Embodiment Construction

[0018] In order to make the object, technical solution and beneficial effects of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] In the image thumbnail production process provided by the embodiment of the present invention, the image is cut into multiple parts, and then the data of each part of the image is transferred into the memory one by one to make the thumbnail of the part of the image, and finally the thumbnails of each part of the image are Merge processing is performed to obtain a thumbnail of the entire image.

[0020] Such as figure 1 As shown, the image thumbnail creation process mainly includes the image data cutting stage, the thumbnail making processing stage for each piece of image data obt...

Abstract

The invention discloses an image thumbnail making method and a system thereof. The method comprises the following steps of: segmenting source image data into a plurality of image data segments; respectively calling each image data segment obtained by segmenting into a memory and generating thumbnail data according to the image data segments; and synthesizing the thumbnail data generated accordingto each image data segment to obtain thumbnails of a source image. Due to the adoption of the method, a final thumbnail of a large image is obtained by respectively making thumbnails of a small amount of data in batches in a mode of reading a large file into a memory in batches and splicing the thumbnails generated by the small amount of the data in sequence. Therefore, the problem that the conventional method consumes a large number of resources and cannot be used normally is overcome; the aims of high efficiency and low resource are fulfilled; and a very good preview effect can be achieved.

Description

technical field [0001] The invention relates to numerical image processing technology in the communication field, in particular to a method for making image thumbnails and a system thereof. Background technique [0002] In the digital image processing system, it is often necessary to manage and process image files of various sizes. In the process of management and processing, it is necessary to use the thumbnails of the images to preview and view, so the production or extraction of thumbnails requires certain methods. . [0003] The traditional method is to read all the original files of the image to be previewed into the memory, and then use the method of drawing lines or points to obtain the thumbnail of the image. For image files with a small amount of data, this method can also be processed; however, if you encounter special circumstances, you need to process images with a large amount of data (referring to the size of the disk occupied by the file), such as hundreds of...
