Image thumbnail browsing device and method thereof

The present invention relates to an apparatus for image access and browsing and a method thereof.

The storage preview of the image multimedia is to view the thumbnail image through the preview window, thereby selecting the image to be viewed, generally through the page change design, and the user can view the preview icon by page.

Since a general digital camera records a stored image via a mass storage device such as a secure digital card (secure digital card), there are operations such as opening, reading, and file seek. In addition, because the processing speed of the secure digital card is not uniform, such as the so-called fast card and slow card, the operation of opening and reading will be caused by different security digital cards, resulting in a large speed variation, for example: The preview of the 3X3 nine-square grid needs to repeat the above actions nine times. If you want to repeat the reading, you need to re-analyze the maps.

Since the contents of different JPEG interchangeable image file headers (EXIF headers) are different, the header file for parsing JPEGs may also vary due to the complexity of the contents of the exchangeable image files. And the prior art cannot judge the images that are often viewed.

In recent years, with the increase of touch devices, the improvement of the touch experience has become an indispensable task for touch devices. For example, the page change mode of the original click button has now become a slide page change. Even with the inertial sliding method, the user can view the preview image by sliding multiple pages at a time. In order to respond to this switching mode, it is necessary to let the hardware improve the speed of the solution preview, in order to meet the user requirements, hardware and specifications, in order to improve the display file, it is necessary to reduce the processing flow and variability. With this in mind, this proposal provides a quick way to unravel small icons for a large preview.

Because the prior art has the inconsistent processing speed of the secure digital card, the need to re-analyze the image file after repeated reading, and the inability to judge the frequently viewed image, the present invention is based on the above considerations and proposes to utilize a latest access table (lastest access table). Quickly accessing the thumbnail of the corresponding image, and changing the index in the latest access table and the image thumbnail method pointed to by the index according to the file accessed by the user, and processing the foregoing problem.

The image thumbnail preview method of the present invention will be described in detail below with reference to the drawings, and the same steps will be denoted by the same symbols.
