| Zusammenfassung: | The present technology relates to a data processing apparatus, data processing method, and a program which improve a compression ratio. Provided are a first compression part compressing data using compressed sensing and a second compression part compressing observation coefficients coming from the first compression part using a method different from the method used in the first compression part. The first compression part performs random sampling using a sampling matrix optimized for compression by the second compression part. The sampling matrix is designed to minimize the differential value between the observation coefficients. The present technology can be applied to recording/reproducing apparatuses that capture, compress, record, and reproduce image data. |
