  • Patent number: 7630103
    Abstract: When a monochromatic mode is set, a CPU outputs a SW signal and executes a control to input an output from a monochromatic reading line sensor to a CCD signal processing section. Then, after a black level adjustment period ends and a black reference level reaches a desired value, the CPU starts reading of a black reference signal for shading correction. When a color mode is set, the CPU outputs a SW signal and executes a control to input an output from a color reading line sensor to the CCD signal processing section. After the black level adjustment period ends and the black reference level reaches a desired value, the CPU starts reading of a black reference signal for shading correction.

    Abstract: A four-line CCD sensor is structured by line sensors R, G, B in which color filters are respectively disposed on surfaces of light receiving elements, and a line sensor BK at which no color filter is disposed. Amplitudes of signals which are outputted from the line sensors R, G, B at a time of reading a color document, and an amplitude of a signal which is outputted from the line sensor BK at a time of reading a monochrome document are adjusted so as to be substantially equal to one another. In a case in which a color document is read, outputs of the line sensors R, G, B are selectively provided, and in a case in which a monochrome document is read, output of the line sensor BK is selectively provided.
