Mobile terminal carries dual camera, carries DSP special image processing chips.The pan-shot under easily shake scene
When, a camera is with normal exposure parameter output image, when a camera exposes with the 1/4 of first camera in addition
Between, the exposure parameter output image of 2 times of gain (gain generally refers to luminance gain), DSP can be in the time of a frame simultaneously
Get the image of a normal exposure, 4 images for owing to expose, because black white image has more details, noise is few, and colour is taken the photograph
As a coloured multimedia message, the image after synthesis has the effect of noise reduction.Several images that pan-shot needs, are all first
Carry out colour by DSP and blacken the synthesis of white noise reduction algorithm, then by ISP image procossings into YUV image, then carry out panorama conjunction
Cheng Shi, obtained panoramic picture is exactly a smaller panoramic picture of noise.
Specific implementation step is as follows：
Step C1：Dual camera is opened simultaneously；
Two cameras are all connected on DSP, and DSP obtains what two cameras were exported simultaneously in the time of each frame
Image.
Step C2：Start photographing panorama picture；
Generally requiring several images of shooting is used to synthesize panoramic picture.Mobile terminal can detect the angle of user's rotation, when
When needing to shoot an image, send one and grab frame instruction one two field picture of crawl, finished until several two field pictures of needs are all captured,
Panoramic picture synthesis is carried out again.
Step C3：DSP, which detects whether to receive, grabs frame request；Frame request is grabbed if received, into step C4, otherwise, is entered
Step C5；
Step C4：Stabilization image after synthesis is exported to AP；
Step C5：Normal exposure image is exported to AP；
Step C6：Panorama Mosaic synthesis is carried out in DSP.
Using this example, there is shake when shooting, but the panoramic picture shot is to be entirely clear, rather than mould
Paste, improve Consumer's Experience.
