A handheld computing device comprises a display comprising an array of pixels illuminated by a plurality of visible light sources, and a plurality of infra-red light sources interleaved between the visible light sources, the IR light sources being actuable to emit diffuse IR light with a first intensity. A camera has an image sensor comprising an array of pixels responsive to infra-red light and a lens assembly with an optical axis extending from the image sensor through the surface of the display. A dedicated illumination source is located outside the display and is actuable to emit infra-red light with a second greater intensity. A processor is configured to switch between an iris region processing mode in which a subject is illuminated at least by the dedicated light source and a face region processing mode in which a subject is illuminated by the plurality of IR light sources.

The range-finding apparatus (1) includes a light source (200), an optical receiver (1103), a setting unit (100), a detector (1100), and a calculation unit (300). The light source (200) projects light with a first irradiation pattern in a first period and projects light with a second irradiation pattern in a second period. The optical receiver (1103) receives light to output a pixel signal. The setting unit (100) sets a reference signal on the basis of the pixel signal in the first period. The detector (1100) detects whether or not the pixel signal varies from the reference signal by a first value or more in the second period and outputs a first detection signal indicative of a result obtained by the detection. The calculation unit (300) calculates a distance to a to-be-measured object using the first detection signal.

An optical sensor includes first and second light detectors, an optical path, and an evaluation unit. The first light detector detects light in the infrared wavelength range. A light sensitivity of the CCD sensors of the first and second light detectors differ from one another with regard to a predefined wavelength range. The first and second light detectors include pixels in columns and situated next to one another so that a first longitudinal side of the first light detector adjoins a first longitudinal side of the second light detector, and the first and second light detectors receive light via the optical path. The first and second light detectors generate first and second measuring signals, respectively, from electrical charges. The evaluation unit receives the first measuring signals at a first sampling frequency and the second measuring signals at a second sampling frequency, and combines these to form an output signal.
