Embodiment Construction

[0019] The structure diagram of the camera in this invention is as follows figure 1 As shown, its specific implementation is as follows:

[0020] 1. The use of microprocessors

[0021] In order to improve the function of the microprocessor, the microprocessor adopted is ARM9 series.

[0022] 2. Add "Description Information Embedded Processing Module"

[0023] On the basis of the traditional digital camera, a new module is added as "descriptive information embedding processing module", which is responsible for embedding the descriptive information into the digital camera.

[0024] The algorithm in this part is described as figure 2 shown.

[0025] The implementation framework of this part is as follows image 3 shown.

[0026] 3. Embedding algorithm for explaining information

[0027] The watermark embedding process is divided into: lifting wavelet transform, least effective position zero, description information processing, embedding watermark information, inverse lift...

Abstract

The invention relates to a camera capable of embedding descriptive information in the photo, belonging to the fields of the computer application, the digital product application, the mode identification, the image processing and the like. The camera is capable of taking a photo and embedding descriptive information in the photo with the digital watermarking technology. To make the descriptive information embedded in the photo resist the impact from compressing, scaling and filtering, the watermark is embedded in the photo with the robust digital watermarking technology in such a way of lifting wavelets in the two layers of the photo, returning the lowest effective position of the obtained low-frequency subband to zero, transforming the descriptive information into a binary image and embedding the binary image in the lowest effective position of the low-frequency subband. The camera is capable of taking a photo and embedding descriptive information in the photo, can be widely applied to the crime investigation field, the claim settlement field and other places needing to embed descriptive information in the photo in time and can be used for taking a photo in the daily life.

Description

technical field [0001] The invention is a camera capable of adding explanatory information to photos, and belongs to the technical fields of computer application, digital product application, pattern recognition, and image processing. Background technique [0002] At present, the use of digital cameras has been quite common. People often take a large number of photos as souvenirs, but they often forget the relevant background information when browsing the photos again because they are too late to organize them. This photo was taken at the scene. In addition, in some special fields, such as criminal investigation scene, insurance claims scene, etc., it is usually necessary to immediately make relevant descriptions of the scene of the photographed photos. At present, the description of photos is usually implemented separately from the photos, which brings great inconvenience to the use. [0003] Digital watermarking technology is a technology that embeds information in the s...
