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: The present invention discloses a hybrid pointing device including an optical navigation module and a pointing module. The optical navigation module is configured to replace the conventional buttons of a convention pointing device, such as an optical mouse or a trackball mouse. The optical navigation module is configured to sense gestures of at least one object operated by a user to activate commands associated with particular programs running on the host. Since the optical navigation module is only configured to sense gestures of the object but not the movement of the hybrid pointing device relative to a surface, the resolution thereof is aimed to be sufficiently high enough for sensing gestures and no need to be relatively high.

Abstract: The present disclosure provides a time delay integration (TDI) sensor using a rolling shutter. The TDI sensor includes multiple pixel columns. Each pixel column includes multiple pixels arranged in an along-track direction, wherein two adjacent pixels or two adjacent pixel groups in every pixel column have a separation space therebetween. The separation space is equal to a pixel height multiplied by a time ratio of a line time difference of the rolling shutter and a frame period, or equal to a summation of at least one pixel height and a multiplication of the pixel height by the time ratio of the line time difference and the frame period. The TDI sensor further records defect pixels of a pixel array such that in integrating pixel data to integrators, the pixel data associated with the defect pixels is not integrated into corresponding integrators.
