首先,很多车友关注过行车记录仪主控芯片“联咏NT96650”对这个芯片一定熟悉不过,市面上性价比产品,但对安霸A7LA70芯片是否了解?
美国安霸A7系列是多功能1080p60 DV/DSC相机解决方案,A7系列能拍摄高达4Mp 30帧(2560x1600p30)影片与H.264 codec的高阶单芯片,更是Full HD1080p60多功能DV/DSC相机的解决方案。1080p60fps影像解码、编辑、显示等技术环境已成熟。
A7让一般消费者也能利用1080p60的技术,自行创作令人惊艳的高画质影片(UGC)。
安霸A7 H.264 Codec单芯片整合了能处理500Mpixel/s的影像处理技术(image sensor pipeline)、1920x1080p 60fps或4M@30fps (2560x1600p 30fps)的H.264 Codec与528 MHz ARM11处理器。
A7的影像处理技术展现了安霸卓越的图像与噪声滤波算法,包括更紧密整合的电子防手震(EIS)功能。
A7搭配有硬件设计参考架构、软件开发套件与完整的DV/DSC相机软件应用程序,是Full HD1080p 60fps 多功能DV/DSC相机的解决方案。
搭载安霸A7LA70行车记录仪,它是目前市场上最好的行车记录仪,国外市场价在300美元左右,1080P 60帧,码率24MB,而且还是浮动码率,
今天自己买到一款安霸A7LA70行车记录仪,非常兴奋,随手录制一段视频,1080P 60帧视频画面非常顺畅,在机器上看画面也是非常流畅,没有半点卡顿,感觉机器的反应速度很快,难怪有CPU支持就是不同,它达到528MHz ARM11处理器。
安霸A7的性能众所周知,你拥有了一颗强劲的心,还要有刚铁之躯配套才行,其它也要好的材质,例如镜头、图像传感器CMOS sensor 还有其它零配件,较好的软件研发团队,也是非常关键的要素-------即使相同的安霸芯片,在不同的镜头和软件的条件下,所达到的效果依然可以相差很远~~很远~~~~相当的远!!!

Currently, there are several models of Anba A7 on the market (prices range from low to high) :
Part Number    resolution
A7S30: 1920*1080P 30 frames.
A7LA50D/ A7LA55: 2304 *1296P 30 frames.
A7LA70/A7LA70D: 1920*1080P 60 frames.
A7la75: 2560 *1440 30 frames
 
First of all, many car friends have paid attention to the main chip of dashcam, "Lian Yong NT96650". They must be familiar with this chip, but do they know about the A7LA70 chip on the market?
 
Ambarella A7 series is a multi-function 1080p60 DV/DSC camera solution. The A7 series can shoot up to 4Mp 30 frames (2560x1600p30) film and h.264 CODEC high-order chip. It is also a solution for Full HD1080p60 multi-function DV/DSC camera.1080P60FPS image decoding, editing, display and other technical environment has been mature.
 
The A7 gives the average consumer the ability to create amazing, high quality (UGC) videos by themselves using 1080p60 technology.
Ambarella A7 H.264 Codec single chip integrates image sensor pipeline, 1920x1080p 60FPS or 4m@30FPS (2560x1600p 30Fps) and 528mhz ARM11 processor, which can handle 500Mpixel/s.
 
The A7's image processing technology demonstrates Anbar's superior image and noise filtering algorithms, including a more tightly integrated ELECTRONIC Hand shock (EIS) capability.
 
With hardware design reference architecture, software development suite and a complete DV/DSC camera software application, A7 is the solution for Full HD1080p 60FPS multi-functional DV/DSC camera.
 
It is equipped with Anba A7LA70 dashcam, which is the best dashcam on the market at present. Its price in foreign market is around $300, 1080P 60 frames, the code rate is 24MB, and it is also a floating code rate.
 
Today I bought an AMba A7LA70 auto data recorder. I was very excited and recorded a video at random. The video screen of 1080P 60 frames was very smooth, and the screen was also very smooth when viewed on the machine without any delay.
 
Ambarella A7 performance is well known, you have a strong heart, have just iron body kit, the other is good material, such as lens, image sensor, CMOS sensor and other components, better software research and development team, is also very critical elements -- -- -- -- -- -- -- even if the same chip in the Ambarella, under the condition of different lenses and software, achieved the effect can still far far away ~ ~ ~ ~ ~ ~ very far!!!!!!
