Definitions
- the present invention relates to an image display device suitable for use in displaying a list of image files, an image list display method, and an image list display program.
- EXif registered trademark
- EXchangeable Image File format EXchangeable Image File format
- An Exif (registered trademark) format image file includes camera information and thumbnail image data in addition to main image data. Thumbnail image data is smaller in data amount than high-pixel main image data and can be processed at high speed. For this reason, if a thumbnail image included in an image file in the Exif (registered trademark) format is used, a list of images can be quickly displayed.
- the main image has a vertically long image and a horizontally long image, and there are images with various aspect ratios (aspect ratios).
- the aspect ratio is “4: 3” and the image size is “160 ⁇ 120”.
- the thumbnail image stores a reduced main image while maintaining the aspect ratio. For this reason, when an image list is created using thumbnail images included in an Exif (registered trademark) image file, a blank portion may appear in the display portion.
- FIG. 9 shows a case where the main image 501 in the Exif (registered trademark) format image file is a vertically long image. Since the thumbnail image of an Exif (registered trademark) image file is a horizontally long image having an aspect ratio of “4: 3”, it does not match the vertically long image. Therefore, when the main image 501 in the Exif (registered trademark) format image file is vertically long, as shown in FIG. 9, margin portions (indicated by diagonal lines) are generated in the thumbnail image 502 corresponding thereto.
- FIG. 10 shows a case where the aspect ratio of the main image 601 in the image file in the Exif (registered trademark) format is longer than “4: 3” (for example, the aspect ratio “16: 9”).
- the thumbnail image of an Exif (registered trademark) image file has an aspect ratio of “4: 3”, and thus does not match an image with an aspect ratio of “16: 9”. Therefore, when the aspect ratio of the main image 601 in the Exif (registered trademark) format image file is “16: 9”, the thumbnail image 602 corresponding to the aspect ratio has upper and lower margins as shown in FIG.

Abstract
Description
<第1の実施形態>
図1は、本発明の第1の実施形態に係る画像表示装置であるカメラ付き携帯電話機1の構成を示すブロック図である。図1に示すように、カメラ付き携帯電話機1は、撮像装置21と、制御部22と、内蔵アンテナ23と、無線部24と、信号処理部25と、スピーカ27と、マイクロホン28と、音声処理部29と、記憶部30と、表示部31と、各種キー32とを備えている。
画像ファイル抽出部51は、記憶部30からExif(登録商標)形式の画像ファイルを読み出し、この読み出された画像ファイルに含まれているサムネイル画像を抽出する。
正方形画像生成部52は、画像ファイル抽出部51が抽出したサムネイル画像から正方形状の表示画像を生成する。
サムネイル画像は、規格によりアスペクト比「4:3」、画像サイズ「160×120」と規定されている。また、サムネイル画像には、アスペクト比を保持して縮小されたメイン画像の領域である有効画像領域が含まれる。
次に、本発明の第2の実施形態について説明する。前述の第1の実施形態における画像表示装置は、Exif(登録商標)形式の画像ファイルに含まれているサムネイル画像を抽出し、このサムネイル画像を有効画像領域の短辺を表示画像の一辺に合わせてリサイズし、このリサイズした画像の中心を検出し、このリサイズした画像の中心から正方形状の画像を切り出して、所定サイズの正方形状の表示画像を生成している。
具体的には、制御部22は、サムネイル画像に含まれる有効画像領域の中心を通る有効画像領域の短辺の各画素が全て含まれるように正方形状の画像を切り出す。そして、制御部22は、この切り出された正方形状の切り出し画像の一辺のサイズが、正方形状の表示画像の一辺のサイズとなるようにリサイズする(ステップ204)。これにより、有効画像領域の中心を通る有効画像領域の短辺の各画素に対応する画素が全て含まれる、所定サイズの正方形状の表示画像が生成される。そして、制御部22は、生成された正方形状の画像を一覧表示画像として表示する(ステップ205)。
なお、本実施形態では、一覧表示する表示画像として所定サイズの正方形状の画像を用いる場合を説明したが、これに限られず、所定サイズの矩形画像を用いても良い。
例えば、表示画像として「160×120」の矩形画像を用いる場合、まず、制御部22は、有効画像領域の短辺が横方向であるか縦方向であるかを判定する。有効画像領域の短辺が横方向である場合、有効画像領域の短辺のサイズが、表示画像の横方向の辺のサイズ、即ち160となるように、サムネイル画像のサイズを、アスペクト比を保持して変更してリサイズする。他方、有効画像領域の短辺が縦方向である場合、有効画像領域の短辺のサイズが、表示画像の縦方向の辺のサイズ、即ち120となるように、サムネイル画像のサイズを、アスペクト比を保持して変更してリサイズする。
このような処理により、第1の実施形態において矩形画像を表示画像として用いることができる。
例えば、表示画像として「160×120(アスペクト比4:3)」の矩形画像を用い、サムネイル画像の有効画像領域のサイズが「160×90」である場合、制御部22は、「120×90(アスペクト比4:3)」の矩形画像を切り出す。
他方、表示画像として「160×120(アスペクト比4:3)」の矩形画像を用い、サムネイル画像の有効画像領域のサイズが「100×120」である場合、制御部22は、「100×75(アスペクト比4:3)」の矩形画像を切り出す。
このような処理により、第2の実施形態において矩形画像を表示画像として用いることができる。
