不小心买到一个艾科创新的芯片arkmicro (ark3188)的,在win下不用装驱动。在linux下搞不定,下面是一些信息:
$ lsusb
Bus 001 Device 003: ID 18ec:3188
(只有号没有名字)
~$ lshal -u usb_device_18ec_3188_noserial

ARK3188
Time : 2006-10-25
General Description
The ARK3188 is a single-chip PC camera DSP complied with high speed USB2.0, interfaces with the resolution of CIF/VGA/SXGA image sensors in a LQFP48 package for normal application. The ARK3188 combines USB2.0 transfer functions, image signal procession, image compression and the sensor interface. Thanks to the advanced functions,the ARK3188 provides PC Camera with a high cost-effective solution.
Features
• USB Module
Complied with USB specification version 2.0 for high-speed (480Mbps) and full-speed (12Mbps) USB
Support video data transfer in USB isochronous
Complied with USB Video Class Version 1.1
• Sensor Module
8 Bit CMOS image raw data input
Support VGA/1.3M CMOS sensor, such as Hynix 7131R, Omni Vision OV7670, Micron MT9v011/MT9v111, PixelPlus PO3030… etc
Up to 30fps@VGA or 10 ~ 15fps@1.3M for PC mode video
Provide individual R/G/B digital color gains control
• Image Processing Module
Provide snapshot function
Embedded AE calculation and report
Built-in gamma correction and auto white balance gain circuit
Embedded high performance color processor
JPEG baseline capability of compression encode
No external memory needed
2009.6.9这个driver已经被uvcvideo提供了。
但是还没有进入mainline。。。所以你需要2.6.31rc1以上的内核。。。
昨天晚上我刚弄好。。。。但是由于skype不支持rgb摄像头,于是skype也不能用。。。
由于未知原因mercury也不能用。
amsn和ekiga还有cheese都完全正常工作。 |
