Video Input Port 720p sensor configuration

Intellectual 380 points

Hi all,

 

I’m working on VISION_SDK and configuring a AR0101 720p camera. I tried many possible configs in visionsdk capture parameters, but get error images or no image.

 

Main difference between AR101 and OV10635 is AR101’s vsync is not a pulse. I’ve tried changing pInstPrm->videoIfMode, but it doesn’t work properly. Using ov10635’s configuration, I dump the image just in the attachement. It seems that each line start at different point, and some line is completely wrong, many lines at the bottom are cropped. Software reset the sensor may lead to different images with little difference.

 

I have tried config such as:

  1. Inverse vsync polarity.  No effect(same as 10635 config).

  2. Line_capture_style_hsync.   No effect.

  3. VIFM_SCH_DS_AVID_VSYNC.   No Capture.

OV10635

 

Please give any advice on visionsdk capturelink config. Attachment is the dump from display in 1280x720 YUV420.

Same config may display different images after sensor is reset. Both images are dump from ddr.
