Abstract
By using a specially-designed curved-surface reflector, the direction of light from a radiated object via a pin hole is regularly changed such that the light converges on the image sensor of a digital camera (or internally-arranged imaging system) in order to take digital pin-hole photos.
Description
Technical field
The present invention relates to a kind of novel pinhole photographic lens, coordinate digital camera to use or built-in digital image-forming module, can directly take digital pin hole photo with great visual angle.
Background technology
Pin-hole imaging is a kind of ancient Imaging, pinhole camera have unique large depth of field, with great visual angle, dim imaging, strongly but not distortion of perspective, the characteristic such as angle secretly naturally, deeply pursued professional photographer and the shutterbugs' of unique imaging effect and artistic environment favor.
Carry out at present pinhole photography creation, mainly still use film directly to expose to pin hole image, existence find a view predicament, long processing period, exposure control difficulty, expense high, can not see the shortcomings such as effect while taking at once, and at present, no matter be works modification, storage or printing and publishing, all need digitized video, it is digital photograph that the pin hole photo of film photographic finally still needs by scanning, the electricity technical change that grades.
Although also can lead to logarithmic code camera, reequip, with digital camera, directly carry out pinhole photography, the image area sensor of existing digital camera is too little, and visual angle is restricted, and is difficult to present the perfect effect of pinhole photography.If adopt picture of large image scale sensor production pinhole camera, not only cost is very expensive, and due to the restriction of imageing sensor sensitization mode, not good for the light photosensitive property of large incident angle, cause the image quality of image field periphery not good.
Summary of the invention
In order to solve the deficiency of existing pinhole camera, with lower cost, take digital pin hole photo, the invention provides a kind of novel pinhole photographic lens, coordinate existing digital camera to use, or built-in digital image-forming module, can take the shooting effect of similar large format film pinhole camera.
The technical solution adopted for the present invention to solve the technical problems is: use a curved reflector to converge the light of injecting from pin hole, it is projected on imageing sensor with set angle, thereby take digital pin hole image.
The invention has the beneficial effects as follows: use this device, can live view under intense light irradiation condition, can accurately control exposure, after shooting, obtain immediately digital photograph, understand shooting effect, in use procedure without material consumption, the cheap and environmental protection of expense.Owing to making light arrive at imageing sensor with less incident angle, image quality increases.
Accompanying drawing explanation: Fig. 1 is the light path principle schematic diagram that the present invention coordinates with existing digital camera fuselage.
Fig. 2 is the light path principle schematic diagram of the built-in imaging system of the present invention.In figure: 1-incident light; 2-pin hole; 3-front apron; 4-unthreaded hole; 5-imageing sensor (CCD/CMOS); 6-curved reflector (micro reflector array); The signal of 7-micro-reflector minute surface.
embodiment:
In Fig. 1, front apron 3, curved reflector 6 form a lucifuge magazine, pin hole 2 is positioned on front apron, from the light 1 of object, through needle passing hole 2, project on curved reflector 6, catoptron is by the changed course of light rule, and light, by unthreaded hole 4, projects with less incident angle on the imageing sensor 5 of camera, with the shutter control exposure of camera, take into digital pin hole photo.
In Fig. 2 example illustrated, front apron 3, curved reflector 6 forms a lucifuge magazine, and pin hole 2 is positioned on front apron, from the light 1 of subject, through needle passing hole 2, projects on curved reflector 6, catoptron, by the changed course of light rule, projects photosensitive imaging on imageing sensor 5.
Because conventional curved reflector is difficult to meet the demand for control of this device to radiation direction, catoptron 6 can adopt micro reflector array to form curved reflector, and the minute surface direction of micro-reflector is as shown in 7.
Claims (4)
1. a reflection-type pinhole photographic lens, is comprised of pin hole and curved reflector, it is characterized in that, pin hole is positioned on the baffle plate before curved reflector, and curved reflector again alters course the light of injecting from pin hole to converge.
2. reflection-type pinhole photographic lens according to claim 1, is characterized in that curved reflector is comprised of micro reflector array, and the angle of each micro-reflector is different, makes its light reflection that just pin hole can be come to direction initialization.
3. reflection-type pinhole photographic lens according to claim 1, is characterized in that imageing sensor is positioned in the light path again converging, direct exposure imaging.
4. reflection-type pinhole photographic lens according to claim 1, is characterized in that, at the cross-over again converging, one unthreaded hole is set, and can be controlled to image sharpness by changing unthreaded hole size.
