In addition, CMOS (Complementary Metal-Oxide-Semiconductor), Chinese scientific name is complementary metal
Oxide semiconductor, he is originally a kind of important chip in computer system, saves the most basic data of System guides.CMOS
Manufacturing technology and general computer chip do not have a difference, mainly partly led using what silicon and germanium both elements were made
Body, it is set to co-exist the semiconductor with N (band-electricity) and P (band+electricity) level, electricity caused by the two complementary effects on CMOS
Stream, which can be processed, chip record and is interpreted to image.Found that CMOS can also be as the figure in digital photography by processing later
As sensor.
For the portable use independently of power network, the CMOS technology famous with low power consumption characteristic is bright with one
Aobvious advantage：Cmos image sensor designs for 5V and 3.3V supply voltages.And CCD chip then needs about 12V
Supply voltage, therefore have to use an electric pressure converter, so as to cause power consumption to increase.In terms of total power consumption, control
Another benefit will be brought by being integrated into systemic-function in cmos sensor：He eliminates all outer with other semiconductor elements
Portion's connecting line.Nowadays the driver of its high power consumption has been abandoned, because the consumed energy that communicated in chip internal
It is more much lower than the outside implementation by PCB or substrate.
Cmos sensor can also be subdivided into passive type element sensor (Passive Pixel Sensor CMOS) and active
Formula element sensor (Active Pixel Sensor CMOS).
Passive type element sensor (Passive Pixel Sensor, abbreviation PPS), is called passive type element sensor,
He is made up of the photodiode and a switching tube of reverse bias.Photodiode is substantially one is partly led by p-type
The PN junction of body and N-type semiconductor composition, he can be equivalent to reverse bias diode and a mos capacitance parallel connection.When opening
When closing pipe unlatching, photodiode connects with vertical alignment (Column bus).Charge integration positioned at alignment end amplifies
Device reading circuit (Charge integrating amplifier) holding column line voltage is a constant, when photodiode stores
Signal charge when being read, its voltage is reset to column line voltage level, at the same time, the electric charge directly proportional to optical signal by
Charge integration amplifier is converted to electric charge output.
Active pixel sensor (Active Pixel Sensor, abbreviation APS), is called active element sensor.It is several
While CMOS PPS dot structures are invented, it is rapidly be recognized that buffer or amplifier are introduced in pixel to be changed
The performance of kind pixel, there is the amplifier of oneself in CMOS APS in each pixel.The amplifying transistor for being integrated in surface subtracts
Lack the effective surface area of pixel element, reduced " packaging density ", reflected 40%~50% incident light.This sensing
Another problem of device is how to make having preferable matching between the multi-channel amplifier of sensor, and this can be residual by reducing
Remaining horizontal fixed pattern noise is preferably realized.Quilt during only being read herein due to each amplifier in CMOS APS pixels
Excite, so CMOS APS power dissipation ratio ccd image sensor is also small.
Using the arenas control method of cooling fan of the present invention, can not be provided i.e. for live performance personnel for prior art
When the radiating strategy and low technical problem of field apparatus automatization level, completed by a series of intelligent detection equipments to existing
The detection of field various parameters, the control to live various parameters is also completed by the control mode of structural control device, so as to avoid
Severe arena environment occurs, and ensures normal, the efficient progress of arenas performance.
It is understood that although the present invention is disclosed as above with preferred embodiment, but above-described embodiment and it is not used to
Limit the present invention.For any those skilled in the art, without departing from the scope of the technical proposal of the invention,
Many possible changes and modifications are all made to technical solution of the present invention using the technology contents of the disclosure above, or are revised as
With the equivalent embodiment of change.Therefore, every content without departing from technical solution of the present invention, the technical spirit pair according to the present invention
