Image index structure

Abstract

The invention provides an image index structure comprising a content data part and a header part, wherein the content data part comprises a plurality of micro-image units, and an area occupied by the content data part is distinguished into a plurality of status areas; each status area is provided with one micro-image unit, and the micro-image unit is selectively positioned in one of a plurality of virtual areas formed by equipartition status areas; and the header part comprises a plurality of micro-image units, and the micro-image units are arrayed in a predetermined way to provide header information for identifying an image index. The invention can be used for providing lower density of the micro-image units and forming the image index by using a small number of the micro-image units.

Description

[0001] This application is a divisional application of an invention patent application with an application date of April 26, 2006, an application number of 200610075770.8, and an invention title of "Image Index Structure". technical field [0002] The invention relates to image recognition (pattern / image recognition) technology, specifically a data output and input method using an image index structure. Background technique [0003] figure 1 It is a schematic diagram of a graphical indicator 102 formed on a surface 100 of an object. Such as figure 1 As shown, the image indicator 102 is composed of many micro image units. Since the micro image unit is quite small, it is easy to be ignored visually, or interpreted as the background color by human eyes. Image index 102 and main information (main information) 104 (such as figure 1 The character pattern "APPLE") is jointly formed on the surface 100 of an object such as paper by means of, for example, printing. The image inde...

Problems solved by technology

[0006] like figure 1 As shown, the image index 102 usually coexists with the main information 104 on the object surface 100; therefore, when the density of the micro-image unit is higher, the visual effect is worse, and the human eye is more likely to perceive the existence of the image index 102 and make the image index 102 Increased chance of confusion with main message 104

On the other hand, when the image index 102 is formed in a limited object surface area, under the premise of providing the same amount of information, the excessively high distribution density of micro-image units will cause the distance between two adjacent micro-image units to be too small; therefore , when the micro-image units are formed on the paper by, for example, printing, it will cause more obvious visual disturbance

If this visual interference is to be reduced, it is usually necessary to further reduce the size of the micro-image unit, which will increase the resolution requirements of the printing press and paper, and it is also easy to miss dots during printing, which relatively increases the difficulty of printing and is likely to cause damage to the optical device. Misinterpreted or difficult to distinguish

image 3 The design of the existing image index 102 shown clearly leads to an excessively high density of micro-image units, thereby causing the above-mentioned various problems
