ABSTRACT:
In a picture data reproducing apparatus, a data dropout from a disc such as a CD-DA can be avoided. In a still picture data reproducing apparatus for reproducing a recording medium on which both of still picture data having at least variable data length, and data length information corresponding to the still picture data have been recorded, this reproducing apparatus is characterized by including: a reader for reading out both of the still picture data and the data length information corresponding to the still picture data from the recording medium; a decoder for decoding the still picture data and also the data length information corresponding to the still picture data, which are read out by the reader; a counter for counting a data length of the still picture data decoded by the decoder; a comparator for comparing the data length information decoded by the decoder with the data length counted by the counter; and a controller for making such a judgement that the data is dropped out by way of the comparator when the data length information decoded by the decoder is not coincident with the data length of the still picture data counted by the counter, and for controlling the reader to again read out the same still image data.
