1. Imaging apparatus for generating a lower resolution verification image signal from a higher resolution image source, said imaging apparatus comprising:

  • an area image sensor having a plurality of light-sensitive areas arranged two-dimensionally in parallel lines each oriented lengthwise in the horizontal high speed scanning direction;

    a color filter array having a pattern of at least one line of same-color luminance filter elements oriented in the horizontal scanning direction adjacent to at least one line of chrominance filter elements including at least one other color oriented in the horizontal scanning direction;

    means for scanning said image sensor and generating an output signal comprising a plurality of discrete image signals corresponding to the plurality of light-sensitive areas, said output signal comprising a line-separated pattern of luminance image signals and chrominance image signals; and

    means for generating a low resolution verification image signal from all or a portion of the luminance signals from said lines of same-color luminance filter elements.
