Title: Image recorder
IPC: G03G15/06
Filed: 1992-03-10
Abstract: PURPOSE:To make image density proper by altering the condition of development when the image density drops or rises although the concentration of toner is kept at almost a prescribed value. CONSTITUTION:When the reflection density (image density) of a standard toner image measured by an optical image density measuring means 61 drops/rises below/above a prescribed level, although the concentration of toner is kept at almost the prescribed value, a second CPU 60 controls a developing bias circuit 62 to alter a developing bias.

Inventor: ONO YOSHIHIRO
IPC: G01J3/50
Filed: 1991-04-19
Abstract: PURPOSE:To obtain a colorimeter wherein an error caused by deviation of spectral responsivity from color matching functions is subjected to self-correction, by a method wherein the mixture ratio of red, green and blue of a light to be measured is calculated and the spectral distribution of the light is synthesized on the basis of the mixture ratio and data on the spectral distribution of a representative color light. CONSTITUTION:A light 1 to be measured is a mixture light obtained by mixing lights of the three primary colors, red, green and blue, in an arbitrary ratio. A representative color light 2 is a color light of each color which is determined as the representative of an emission of each of the three primary colors, red, green and blue. A light-sensing unit 3 is composed of three light-sensing elements having spectral responsivity being approximate to color matching functions. It senses the color light from the light 1 to be measured or the representative color light 2, subjects it to photo-electric conversion, subjects an output signal of each light-sensing element to digital conversion and outputs it. The mixture ratio of the color lights constituting the light 1 to be measured can be determined from a measured value of chromaticity of the light 1 obtained by mixing red, green and blue arbitrarily and from measured values of tristimulus values of a source of the representative color light, by solving prescribed simultaneous equations, and the chromaticity of the light 1 to be measured is determined by synthesizing the spectral distribution of the light 1 to be measured on the basis of that mixture ratio and the data on the spectral distribution of the representative color light 2.

Filed: 1982-05-25
Abstract: PURPOSE:To obtain focus information on real-time basis by processing respective photoelectric conversion outputs of a photodetecting element array in the form of analog signals as they are. CONSTITUTION:The illuminance distribution of images formed on an odd-numbered photodetecting element group coincides with that of images formed on an even-numbered photodetecting element group in an in-focus state, and a time- series photoelectric conversion output is supplied to a BPF9. At this time, the most frequency components of the readout frequency (f) of the photodetecting element array 3 are obtained in the photoelectric conversion output at this time and the center frequency is not obtained in the output of the BPF9 of frequency f/2. When the images are not in focus, on the other hand, the illuminance distribution of the images projected on the ever-numbered photoelectric element group and that of images on the odd-numbered group have a lateral shift from each other, and the most components of f/2 are supplied to the BPF9.
