Problems solved by technology

However, in this case, although a conversion procedure can be used to correct the screen to solve the situation of inconsistent brightness and color, this method consumes hardware computing resources and requires time-consuming corrections, resulting in the loss of the simple and fast browsing of the original thumbnails. kindness
For example, in a hand-held electronic device with a large screen size (such as a digital photo frame), the thumbnail information generated by the digital camera may not be suitable for browsing because the resolution is too small; it takes too much time to read the original image. Calculation time; even if the image correction of the thumbnail is performed by hardware calculation, it takes time to wait for the conversion procedure, which is quite inconvenient for the user

Embodiment Construction

[0026] The object of the present invention and its implementation method are described in detail in the following preferred embodiments. However, the concept of the invention can also be used in other areas. The following examples are only used to illustrate the purpose and implementation method of the present invention, and are not intended to limit the scope thereof.

[0027] In the following description, the Exchangeable image file format (Exchangeable image file format, EXIF ​​for short) refers to a data format specially set for photos taken by a digital camera. Those skilled in the art can easily understand that EXIF ​​information is mainly used to record additional attribute information and shooting information of digital photos, and can be added to files such as JPEG, TIFF, RIFF, etc., so manufacturers can add relevant digital cameras to digital photo files The content of shooting information (such as aperture, shutter speed, sensitivity, date), index map or any custom...

Abstract

The present invention relates to a method for generating the digital photo file. The digital photo file is a digital file in which a plurality of minimizing charts with different purposes are generated by an electronic device based on the photo data content and inlaid in the single image file. The digital photo file is characterized by comprising a plurality of picture contents with different purposes in the same file for printing photos, revising pictures of a computer, rapidly previewing photos and playing the photos in an electronic device with excellent picture quality and viewing speed.

Description

technical field [0001] The present invention relates to a method for generating a digital photo file, and in particular to a method for generating a digital photo file that embeds multiple photos in a single image file. Background technique [0002] With the advancement of digital camera technology, the resolution of digital photo files is getting larger and larger. In order to quickly display the composition and rough effect of the original picture on the handheld device, some digital cameras on the market will embed a thumbnail (thumbnail) in the original picture file when generating a digital photo, so as to quickly preview the composition of the photo. [0003] The thumbnails attached to the above digital photo files are basically thumbnails of the original images, which is a general-purpose format. It does not adjust the color and brightness display characteristics of the LCD on the handheld machine, so the quick preview thumbnail There may be inconsistencies in brigh...
