Patent JP-H03295669-A (JP)
Title: Recorder
Inventor: KUMADA SHUICHI
IPC: G09G5/00
Filed: 1990-04-12
Abstract: PURPOSE:To simply obtain a desired color tone output by forming an image from sample of coded color information on a recording medium based on input predetermined coded pattern information and the color information. CONSTITUTION:When a mode is selected and it is judged not to be a sample output mode, it is transferred to a normal processing mode. On the other hand, in the case of the sample output mode, a sample is output. Here, the mode is selected by an operation unit of a host computer or an operation panel 24 of a recorder 2. Since the sample output indicates an index number, registration color solidly coating a predetermined region and color component data of the registration color, an operator can confirm whether desired color is obtained or not by the sample. If the desired color is not obtained, the registration color is altered. When the registration color is altered, the index number and the color component data are input from the unit of the host computer, thereby altering the registration color. Thus, matching properties of the color output by a recorder to the color on a display can be simply confirmed.

IPC: G01J1/44
Filed: 1978-08-12
Abstract: PURPOSE:To establish the photo signal observation unit which can accurately measure the light level and modulation, by eliminating the drift due to dark current when light is not incident to the photo detection element. CONSTITUTION:When no light 2 is incident to the photo detector 11, the switch 30 in ON. The loop from the output terminal 23 of the amplifier 20 to the resistor 31, switch 30 and input terminal 22 forms negative feedback in this case. Thus, the voltage across the resistor 13 with the dark current of the photo detector 11 and the offset voltage of the amplifier 14 are amplified 14 and appeared at the output terminal 17 and fed to the input terminal 21 of the amplifier 20. This voltage is amplified 20 together with the offset voltage of the amplifier 20, but the voltage appeared at the output terminal 23 is negative-fed back to the input terminal 22 of the amplifier 20. This voltage is the voltage equal to the sum of the voltage fed to other input terminal 21 of the amplifier 20 and the offset voltage of the amplifier 20 and it is not almost appeared at the output terminal 23. That is, the drift due to the dark current and the offset voltage of the amplifiers 14 and 20 can be cancelled.

The respective vertexes An are displaced in three dimensions at random with random numbers and a wrinkled plane is formed of the deformed triangles (S44 and S45). For the wrinkled plane, luminance calculation is performed in consideration of a given assumed light source to find luminance at each part (S46). The texture image is inputted to the UV coordinate system (S47) and texture mapping considering the luminance is performed (S48) by using the texture coordinate values (u, v) of the respective vertexes An on the wrinkled plane as a clue.  The wrinkled plane after the texture is mapped is projected on the XY plane to obtain and print two-dimensional image data (S49).
