When projecting a video in conformity to the shape of a three-dimensional object using a projector, a pattern such as a grid is projected and the projected pattern is photographed, and then the position or shape of a projection object is calculated, whereby making it possible to apply appropriate geometric transformation to a projected video. However, when a grid is projected in superposition while video content is being displayed, the grid is visible to a viewer, and that the position or shape of a projection video cannot be calculated while a video content is being displayed. The present invention uses the freedom of color representation and the color redundancy of a color wheel, buries an invisible pattern not visible to human eyes in a video, and photographs the video in synchronism with the rotation of the color wheel, thereby making it possible to discriminate the buried invisible pattern.

An image detection unit extracts image feature values from images of each camera. An image conversion unit computes a blend rate according to the image feature values and composites an image of a superposition area wherein a plurality of camera images overlap. An assessment is made of a correspondence of the image feature values of each image in the superposition area, and a determination is made that a solid object is present if the correlation is weak. Furthermore, a determination is made that the solid object is present in the superposition area if the image feature values in each image have locationally overlapping portions. In such a circumstance, the image is composited with the blend rate of the image with a greater image feature value set large.

Impact detecting resistors (), () of an impact detecting circuit () detect a counter electromotive force of a step motor () generated due to an impact. This counter electromotive force is amplified applying a predetermined period and a predetermined chopper-width by a chopper-amplifying waveform shaping circuit (). Therefore, even a light impact can be detected. Inverters (), () compare these impact detecting signals (S), (S) with a threshold value and detect an impact when the signals exceeds the threshold value. A controlling circuit () provides a lock pulse to the step motor () through signal lines (AA), (BB) when an impact is detected, brakes rotation of a rotor () thereby preventing a deviation of the time displayed with a second hand ().

When a stem switch () is pulled out, a switch signal forming unitoutputs a signal (RS) indicating that effect, a control unit () receives the signal (RS) and starts clocking by a timer (). The control unit () receives a signal (HS) output from an electricity-generation detecting unit () within the clocking period, detects the electricity generating operation of an electricity generating unit (), and outputs a signal (CS) indicating that effect. A narrow pulse forming unit () forms a narrow pulse having a width of such a degree that the motor () is not driven based on the signal (CS), and outputs the narrow pulse to a motor driving circuit (). The motor driving circuit () flows a fine current through a coil () which drives the motor () based on the narrow pulse. An external device detects a variation of the narrow pulse, thereby confirming whether electricity is generated.

Electronic timepiece

In detecting power generation of an electronic timepiece having a conventional power generating unit, voltage output by the power generating unit is limited by output from a storage unit since the power generating unit and the storage means are connected when the power generation state is detected, and voltage equal to or larger than voltage output from the storage unit cannot be detected. An electronic timepiece is provided which can overcome the problem and can check an operation of the power generating unit securely irrespective of the state of the storage means. In an electronic timepiece driven by power stored from a power generating unit () into a storage unit (), the electronic timepiece includes a power generation detecting unit () that detects a power generation state of the power generating unit () and a switch unit () that separates the power generating unit () and the storage unit () when the power generation state of the power generating unit () is detected. In this case, the switch () between the power generating unit () and the storage unit () is controlled to OFF so that the output from the power generating unit () cannot be limited by the output from the storage unit ().
