the output of RGB888 data

[Dwight-Choi]

Hi, thank you for your codes and explanation. It really helps for me to understand how to control ESP32-CAM.
Currently, I want to get raw data of 240*320 or little higher resolution images(preventing psram issue) for image processing.
So I tested with your code to get RGB888 data and sucess to get the rgb file.
But,

1. I couldn't open the file because it looks like broken. Could you give me idea to handle this file?
2. Is there any method to get the real raw data file from camera sensor(OV2640) with ESP32-CAM?
   Thank you in advance for your help.

Hi,

I have a Processing sketch here which will take the rgb file and display it
https://github.com/alanesq/esp32cam-demo/blob/master/Misc/displayRGB.pde

The file is not a standard image file but just the raw RGB data (3 bytes per pixel) so you will not be able to load it in to a standard image viewer etc.

Thank you for kind reply.
I understand what you said and I've tried transform these 1 dimension array to 3 dimension(RGB channel) and display it.

So, do you have any idea to get raw data from camera sensor? or is there any mode to get that in this program?
