Portion region is anti-phase black.
A kind of imaging mode of the electronics black card device of camera-shooting and recording device, it comprises the following steps：
First, monochromatic anti-phase electrical screen is closed, and photo-sensitive cell is initially imaged；
2nd, monochromatic anti-phase processor obtains initial imaging data；If overexposure region be present and owe to expose region, control is monochromatic
Anti-phase electrical screen is opened, and the scope of the opened areas is consistent with the overexposure region of corresponding the data obtained；If without overexposure region,
Direct imaging exports picture；
3rd, monochromatic anti-phase electrical screen blocks light path synchronously anti-phase secondary imaging；Utilize the opening area of monochromatic anti-phase electrical screen
Domain is first blocked to overexposure region light path, and after allowing deficient exposure region first to expose certain time, monochromatic anti-phase electrical screen is just closed, now,
Owe to expose region and overexposure region exposes simultaneously, photo-sensitive cell obtains secondary imaging；
4th, imaging processor amendment secondary imaging data；
5th, imaging output picture.
The invention has the advantages that：
1st, monochromatic anti-phase electrical screen can accurately block light path into the overexposure region on photo-sensitive cell, whole so as to accurately control
The deficient exposure of individual picture of getting married and the exposure in overexposure region, allow camera-shooting and recording device really to be exposed consistent image (picture).
2nd, monochromatic anti-phase electrical screen can serve as mechanical shutter, make camera-shooting and recording device power consumption lower, be particularly suited for needing to prevent
Tremble image (picture) shutter for requiring high.
Brief description of the drawings
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is the schematic diagram of an embodiment.
Embodiment
Below in conjunction with the accompanying drawings and embodiment the invention will be further described.
Referring to Fig. 1-Fig. 2, a kind of this electronics black card device of electronics black card device camera-shooting and recording device, the camera-shooting and recording device bag
The photo-sensitive cell 1 and imaging processor 3 of interconnection are included, its electronics black card device includes monochromatic anti-phase electrical screen 2 and for controlling
The monochromatic anti-phase processor 4 that the monochromatic anti-phase electrical screen 2 of system switchs；Monochromatic anti-phase electrical screen 2 is layered in before photo-sensitive cell 1,
Monochromatic anti-phase processor 4 is connected with photo-sensitive cell 1, monochromatic anti-phase electrical screen 2.
Monochromatic anti-phase electrical screen 2 is region-wide to be transparent when closing, to be region-wide or local when monochromatic anti-phase electrical screen 2 is opened
Region is anti-phase black.
A kind of imaging mode of the electronics black card device of camera-shooting and recording device, it comprises the following steps：
First, monochromatic anti-phase electrical screen 2 is closed, and now monochromatic anti-phase electrical screen 2 is fully transparent, is not influenceed light path and is entered sense
Optical element 1, photo-sensitive cell 1 are initially imaged；
2nd, monochromatic anti-phase processor 4 obtains initial imaging data；If overexposure region be present and owe to expose region, control is single
The anti-phase electrical screen 2 of color is opened, and the scope of opened areas is consistent with the overexposure region of corresponding the data obtained, make monochromatic anti-phase region with
Overexposure region is overlapping, blocks the light path of the part, and fitting it can not temporarily be imaged on photo-sensitive cell 1；If without overexposure region, directly
It is connected into as output picture；
3rd, monochromatic anti-phase electrical screen 2 blocks light path synchronously anti-phase secondary imaging；Utilize the opening of monochromatic anti-phase electrical screen 2
Region is first blocked to overexposure region light path, and after allowing deficient exposure region first to expose certain time, monochromatic anti-phase electrical screen 2 is just closed, this
When, owe to expose region and overexposure region exposes simultaneously, photo-sensitive cell 1 obtains secondary imaging；
4th, imaging processor 3 corrects secondary imaging data, including amendment exposure, noise reduction, contrast, threshold value etc.；
5th, imaging output picture.
This electronics black card device operation principle：Monochromatic anti-phase electrical screen 2 is close to and is fixed on the photosurface of photo-sensitive cell 1,
It is a transparent electrical screen, light path can pass through and reach photo-sensitive cell when monochromatic anti-phase electrical screen 2 is not turned on work
On 1, after camera-shooting and recording device (camera, video recorder etc.) is to the initial imaging of light path, monochromatic anti-phase processor 4 will detect that the imaging picture
Overexposure region and owe to expose region, and drive the relative position in the monochromatic anti-phase corresponding overexposure region of electrical screen 2 to open, it opens area
Domain scope and imaging aspect ratio are in the same size, and real-time synchronization is anti-phase.During secondary imaging, owe exposure region and first obtain Correct exposure,
Then overexposure region presses dark process by relative, makes overexposure region also obtain due to being blocked and then just exposing at the beginning
Correct exposure, all balanced picture of whole picture exposure is then exported, be also beneficial to realize the noise reduction of picture.The black clamping of this electronics
Imaging can be combined with the photo-sensitive cell of camera-shooting and recording device by putting, and by the optimization of software, can further synthesize a variety of art pattern effects
Fruit, such as transparency, color range, emergence, contrast, threshold value, linear, soft light processing, when reducing many for user's post-processing
Between, increase the playability of camera-shooting and recording device.In addition, this electronics black card device also supports real-time anti-phase generation dynamic menu, can also expand
Shutter support, B doors etc. are opened up, the excessive remarkable fluency of image quality, noise reduction are good.
