Light Mode, Saturation, Contrast and Brightness Example

[Lucho1976]

Hi i have an Arducam ESP8266 with OV2640 and i want to try the diferents light Mode, saturation, contrast and brigthness.

I found this document with examples like below and i saw than i must write them with myCAM.wrSensorReg8_8() function, is that correct ?. Can i make a program wich a delate between modes and capture a file picture to see the diferences?. Ideal i would be some interface program like html wich sent parameters, is there something like that?.

Thanks....

@Lucho1976 Hi,

Yes, if you want to change the light mode, you should set the mode by using myCAM.wrSensorReg8_8(). If you want to send the image data to the html, you can refer to https://github.com/ArduCAM/ArduCAM_ESP8266_UNO/tree/master/libraries/ArduCAM/examples/ESP8266/ArduCAM_ESP8266_Capture

I'm trying to do the same thing. In my cam setup, I do something like this.

  #if defined (OV2640_MINI_2MP) || defined (OV2640_CAM)
    //Check if the camera module type is OV2640
    myCAM.wrSensorReg8_8(0xff, 0x00);
    myCAM.wrSensorReg8_8(0xc7, 0x00);  //AWB on
    myCAM.rdSensorReg8_8(OV2640_CHIPID_HIGH, &vid);
    myCAM.rdSensorReg8_8(OV2640_CHIPID_LOW, &pid);
  #endif

But my images still look really dim and green in ambient, low-light. Any suggestions?

@adjavaherian Hi, We have update our library to add ArduCAM_Mini_2MP_OV2640_functions.ino demo. Please refer to this link to learn more about the OV2640 functions. https://github.com/ArduCAM/Arduino/blob/master/ArduCAM/examples/mini/ArduCAM_Mini_2MP_OV2640_functions/ArduCAM_Mini_2MP_OV2640_functions.ino

Let us know if you need more help. Regards, ArduCAM support team.

Thanks Lee, I'll give it a shot!

You updated the example to support brightness and other functions, but never updated this repository (ArduCAM_ESP8266_UNO) to a version of the library that has the required function calls (OV2640_set_Brightness(), etc...).

As it is, if you're using the ESP version of the arducam library, those examples are useless.

@fake-name Hi,

Thank you for your advice, we will update it. You can just copy the ArduCAM.cpp and ArduCAM.h files to your ESP8266 UNO library and replace the old files.

Maybe respond to https://github.com/ArduCAM/ArduCAM_ESP8266_UNO/issues/19 ?
