Terminology around camera sensor interface module is confusing. MIPI CSI is supposed to be a camera serial interface. Cameras on Pinephone are connected via a 8-bit parallel interface.
I'm also not sure how they came up with 5Mpix in the datasheet, CSI can do up to 4800x4800 which is 23Mpix.
OTOH, 1080p@30fps is not attainable on the parallel interface, at least not with the cameras that are in the phone. It would require ~120MHz clock, and communication starts to break down at around 60-70MHz.
- amosbatto 6y agoLooking at the pin description on page 24 of the A64 Datasheet, it looks like the 8 data pins (CSI_D0 … CSI_D7) are for a MIPI Camera Parallel Interface (CPI), but Allwinner is calling it "CSI" (MIPI Camera Serial Interface). This is really confusing, but I am simply repeating what the A64 docs say. Out of curiosity, what is the highest-resolution still photo anyone has taken so far on the PinePhone? Maybe I should list that in the table. Is 1080p@15fps the best video anyone has managed so far with the PinePhone?
- megous 6y agoIt's possible to do 1080p@20fps max. I tried a few days ago. Recordings from the phone: 1080p@20fps: https://megous.com/dl/tmp/vid.mp4 https://megous.com/dl/tmp/vid.mp4 720p@30fps: https://megous.com/dl/tmp/vid-720.mp4 https://megous.com/dl/tmp/vid-720.mp4 Cam -> display latency test (50ms): 720x480@60fps is also possible: https://megous.com/dl/tmp/IMG_0375.MOV https://megous.com/dl/tmp/IMG_0375.MOV
