    • In an initial stage where an image obtained by image sensing is displayed, image data in a resolution depending on an image display area of display unit is displayed, thereby a high response can be maintained with respect to a request to display a next image or the like. Further, if a request with an enlargement ratio higher than that in the initial stage has been made, a display image is generated based on image data in a high resolution, thereby a user's request for enlarged display or the like can be fulfilled. When an image (JPEG file) stored in a recording medium is to be displayed, low resolution image data in 640×480 pixel size equivalent to the resolution of the display unit and high resolution image data in an original high resolution indicated with the image file are generated. In the initial stage, the low resolution image data is displayed. If an enlargement request has been made, partial image data cut out from the high resolution image data is resized and is displayed.
    • 在通过图像感测获得的图像被显示的初始阶段中,显示根据显示单元的图像显示区域的分辨率的图像数据,从而可以相对于显示下一个图像的请求而保持高响应,或者 喜欢。 此外,如果已经做出了具有高于初始阶段的放大率的请求,则基于高分辨率的图像数据生成显示图像,从而可以满足用户对放大显示等的请求。 当要显示存储在记录介质中的图像(JPEG文件)时,生成与显示单元的分辨率相当的640×480像素尺寸的低分辨率图像数据和以图像文件指示的原始高分辨率的高分辨率图像数据 。 在初始阶段,显示低分辨率图像数据。 如果已经进行放大请求,则从高分辨率图像数据切出的部分图像数据被调整大小并被显示。
