Abstract
The invention discloses a method for manually focusing a high definition serial digital interface (HD-SDI) camera or an internet protocol (IP) network camera which is rapidly, easily and conveniently focused on a construction site. The method comprises the following steps that: (1) real-time operation is performed on an input image signal by utilizing an internet service provider (ISP) chip or a digital signal processor (DSP) chip of the camera so as to judge the focusing sharpness of an image in real time; (2) a buzzer circuit with programmable sound frequency is arranged in the camera; (3) a buzzer does not sound when a user starts to manually adjust a focusing knob of a lens; (4) along with adjustment of the user, the buzzer immediately sounds when the ISP chip or the DSP chip determines that the image is focused, and the sound is fed back to the user; and (5) the user stops the focusing operation, and the knob is locked until the image focusing is completed.
Description
Technical field
The invention belongs to the technical field of video monitoring equipment control; Be specifically related to HD-SDI (High-definition serial digital interface; The high definition digital serial line interface) manual focusing method of video camera or IP (Internet Protocol, Internet protocol) web camera.
Background technology
Video camera focusing method at the construction field (site) relates to following several kinds:
1. common SD analog video camera.The simulation SD video camera that is widely used now, what video was exported is the CVBS TV signal of standard, can directly connect video monitor or televisor, also portable televisions that adopt on engineering more.Camera lens is being focused when operation, can synchronous real-time supervising focal length and whether adjust to the right place.
2.HD-SDI high-definition digital video camera.The engineering construction scene need be adjusted the focal length of camera lens according to field scene; But the rate video signal of HD-SDI high-definition digital video camera output is 1.485Gb/s or 2.97Gb/s; Can not be directly connected to by widely used video monitor of institute or televisor on the engineering; On the other hand, mostly present ubiquitous video monitor or portable television are SD, can not directly carry out the demonstration of high-definition video signal.So how HD-SDI high-definition digital video camera accomplishes the adjustment work of camera lens fast at engineering site, is a difficult problem that needs to be resolved hurrily.
3.IP web camera.Mostly the signal output of IP network video camera is Ethernet interface, and video, audio frequency, control signal all can be transmitted through the Ethernet netting twine.But widely used video monitor of institute or televisor do not have ethernet network interface now, even have ethernet network interface, procotol also is difficult for compatible.Also there is time delay in video transmission on the Ethernet, is unfavorable for the real-time adjustment of engineering site lens parameters.So how the IP network video camera accomplishes the adjustment work of camera lens fast at engineering site, is a difficult problem that needs to be resolved hurrily.
4. individual other HD-SDI high-definition camera and IP network video camera all have CVBS (Composite Video Broadcast Signal, Composite Video Broadcast Signal) analog video output interface, can plug into SD video monitor or televisor.But in the engineering construction erecting stage, equipment such as video camera all is erected at eminence, the video monitor of plugging into also is not easy, and has brought many difficult problems for on-site construction operations person.
Summary of the invention
Technology of the present invention is dealt with problems and is: overcome the deficiency of prior art, a kind of quick at the construction field (site), the HD-SDI video camera of easy focusing or the manual focusing method of IP network video camera are provided.
Technical solution of the present invention is: the manual focusing method of this HD-SDI video camera or IP network video camera may further comprise the steps:
(1) utilize the ISP chip of video camera or dsp chip that the picture signal of input is carried out real-time operation, the sharpness of real-time judge image focusing;
(2) buzzer circuit is set in video camera, its sound frequency is able to programme;
(3) when the user had just begun the focusing knob of manual adjustments camera lens, hummer is sounding not;
(4) along with user's adjustment, when ISP chip or dsp chip were confirmed image to the part of the body cavity above the diaphragm housing the heart and lungs, hummer sent the sound immediately, feeds back to the user;
(5) user stops the focusing operation, locks knob, and image focusing so far finishes.
Confirm ISP chip or the dsp chip whether image focuses and remind the buzzer circuit of usefulness through in video camera, being provided with, thereby realized quick at the construction field (site), easy focusing.
Description of drawings
Fig. 1 is the process flow diagram according to the manual focusing method of HD-SDI video camera of the present invention or IP network video camera.
Embodiment
As shown in Figure 1, the manual focusing method of this HD-SDI video camera or IP network video camera may further comprise the steps:
(1) utilize the ISP chip of video camera or dsp chip that the picture signal of input is carried out real-time operation, the sharpness of real-time judge image focusing;
(2) buzzer circuit is set in video camera, its sound frequency is able to programme;
(3) when the user had just begun the focusing knob of manual adjustments camera lens, hummer is sounding not;
(4) along with user's adjustment, when ISP chip or dsp chip were confirmed image to the part of the body cavity above the diaphragm housing the heart and lungs, hummer sent the sound immediately, feeds back to the user;
(5) user stops the focusing operation, locks knob, and image focusing so far finishes.
Confirm ISP chip or the dsp chip whether image focuses and remind the buzzer circuit of usefulness through in video camera, being provided with, thereby realized quick at the construction field (site), easy focusing.
The above; It only is preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs to the protection domain of technical scheme of the present invention to any simple modification, equivalent variations and modification that above embodiment did.
Claims (1)
1.HD-SDI the manual focusing method of video camera or IP network video camera is characterized in that, may further comprise the steps:
(1) utilize the ISP chip of video camera or dsp chip that the picture signal of input is carried out real-time operation, the sharpness of real-time judge image focusing;
(2) a buzzer circuit device is set in video camera, its sound frequency is able to programme;
(3) when the user had just begun the focusing knob of manual adjustments camera lens, hummer is sounding not;
(4) along with user's adjustment, when ISP chip or dsp chip were confirmed image to the part of the body cavity above the diaphragm housing the heart and lungs, hummer sent the sound immediately, feeds back to the user;
(5) user stops the focusing operation, locks knob, and image focusing so far finishes.
