Abstract: A 3D display device that includes: a first optical section of focal distance f1 provided with a group of small lenses arrayed along a specific direction; and a second optical section of focal distance f2 that converges N beams of parallel light that are emitted from the first optical section and hit the individual small lenses by converging so as to offset the N beams from an optical axis. A distance d1 between the first optical section and the second optical section satisfies f2−f1≦d1≦f2 and a viewing distance d2 from the second optical section satisfies d2≈f2.

Abstract: A prediction error generating unit generates a predictive vector from the motion vectors of a plurality of adjacent blocks, and obtains a difference from a target vector. A plurality of variable-length coding units respectively encode the output of the prediction error generating unit with different encoding methods. A determining unit estimates the accuracy of the predictive vector generated by the prediction error generating unit based on the degrees of non-uniformity of the motion vectors of the plurality of adjacent blocks. A selecting unit selects one of the encoding results obtained by the plurality of variable-length coding units.
