Wherein, brightness detector, brightness regulator and imaging sensor are integrated in same SOC chip.
In addition, the data uploading device uses frequency duplex communications interface.Frequency division duplex refers to uplink and downlink
The transmission of link carries out over different frequencies respectively.
In mode of frequency division duplexing, the transmission of uplink and downlink carries out over different frequencies respectively.It is former
Reason is as shown below.F1 and f2 is respectively carrying out the transmission frequency and receives frequency of a certain mobile station of business transmission.
In the first and second generation cellular system, it is substantially and duplex transmission is realized using FDD technologies.Especially
In generation cellular system, baseband signal is continuous due to transmission, it is necessary to the uplink and downlink of duplex is provided with different frequencies
Link channel.When transmitting continuous information using FDD technologies in first generation cellular system, transmitting-receiving two-end must all have generation different
The frequency synthesizer of carrier frequency, receiving terminal must also there are one prevent transmitting signals leakiness to receiver duplex filter
Device.In addition, for the ease of the making of duplexer, there is certain frequency interval between transmitting-receiving carrier frequency.In the second generation
In the systems such as GSM, IS-136 and IS-95, FDD technologies are also used.In such systems, due to information be with slotted mode into
Row transmission, transmitting-receiving can carry out in different time slots, and the transmitting signal of mobile station or base station will not generate this receiver
Interference.So although with FDD technologies, do not need expensive duplexer filter yet.
The characteristics of fdd mode is the system on two symmetrical frequency channels of separation (uplink and downlink frequency interval 190MHz)
It is received and is transmitted, reception and transmission channel are detached with protection frequency range.
Using technologies such as packet switch, the bottleneck of two generations development can be broken through, realizes high-speed data service, and frequency spectrum profit can be improved
With rate, increase power system capacity.But FDD must use pairs of frequency, i.e., third generation business is provided in the bandwidth of every 2x5MHz.
Which can make full use of the frequency spectrum of uplink and downlink, but in asymmetrical packet switch (internet) work when supporting symmetrical service
When making, the availability of frequency spectrum then substantially reduce (due to low ascending load, the availability of frequency spectrum is caused to reduce about 40%), in this regard,
The advantage that tdd mode has FDD incomparable.
