Description
Technical field
The utility model relates to field of video processing, particularly relates to a kind of video intensifier.
Background technology
Visual information is the human main source that obtains external information, because nearly 70% information obtains through human eye.Along with the multimedia technology develop rapidly, video image has obtained extensive attention and application.And application spreads all over aspects such as radio and television, medical science, guard monitor, parking lot management, military affairs and life science.The lifting of video acquisition technology and Display Technique, make people to image quality require increasingly high.But the transmission of image and conversion cause the reduction of picture quality always to a certain extent in all kinds of picture systems.For example: some outdoor supervisory control systems often can only be under fine day could operate as normal, reduce greatly at bad weather such as dense fog, sand and dust or low light situation hypograph contrast, people can't therefrom obtain useful information.Moreover, watch the low video of quality may increase the weight of the burden of people's eyes for a long time, be easy to generate visual fatigue, even can have a dizzy spell.When bad weather such as dense fog, heavy rain, sand and dust occurring, the contrast of outdoor scene image and color all can be changed or degenerate, and the many characteristics that contain in the image all are capped or are fuzzy, have all caused great difficulty for all kinds of monitoring.Therefore, give full play to the usefulness of monitoring video, just must carry out enhancement process the monitoring video image.
At present, it is poor that the dedicated video intensifier that occurs on the market is handled the real-time of mass data information, and can only handle monistic data, in reality, can not be applied.
The utility model content
The purpose of the utility model is that for addressing the above problem, the utility model proposes a kind of video intensifier, makes and in reality, is applied.
For realizing above-mentioned utility model purpose, the utility model proposes a kind of video intensifier, it is characterized in that, this video intensifier comprises: a plurality of Video Decoders, with decoder video encoder and video processor correspondingly;
The output of said Video Decoder links to each other with the input of said video processor; The output of said video processor links to each other with said video encoder input;
The input of said Video Decoder is imported the vision signal of corresponding form; Video Decoder through correspondence obtains digital video signal; Export corresponding video encoder to after the mist elimination of the said video processor of digital video signal process and the low-light (level) enhancement process, the video after the said video encoder output enhancement process.
Said Video Decoder comprises: composite video decoder, VGA decoding signals and HDMI decoding signals.
Said video encoder comprises: composite video encoder, VGA signal coder and HDMI signal coder.
Said video encoder and said Video Decoder all adopt the I2C interface configuration.
The advantage of the utility model is; The device of the utility model is widely used in searching and breakdown lorry, TV monitor system, outdoor TV relay, flight navigation help, highway communication monitoring, hospital's health check-up imaging, the scheduling on airport, port dispatching, detecting under water, security protection are used or the like the field that needs video to strengthen; And improved the speed of handling mass data information, for real-time is laid a good foundation.In addition, this device can be handled the data message of various forms simultaneously, can in reality, apply on a large scale.
Description of drawings
Fig. 1 is a kind of video intensifier block diagram of the utility model;
Embodiment
Below in conjunction with accompanying drawing and embodiment, the method for the utility model is carried out further detailed explanation.
Of Fig. 1, Fig. 1 is a kind of video intensifier block diagram of the utility model.Device is made up of three decoders, three encoders and a video processor among the figure.The vision signal of three kinds of forms inputs to corresponding decoder and obtains digital video signal; Pass the signal to mist elimination processing and low-light (level) enhancement process that video processor carries out video, the signal that will handle at last is through corresponding video coding chip output video.Wherein, three decoders are respectively: composite video decoder, VGA decoding signals and HDMI decoding signals.Accordingly, three encoders are respectively: composite video encoder, VGA signal coder and HDMI signal coder.
The composite video decoder is the SAA7113 video decode family chip that adopts PHILIPS Co., and the main effect of SAA7113 is " VPO " digital signal that is decoded into the analog video signal of input standard, is equivalent to a kind of " A/D " device.7113 compatible global various video standards.
The compound video code chip is the ADV7170 integrated form digital video code that adopts ANALOG DEVICES company, can be the standard analog base-band television signal compatible with global standards with digital CCIR-6014:2:28 position or 16 component vide data transaction.
The VGA decoding signals is the AD9883 that adopts ANALOG DEVICES company, and 3 tunnel 8 modulus switching devices, maximum transfer ratio reach 140MS/s (1,000,000 sampling/per seconds), are used for catching the rgb signal of personal computer or work station more.
The VGA signal coder is the ADV7123 that adopts ANALOG DEVICES company; Be a single-chip, triple channel, high-speed A/D converter, the video dac of built-in three high speeds, 10, band complementary output, standard TTL input interface and high impedance, analog output current source.
The HDMI decoding signals is the SiI9135 that adopts Silicon Image company; Be a advanced person's dual input HDMI
receiver, be designed for the digital A/V receiver of high definition (HD).
The HDMI signal coder is the SiI9134 that adopts Silicon Image company, is advanced HDMI 1.3 transmitters, supports the resolution up to 1080p at 60Hz; 36 color depths; The audio format of Dolby True HD and high bit rate provides and enriches digital video and audio experience, is widely used in home theater such as DVD player and CD writer; The A/V receiver, top box of digital machine and PVR.
Video processor is the large-scale F PGA that adopts CYCLONE company, is a kind of programmable gate array chip, can the high speed processing mass data.
Video encoder and Video Decoder be respectively through the I2C interface configuration, need configuring chip mode of operation, video format, check operating state etc.Wherein, I2C is the chip chamber serial transmission bus that Philips company releases, and can realize perfect full duplex synchronous data transmission with SDA and two lines of SCL, has that standard is complete, structure independence and use characteristics such as simple.The clock line SCL and the data wire SDA of I2C bus are reversible line.Every transmission one digit number is according to all requiring to have on the clock line 1 clock pulse corresponding with it on the data wire.
The I2C bus data transmits and comprises three kinds of important time sequence status initial signal, termination signal and answer signals:
(1) initial signal: keep between high period at clock line, data wire occurs when low level changes, starting the I2C bus by high level;
(2) termination signal: keep between high period at clock line, data wire occurs when high level changes, stopping the I2C bus by low level;
(3) answer signal: when the I2C bus data transmits, all answer signal must be arranged after byte data of every transmission, answer signal occurs on the 9th clock bit, and the receiver output low level is answer signal (A), the output high level then be non-answer signal (/A).
It should be noted last that above embodiment is only unrestricted in order to the technical scheme of explanation the utility model.Although the utility model is specified with reference to embodiment; Those of ordinary skill in the art is to be understood that; The technical scheme of the utility model is made amendment or is equal to replacement; The spirit and the scope that do not break away from the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
