I use 640*480 15pts for preview but 2048*1536 15pts(i have written wrong for this framerate in the answer). I check in the logcat and console print. The ov3640 has two work mode: one is QXGA mode for full pixel and 15 framerate, the other is XGA mode for 1048*768 and 30 framerate. I only use QXGA mode for preview and capture, in order to avoid mode switch. I just set the register of crop, zoom and output size for the resolution mode changement. Is this correct?</P></BODY></HTML> Wed, 09 Sep 2015 02:19:35 GMT https://community.nxp.com/t5/i-MX-Processors/iMX6Q-Android-4-4-3-use-ov3640-image-Grid-problem/m-p/430438#M65461 caritzhu 2015-09-09T02:19:35Z
