Embodiment Construction

[0042] The present invention will be described below with reference to the accompanying drawings as feasible examples for specifically realizing the above objectives.

[0043] FIG. 2 is a sequence diagram (flow chart) of a method for rapidly searching multiple still images according to the present invention. Using Figure 2 as a reference, we will introduce how to search multiple still images more quickly.

[0044] As shown in Figure 2, when compared with Figure 1 using the traditional technology, S203-1, S203-2, and S203-3 stages are added to the inverse discrete cosine transform (IDCT) stage, and the stage of displaying thumbnails is also divided into 3 types (S204-1, S204-2, S204-3), with diversification stages.

[0045] Carry out the input of still images compressed by DCT, stage S201, and the process of entropy multiplexing and inverse quantization of the above-mentioned input data, stage S202.

[0046] Moreover, decompress the still image data compressed by DCT into a d...

Abstract

This invention discloses a device and a method for quickly searching multiple static images from an image instrument including: symbolizing compressed static images with scattered cosine transformation, reducing the HF composition number checked out in said symbolization process to compute and displaying the symbolized multiple static images taking the reduced HF composition number as the primary standard.

Description

1. Technical field [0001] The present invention is an invention related to imaging equipment, more specifically a device and method for rapidly searching multiple still images. 2. Background technology [0002] Along with the rapid development of digital technology, it has contributed to the gradual popularization of digital TV, digital camera, digital camera mobile phone and so on. In addition, at the same time, a technology has been developed that can take advantage of the advantages of digital cameras, etc., and view photos in digital cameras on large-screen digital TVs. [0003] Also, the capacity of memory inserted into digital cameras tends to increase. Generally, the commonly used one is 128-256MB, and there are also more than 4GB memory cards on the market. [0004] For example, analyzing the storage capacity of a JPEG file in a memory card that can be inserted, an image of 1280*720 pixels (pixel) occupies 250KB, an image of 1600*1200 pixels (pixel) occupies 808KB,...
