Claim:
1. A camera, comprising: a lens; at least one operation unit actuating according to at least one operation power correspondingly; an image sensor for receiving images from the lens; a thermal sensor for performing temperature sensing and outputting a sensing temperature; and wherein an amount of the at least one operation power is controlled to make a first monitoring power owned by the camera close to but not greater than a default power threshold, and to make the sensing temperature not greater than a first default temperature threshold, wherein the first monitoring power is the sum of the at least one operation power and the sensing temperature corresponds to the at least one operation power; wherein the at least one operation unit includes a light-emitting component and a fan, and the light-emitting component and the fan actuate according to the respective operation power correspondingly, and the default power threshold corresponds to a power upper bound of the light-emitting component and the fan, and the first monitoring power is the sum of the operation power of the fan and the operation power of the light-emitting component, and when the sensing temperature is less than the first default temperature threshold, the operation power of the light-emitting component is controlled to make the first monitoring power close to but not greater than the power upper bound; when the sensing temperature is greater than or equal to the first default temperature threshold and a difference between the first monitoring power and the default power threshold is enough to drive the fan, the fan is driven; when the sensing temperature is greater than or equal to the first default temperature threshold and the difference between the first monitoring power and the default power threshold is not enough to drive the fan, the fan is driven at which the operation power of the light-emitting component is reduced to the difference for driving the fan.
