Problems solved by technology

[0004] However, for manufacturers, how to test the image capture device on the production line so that its shooting quality can reach a certain level has always been an important issue.
With traditional technology, manufacturers need to purchase many complex and expensive instruments to test the shooting quality of image capture devices
This not only increases the manufacturing cost, but also the operation process is complicated and time-consuming, which is not suitable for execution on the production line
And if it is identified manually, there is no uniform standard, so that there is a considerable error

Embodiment Construction

[0015] figure 1 Shown is an internal block diagram of a detection device of an image capture device according to a preferred embodiment of the present invention. Please refer to figure 1 , the detection device 100 of the present invention can be used to detect the shooting quality of the image capture device 140 . In this embodiment, the image capture device 140 may be a static image capture device, such as a digital camera, a color / black and white photocopier, a multifunction machine, a fax machine, etc., or a dynamic image capture device, such as Digital video cameras, network cameras, etc.

[0016] The detection device 100 provided by the present invention includes a watermark embedding module 110 and an analysis module 120, and the two are coupled to each other. The watermark embedding module 110 is used to generate a test image TE0 with a digital watermark to the image capture device 140 for shooting. The analysis module 120 receives the test pattern TE1 output by the...

Abstract

The invention discloses a method for detecting an image acquisition device, and the method comprises the step that a test pattern embedded with a digital watermark is produced for shooting the image acquisition device. Additionally, the test pattern output by the image acquisition device is also received and the digital watermark processed by the image acquisition device is extracted from the testpattern by the invention, thereby the extracted digital watermark can be compared with the original digital watermark and the shooting quality of the image acquisition device is determined based on the comparative results.

Description

technical field [0001] The present invention relates to a detection method of an image capture device, and in particular to a detection method of an image capture device using a digital watermark. Background technique [0002] In recent years, with the great progress of digital technology, coupled with the high development of Internet and multimedia technology, many images hope to be converted into digital images for processing. Therefore, digital camera (Digital Camera), digital video recorder (DVR), network camera (Web Cam) and other image capture devices are used to directly capture the physical scene, and convert it into digital image data output to benefit users Display, recognize (OCR), edit, store and output digital image files on computers or other electronic products. [0003] Due to the use of digital image capture devices to directly capture physical scenes, compared with traditional devices, in addition to using digital methods for storage and editing, and becau...
