    Abstract: A method and system provide light to project to an operation space so that a received image from the operation space will include, if an object is in the operation space, a bright region due to the reflection of light by the object, and identify a gesture according to the variation of a barycenter position, an average brightness, or an area of the bright region in successive images, for generating a corresponding command. Only simple operation and calculation is required to detect the motion of an object moving in the X, Y, or Z axis of an image, for identifying a gesture represented by the motion of the object.

    Abstract: An exposure adjusting apparatus, which comprises: an image sensor, for catching an image according to an exposure parameter; a computing apparatus, for computing an exposure amount of the image and for determining whether the exposure amount is in a predetermined exposure range or not; and an exposure updating apparatus. If the exposure amount is in the predetermined exposure range, the exposure updating apparatus does not adjust the exposure amount. If the exposure amount is not in the predetermined exposure range, the exposure updating apparatus generates at least one adjusting amount according to at least one of the predetermined exposure range, the exposure amount and the exposure parameter, and utilizes the adjusting amount to increase or decrease the exposure parameter to generate a new exposure parameter.
