Embodiment
Fig. 1 has shown a photographic means that comes the capturing high resolution digitized video with the low resolution photo-sensitive cell.Photographic means 1 has comprised lens assembly 11, MEMS (micro electro mechanical system) speculum (MEMS Mirror; Micro-Electro-Mechanical-Systems Mirror) 12, shutter device 13, lens devices 14, photo-sensitive cell 15, and casing 16.When the user presses external door button 131, extraneous light 5 enters photographic means 1 inside from lens assembly 11, via the reflection of MEMS (micro electro mechanical system) speculum 12, scioptics device 14 arrives photo-sensitive cell 15, is converted to electronic signal via photo-sensitive cell 15 and forms digitized video.Wherein, MEMS (micro electro mechanical system) speculum 12 can be done the swing of two dimension, and in its swing, photo-sensitive cell 15 can be done the action of pick-up image repeatedly, thereby photographic means 1 can produce the pixel value digitized video picture higher than photo-sensitive cell 15.
See also Fig. 4, photo-sensitive cell 15 generally can use CMOS or CCD chip, carries out image capture by the pixel inductor 151 that is a two-dimensional array 150 arrangements on it.See also Fig. 1 again, the single exposure action of photo-sensitive cell 15 can be after the user presses shutter release button 131, finishes between the opening and closing movement of the opening 132 on the shutter device 13.And when the photo-sensitive cell 15 of use such as CMOS or CCD chip, shutter device 13 also can omit, and uses electronic shutter to finish exposure actions.In exposure actions once, on each pixel inductor 151 because of electric charge that photoelectric action produced, being sent to a charge storage (not shown) under the voltage control of an applied voltage stores, and stored charge signal has different powers because of corresponding pixel inductor 151 is subjected to light situation difference in each charge storage, and these charge signals promptly can form a digitized video picture through suitable conversion again.Traditionally, promptly form a digitized video picture behind CCD or the CMOS chip single exposure, so the resolution of this digitized video picture is subject to the number of pixel inductor on the chip fully.In the present invention,, cooperate the multiexposure, multiple exposure of photo-sensitive cell 15, form the pixel value digitized video picture higher than the pixel value of photo-sensitive cell 15 by the swing of MEMS (micro electro mechanical system) speculum 12.For instance, if will obtain the digitized video picture of one 270 ten thousand pixels, as long as the CMOS chip that uses one 30 ten thousand pixels is as photo-sensitive cell 15, and when the user presses shutter release button 131, allow photo-sensitive cell 15 when 9 different time points, MEMS (micro electro mechanical system) speculum 12 present 9 kinds of different reflection angles, respectively carry out single exposure, each exposure all can get the digitized video subframe of one 300,000 pixel, again these 9 digitized video subframes are merged, get final product the digitized video picture of one 270 ten thousand picture elements.Certainly, the time point that the selected and MEMS (micro electro mechanical system) speculum 12 of these nine time points swings to some special angle must cooperate, so that each digitized video subframe is able to amalgamation smoothly.Use the photo-sensitive cell of 300,000 pixels can produce the digital camera that to clap 2,700,000 pixel picture specifications.And under same size, the CMOS chip unit picture element average area of 300,000 pixels is higher 9 times than the CMOS chip of 2,700,000 picture elements, can solve the problem of pixel element light-inletting quantity deficiency when small size designs in view of the above.
Fig. 2 is the concrete structure schematic diagram of MEMS (micro electro mechanical system) speculum 12.MEMS (micro electro mechanical system) speculum 12 is made with semiconductor fabrication, and its middle body is a minute surface 123, and its surperficial sputter for example has metal such as aluminium to increase its reflectance.Minute surface 123 is connected to a center 124 with rotating shaft 122, makes minute surface 123 be able to rotate around the y axle.Along the x direction of principal axis rotating shaft 121 is arranged then, connect center 124 and housing 125, make center 124 be able to rotate around the x axle together with minute surface 123.Against the changes of magnetic field that MEMS (micro electro mechanical system) speculum 12 internal wiring (not shown) are produced, may command minute surface 123 is in x axle and axial hunting frequency of y and angle.Speculum also can use one dimension speculum 32 as shown in Figure 3, and its minute surface 323 is connected to housing 324 with rotating shaft 321, can rotate around the z axle.Certainly, when the speculum that uses the one dimension direction to rotate, selecting for use of photo-sensitive cell also needs to adjust thereupon, just can reach the effect that obtains high pixel value digitized video picture with low-pixel value photosensitive element.
Can be observed by optical path shown in Figure 4, treat certainly, reflect to 12 reflections of MEMS (micro electro mechanical system) speculum, again by being sent to photo-sensitive cell 15 behind lens devices 14 light harvestings through lens assembly 11 according to the light that body surface reflected in the scene scope 6.Treat that being the user according to scene scope 6 (can be mechanical type or electronic type in the picture window of photographic means 1, not shown in the figures) scope of viewed scene, it is divided into scene scope 61 a plurality of times, and each time scene scope 61 is the image capturing range of photo-sensitive cell 15 single exposures institute fechtable just.Because time scene scope 61 can utilize the two dimension of MEMS (micro electro mechanical system) speculum 12 to swing the multiexposure, multiple exposure that adds photo-sensitive cell 15 less than treating according to scene scope 6, obtains one than the high digitized video picture of photo-sensitive cell 15 pixel values own.After the user presses shutter release button 131, MEMS (micro electro mechanical system) speculum 12 is promptly swung between each angle that can be reflected to each time scene scope 61, when it is rocked to the corresponding angle that can reflect certain time scene scope 61, photo-sensitive cell 15 promptly carries out single exposure, and obtain a digitized video subframe, be rocked to next suitably angle afterwards again, and next scene scope 61 exposed, so progressively finish after the exposure of all times scene scope 61, the digitized video subframe that again all is obtained merges, and can obtain a high-resolution digitized video picture.
