Electronic handheld unit i.e. stereometer, for determining stereoscopic parameter during operation, has input keyboard and display for outputting stereoscopic relevant distance values

摘要

The unit has an input keyboard and a display for outputting stereoscopic relevant distance values. An embedded laser-, infrared or ultrasonic based telemeter provides stereoscopic near- and far points and the distance values so that an electronic circuit independently calculates stereo basis and convergence values. The calculated values are transmitted to a camera by wireless transmission e.g. Bluetoothor wireless local area network (WLAN). A color temperature measuring device and the telemeter are integrated in a combination apparatus with a light meter.
