Abstract: A method of an optical sensor device used for detecting a color of a specific surface of an object includes: providing a sensor array having a plurality of pixel units each for receiving light reflected from the specific surface to generate a sensed pixel value; using the sensor array to generate a specific image formed by a plurality of sensed pixel values; determining whether the specific image is similar to a first solid color image corresponding to a first color according to the plurality of sensed pixel values of the specific image; and determining to execute a distance detection operation to calculate a specific distance from the optical sensor device to the specific surface according to a color saturation value of the first color in the specific image when it is determined that the specific image is similar to the first solid color image corresponding to the first color.

Abstract: An optical decoding device, comprising: an image sensor, configured to sense first sensing images and second sensing images; a processing circuit, configured to determine a relative movement between the optical decoding device and an object according to the first sensing images; and a decoding device, configured to decode the second sensing images in a first mode to generate a decoding result and does not decode the second sensing images in a second mode. The decoding device switches between the first mode and the second mode according to the relative movement, thus can save power. A barcode, a color code which can be provided on a curved surface and an invisible code are also disclosed. An electrical cigarette lighter using the optical decoding device to provide heat is also disclosed.

Abstract: The disclosure is related to a sensor module, a sensor unit and a system for recognizing surrounding objects and defining an environment. The sensor module is installed in a sensor unit. The sensor module includes an optical element guiding the lights from the objects surrounding the sensor unit and to an image sensor, and the image sensor is used to sense the lights from the objects. The light can be directly from a light source inside the surrounding object or reflected by the object surface. The objects can be identified according to optical features obtained by the image sensor from surfaces of the objects. When the image sensor receives the two lights, guided by the optical element, and reads optical features being regarded as the unique IDs to identify the objects respectively. Therefore, an environment around the sensor unit can be defined.
