Filed: 1994-07-28
Abstract: PURPOSE:To obtain color optical parts with high reproducibility of color tones/ densities and to increase stability without adhesion of dust, etc., on lens surfaces and without defects, such as unequal color and color drop-out by subjecting a base material to irradiation with radiation energy to irradiate the base material with radiation heat in vacuum after applying dyes on the base material surface. CONSTITUTION:This apparatus for production consists of a heating means 1 for heating the optical parts, a heat shielding member 2 installed between this heating means 1 and the optical parts, a heat shielding member 2 and/or moving means for moving the optical parts as well as a vacuum chamber 4 enclosing these means and a discharge port 6 for evacuating the inside of this vacuum chamber 4 to a vacuum. As a result, the dye concn., heating temp. and time are controlled at the time of coloring the optical parts by using the dyes and, therefore, the color tones and densities which are unstable heretofore are stably obtd. There is no adhesion of dust, etc., on the lens surfaces at the dyeing is executed in the vacuum and, therefore, the problems, such as color drop-out, occurring therein do not arise any more.

Title: Picture coding device
Inventor: INOUE IKUO
IPC: H04N1/415
Filed: 1985-08-13
Abstract: PURPOSE:To reduce the number of codes without deteriorating picture quality by replacing a part of pattern information with the information of the order in coding gradation information. CONSTITUTION:A gradation separating section 104 expresses gradation information in a block with two gradations representing the block and generates the pattern information to represent a picture element corresponding to each gradation. The gradation information a0, a1 are stored in a gradation information storage section 105 and pattern information phii representing the corresponding between the two gradations and picture elements obtained in this way is stored in a pattern information storage section 106 as a 16-bit data. A gradation information coding order deciding section 107 uses a value phi16 of the least significant bit of the pattern information to apply coding in the order of a0, a1 when phi16=phi and in the order of a1, a0 when phi16=1. Since a brightness in the block is a binary value, the value phi16 is sent as it is to a code generating section 108. The code generating section 108 uses the transfer data a0, a1, phii from the gradation information storage section 105, the pattern information storage section 106 and the gradation information coding order deciding section 107.
