DATASHEET – epc660

3D TOF Imager 320 x 240 Pixel

General Description

The epc660 is a fully integrated 3D-TOF imager with a resolution of

320 x 240 pixels (QVGA). It is a highly integrated system-on-chip

camera system. Apart from the actual CCD pixel-field, it includes

the complete control logic to operate the device. Data communica-

tion is done through a high-speed digital 12-bit parallel video inter-

face.

Even for mobile devices, only a few additional components are

needed to integrate 3D camera capability. Depending on the sys-

tem design, a resolution in the millimeter range for measurements

up to 100 meters is feasible. 65 full frame TOF images are deliv-

ered in maximal configuration. By using the advanced operation

modes, this can be boosted up to more than 1000 TOF images per

second! The high degree of integration lays base for straight-for-

ward camera system design with minimal part count. The extreme-

ly high sensitivity of the optical front end allows for a reduced illumi-

nation subsystem and reduces the power consumption of the over-

all system significantly.

An evaluation kit with hard- and software examples and a compre-

hensive manual helps the system designer to speed up system in-

tegration.