Merge the work of digitized video picture, can finish by a processor.This processor can be the built-in processor of photographic means itself, also can be the processor in other computer system such as the personal computer.Fig. 8 has shown the part calcspar of the photographic system of the acquisition that can finish the digitized video subframe and merging, and the part of wherein relevant camera lens, fast gate control and speculum etc. is omitted at this.Photographic means 200 contains photo-sensitive cell 202, processor 203, internal memory 204, and storage device 205.Photographic means 200 can be connected by input/output interface (I/O interface) 206,305 with the personal computer 300 with processor 303 and internal memory 304.Ways of connecting can be utilized USB (USB, Universal Serial Bus) or other input/output interface.When using photographic means 200 processor inside 203 to carry out the merging of digitized video subframe, photographic means 200 itself promptly can be considered a photographic system.But sometimes under cost consideration, can give personal computer 300 with the work that merges the digitized video subframe finishes, can be considered as a complete photographic system in the lump this moment with photographic means 200 and personal computer 300, and be responsible for carrying out the processor 303 (generally be the central processing unit of this personal computer) of processor in this is personal computer 300 that the digitized video subframe merges, and photographic means 200 processor inside 203 can be selected the more cheap product of price for use.The digitized video subframe can be temporarily stored in internal memory 204, the storage device 205 of photographic means 200 earlier, or in the internal memory 304 of personal computer 303, is read by processor 203 or 303 and merges.When storage device 205 during for the detachable device that can separate with casing 16 as Fig. 1 as storage card etc., photographic means 200 also can not need directly to connect personal computer 300, but earlier each digitized video subframe is stored in the storage device 205, again storage device 205 is taken personal computer 300 places, read processing with input/output interface 305 or other input/output interface (not shown).Merge the digitized video picture of finishing, then can be stored in other storage device (not shown) of storage device 205, internal memory 304 or personal computer 300.
Fig. 9 has shown a typical digitized video picture 60, and it is combined by 9 digitized video subframes 601.After the user pressed shutter release button, digitized video subframe 601 promptly formed in the several exposure of photo-sensitive cell 202, and is deposited in the storage device 205 in regular turn.Because present digital camera all can use mode such as firmware to come the form of control figure image files name, therefore, if desire forms the archives IMG_01.jpg of a digitized video picture 60, can allow digitized video subframe 601 exposure in regular turn form the back with shelves name IMG_01-1.jpg, IMG_01-2.jpg ... the ..IMG_01-9.jpg deposit, come amalgamation to become digitized video picture 60 according to the mutual to each other geometry site of each digitized video subframe 601 in the coded sequence again, and deposit is IMG_01.jpg.
Photo-sensitive cell used in the present invention is not limited to use two-dimensional array to arrange the sensitive chip of pixel inductor, also can use the photo-sensitive cell of different types under difference is considered.Photographic means 2 is as shown in Figure 5 reflected to speculum 22 that can the two dimension swing through lens assembly 21 by the light for the treatment of to be reflected according to objects in the scene scope 7, is concentrated to photo-sensitive cell 25 again after reflexing to lens devices 24.Unlike last embodiment is to carry out the sensitization action by a plurality of optical diodes (photodiode) that are formed on the chip, photo-sensitive cell 25 is made of single optical diode, the reflection of the speculum 22 by can two dimension swing and the light harvesting of lens devices 24, can with by the light for the treatment of to be reflected according to objects in the scene scope 7 complete be collected into photo-sensitive cell 25, this action is simulated operation, change into digital signal by analog/digital converter again, form the digitized video picture at last.Because the price of single optical diode inductor is cheap more many than chip, present embodiment is having extraordinary effect aspect the cost that reduces product.
Fig. 6 shows another one embodiment of the present invention.Photographic means 3 light that object is reflected in treating according to scene scope 7 reflects to MEMS (micro electro mechanical system) speculum 32 by behind the light harvesting of lens assembly 31, reflexes to lens devices 34 again, is concentrated at last to be projected to photo-sensitive cell 35.Different with aforementioned each embodiment is that photo-sensitive cell 35 is linear photo-sensitive cells, can be made up of the optical diode that is the one-dimension array arrangement.Owing to use linear photo-sensitive cell, so 32 of MEMS (micro electro mechanical system) speculums need use to get final product with the produced one dimension MEMS (micro electro mechanical system) of semiconductor technology speculum.And linear photo-sensitive cell 35 exposes at every turn, only forms a strip digitized video subframe of scenery in time scene scope 71, is combined into by each subframe to present the digitized video picture for the treatment of according to complete scene in the scene scope 7 again.
