The Cinematography Electronics CINETAPE MEASURE system enables fast distance measurement. This ultrasonic system continuously calculates the distance between a subject and the camera’s film-plane. By continuously measuring distance during a shot, small or subtle subject movements are not a problem. With non-stop measurements, focusing a camera lens is simplified. This saves time, avoids retakes and reduces production costs.
The main components are the CINETAPE MEASURE CONTROL and the SENSOR ASSEMBLY. The control displays accurate distance measurements. This comes from the sensors constant stream of data.
Our CINETAPE MEASURE System is small, rugged, lightweight, and quiet. The ultrasonic range finder is compatible with all lenses, film cameras and video cameras. In addition, our system is easy to set up and use, making it the first choice of professional filmmakers.
CineTape Measure Control
The stylish Cinematography Electronics CINETAPE MEASURE CONTROL is the brain of the system. It continuously computes the distance between the camera’s film plane and the subject. A simple one-time Film-Plane offset adjustment programs the relationship of the film plane to the sensor position. When the control detects a subject, the green Sense LED glows. Then calculated distance displays on the LED display. This is in either feet-inches or meters-centimeters. Adjustable brightness levels for the large red LED display offers comfortable viewing under different lighting conditions. The digital Sensitivity adjustment feature fine-tunes the system range, which is also helpful with different subject reflectivity. Finally, the Close Focus feature sets the minimum sense distance. The sensor disregards objects within this area. All functions are set and stored digitally. This safeguards against accidental changes and provides accurate repeatability between units.
The Cinematography Electronics SENSOR ASSEMBLY consists of two small cone-shaped “horns”. Also a miniature pan tilt mechanism, a mounting stud, and an electrical connector. The horns send and receive ultrasonic signals. Thus enabling the distance measurement calculation. Mounting the SENSOR ASSEMBLY onto a camera package is simple with the combo stud. With its pan and tilt adjust/lock knobs, aiming the horns towards the subject is quick and straightforward. The SENSOR ASSEMBLY interfaces to the control via a short detachable Sensor Cable. Finally, a spring-loaded holder permits the attachment of laser pens. These provide a visual reference during calibration.
