We report a single-chip CMOS NTSC video camera, incorporating a 306 × 244 image sensor array, sensor readout logic, A/D and D/A converters, and a custom 300-MIPS processor for color reconstruction and NTSC encoding. Operation is from a single 5-V supply and a 14.32-MHz crystal clock. Implementation is in 0.8-μ single-poly-double-metal (SPDM) CMOS, integrating some 580 000 devices on a 68-mm 2 die. A related dual-standard PAL/NTSC coprocessor is also described, extending the architectural basis of the single-chip device whilst incorporating more complex signal-processing function. In this case, implementation is in 0.6-μm SPDM CMOS, integrating some 285 000 devices on a 27-mm 2 die.
