1. A power consumption control device applied to an electronic device, comprising:
an image signal processor (ISP), arranged to receive an image signal captured by a camera of the electronic device, and process the image signal to generate a processed image signal;
a storage device, arranged to store at least one predetermined image class;
a processing circuit, arranged to:
receive the processed image signal from the ISP;
receive the at least one predetermined image class from the storage device; and
analyze the processed image signal to detect whether the processed image signal belongs to the at least one predetermined image class to generate a control signal; and
a control circuit, arranged to switch a mode of the electronic device to a first mode or a second mode according to the control signal, and adjust a resolution or a frame rate of an image displayed on a display of the electronic device according to the mode of the electronic device, wherein power consumption and performance of the electronic device in the first mode are lower than the power consumption and the performance of the electronic device in the second mode, and the image displayed on the display of the electronic device is different from the image signal captured by the camera of the electronic device.
