Abstract: An optical sensor (10) includes a first switch (SW1) and a second switch (SW2), these switches are switched between a first step and a second step and thus the coupling of light receiving portions (photodiodes) and three analog-to-digital converters (ADCs) is switched. In the first step of the switch, photocurrents generated in a blue light receiving portion (BLUE), a green light receiving portion (GREEN) and a red light receiving portion (RED) are processed in real time. In the second step, photocurrents generated in an infrared light receiving portion (Ir), an environmental light receiving portion (CLEAR) and the green light receiving portion (GREEN) are processed. The photocurrents of the infrared light receiving portion (Ir) and the environmental light receiving portion (CLEAR) generated in the first step are calculated from a ratio of the two photocurrents measured in the green light receiving portion (GREEN).

Abstract: The present disclosure relates to a proximity sensor. The proximity sensor includes: a light emitter (for example, a vertical cavity surface emitting LASER (VCSEL)) configured to irradiate light to a target to be inspected; a first light receiver having a first crosstalk characteristic, configured to detect an external reflected light from a target to be inspected within a first detection region (for example, 0˜5 cm approximately); and a second light receiver having a second crosstalk characteristic different from the first crosstalk characteristic, configured to detect an external reflected light from a target to be inspected within a second detection region (for example, 3˜60 cm approximately) relatively further than the first detection region.
