Function Documentation

calc_brightness()

float calc_brightness	(	uint8_t *	img,
		int	size
	)

calculate brightness as the average pixel val

Parameters

img	pointer to img
size	size of the image

Returns

average (float)

deflicker()

bool deflicker	(	uint8_t *	img,

		int	h
	)

perform deflickering

Parameters

img	uint8 pointer to image
w	width
h	height

Returns

true if deflickering else return false (not enough image queued)

get_factor()

(

)

calculate brightness ratio related to previous brightness

Returns

ratio (float)
