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.
