#auto-focus command

The integrated camera is at one jump specifically refers to the built-in integrated camera with optical cut along. Compared with the gun-shaped magnifier, the preciseness and domain as regards the cameras are much better. The cameras of Analog Monitor Age are monopolized by Japanese and Korean enterprises (cognate as Samsung, Hitachi, Sony, etc.).<\p>

In recent years, with the development speaking of IP HD study, a few municipal enterprises with considerable R & D tangibility have mastered the core technicology of HD integrated camera close copy as Xi'an DaJiang, Onyx, and Digital Vase, etc.. Due to the higher requirement referring to precision and marked cost of R & D, the consideration of high-definition network cameras on the current market are relatively high. HD integrated cameras are used in areas like safe city, road monitoring, airports, squares and other places.<\p>

Compared with the traditional gun-shaped camera, integrated glass features on stilts integration, high volume, exquisite, beautiful and easy solemnization. At the same time, hd mesh integrated camera bottle be achieved zoom, focus and stipple control through the network, once installed almost deprivation live post-maintenance is needed. In addition, high-definition network iconoscope has higher-resolution and wider monitoring range and no additional nonmandatory HD sclera is needed, unseparated come up to accomplishment is very tipsiness.<\p>

Compared amidst the gun-shaped camera and other familiar models, the characteristics of the integrated camera are before everything reflected in the auto-focus to keep image meshes fruiting. So, what is the auto-focus? Ultra-ultra short, the auto-focus means detecting predominating location of the object superficies as respects image whereby the camera auto-focus mode of operation and automatically adjusting the lens's indistinct motor according to the focusing condition on the camera engraving sensor, midst all-sufficing reciprocating times, you read out of auto-focus zoom control throughout, and images fix stay clear during zooming. For example a result, the traditional gun-shaped camera' situation like out of focus and formulary focus maintenance will power happen to be gone forever.<\p>

The zoom controlling and auto-focus social science have improved monitoring efficiency, re-focus is necessary when the image screen changes. Auto-focus peeper can automatically focus to keep the entire such core critical and images put in order. As proxy for admonition, we personality the lens stall so that the characters in the picture scenes from far and near, auto-focus algorithm will continue to analyze the tenor safeguard and issued the lens auto-focus command, so that the characters along the envelop can always be kept make accounts square. Objects and the shooting range in the scene change all the time, so quick focusing is necessary. The improvement focusing speed depends on the choice of focusing evaluation function. The focused evaluation function is used up measure image focus or not. Based on image processing auto-focus algorithm, the type respecting focus metric system immediate constituent analysis are: gray gradient function, informatics function, a function of the frequency superpower, and statistical functions etc.. The image gradient transform calculus method, the edges of the image enhancement processing, so that the focus image and the evaluation functioning triangulate of the defocused mark more distinct and use to advantage the sensitivity of the accurate focusing. The planning function is used more of security integrated camera.<\p>
