Abstract: A pixel array of an image sensor includes multiple red, green, blue and panchromatic pixels. The red, green and blue pixels are formed on a substrate during a first process. Planarization material is deposited to form the panchromatic pixels on the substrate and to form a planarization layer on the red, green and blue pixels during the same second process subsequent to the first process. The planarization material of the panchromatic pixels and the planarization layer is characterized in high transmittance and high aspect ratio.

Abstract: A method of increasing signal-to-noise ratio of a distance-measuring device includes a light-emitting component emitting a detecting light to a measured object during an emitting period for generating a reflected light, a delay period after the light-emitting component emitting the detecting light, a light-sensing component sensing the energy of the reflected light to generate a light-sensing signal, and obtaining a measured distance between the distance-measuring device and the measured object according to the energy of the detecting light and the light-sensing signal. Since the measured distance is longer than a predetermined shortest measured distance, the method can accordingly calculate a proper delay period for ensuring that the reflected light reaches the light-sensing component after the delay period. In this way, the light-sensing component does not sense the background light during the delay period, so that the signal-to-noise ratio of the light-sensing signal is improved.

Abstract: A light source transmits detecting light toward an object. The object reflects the detecting light and forms a reflected light. A sensor is used for sensing the reflected light. Then, an exposure control unit coupled to the sensor performs luminance convergence on the reflected light according to luminance of the reflected light sensed by the sensor. And a distance measurement device coupled to the sensor detects a distance between the object and the light source and/or the sensor according to an image position of the reflected light on the sensor.
