The embodiment of the invention discloses a method for processing transformation coefficients and a device. The method comprises the steps that the transformation coefficients of a current transformation block are obtained after transformation and quantification; the transformation coefficients needing to be reset in the transformation coefficients of the current transformation block are determined; the determined transformation coefficients needing to be reset are reset sequentially according to a preset scanning sequence to obtain the processed current transformation block; entropy coding is carried out on the processed current transformation block. According to the scheme, some abnormal noise interference can be restrained, and therefore subjective experience is improved.
