However, in the previous photos, the old photos are stored in a negative film mode, and as time goes on, the photos are more easily lost and distorted, are unfavorable for long-term storage, occupy large space and cannot meet the current use requirements. The old negative film is scanned and converted into a digital mode to be stored by using the scanner, so that the defects of inconvenience for long-term storage and large occupied space are overcome.
However, when a roll of negative film is scanned prior to scanning, the negative film is first cut into, for example, every 6 cells and then scanned by a scanner. That is, when the scanning of the negative film is completed, the original roll of negative film is cut off every 6 cells, for example, and the cut negative film is returned to the customer after the scanning is completed. Compared with a continuous roll of negative film, the cut negative film damages the original negative film of the customer, and the cut negative film is scattered, so that the subsequent storage of the customer is not facilitated, and the sequence of scanned images is likely to be disturbed when the subsequent customer wants to scan again. Further, the operation of cutting the negative film and then placing it into a scanner for scanning is troublesome, and the negative film cannot be scanned continuously, so that the efficiency is low.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In one embodiment, as shown in fig. 1, the negative 41 scanning method includes the following steps:
s1: identifying whether a negative 41 is loaded into the scanner;
Wherein, a mounting cavity 4 is provided on the scanner, and a protrusion (not shown) is provided on a sidewall of the mounting cavity 4 for fixing the negative 41. When a roll of the negative 41 is loaded into the scanner, the protrusions are snapped into the spool of the negative 41, thereby securing the negative 41 within the mounting cavity 4.
Further, a detecting mechanism (not shown) is provided in the mounting cavity 4, and in one embodiment, the detecting mechanism is a first sensor, and the first sensor is used to identify whether the negative 41 is mounted in the scanner. In another embodiment, the detecting mechanism is a knob, and when the negative 41 is properly loaded into the scanner, the knob is moved to a predetermined position, and whether the negative 41 is loaded into the scanner is identified by determining whether the knob is moved to the predetermined position.
S2, performing S2; if yes, starting the scanner, and driving the negative film 41 and the transmission mechanism 5 to rotate towards a first direction;
Wherein, the scanner is electrically connected to a computer, and if the first sensor detects that the negative film 41 is loaded into the scanner, the computer controls to start the scanner according to the detection result, drives a motor to start rotating in a first direction, and drives the negative film 41 and the transmission mechanism 5 to rotate in the first direction through a gear, so that the film head of the negative film 41 moves towards the scanning table 31. As shown in fig. 2 and 3, the first direction is clockwise. The scanner is provided with the negative 41, the guide slope, the conveying mechanism 5, the base 3 and the spiral channel 61 in this order from left to right. The transmission mechanism 5 includes a main shaft 52 and a driven shaft 51 symmetrically disposed in the up-down direction, and the main shaft 52 is located at the bottom of the driven shaft 51. The negative 41 rotates in a first direction and enters the guide slope under the driving of the motor, and the negative 41 enters the gap between the main shaft 52 and the driven shaft 51 along the guide slope under the guiding action of the guide slope. Since the main shaft 52 also rotates in the first direction, after the negative film 41 enters the gap between the main shaft 52 and the driven shaft 51, the main shaft 52 cooperates with the driven shaft 51 to drive the negative film 41 to move toward the base 3.
Further, the spindle 52 and the driven shaft 51 have a plurality of through holes 511 formed in the shaft wall thereof. The controller controls the ventilation in the transmission mechanism 5 according to the first wind speed, and discharges wind from the through hole 511, so as to blow away the dust on the negative film 41, and prevent the dust on the negative film 41 from affecting the scanning result of the negative film 41, so that the result has a large error, and therefore, the main shaft 52 and the driven shaft 51 not only can move the negative film 41, but also can be used as a cleaning structure of the scanner to clean the negative film 41.
