Abstract
Monolithic circuit chips are disclosed which are particularly adapted for use with barcode reading, video and photographic systems. The monolithic circuit chip can include a sensor array, digitizer and decoder. The monolithic circuit chip can alternatively include an imager circuit, radio frequency circuit and memory. The memory can be one of ferroelectric random access memory (FRAM), E2PROM, or Flash memory. The monolithic circuit chip can be formed using complementary metal oxide semiconductor (CMOS) techniques.
Claims18
A monolithic circuit chip for use in an imaging optical code reading device having a radio frequency (RF) communication capability, wherein the circuit chip comprises:
- a complementary metal oxide semiconductor (CMOS) imager;
- CMOS microprocessing circuits for receiving image data from the CMOS imager and data from an RF receiver;
- and
- a memory for providing non volatile data storage on the circuit chip.
A monolithic circuit chip comprising:
- a sensor array;
- a digitizer for digitizing the captured images;
- and
- decoder for decoding the digitized images.
A method for communicating image information using a monolithic circuit chip comprising the steps of:
- capturing, by a digital imager, an image;
- processing the image by a processor using a ferroelectric memory;
- and
- transmitting, by a radio frequency transmitter, the processed image over an air-interface, wherein the digital imager, processor and radio frequency transmitter are formed on the monolithic circuit chip.
