Description

  The present invention relates to an information processing apparatus, an imaging apparatus, an image file generation method, and an image display processing program that display image data.

  In recent years, in a portable information terminal having a photographing function such as a digital camera or a mobile phone, the size of image data that can be photographed or reproduced becomes larger than the size of the display unit as the resolution of the CCD increases. In such a portable information terminal, in general, when image data is reproduced and displayed on the display unit, the image data is reduced to fit the display size of the display unit so that the entire image data can be confirmed. In this case, the reduction ratio increases and it becomes difficult to confirm details of the image data. For this reason, an operation for moving the zoom or the zoom position is essential. In the conventional portable information terminal, when the user performs the enlargement / reduction operation of the image data himself or applies the conventional technology in the image processing technology and the image size is wider than the displayable size of the display unit, the number of times of scrolling is set.