S3: detecting whether the negative film 41 reaches a preset position, if so, starting a first light source;
Wherein, one end of the base 3 near the spiral channel 61 is provided with another detecting mechanism near the entrance of the receiving cavity 6, and in an embodiment, the detecting mechanism is a second sensor for detecting whether the negative film 41 reaches a preset position. The top of the base 3 is provided with a scanning table 31, the distance from one end of the scanning table 31, which is close to the spiral channel 61, to the inlet of the accommodating cavity 6 is the length of the film head of the negative film 41, the film head length of the negative film 41 is about 1-3 images, the second sensor is preset at the position of one end of the base 3, which is close to the spiral channel 61, which is close to the inlet of the accommodating cavity 6, so that when the film head of the negative film 41 reaches the preset position, the first image of the negative film 41 is located on the scanning table 31. Whether the negative 41 reaches the preset position is detected by the second sensor, and the accurate positioning of the negative 41 can be met to a certain extent. When the second sensor detects that the negative film reaches a preset position, the controller controls the first light source to be started.
S4: control the negative 41 and the transport mechanism 5 to stop rotating, and control the positive electrode positioning member 2 to move downward;
The scanner comprises a camera 1, a positive positioning piece 2 and a base 3 which are sequentially arranged from top to bottom, wherein the positive positioning piece 2 is connected with the camera 1 and sleeved on the outer side of the camera 1, the bottom of the positive positioning piece 2 is made of transparent glass material, so that the camera 1 can scan a negative film 41 through the bottom of the positive positioning piece 2, and the positive positioning piece 2 can move up and down.
If the second sensor detects that the negative 41 has reached the preset position, the controller controls to stop driving the motor, thereby stopping rotation of the negative 41 and the transport mechanism 5. The controller controls the positive electrode positioner 2 to move downward toward the scanning stage 31 until the positive electrode positioner 2 moves against the scanning stage 31. After the positive positioning piece 2 moves to reach the scanning table 31, the positive positioning piece 2 compresses the negative 41, which is favorable for fixing the plane of the negative 41, preventing focusing blurring and ensuring the accuracy of the scanning process of the negative 41 scanning device.
S5: if the positive positioning piece 2 moves to reach the scanning table 31, the camera 1 is started to collect and scan the negative film 41, and the collected and scanned data is converted into a digital image for storage after being processed by a preset image processing algorithm;
The base 3 is located below the camera 1 and the positive positioning member 2, a first light source 32 is disposed in the base 3, the first light source 32 is located below the scanning table 31, the scanning table 31 is made of transparent glass material, and the first light source 32 can penetrate through the scanning table 31. After the positive positioning member 2 moves to reach the scanning table 31, the camera 1 starts to start, and the camera 1 starts to perform collection scanning on the negative 41, and when the scanner works, the first light source irradiates light on the negative to be input to generate reflected light (reflection manuscript) or transmitted light (transmission manuscript) representing image features. The optical system collects the light rays and focuses the light rays on the CCD, the CCD converts the light signals into electric signals, the circuit part performs A/D conversion and processing on the electric signals to generate corresponding digital signals, and the digital images are stored in the computer.
After the scanning is completed, whether the scanned image is complete is judged by whether the two ends of the stored digital image are obvious boundary lines or not. In an embodiment, the length and width of the positive electrode positioning member 2 are 1.2-1.5 times that of the scanning table 31, so as to ensure that the scanned image is complete, and finally, the two end boundaries of the stored digital image are cut by an image processor on a computer.
Further, the two side walls of the positive electrode positioning member 2 are provided with the second light source, and the minimum brightness value of the second light source is smaller than that of the first light source. In an embodiment, the computer calculates the brightness information of the digital image, and if the brightness of the digital image is smaller than a preset threshold value, the controller controls the second light source to be started, so that insufficient brightness is avoided, and the digital image is prevented from being too dark, and the quality of the digital image is influenced. And if the brightness of the digital image is greater than a preset threshold value, turning off the first light source, and starting the second light source to prevent the digital image from being over-bright.
In an embodiment, the brightness of the second light source is adjustable, and the controller controls the brightness of the second light source. When the brightness of the second light source needs to be adjusted, the brightness of the second light source is set in a controller. After the positive positioning piece 2 flattens the negative film 41, the controller starts the second light sources on two sides of the positive positioning piece 2, and after the second light sources emit specified brightness, the camera 1 scans, so that the brightness problem during scanning the negative film 41 is solved.
