Description
Technical field
The utility model relates to optics and camera technique field, is specially a kind of negative film retreader.
Background technology
Usually, people putting forward tradition or professional slr camera is made a sightseeing tour, green grass or young crops is adopted in the countryside or news gathering and editing after, can at once take the shop for developing and printing to film (being egative film) and develop and print out, have this moment partly friend to scan the into permanent preservation in computer the inside to photograph again.But through developing and printing and scan two steps, the quality of photograph is had a greatly reduced quality already, and the heart that the people is appreciated pauses and loses somewhat.In addition, the egative film resting period that traditional camera is taken is long can wear out unavoidably, flavescence even mouldy, can not accomplish permanent preservation.
Though, the huge impact that digital camera brings for traditional film camera, traditional camera relies on its proven technique, image quality preferably, the advantage of aspects such as reasonable price still is subjected to doting on of part photography fan deeply.Yet As time goes on general egative film can " wear out " gradually, and flavescence even mouldy easily is naturally this becomes one of fatal weakness of traditional camera.
Become possibility for the works of traditional camera " are remained youthful forever ", professional negative film scanner occurred, it can solve the deficiency of the above traditional camera egative film to a certain extent, but price is more expensive, just generally can use in the shop for developing and printing of specialty.Though present many home-use flat bed scanners also add the support to the film scanning function, its actual scanning weak effect, volume is big, and needing could be relatively more perfect by image effect after the processing of software.
The utility model content
The purpose of this utility model is the deficiency at present traditional camera egative film treatment facility function, providing a kind of can be used with computer, the negative map picture directly can be changed into digital photograph and deposit computer, the negative film retreader economic, practical, simple to operate, that function is professional in.
The utility model is achieved through the following technical solutions: negative film retreader, comprise image sensing device, mainboard support, backlight, shell and drain pan, and the mainboard support is installed on the drain pan, and the mainboard support is outside equipped with shell, and shell and drain pan are connected and fixed; The image sensing device is installed on the mainboard support, and the drain pan of image sensing device camera lens correspondence is provided with backlight.
Described image sensing device comprises camera lens, lens mount and mainboard, and mainboard is fixed on the mainboard support, and lens mount is welded on the mainboard, and camera lens is installed in the lens mount.
What be provided with in the described camera lens can be OV550 master chip and OV5610 sensitive chip.
Described backlight top can be provided with movable film holder.
Described shell and film holder junction can be provided with baffle plate.
Can be provided with translucent cover on the described backlight.
Described shell top can be provided with trim, can be provided with power switch button and power light in the trim, and power switch button is connected with power switch on the mainboard.
Can be provided with USB interface on the described drain pan, USB interface realizes the power supply supply to backlight and mainboard, and the function of the camera lens image data transmission of gathering to the computer.
Can be provided with balancing weight in the described drain pan, with enhancing stability.
Can be provided with slipmat on the described drain pan.
Camera lens of the present utility model adopts OV550 master chip and OV5610 sensitive chip scheme, realizes 35MM egative film renovation function, and it has following beneficial effect: by connecting computer, carrying out the reproduction of 35MM tradition egative film, is the BMP form with the picture compression after the reproduction; Carry out data transmission and electric current supply by USB2.0, need not external power supply; Portable band is convenient in the ultra-small volume design; The outward appearance lines are succinct; Manually the control egative film need not mechanical assist device; Economic, practical, simple to operate, function is professional.The utility model has reached and need not spend higher cost and stand-by period and handle your photo to professional video shop, just can be in and share the process and the happiness of life drop record with the household.

Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
The utility model negative film retreader principle of work is as follows: as shown in Figure 1, the many photo-sensitive cell points that taken on the chip OV5610/5620 light-sensitive surface of negative map picture in camera lens are converted to light signal; Photosignal is converted to electricity (simulation) signal by the photoelectric commutator of chip the inside, and electric signal is converted to the RGB digital signal through A/D converter; The RGB digital signal becomes the yuv format signal through the ISP processor processing; The yuv format signal is packaged into unified computer through OV550 chip UVC coding can discern USB 2.0 picture signals; Picture signal is passed to computer through the USB line, so computer just can imaging; Computer obtains view data after hold drive software to carry out the mirror image optimization process later, so auto-mending has just obtained clearly picture.In order to provide stable power to negative film retreader, be provided with stabilivolt, the voltage that stabilivolt provides has 3.3v, 2.8v﹠amp; 1.8v, 3.8v$1.8v and 5v.The programmed control internal memory that is provided with is with temporary transient storage data.
