As act on, just repeat no more herein.Second coil is AF coil (not shown)s, can play a part of focusing, can make bat
The picture taken the photograph is relatively sharp.
Alternatively, above-mentioned first photographing module 100 also includes the first imaging sensor, and above-mentioned first imaging sensor is
RGB image sensor.
RGB image sensor uses area image sensor, can be from CCD (charge-coupled device, electricity
Lotus coupled apparatus) and CMOS (complementary metal oxide semiconductor, CMOS is partly led
Body) one kind in both of which.
Either CCD or CMOS, the basic means that they are all captured using photo-sensitive cell as image, CCD/CMOS senses
The core of optical element is all a light sensitive diode (photodiode), and the diode can be produced after light irradiation is received
Output current, and intensity of the intensity of electric current then with illumination is corresponding.But on the composition of periphery, CCD photo-sensitive cell and CMOS's
Photo-sensitive cell is simultaneously differed, and the former photo-sensitive cell is in addition to light sensitive diode, including one is used to control adjacent charge
Memory cell, light sensitive diode occupies most areas --- and it is said differently and is exactly, the effective feeling in CCD photo-sensitive cells
Light area is larger, can under equal conditions receive stronger optical signal, and corresponding output electric signal is also more readily apparent.And CMOS feels
The composition of optical element is just more complicated, in addition to the light sensitive diode in core status, and it also includes amplifier and turned with modulus
Circuit is changed, the composition of each picture point is a light sensitive diode and three transistors, and the area that light sensitive diode is occupied is
The sub-fraction of whole element, causes the aperture opening ratio of cmos sensor to be far below CCD (aperture opening ratios：Effective sensitization area with it is whole
The area ratio of photo-sensitive cell)；So in the case of equal illumination and element size identical is received, CMOS photo-sensitive cells institute energy
The optical signal captured is just significantly less than CCD elements, and sensitivity is relatively low；It is embodied in output result, is exactly that cmos sensor is caught
The picture material grasped to enrich not as ccd sensor, and image detail loss situation is serious and noise is obvious, and this is also early stage
Cmos sensor is only used for a big reason of low side occasion.
RGB image sensor is the photo-sensitive cell of " color filter array " using one kind, is caught respectively in respective array
Catch a kind of in several pivot colors, most widely used CFA (color filter array, color filter array) is Bayer samples
Formula, it is respectively will be red green, and bluish-green wave filter difference is by rows.But bring the one of color filter array is not intended to
Side effect be that each pixel only captures the 1/3 of incident light because unmatched light can be filtered, such as：Feux rouges and indigo plant
Light is beaten can't be recorded on green pixel.
Alternatively, above-mentioned second photographing module 200 also includes the second imaging sensor, and above-mentioned second imaging sensor is
Mono imaging sensors.
Unlike RGB image sensor, each pixel of Mono imaging sensors captures all light come in, but regardless of
Colouring information, each pixel receives the light more than 3 times, because the light of red, green, blue color is all absorbed.
When being taken pictures under the illumination condition that artificial light or other colour temperatures and daylight are very different, Mono imaging sensors
Improve anti-noise performance.
Mono imaging sensors do not need demosaicing to receive the amount of light just with regard to that can obtain a sub-picture, each pixel
It is its pixel value, this enables Mono imaging sensors to realize higher resolution ratio.
Another benefit of Mono imaging sensors is that it can realize more predictable bloom reserved area, and RGB image
Red, green, blue can only occur for the bloom reserved area of sensor, in practice this means that black white image has more slightly higher available
Dynamic area, especially compared to coloured image, the monochromatic shade noise of image can be greatly reduced.
