CMOS image sensor with testing circuit for verifying operation thereof |
摘要 |
The present invention relates to a picture display using CMOS (Complementary Metal Oxide Semiconductor) image sensor; and, more particularly, to a CMOS image sensor having a testing circuit embedded therein and a method for verifying operation of the CMOS image sensor using the testing circuit. The CMOS image sensor according to the present invention includes a control/interface unit for controlling its operation sensor using a state machine and for interfacing the CMOS image sensor with an external system; a pixel array including a plurality of pixels sensing images from an object and generating analogue signals according to an amount of incident light; a converter for converting the analogue signals into digital signals to be processed in a digital logic circuit; and a testing circuit for verifying operations of the converter and the control/interface unit, by controlling the converter.</PTEXT> |
