摘要:
The present disclosure discloses an apparatus and method for compressing coefficient values of a compensation equation for compensating for a defect in an image and a circuit for compensating for display data using compression values compressed by the apparatus and method. The apparatus for compressing coefficient values of a compensation equation includes a coefficient value provision unit configured to provide coefficient values of a coefficient of a compensation equation for compensating for a defect in an image and location information for each pixel and a coefficient value compression unit configured to provide a first compression bitmap and a second compression bitmap by sequentially performing first compression and second compression on the coefficient value.
