vicinity of the frame. The association between the frame image and the still image can be performed by the camera 100. For example, as shown in Japanese Patent Laid-Open No. 2003-158653 by the present applicant, any one of the still images continuously shot during the moving image shooting mode is used. , Can be associated with the video that was shot. Information indicating the relationship between the moving image and the still image is also included in the attached information. By filling in the blank part as much as possible, the appearance of the printed image can be further improved.

  Further, the size of each selected frame image may be changed according to the zoom magnification of the attached information corresponding to each selected frame image. FIG. 8 shows a state in which the size of each frame image is enlarged or reduced so as to be inversely proportional to the zoom magnification. In this way, a frame shot at a low magnification, that is, a frame on the wide-angle side can be enlarged, and a frame shot at a high magnification, that is, a frame on the close side can be reduced. You can get a good-looking print.

  Alternatively, the inclination of each selected frame image may be corrected according to the inclination movement information corresponding to each selected frame image. FIG. 9 shows a state in which the inclination of each frame image is corrected in accordance with the inclination movement information. In this way, frame images shot at an inclination can be combined with the inclination corrected, and a good-looking print can be obtained.

  In any case, according to the present invention, a plurality of frame images constituting a moving image can be unified into a single print image without a sense of incongruity, and a print with a wide visual field and good appearance can be obtained.
