A CMOS image sensor with global shutter mechanism, HDR capability and high shutter efficiency has been designed and tested. The image sensor consists of a 128x128 pixel array, readout circuitry and special components for global shutter and skimming operations. The Image sensor has been designed using $AMS opto 0.35\mu m$ process. Hardware and software has been successfully added for testing and verification purposes. The global shutter functionality has been verified through comparison with a rolling shutter camera under the same conditions. Furthermore the HDR skimming technique has been implemented and verified through comparison with a normal capture operation.
