Abstract: An image haze removing apparatus includes at least a transmission coefficient generator, a low pass filter, a particle size parameter estimator, a transmission coefficient divider and a real image estimator. The transmission coefficient generator generates a transmission coefficient based on a captured image. The low pass filter outputs a low frequency image, which includes a low frequency component of the captured image. The particle size parameter estimator estimates a particle size parameter based on the low frequency image. The transmission coefficient divider divides the transmission coefficient based on the particle size parameter to generate first to third divided transmission coefficients, which correspond to red, green and blue data of the captured image, respectively. The real image estimator estimates a real image by applying the first to third divided transmission coefficients to the red, green and blue data of the captured image, respectively.
