Description
The utility model belongs to the digital photography equipment, relates to a kind of high-performance special digital camera machine back of the body technical scheme.
The tradition Professional Photography, photo studio and advertisement photography company adopt film, film, and operational sequence is cumbersome, will considerable time choose picture from taking to getting sheet, and midway by punching, chip select is enlarged and print, and amplification is repaiied sheet and is waited and finish above work post, just can obtain picture.But effect is not photographer can be controlled comprehensively, in case occur any link carelessness midway, may bring the loss that can't remedy to photographer.Above operating equipment needs a bigger investment, and cost is higher, and environmental pollution is more serious.
At present, digital camera is to be positioned at a kind of home-use consumer electronics commodity abroad, deflection " fool's type " adopts automatic exposure in design, the mode of automatic focusing, generally adopt the JPEG compressed format of 24bit true color to store photo document, 1/3 (optimal mode) that compresses this former number size is to 1/8 (middle-grade pattern).Can't amplify making, photographic quality is poor, and sharpness is not enough.From imaging process, key is the integrated number of CCD (abbreviation of English CHARGECOUFLIG DEVICE is a kind of photo-sensitive cell, is charge-coupled image sensor) and the quality of A/D equipment.This is the principal element of digital camera performance.Though product is being brought in constant renewal on the market, but being still of adopting is of a size of 2/3 cun CCD sensitive chip, and just increase as the number sum by reducing pixel dimension, increase so only understand the comparison film resolving power, and color rendition and light sensitivity adjusting aspect do not improve a lot.The photo studio camera of specialty relatively, resolution only reaches 6,000,000 pixels a few days ago, and general digital camera has only 100-200 ten thousand pixels, and also has some sweep type machines back ofs the body, though that pixel can reach is several ten million, can not be used for the photo studio portraiture photography.Because the time shutter is very long, only be applicable to the still life shooting.
What traditional camera adopted is film, light reaching the film, will be through dark place operation and silver salt flushing, and greatest problem is to carry out in-line processing, carries out the later stage compilation image, though general digital camera can link with computing machine, but existing problems, operate cumbersomely, the electronic simulation information that obtains on the electrooptical device is amplified the A/D conversion process, and the digital image information of the best is stored on random access memory (storage card) or the disk, use these data of Computer Processing again.
The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of full manual operation of traditional camera that both kept is provided, and accomplishes need not film again, increases economic efficiency greatly and reduces environmental pollution.And image can be filmed with digital form, directly be recorded in the computer, can carry out the later stage compilation image and, all reach the traditional photography effect, in the level of detail performance, surpass the image picture under the traditional approach in color rendition and degree of saturation with various digital form outputs.
The purpose of this utility model is achieved by the following technical solution, the digital camera machine back of the body, comprise casing, sensitive chip and circuit, sensitive chip is positioned at the casing front end, the components and parts that it is characterized in that circuit comprise sensitive chip connecting circuit plate, optical charge be coupled digital imaging processing computing circuit plate, digital signal output circuit plate, data delivery line, programmed control line and power lead, and each components and parts is connected in the circuit.Image is noted with digital form, image can be recorded in the computer with digital form by high-speed transmission line and high speed card again, with realization later stage compilation image with various digital form image output pictures.
Be coupled digital imaging processing computing circuit plate and digital signal output circuit plate of the described digital camera machine back of the body, sensitive chip, sensitive chip connecting circuit plate, optical charge arranged successively.Picture signal is converted into digital signal.
The described digital camera machine back of the body, the size of sensitive chip reaches 2.5 inches.Replaced 120 traditional films with the CCD electronics machine back of the body and come imaging, obtained high resolving power with overlarge area CCD face battle array, actual photosensitive area is greater than common egative film.
The described digital camera machine back of the body, casing is provided with and the camera body coupling arrangement, power supply control interface, computer program interface and computer data interface.Being connected of realization and camera body, computer, power supply.
The described digital camera machine back of the body, the digital camera machine back of the body is wholely set with computer or is provided with respectively.Consider the microminiaturized ability of digital camera use occasion and computer, the digital camera machine back of the body can be wholely set with computer
This digital camera machine back of the body has adopted ULCCD ULTRA LARGE CCD technology, and by the CCD device, the light that the digital camera machine back of the body transmits camera lens converts electric signal to, converts digital signal to by A/D again and delivers to storage unit and preserve.The CCD number has determined the size of each pixel, and the sum of CCD is many more, and image quality is good more.
This digital camera machine back of the body has following characteristics:
(1) the digital camera machine back of the body can be directly installed on the 120 mm professional camera special fuselages, carries out digital photography, has saved that former operation fixes the film, the egative film expense, has avoided problems such as a series of cumbersome work such as post-production and environmental pollution.
(2) digital camera machine back of the body technology has reached high resolution and light sensitivity, and precision is up to 1,000 ten thousand pixels, and the numerical digit mode that inner employing is 42 is handled, and output format is 36 very color files, can reach the extremely wide density of 3.6D.Can directly amplify and export jumbo picture to, aperture time is 1/8000 second to 64 seconds, and 16 grades of light sensitivity are adjustable, are the single exposure imaging-type, can use flashlamp simultaneously.All reach the traditional photography effect in color rendition and degree of saturation, in the level of detail performance, surpass the color record under the traditional approach.Can satisfy the professional photographer fully wedding photo, seal pre-treatment and other logarithmic code images are had required widespread use.It can allow the captured image of photographer, and no matter wedding gauze kerchief or advertisement picture to a high-profile or low-key (texture of White Dress), show more saturated color and rich details level more.This technology, can every continuous shooting speed of 0.3 second take 60,000,000 files, this is the fastest continuous shooting speed of the present 120 digital machines back ofs the body in the world and the higher precision of images, has filled up domestic and international blank, will bring great economic benefit to the owner who invests big-and-middle-sized digital photo studio both at home and abroad.
