摘要： Camera apparatus for use with an automotive vehicle having a rear view mirror. The rear view mirror comprises a half-mirror, light reflected therefrom being visible to an occupant of the vehicle. A lens is disposed adjacent to the half-mirror and receives light passing through the half-mirror. An image pickup device is optically coupled to the lens and receives light passing therethrough to form an image signal corresponding to the received light.

摘要： Transmission images are obtained by radiating X-rays having two different energy levels onto a subject in one direction, and then transformed into logarithmic images, respectively. From these logarithmic images, a contrast ratio due to the two kinds of X-rays having different energies is obtained. From this contrast ratio, the term relating to the thickness of the subject is eliminated, thereby providing information only relating to the quality of the material. By collating the information with the previously measured data of materials, the material of the subject is identified.
