Abstract: The present disclosure provides an image processing circuit including a neural network processor, a background processing circuit and a blending circuit. The neural network processor is configured to process input image data to determine whether the input image data has a predetermined object so as to generate to heat map. The background processing circuit blurs the input image data to generate blurred image data. The blending circuit blends the input image data and the blurred image data according to the heat map to generate output image data.

Abstract: A dual-processor system includes a power supply, a temporary memory, a non-volatile memory and two processors. The non-volatile memory stores an initialization program code, a first configuration file corresponding to a first operating system, and a second configuration file corresponding to a second operating system. Compared to the first operating system, the second operating system has a shorter interrupt latency and a shorter thread switching latency. After the power supply starts to supply power, the first processor executes the initialization program code to perform operations of initializing the temporary memory, loading the second configuration file into the temporary memory, notifying the second processor to fetch the second configuration file from the temporary buffer, loading the first configuration rile into the temporary memory and establishing the first operating system according to the first configuration file.

Abstract: A handheld electrical communication device includes an image sensing unit, an image signal processing unit, a storage unit, a display unit and a baseband processing unit. The image sensing unit generates an original image frame. The image signal processing unit adjusts the original image frame to be an adjusted image frame, scales the adjusted image frame to be a scaled image frame, and compresses the adjusted image frame into compressed image data. The storage unit stores the compressed image data. The baseband processing unit reads and outputs the compressed image data from the storage unit to the image signal processing unit. The image signal processing unit decompresses the compressed image data to be the adjusted image frame, scales the adjusted image frame to be the scaled image frame and outputs the scaled image frame to the baseband processing unit. The scaled image frame is displayed on the display unit.
