Patent Description:
Currently, a photoelectric sensor in a camera senses light similarly to human eyes. A red-green-blue (Red-Green-Blue, RGB) color filter array (color filter array, CFA) covering pixels of the photoelectric sensor simulates three types of cone cells of the human eyes, and samples a spectral reflection curve to form a digital signal, which is processed by image signal processing (Image Signal Processing, ISP) and finally becomes an image.

The photoelectric sensor senses light differently from the human eyes in that each pixel in the photoelectric sensor can acquire only one of R, G and B signals, while the cone cells of the human eyes are densely distributed, which may be equivalently understood as that each pixel simultaneously acquires R, G and B signals. The use of the above photoelectric sensor may lead to false colors in the generated image relative to details of the image perceived by the human eyes. That is, serious artificial traces such as color fringing and other false color effects may be produced in the image.

Therefore, how to eliminate the false color effects of the photoelectric sensor has become an urgent technical problem.

<CIT> discloses image-sensing display panels with LCD display panel and photosensitive element array.

<CIT> discloses arrayed imaging systems which include an array of detectors formed with a common based and a first array of layered optical elements, each one of the layered optical elements being optically connected with a detector in the array of detectors.

An objective of embodiments of the present disclosure is to provide a pixel unit, a photoelectric sensor, a camera module, and an electronic device, to resolve the technical problem of the false color effects of the photoelectric sensor in the camera module.

In the pixel unit according to the embodiment of the present disclosure, light passing through the optical splitter is divided into three beams of light in different directions, which respectively enter the red photodiode, the green photodiode and the blue photodiode, so that the pixel unit can simultaneously acquire R, G and B signals, effectively eliminating the false color effects of the photoelectric sensor.

Examples of a storage medium of a computer includes, but is not limited to, a phase change memory (PRAM), a static random access memory (SRAM), a dynamic random access memory (DRAM), or other types of random access memory (RAM), a read-only memory (ROM), an erasable programmable read only memory (EEPROM), a flash memory or another storage technology, a compact disc read-only memory (CD-ROM), a digital versatile disc (DVD) or another optical storage, or a cartridge tape. A magnetic storage of a magnetic tape or a disc, another magnetic storage device, or any other non-transmission medium may be configured to store information that can be accessed by a computing device. Based on the definition in this application, the computer-readable medium does not include transitory computer-readable media (transitory media), such as a modulated data signal and a carrier.

It may be understood that, the embodiments described in the embodiments of the present disclosure may be implemented by using software, hardware, firmware, middleware, microcode, or a combination thereof. For hardware implementation, a processing unit may be implemented in one or more application specific integrated circuits (Application Specific Integrated Circuits, ASICs), a digital signal processor (Digital Signal Processor, DSP), a DSP device (DSP Device, DSPD), a programmable logic device (Programmable Logic Device, PLD), a field-programmable gate array (Field-Programmable Gate Array, FPGA), a general-purpose processor, a controller, a micro-controller, a microprocessor, and other electronic units configured to execute the functions in the present disclosure, or a combination of the above.

For implementation by software, the technologies in the embodiments may be implemented by performing the functional modules (for example, a process and a function) in the embodiments of the present disclosure. Software code may be stored in a memory and executed by a processor. The memory may be implemented inside or outside the processor.

It should also be noted that, in this specification, the terms "include", "comprise" and any other variants mean to cover the non-exclusive inclusion. Thereby, the process, method, article, or device which includes a series of elements not only includes those elements, but also includes other elements which are not clearly listed, or further includes the inherent elements of the process, method, article or device. Unless otherwise specified, an element limited by "include a/an. " does not exclude other same elements existing in the process, the method, the article, or the device that includes the element.

Through the descriptions of the foregoing implementations, a person skilled in the art may clearly understand that the methods in the foregoing embodiments may be implemented by software and a necessary general hardware platform, and certainly, may also be implemented by hardware, but in many cases, the former manner is a better implementation. Based on such an understanding, the technical solutions of the present disclosure essentially or the part contributing to the prior art may be implemented in a form of a software product. The computer software product is stored in a storage medium (such as a ROM/RAM, a magnetic disk, or an optical disc) and includes several instructions for instructing a terminal (which may be a mobile phone, a computer, a server, an air conditioner, a network device, or the like) to perform the methods described in the embodiments of the present disclosure.
