1. An imaging apparatus, comprising: a lens, a half mirror, and a first CCD arranged along a same optical axis; and a second CCD arranged on an axis of light reflected from the half mirror, wherein the first CCD and the second CCD one have an inverse relationship in which one of the first and second CCDs outputs as an output signal a normal image of an input image input via the lens while the other CCD simultaneously outputs as an output signal an inverted image of the input image, the output signal of the one of the first and second CCDs representing a raster scan image of the input image from left to right and the output signal of the other CCD representing a raster scan image of the input image from right to left; and further comprising an image processor circuit for processing the output signals of the first and second CCDs based on their inverse relationship in order to perform image recognition.
