  In step S2, the microcomputer 2 extracts an image of a word included in the processing image data 80a included in the processing image file 80 (step S2).

  Next, the microcomputer 2 recognizes the extracted word image as a character by comparing the extracted word image with a predetermined character pattern (step S3). A word recognized as a character is a keyword. A predetermined character pattern is incorporated in the image search program 40.

  Next, the microcomputer 2 recognizes the character size of the keyword extracted from the in-process image data 80a included in the in-process image file 80 (step S4).

  When the microcomputer 2 cannot extract a keyword by the keyword extraction process (step S1) (step S5: No), the microcomputer 2 is a video based on the processing image data 80a included in the processing image file 80. The signal output is continued, and the image of the processing image data 80a is displayed on the display 3 (step S6). On the other hand, when the microcomputer 2 can extract the keyword by the keyword extraction process (step S1) (step S5: Yes), the process of the microcomputer 2 proceeds to step S7.

Specifically, the microcomputer 2 checks whether the latitude data 80d and longitude data 80e included in each image file 80 satisfies the shooting position search condition, thereby checking the latitude data 80d and longitude satisfying the shooting position search condition. The image file 80 having the data 80e is searched. Further, the microcomputer 2 checks whether or not the image data 80a, the shooting time data 80c, and the altitude data 80f included in each image file 80 satisfying the shooting position search condition satisfy the associative search condition. The image file 80 including the image data 80a, the shooting time data 80c, and the altitude data 80f that satisfy the condition is searched. The search range may be all the image files 80 stored in the storage unit 4 or a part of them, or all the image files 80 stored in the external storage unit 8 or a part of them. It may be a part, or may be all the image files 80 stored in the storage unit 4 and the external storage unit 8 or a part of them. The search method may be a Grep type search method or an index type search method.

  Next, the microcomputer 2 outputs a video signal based on the image data 80a or the thumbnail image data 80b included in the one or more image files 80 searched in step S9 to the display 3, and the image data 80a or the thumbnail image data. The 80b image is displayed on the display 3 (step S10). When a plurality of image files 80 are retrieved, the microcomputer 2 performs a display process such as one of the following (a) to (c).

(A) The microcomputer 2 causes the display 3 to sequentially display images of the image data 80a included in the plurality of image files 80 searched in step S9.

(B) The microcomputer 2 reduces the images of the image data 80a included in the plurality of image files 80 searched in step S9 and displays them collectively on the display 3. If the images of the image data 80a included in all the image files 80 searched in step S9 cannot be displayed at a time, the microcomputer 2 sets the number of the plurality of image files 80 searched in step S9. The image data 80a is reduced for each group and displayed in a batch.

(C) The microcomputer 2 displays on the display 3 the images of the thumbnail image data 80b included in the plurality of image files 80 searched in step S9 in a lump. If the images of the thumbnail image data 80b included in all the image files 80 searched in step S9 cannot be displayed at once, the microcomputer 2 displays the plurality of image files 80 searched in step S9. Divided into several groups, the images of the thumbnail image data 80b are collectively displayed for each group.

  Thereafter, the processing based on the image search program 40 ends.

  According to the above embodiment, the image being displayed and the image displayed next (the image displayed in step S10) are related. For example, if the keyword extracted from the image being displayed is “Mount A”, an image taken at “Mount A” is displayed in step S10. Therefore, the interest about the display order of images is improved.

  If there are a plurality of keywords extracted in step S1, an image related to the keyword having the largest character size is displayed next (step S10). Characters drawn large in the displayed image are often keywords representing the main theme of the image. Therefore, the relevance between the image displayed in step S10 and the image displayed before that increases.
