Image recording/reproduction apparatus, index displaying method by image recording/reproduction apparatus, and computer program

Abstract

An image recording/reproduction apparatus reads image data from a recording medium storing plural image data to display the read image data on a TV monitor or the like, and selects image data of a same aspect ratio to simultaneously index display plural small images of thus selected image data on the TV monitor. Reduced images of an aspect ratio of 4:3 and 16:9 are formed respectively from image data of an aspect ratio of 4:3 and 16:9, and the number of displayed small image is changed according to the aspect ratio, thereby displaying a larger amount of information within a limited display space in an easily recognizable manner.

1 . An image recording/reproduction apparatus comprising:
 a recording medium, on which plural image data of different sizes are recorded with information of the size of each of the plural image data;   a display unit, adapted to read and display the read image data from the recording medium; and   a discrimination unit, adapted to discriminate whether the image data recorded on the recording medium has a predetermined size among the different sizes, in accordance with the size information recorded on the recording medium;   wherein plural small images of the image data discriminated by the discrimination unit are simultaneously index displayed on the display unit.   
     
     
         2 . An image recording/reproduction apparatus according to  claim 1 , wherein only the small images of the image data having a same size are simultaneously index displayed. 
     
     
         3 . An image recording/reproduction apparatus according to  claim 2 , wherein the small image of the image data having a first size is trimmed so as to have the first size so that the image data of the first size and the small image thereof have the same first size. 
     
     
         4 . An image recording/reproduction apparatus according to  claim 1 , wherein the size is width and height of the image data. 
     
     
         5 . An index display method for controlling an image recording/reproduction apparatus including a recording medium on which plural image data of different sizes are recoded with information of the size of each of the plural image data, comprising:
 a step of discriminating whether the image data recorded on the recording medium has a predetermined size among the different sizes, in accordance with the size information recorded on the recording medium; and   a step of simultaneously index displaying plural small images of the image data discriminated in the discriminating step on a display unit.   
     
     
         6 . A computer readable program recorded on a computer readable storage medium, comprising a program code for causing a computer to execute an index display method set out in  claim 5 .
