It addition, CMOS (Complementary Metal-Oxide-Semiconductor), middle literature
Entitled complementary metal oxide semiconductors (CMOS), he is originally a kind of important chip in computer system, preserves
The data that System guides is most basic.It is poor that the manufacturing technology of CMOS and general computer chip do not have
Not, the quasiconductor made mainly by silicon and germanium both elements so that it is coexist on CMOS
Band N (band-electricity) and the quasiconductor of P (band+electricity) level, electricity produced by the two complementary effect
Stream can be processed chip record and be interpreted to image.Found that CMOS can also make through processing later
For the imageing sensor in digital photography.
For independent of the portable use of electrical network, the CMOS skill famous with low power consumption characteristic
Art has an obvious advantage: cmos image sensor is for 5V and 3.3V supply voltage
Design.CCD chip then needs the supply voltage of about 12V, therefore has to use one
Electric pressure converter, thus cause power consumption to increase.In terms of total power consumption, integrated with systemic-function controlling
Another benefit will be brought: it is all that he eliminates with other semiconductor elements in cmos sensor
External connection line.The driver of its high power consumption is abandoned the most, this is because carry out at chip internal
The energy that communication is consumed is more much lower than by the outside implementation of PCB or substrate.
Cmos sensor also can be subdivided into passive type element sensor (Passive Pixel Sensor
CMOS) with active pixel sensor (Active Pixel Sensor CMOS).
Passive type element sensor (Passive Pixel Sensor is called for short PPS), is again passive type picture
Element sensor, he is made up of a back-biased light sensitive diode and a switching tube.Photosensitive two poles
Pipe is substantially a PN junction being made up of P-type semiconductor and N-type semiconductor, and he can be equivalent to one
Individual back-biased diode and a mos capacitance parallel connection.When switching tube is opened, photosensitive two poles
Pipe connects with vertical alignment (Column bus).The charge integration amplifier being positioned at alignment end is read
Going out circuit (Charge integrating amplifier) keeps column line voltage to be a constant, when photosensitive two poles
The signal charge of pipe storage is when being read, and its voltage is reset to column line voltage level, meanwhile,
The electric charge being directly proportional to optical signal is converted to electric charge output by charge integration amplifier.
Active pixel sensor (Active Pixel Sensor is called for short APS), is again active picture
Element sensor.Almost while CMOS PPS dot structure is invented, it is rapidly be recognized that at picture
In element, introducing buffer or amplifier can improve the performance of pixel, each pixel in CMOS APS
Inside there is the amplifier of oneself.The transistor that amplifies being integrated in surface decreases effective table of pixel element
Area, reduces " packaging density ", makes the incident illumination of 40%～50% be reflected.This sensor
Another problem be how to make to have between the multichannel amplifier of sensor preferably coupling, this can
Preferably realize with the fixed pattern noise by reducing residual level.Due in CMOS APS pixel
Each amplifier only at this read during be excited, so CMOS APS power dissipation ratio CCD figure
The least as sensor.
In using the lift car of the present invention, child identifies system, lacks elevator car for prior art
The problem of the accurate testing mechanism of railway carriage or compartment child, uses high-resolution acquisition technology and high-precision
Image detecting technique completes to accurately identify lift car child, and gives associated monitoring department immediately
With monitoring personnel with corresponding information, thus when there is danger during children's ride-on elevator, it is possible to the
One arrangement of time Security Personnel, on site fault clearing, ensures the personal safety of child.
Although it is understood that the present invention discloses as above with preferred embodiment, but above-mentioned enforcement
Example is not limited to the present invention.For any those of ordinary skill in the art, without departing from
Under technical solution of the present invention ambit, all may utilize the technology contents of the disclosure above to the technology of the present invention
Scheme makes many possible variations and modification, or is revised as the Equivalent embodiments of equivalent variations.Therefore,
Every content without departing from technical solution of the present invention, the technical spirit of the foundation present invention is to above example
Any simple modification, equivalent variations and the modification done, all still falls within technical solution of the present invention protection
