    摘要: The disclosed subject matter is directed to solid state cameras and sensor systems that include a pickup surface thereof with both a distance detecting area for measuring a distance from a moving object and a movement detecting area for detecting the object's movement. The device can also include an optical communication area for communicating with an outside communication device. Therefore, the device enables a single pickup surface to include at least the following three functions: distance measurement; movement detection; and optical communication. The above-described sensor systems can output a control signal for collision avoidance with stationary or moving obstacle(s) by using the solid state camera. Because the sensor system can be integrated as a single chip IC with a small size, the system is useful as a sensor device in a vehicle, a robot, and the like.

The plurality of light sources can be configured to emit a plurality of pulsed lights towards an object from different directions, and a photo-detector can be configured to serially detect the light reflected from the object. A determination of whether the object is moving further away or coming closer to the apparatus can be judged by calculating at least one of a position, an area and a brightness of the object from the reflected light and comparing the data with the previous data for the same value(s). Thus, because the method of the disclosed subject matter does not require a measurement of time as in the conventional methods, the method can result in providing a similar apparatus with a simple configuration and at a low cost, and can be used as a sensor for detecting an obstacle and the like in a vehicle, alarm system, etc.
