Abstract:
PROBLEM TO BE SOLVED: To form a color image excellent in color reproducibility by accurately measuring the color of each of color images without depending on the reflection factor of each color image and by correctly detecting the hue and density of the color image to be detected. SOLUTION: When reflected light from the color image is detected by emitting light from a white LED 103, an amount of light beams is detected by photo diodes 101R, 101G, and 101B by changing color measurement conditions in accordance with reflection factors estimated by the forming conditions of the corresponding color images to be detected. The image forming conditions are adjusted based upon the amount of reflected light beams from the thus detected color images. COPYRIGHT: (C)2004,JPO&NCIPI
Abstract:
A specific reflection area (42) on a paper surface (37a) is irradiated with light from a light source (41) via or not via a lens (43). A photoelectric conversion element (44) is placed on a focal surface in the rearward of the lens (43) and out of the light reflected (including scattering light and diffusion light) from the reflection area (42) on the paper surface (37a), only the whole light reflected within a predetermined angular range is received by the photoelectric conversion element (44) via the lens (43). The density of the image formed on the paper surface (37a) is measured from the light reception output. When the paper surface (37a) is irradiated with light from the light source (41) via the lens (43), the light source (41) is placed backward from the focal surface (43b) in the rearward of the lens (43).
Abstract:
PURPOSE:To increase the quantities of light of weak light sources which differ in light emission wavelength alternately in inverse proportion to the light emission quantities of the respective light sources, and to take a precise color measurement regardless of the ruggedness and luster of an object, by arranging elements over a measurement surface successively along a parallel circle and photodetecting reflected light. CONSTITUTION:Light emitting elements 1-3 of R, G, and B are arranged successively over the measurement surface 6 along the circle in a parallel plane, and the same point on the measurement surface 6 is irradiated. Light which is projected at 45 deg. and photodetected at 0 deg. is condensed by a lens 4 and photodetected by a photodetecting element 5. The number of elements are decreased because of brightness 2-10 tims as great as those of light emitting elements 1-3, and the number of elements 3 of B is decreased; they are arranged symmetrically. A microcomputer 7 sends lighting timing pulses for (n) times to an LED driver 8 to turn on the light emitting elements 1-3 of R, G, and B in time series. A reflection value by disturbing light when the elements are turned off and data when they are turned on are A/D-converted and inputted to the microcomputer 7 to obtain an addition mean for (n) times. The microcomputer 7 performs calculations based upon the both to obtain signal light, finding values of R, G, and B.
