1. A preview system of an image capture apparatus, comprising: a processing circuit, arranged for reading an input image, scaling at least a portion of the input image to generate a first preview image, and deriving a second preview image from a selected portion of the input image; and a display apparatus, arranged for displaying the first preview image and the second preview image, concurrently; wherein each of the first preview image and the second preview image is displayed while a trigger signal is generated by an input device of the image capture apparatus; when the trigger signal indicates a first status, a first mode is active; when the trigger signal indicates a second status following the first status, a second mode is active; and each of the first preview image and the second preview image is displayed during the first mode; and wherein when the trigger signal is not generated and none of the first mode and the second mode is active, the first preview image and the second preview image are both displayed on the display apparatus with a display size of the first preview image being larger than a display size of the second preview image; and while the trigger signal is generated to indicate the first status, the display size of the second preview image is increased under the first mode.
