Ambarella solution:
Ambarella Chips from the United States, is a Chinese American company,
currently ambarella mainly have A2 / A5 / A7 series chips.
A2 are eliminated products, this series of chips have interview for eight years, four years into the mainland,china.
there are mainly A2S30, A2S60, A2S70;
there are mainly A2S30, A2S60, A2S70;
The A2S30 is 720p video resolution single function and low resolution belongs to Ambarella positioning in low order products,
mainly used in digital camera (DSC) camera (DV) DVR police law enforcement and other fields;
mainly used in digital camera (DSC) camera (DV) DVR police law enforcement and other fields;
A2S60 is based on A2S30 upgraded to 1080 p fullHD / 30 FPS video resolution;
Mainly used in DV ,car data recorder monitoring etc products.
A2S70 is Based on A2S60 upgraded to a 720 p / 60 FPS, 1080 p fullHD / 30 FPS video resolution.
A2S70 is mainly used in sports DV, aerial model, car data recorder, DV etc
Above A2 series chips in the market is mainly in the majority with A2S60/70
A5 chip series belong to the A2 and A7 excessive products and because of the specific function and
no obvious difference was found between A2, basic not recognized by the market, as shown in the following two series of specific differences;

Ambarella A5s camera chip using 528 MHZ ARM11 processor, supports full hd 1080 p 30fps h. 264 encoding, and integration of the professional processing 240 mpixel/s image processing functions.
Its image processing engine includes enhanced filtering noise reduction processing,
Its image processing engine includes enhanced filtering noise reduction processing,
image enhancement, as well as the innovation of the technology of electronic shake etc。
Ambarella A5 chip with A2 distinction: the Ambarella chip A5 is 2010 on the scheme,
every aspect to improve a lot, from 90 nm to 45 nm process, so the power consumption of small lot,
1080 p 30fps chips plus DDR just 1.1 W,Core ARM926 by ARM11 instead, frequency from more than 200 M to 500 M, so the performance also has a lot to ascend.
1080 p 30fps chips plus DDR just 1.1 W,Core ARM926 by ARM11 instead, frequency from more than 200 M to 500 M, so the performance also has a lot to ascend.
Algorithm on the DSP and the encoder has promoted, to improve the image quality, increase the 3 d noise reduction.
Ambarella A7L series Mid last year into the Chinese mainland last year, there are 30 d, 50 d, 30, 50, 55, 70 series chips
the Ambarella A7 cameras on the chip with 528 MHZ ARM11 processor, supports full hd 1080p 60fps or 4 m @ 30 p
(2560 x1600p30 current production of 30 FPS, video product only 3 m 2304 * 1296) h. 264 coding and integrates professional
(2560 x1600p30 current production of 30 FPS, video product only 3 m 2304 * 1296) h. 264 coding and integrates professional
can handle 500mpixel/s image processing unit. The A7 image processing technology used in
Ambarella famous image processing and noise reduction algorithm. Gradually add,
improvement of the image processing function to the unit, including electronic image stabilization technology

A7L series chips with (High Dynamic Range, HDR) function ensures that the image of High quality;
Under the environment of great light than shooting, due to the limited dynamic range of the ordinary camera,
can't record extremely bright or dark details. A photograph of the HDR procedures,
even in great light than shooting, whether highlights /a dark, are able to get better pictures than normal level;
Also has the WDR namely wide dynamic technology; Wide dynamic scenario is particularly bright and special dark parts of the site can see so clearly at the same time.
Also has the WDR namely wide dynamic technology; Wide dynamic scenario is particularly bright and special dark parts of the site can see so clearly at the same time.
Wide dynamic range is the brightness of the image can distinguish the brightest signal value and can distinguish the ratio of the dark light signal value;
A7LA30D / 50 d and A7LA30/50 difference is A7LA30D / 50 d built in 512 m DDR for chip production process limit yield is not high, the inconvenience
to mass produce, the cost is too high, this chip has been largely discontinued
Compared A7LA30 and A2 series in addition to the 528 MHZ ARM11 processor and WDR,
but does not support the 3 m tape, can with the cost of the whole machine A2S70 quite,
can also be interpreted as a large quantity of alternative A2 series products
A7LA50 increased on the basis of 30 2304 * 1296 30 FPS and lane departure warning but this function,
the original is still in debugging, so our company currently FK - N631 with leading vehicle FCWS,LDWS,FLWS is the latest technology at present
A7LA55 is on the basis of A7LA50 increase wi-fi chip other completely consistent, the WIFI function is mainly applied to the image of
auto black box to pass to the mobile phone or mobile phone directly preview,
the chip can also be used to customize the IP camera.
A7LA70 chip has the powerful features of the double record 1080 p 30 FPS,
has in a big order, but stability is still in continue to optimize;
Ambarella A9 4 k on the super high-definition camera chip can develop into the next generation of SLR,
sports, digital camera, the carrying forward of video camera, and
has outstanding quality of Static images quality. (noun explanation: 3840 * 2160,
4 k resolution is four times that of full HD 1920 * 1080 p, 9 times that of high-definition 1280 * 720, it is in the chip development debug
A9 not only support 4 k 30fps of high-definition video solutions, but also to a 1080 p 120fps, or 720 p 240fps of
high frame rate of video to capture fast moving in the scene.
A dual core ARM cortex A9 processor with its outstanding performance meet the
demand of advanced applications such as smart phone via wireless connection sharing video or image.
