OV2640 jpeg image with pixelated edges

Open JPMJPM opened this issue 6 years ago • 2 comments

Hi,

I have developed a OV2640 camera JPEG streaming solution with :

  • Over Ethernet.
  • Only two I2S 2.800 32 bits words buffers (ring buffer).
  • There is not frame buffer.
  • 50 FPS.
  • SVGA.

Everything seem to be OK but the image edges are pixelated. Can anyone tell me what may be happening ?. I attach TXT (C) and JPEG files.

Thanks in advanced and regards.

Can you please tell me which board did you use ? and the connection with your camera ?

I used a ESP32-WROOM module on a custom board.

The connection between ESP32 module and camera is in the source code file.
