Meanwhile, adopt 2*2 structure to facilitate realization reading photosensitive pixel output on hardwareGet and merge processing.
Refer to Figure 15 and Figure 13, in some embodiments, the white filter area 1313 of each merging pixel and colored filterLight district 1315 covers respectively two photosensitive pixels 111.
Like this, white filter area 1313 and colorized optical filtering district 1315 fully cover the photosensitive pixel 111 that merges pixel.
Refer to Figure 16, in some embodiments, imageing sensor also comprises control module 17, and control module 17 is for controlPhotosensitive pixel array 11 processed exposes line by line. Control module 17 is connected with row and selects logical block 171 and column selection logical block173, to control line by line, the output of photosensitive pixel 111 is processed.
The mode of exposing line by line and export more easily realizes on hardware.
See also Figure 16, in the present embodiment, imageing sensor 10 also comprises register 19, control module 17 useIn the colorful digital signal and the grey that gather successively photosensitive pixel 111 correspondences that k is capable and k+1 is capable that complete when prior exposureWord signal, and deposited in register 19, wherein k=2n-1, n is natural number, k+1 is less than or equal to photosensitive pixel array 11Total line number.
Concrete, referring to Figure 16, Figure 11 and Figure 12, imageing sensor comprises with row selects logical block 171 and column selectionThe control module 17 that logical block 173 connects. Row is selected logical block 171 and column selection logical block 173 and each senseThe switching tube 1115 of light pixel 111 correspondences connects, and control module 17 selects logical block 171 and column selection to patrol for controlling rowCollect the switching tube 1115 of unit 173 with the photosensitive pixel 111 of gating ad-hoc location.
First control module 17 controls photosensitive pixel 111 outputting analog signals of the first row and the second row, wherein colorized optical filtering districtThe analog signal of corresponding photosensitive pixel merges processing module through signal and merges into colored analog signal, and colored analog signal is through modulusConverter 211 is converted to colorful digital signal and deposits register 19 in. Wherein the structure of analog signal and principle refer to figureThe embodiment of 11～12 correspondences. The analog signal of the photosensitive pixel that white filter area is corresponding is directly converted to ash by analog-digital converterDegree data signal also deposits register 19 in.
Image processing module 50 extracts and processes colorful digital signal and gray scale data signal from register 19, to obtain corresponding closingAnd the pixel value of pixel.
By that analogy, until handle four photosensitive pixels of last group of the first row and the second row.
By above processing mode, the output of the photosensitive pixel to the third line and fourth line, fifth line and the 6th row etc. is processed,Until all the output of photosensitive pixel is all finished dealing with.
Refer to Figure 17, in some embodiments, imageing sensor 10 comprises the micro mirror array being arranged on optical filter 1323, each micro mirror 231 is corresponding with a photosensitive pixel 111.
Concrete, each micro mirror 231 is corresponding with a photosensitive pixel 111, comprises size, position correspondence. In some enforcement sideIn formula, each filter unit 1311 corresponding 2*2 photosensitive pixel 111 and 2*2 micro mirror 191. Along with technical development, forObtain the image that resolution ratio is higher, photosensitive pixel on sensitive film 111 is more and more, arrange more and more intensive, single light-sensitive imageElement is 111 also more and more less, and it is affected by light, and sensitization part 1111 areas of photosensitive pixel 111 are limited, micro-Mirror 191 can gather light sensitization part 1111, thus promotion feeling light pixel 111 be subject to luminous intensity to improve image quality.
In some embodiments, the pixel value of merging pixel comprises the color pixel values corresponding with colored analog signal and and gray scaleThe white pixel value that analog signal is corresponding, color pixel values forms the colored image that merges, and white pixel value forms gray scale and merges image.
So, image processing module closes according to the complete colour of color pixel values generation color information corresponding with colored analog signalAnd image, and it is higher to generate brightness according to white pixel value corresponding to gray scale analog signal, the less gray scale of noise merges image.
In some embodiments, image processing module also changes the colored subimage of yuv format into for colour merging image.Image processing module also for the brightness value of colored sub-image pixels is replaced with brightness value that gray scale merges image respective pixel fromAnd obtain merging image.
YUV is the picture format of describing color according to the principle of brightness and aberration, and yuv format comprises many concrete forms,As YUV422, YUV420 etc. In some embodiments, filter unit comprises green, redness, blue filter unit,Image processing module first obtains the coloured image of rgb format according to its corresponding photosensitive pixel output, obtain each image slicesRed brightness value, green brightness value, the blue brightness value of element, use respectively R, G, and B represents, its corresponding yuv formatThe brightness value Y=0.299*R+0.587*G+0.114*B of image pixel.
So, can obtain the colored subimage of yuv format.
Image processing module is used further to the brightness value of colored sub-image pixels to replace with the brightness that gray scale merges image respective pixelThereby value obtains merging image.
Owing to only having replaced the brightness value of colored sub-image pixels, therefore do not damage the integrality of its color information. Due to whiteFilter area has better translucent effect to make the brightness value of photosensitive pixel output higher, and therefore in low-light (level) situation, gray scale merges imageBrightness than colored merging image is higher, and noise is also less. Therefore after replacing brightness, make coloured image luminance raising, signal to noise ratio is carriedRise.
