A method of encoding and decoding image data by applying an image capturing device includes generating a difference coding group, applying an modified Hadamard transform (MHT) on the difference coding group to generate a corresponding low-frequency parameter and a plurality of corresponding high-frequency parameters, adjusting the low-frequency parameter, adjusting the high-frequency parameters by a quantification factor, decoding the low-frequency parameter, decoding the high-frequency parameters by the quantification factor, and applying an inverse modified Hadamard transform (IMHT) on the low-frequency parameter and the high-frequency parameters to decode the difference coding group.
