Abstract: PURPOSE:To provide a camera with speed measuring function appropriate for the control of the violation of the speed law. CONSTITUTION:A laser transmitter 4 emits pulse laser beams of constant intervals, for instance. The emitted laser beams pass beam splitters 3, 2 and are emitted outside from an objective lens 1. The laser beams reflected by an object enters inside coaxially from the objective lens 1 and reaches the beam splitter 2 so as to be branched into transmitted light and reflected light there. The transmitted light is reflected by the beam splitter 3 and enters a receiver 5 so as to be subjected to electric conversion and inputted into a signal processing part 6. The signal processing part 6 measures time difference between a transmit signal and receive signal to compute the distance to the object, and also obtains the distance information at the time of two points or more corresponding to pulse intervals to compute the speed. An image pickup part 8 acquires the image data of the object from the reflected light at the beam splitter 2. The obtained speed data and image data are recorded-stored in the floppy disc of a recording part 7. Each element is simple and integrally assembled so as to realize a compact portable camera with speed measuring function.
