- Patent Document 1 discloses a technique for performing appropriate panoramic shooting by shooting a previous shot image that constitutes a panoramic image and a next shot image adjacent to each other. Specifically, when the camera disclosed in Patent Document 1 first captures the previous image, the position of the captured frame in the shape of a rectangular frame, which is the imaging range of the previous image, is determined based on the 3-axis acceleration sensor. Based on the detection result, the absolute value is stored. After that, when the next image is taken, the camera frame and the photographing frame indicating the photographing range of the image to be photographed at the same time based on the acceleration detection result by the three-axis acceleration sensor are simultaneously captured by the camera. Displayed on the monitor device. As a result, the photographer can detect the difference in position between the captured frame and the captured frame. Can be recognized, and appropriate continuous images can be taken.

This makes panoramic photography even easier.
- the imaging device 40 of the second embodiment may be incorporated in the portable information processing terminal 50 as shown in FIG.
- the portable information processing terminal 50 can obtain the same effect as described above by assembling the imaging device 40. That is, the portable information processing terminal 50 can prevent the monitor display figure that supports the “norama shooting” from obstructing the shooting of the photographer, and can obtain the effect that the panorama shooting is further facilitated.
- the present invention is not limited to the first and second embodiments, and various embodiments can be adopted. That is, in the first embodiment, the reference line set based on the reference photographed image (first photographed image (previously photographed image)) is the center line 21a of the reference photographed image.
- the reference line may be a line set within an area including the outer periphery of the reference photographed image, and deviated from the center line 61 of the reference photographed image 60 as shown in FIG.
- the line 62 may be used.
- the reference marks are the center marks 22a and 22b.
- the center mark is not always displayed as the reference mark depending on the reference line.
- the shooting range (the orientation of the camera unit 11) is the same as when the reference shot image (first shot image) is shot.
- the reference mark is displayed at a position on the reference line or the virtual extension line.
- the monitor unit 1 2 has the monitor unit 1 2 as shown in FIG.
- Reference marks 65 a and 65 b deviating from the center line 64 are fixedly displayed.
- the reference marks 65a and 65b are positioned so as to overlap the reference line 62 in the monitor unit 12 when the preview image of the monitor unit 12 projects the same shooting range as the reference shot image 60. It is displayed.
- the reference marks 65a ′ and 65b ′ as shown by the dotted lines in FIG. 14 may be displayed outside the monitor unit 12.
- the reference marks 65a ′ and 65b ′ are displayed at positions overlapping the virtual extension line 62 ′ of the reference line 62 when the preview image of the monitor unit 12 projects the same shooting range as the reference shot image 60. ing.
- the reference lines 21a and 46 are displayed in a form in which both ends thereof reach the outer periphery of the monitor unit 12 (screen 45 of the monitor means 41).
- both ends of the reference line 66 may not reach the outer periphery of the screen 67.
- the reference line may be divided into a plurality of lines.
- the reference line in each of the first and second embodiments is a solid line, the reference line may be a line other than a solid line such as a dotted line or a one-dot chain line.
- the form of the reference line is not limited to the form shown in each of the first and second embodiments, and can take an appropriate form in consideration of, for example, what can be clearly indicated. Even if the form of the reference line is other than the forms shown in the first and second embodiments, the same effects as those obtained from the first and second embodiments can be obtained.
- the shape of the reference mark (center marks 22a, 22b) is a triangle.
- the reference mark may have a shape other than the triangular shape, and is not limited to the triangular shape.
- the present invention has been described with reference to the embodiments, the present invention is not limited to the above embodiments. Various changes that can be understood by those skilled in the art can be made to the configuration and details of the present invention within the scope of the present invention. This application claims priority based on Japanese Patent Application No. 2008-1 3 1 440 filed on May 20, 2008, the entire disclosure of which is incorporated herein. Industrial applicability
- the present invention can be used not only for a photographing apparatus such as a digital camera but also for a portable information processing terminal having a photographing function such as a camera-equipped mobile phone.
