An optical sensor including a pixel matrix and an opaque layer is provided. The pixel matrix includes a plurality of unblocked pixels, a first pixel and a second pixel, which is arranged at a side of the first pixel in a row direction of the pixel matrix. The opaque layer covers upon a first region, which is a part of the first pixel, and upon a second region, which is a part of the second pixel, but does not cover upon the unblocked pixels, wherein the first region and the second region are symmetrically arranged in the row direction, and uncovered regions of the first pixel and the second pixel are arranged to be larger at a pixel edge than at a pixel center in a column direction of the pixel matrix.

Optical sensor having opaque layer

An optical module including a light source and an optical sensor is provided. The optical sensor includes a pixel matrix and an opaque layer. The pixel matrix includes a plurality of unblocked pixels, a plurality of first pixels and a plurality of second pixels. The opaque layer covers upon a first region, which is a part of each first pixel, and upon a second region, which is a part of each second pixel, but does not cover upon the unblocked pixels, wherein the first region and the second region are symmetrically arranged in a first direction, and uncovered regions of the first pixels and the second pixels are arranged to be larger at a pixel edge than at a pixel center.

A headset controller takes a first touch sensor, a second touch sensor, a first pressure sensor, and a second pressure sensor as a control medium for users. The headset controller can generate four different output instructions by the users touching or pressing the operating interface. The headset controller integrates various sensing methods to generate the needed output instructions.

An imaging device including a condenser lens and an image sensor is provided. The image sensor is configured to sense light penetrating the condenser lens and includes a pixel matrix, an opaque layer, a plurality of microlenses and an infrared filter layer. The pixel matrix includes a plurality of infrared pixels, a plurality of first pixels and a plurality of second pixels. The opaque layer covers upon a first region of the first pixels and a second region of the second pixels, wherein the first region and the second region are mirror-symmetrically arranged in a first direction. The plurality of microlenses is arranged upon the pixel matrix. The infrared filter layer covers upon the infrared pixels.

Imaging device for distinguishing foreground

A physiological detection device including a light source, an image sensor and a processor is provided. The light source illuminates a skin surface using a burst mode. The image sensor receives ejected light from skin tissues under the skin surface at a sampling frequency to successively generate image frames. The processor controls the light source and the image sensor, and calculates a physiological characteristic according to the image frames captured when the light source is illuminating light. The physiological detection device reduces the total power consumption by adopting the burst mode.
