Abstract: Disclosed are an image encoding method using a skip mode and a device using the method. The image encoding method may comprise the steps of: judging whether there is residual block data of a prediction target block on the basis of predetermined data indicating whether residual block data has been encoded; and, if there is residual block data, restoring the prediction target block on the basis of the residual block data and an intra-screen predictive value of the prediction target block. Consequently, encoding and decoding efficiency can be increased by carrying out the encoding and decoding of screen residual data only for prediction target blocks where there is a need for a residual data block in accordance with screen similarity.

Abstract: Disclosed is an apparatus for identifying authenticity of a holographic image, which is capable of identifying the authenticity by comparing a holographic image reconstructed by irradiating light having the same characteristic as an irradiation characteristic of a first reference beam used in generating the holographic image with an original image. Accordingly, since an image or a pattern is recorded by using a reference beam having a specific angle and a specific laser wavelength band in making a hologram, replication or copying for forgery is prevented from being easy.
