摘要： Disclosed are a pixel unit, and an imaging method and apparatus thereof. The pixel has a first and a second pixel sub-portion each comprising one or more photodiodes; one or more transfer transistors each coupled to a floating diffusion, for transferring the charges generated by the one or more photodiodes in response to incident light during an exposure period and accumulated in the photodiode during said exposure period respectively to the floating diffusion; a reset transistor; and a source follower transistor coupled to the floating diffusion for amplifying and outputting the pixel signal of the floating diffusion. In some embodiments, the pixel further includes a capacitor and a gain control transistor.

摘要： A CMOS image sensor with an imaging array of pixels containing selected pixels wherein illumination from a normal image is received by one set of pixels and illumination from an LED light source is received by another. The readout method serially separates the normal image signal from the LED light sourced signal. The signal from the selected pixels is resilient against saturation and thereby contributes to increased HDR. The image sensor array and readout method may be incorporated within a digital camera.

摘要： A CMOS image sensor with an imaging array of pixels containing selected pixels wherein illumination is blocked and light scattered from an adjacent pixel is collected. The signal from the selected pixels is resilient against saturation and thereby contributes to increased dynamic range of the imaging signal. The image sensor may be incorporated within a digital camera.

摘要： An imaging system with an array of pixel cell units having four photodiodes sharing the same readout amplifier, row select transistor, microlens and filter color. Some pixel cell units provide a phase detection autofocus function. The imaging system provides the option of imaging with phase detection autofocus and with or without horizontal or vertical binning readout modes, or both simultaneously, to form an a full resolution image of the target scene with improved effective frame rate and improved slow motion imaging.
