An illumination apparatus for illuminating a target surface using light includes a light source that emits the light, a reflection integrator that forms plural secondary light sources using the light from the light source, and an optical unit that differentiates Helmholtz-Lagrange invariants in two orthogonal directions with respect to the light incident upon the reflection integrator.

The present invention aims to provide a variable-length coding apparatus that achieves a short processing cycle without causing an increase in circuit scale.Such a variable-length coding apparatus judges whether a VLC table has a variable-length code (VLC) corresponding to a combination (Last, Run, Level), by using an LMAX and an RMAX for the combination (Last, Run, Level). Based on the result of the judgment, the variable-length coding apparatus generates and outputs a code assigned to the comb...

The present invention relates to encoding apparatuses which allow encoding to be performed such that the occurrence of pre-echo and post-echo is suppressed. A predetermined waveform analysis is applied to a low-frequency-component input time-sequential signal which includes a high-frequency component occurring at a specific time, and a low-frequency-component time-sequential signal like that shown in FIG. 9A is generated according to a result of the analysis. The low-frequency-component time-seq...

It is an object of the present invention to provide a recording apparatus and a reproducing apparatus which change a picture compression rate depending upon a picture quality of a source which a user desires to retain, thereby a tape storage space being secured. A video-data compression rate N used by a 1:N video-data compression encoder 3 and a 1:N video-data compression decoder 6 is changed depending upon a picture quality set by a device 5 for setting a picture quality that a user desires. A ...

An optical apparatus is disclosed with which the correspondence between the movement of a movable lens and the position of an operating member can be maintained and the operability can be improved. The optical apparatus comprises a lens drive unit which drives a movable lens, an operating member operable within a predetermined movable range, and an operating member drive unit which drives the operating member within the predetermined movable range. The optical apparatus also comprises an operati...
