    Abstract: An image sensing device that can adjust parameters of an image before sending it to a processor for reducing computing power and/or storage requirement is disclosed. The image sensing device includes an array of sensing pixels; an output amplifier; an analog-to-digital converter; a first set of registers and a second set of registers; an activation circuit; and a profiling logic. The profiling logic conducts statistical analysis on output data and adjusts parameters stored in the first set of registers until results of the statistical analysis reaches a target standard, wherein the adjusted parameters are used to generate an output image by each sensing pixel of the array of sensing pixels once the target standard is reached and a notification signal is sent to an external device for notifying the failure of parameter adjustment if the target standard fails to be reached within a predetermined times of adjustment.

    Abstract: A biometric security device for digital key storing is disclosed. The biometric security device includes a biometric information fetching module and a processing module. The processing module has a nonvolatile storage unit and a processing unit. The nonvolatile storage unit includes a secure storage unit and a general storage unit. The biometric security device with a secure electronic key designed for storing secret data utilizes both TrustZone™ technology (or similar technology) and biometric authentication. Thus, it can provide the flexibility for multiple users or applications to use the biometric security device or any equipment the biometric security device mounted in without compromising the safeguard of the data stored therein.
