    Abstract: An electronic device includes an OLED display having a plurality of pixels and an ambient light sensor disposed under a first pixel of the plurality of pixels. In a first sensing interval, the ambient light sensor generates a first sensing value. The first sensing interval includes a first period and a second period. The first pixel has a first brightness in the first period and has a second brightness the second period. In a second sensing interval, which has the same time length as the first sensing interval, the ambient light sensor generates a second sensing value. The first pixel has the second brightness in the second sensing interval. The first pixel has an identical hue in the first sensing interval and the second sensing interval. The ambient light sensor acquires an ambient light intensity according to the first sensing value and the second sensing value.

    Abstract: A method for determining non-contact gesture is applied to a device for the same. The device has an image sensor to detect an image sensing data, an inertial measurement sensor to detect an inertial sensing data, and a processor to determine if an object data is detected and to determine if an inertial event is occurred. The image sensing data in the same and/or adjacent image frame with the inertial events are excluded so that the image sensing data used to determine the gesture are those not influenced by the inertial events. Therefore, the accuracy of determining the gesture is enhanced.

    Abstract: A complementary metal-oxide-semiconductor depth sensor element comprises a photogate formed in a photosensitive area on a substrate. A first transfer gate and a second transfer gate are formed respectively on two sides of the photogate in intervals. A first floating doped area and a second floating doped area are formed respectively on the outer sides of the first transfer gate and the second transfer gate. The first and second floating doped regions have dopants of a first polarity and the semiconductor area has dopants of a second polarity opposite to the first polarity. Since the photogate and at least parts of the first and second transfer gates connect to the same semiconductor area and no other dopants of polarity opposite to the second polarity. Therefore, the majority carriers from the photogate excited by lights drift, but not diffuse, to transfer to the first and second transfer gates.

    Abstract: An optical sensor apparatus includes an infrared light generating device, N first detection devices, a second detection device and a processing circuit. In addition to detecting infrared light, the N first detection devices further detect N different visible wavelength ranges, respectively. The second detection device is optically shielded from visible light and arranged for detecting infrared light. In a first sensing mode, the processing circuit obtains color information according to N first detection signals generated by the N first detection devices and a reference signal generated by the second detection device. In a second sensing mode, the N first detection devices and the second detection device generate (N+1) second detection signals when the infrared light generating device is activated, and generate (N+1) third detection signals when the infrared light generating device is deactivated. The processing circuit recognizes gesture information according to the (N+1) second and the (N+1) third detection signals.
