litamin / ESP32-Cam Pixel Downsampling

Last active May 21, 2020 23:05

ESP32-Cam Pixel Downsampling - read out downsampled RGB pixels pretty pretty fast!

	// Code based on BITLUNI's ESP32-cam work

	// the size you want to downsample to
	int newWidth = 40;
	int newHeight = 30;
	int DSF = 160 / newWidth; // Down Sampling Factor - ideally DSF should be 4, 8 or 16.. so that the bitshifting happening below is accurate

	void downSample(unsigned char *frame)
	{
