A method of producing an image is disclosed. A reference track is received. The reference track is, optionally, displayed on a preview image with at least one light spot. Subsequently, a position of an incident light projected on an image sensor of an image capturing device is varied during an exposure period to trace the reference track. Accordingly, the image with a light track that traces the reference track is captured.

Method of producing a still image

A method of producing an image is disclosed. At least one symbol is received. A first image with at least one light spot is, optionally, captured by an image capturing apparatus. The performing order of receiving the symbol and capturing the first image may be reversed. The first image is duplicated to provide a plurality of duplicated first images, and the duplicated first images are shifted according to the symbol to obtain a plurality of shifted first images. The brightness values of corresponding pixels of the shifted first images are computed to produce a second image with a light track that traces the symbol.

A method of determining shift between two images is disclosed. A first array of pixel data of a first image is mapped to a first feature array(s) having a dimension lesser than the first array, and a second array of pixel data of a second image is mapped to a second feature array(s) having a dimension lesser than the second array. The second feature array is aligned with the first feature array by determining similarity between the first feature array and a number of the shifted second feature arrays. The position shift of the shifted second feature array with most similarity is thus determined as the shift between the two images.

A method of dynamically changing a parameter of a frame is disclosed. An input frame is determined as a special scene or a general scene. A subsequent frame is predicted by changing the parameter of the subsequent frame according to a special-scene operation when the input frame is the special scene, and by changing the parameter of the subsequent frame according to a general-scene operation when the input frame is not the special scene. The predicted frame is determined whether to be a special scene. Accordingly, the parameter of the input frame is changed according to the special-scene operation when both the input frame and the predicted frame are the special scenes; the parameter of the input frame is changed according to the general-scene operation when both the input frame and the predicted frame are not the special scenes; and the parameter of the input frame is maintained without change when only one of the input frame and the predicted frame is the special scene.

In an anti-shake circuit for an imaging device, a differential circuit receives an analog sensing signal and a target signal and then generates a difference signal. An analog mathematical circuit performs at least one mathematical operation on the difference signal, resulting in generation of at least one mathematical output signal. A driver receives the at least one mathematical output signal, and, accordingly, generates a driving signal and controls an actuator in order to correct the shaking movement.
