A differential pressure sensor includes a measuring mechanism having a chamber on the high-pressure side that is sealed by a first dividing membrane, and a chamber 6 on the low-pressure side that is sealed by a second dividing membrane. The emissive construct includes a fluorescent emissive layer, a partial hole-blocking layer, and a phosphorescent emissive. If the current region in the deblocking filtering process is at a boundary of the current region in the adaptive offset process, the deblocking filter control unit supplies control information for increasing the filtering strength to a deblocking filter.
