IPC: H04N1/60
Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To allow the user in an observed environment to simply perceive an image nearly coincident with an image perceived in an optional input environment with high accuracy. SOLUTION: RGB image data of an image displayed on a CRT system (display device A) in a reference environment (dark room environment) are converted into image data in a CIELAB value by using a characteristic value of the CRT system (display device A) (steps 100-104) to generate a CIELAB image in an observed environment (bright room environment) (106). The CIELAB image corrected in the observed environment is obtained by using the characteristic value in the observed environment (bright room environment) (108-112). The image data depending on the CIELAB value are converted into the RGB image data by using the characteristic value of the CRT system (display device B) and outputted (114-118).  Thus, an image nearly coincident with the image perceived as an image in a desired color displayed on a screen of the CRT system in the dark room environment is displayed on a screen of the CRT system in the dark room environment.

Title: Printing material and production thereof
Inventor: ODAKA TSUNEICHI
IPC: H01L21/66
Filed: 1984-11-09
Abstract: PURPOSE:To contrive secure, easy and inexpensive correction of a printed part, by a method wherein the entire printing region is irradiated with laser light to eliminate a marked part, then a printing material is coated with the same material as the raw material of the printing material, and printing is newly conducted by laser marking. CONSTITUTION:To eliminate a laser-marked part 3 in the surface of a package 2 of a semiconductor device 1, the entire part of a printing surface 12 of the package 2 is irradiated with laser light 4 to remove a surface part, thereby eliminating the marked part 3 in the surface of the package 2. In irradiation with the laser light 4, since the package 2 part at the marked part 3 has been denatured by heat at the time of laser marking and has not been subjected to any processing after molding, the part is melted more easily than other surface parts which are neither denatured nor strained. Accordingly, the laser irradiation results in that the marked part 3 can not be distinguished from the surrounding part, namely, the marked part 3 is eliminated without leaving any trace.