In an embodiment, sampling is performed according to a preset time interval, salt and pepper denoising is performed on the stored original digital image, a processed image is obtained, the difference between the original digital image and the digital image after the salt and pepper denoising is compared and counted, if the difference is greater than a threshold value, the image is considered to be interfered, ventilation is performed according to a second wind speed, wind power is increased to blow away the dust on the negative film 41, and the dust on the negative film 41 is prevented from affecting the scanning result of the negative film 41, so that the definition of the digital image is improved. If the difference is smaller than the threshold value, the interference on the picture is considered to be smaller, and the first wind speed is adjusted back, so that energy waste is prevented. Moreover, by setting the preset time to sample at intervals, energy can be further saved compared with continuous sampling.
S6: controlling the positive electrode positioning piece 2 to rise to a preset position;
after the digital image is stored, the controller controls the positive positioning piece 2 to move upwards to a preset position, so that the negative 41 is prevented from being moved due to the fact that the positive positioning piece 2 is always pressed against the negative 41.
S7: judging whether the negative 41 is completely scanned, if not, driving the negative and the transmission mechanism to continuously rotate towards a first direction, enabling the negative to move a preset distance, executing S4, and if yes, executing S8;
In one embodiment, a counter may be used to determine whether the negative 41 has been completely scanned. The counter accumulates the number of images that can record the scanned negative 41, and determines whether the negative 41 has been completely scanned based on whether the number of images of the scanned negative 41 is equal to the total number of images of the negative 41.
If not, the motor is driven to continue rotating in the first direction, thereby causing the negative 41 and the transport mechanism 5 to also continue rotating in the first direction. After the film head of the negative 41 moves toward the spiral path 61 by a predetermined distance s, the driving of the motor is stopped. One of the preset distances S is the length of one image of the negative 41, so that after the negative 41 moves by one of the preset distances S, the next image of the negative 41 just moves onto the scanning stage 31, then the motor is stopped to prevent the negative 41 from continuing to move, and then S4 is performed back. Wherein each time the driving time t of the motor=the preset distance s/the rotational speed v of the motor. The distance the negative film 41 moves is controlled by controlling the rotational speed v and the driving time t of the motor. The motor can maintain a constant rotation speed v, and can also input the required rotation speed v according to actual needs, and the motor is not limited in this regard.
Further, the spiral channel 61 is provided in the receiving chamber 6, and the spiral channel 61 is a continuous channel for receiving the negative film 41. The top of the spiral channel 61 is provided with an arc plate 611, the arc plate 611 is higher than the base 3, so that the negative film 41 can be prevented from being separated from the base 3, the negative film 41 can enter the accommodating cavity 6, the arc part of the arc plate 611 can play a guiding role, and the negative film 41 is guided to move along the arc part of the arc plate 611 and enter the arc channel, so that the scanned negative film 41 is accommodated in the accommodating cavity 6. The negative 41 is not required to be manually inserted into the spiral channel 61, and the negative 41 can be automatically rolled into the spiral channel 61, so that the negative 41 is prevented from being directly contacted by hands, sweat stains and the like on hands of people are prevented from polluting the negative 41, and the scanned digital image has low definition.
If it is determined that all scanning of the negative 41 is completed, S8 is executed.
S8: the negative 41 is rewound.
If it is determined that all the negative 41 has been scanned, the motor drives the negative 41 and the conveying mechanism 5 to rotate in a second direction, which is opposite to the first direction, as shown in fig. 2 and 3, and the second direction is a counterclockwise direction, that is, the negative 41 is rewound, and the negative 41 is removed from the spiral channel 61, so that the scanned negative 41 is rewound into the mounting cavity 4; thus, the negative 41 is returned to the pre-scanning state, which is convenient for storage.
According to the technical scheme, the old negative film 41 is scanned and converted into a digital mode to be stored, so that distortion caused by frequent flip exposure and environmental humidity of the old photo can be prevented, long-term storage can be facilitated, and the storage space can be saved. During the scanning process of the negative film 41, before the first image of the negative film 41 starts to be scanned, the detection mechanism detects whether the negative film 41 reaches a preset position, so that whether the first image of the negative film 41 reaches the scanning table 31 is accurately judged, and the first image of the negative film 41 does not need to be manually pulled to the scanning table 31. After the first image of the negative film 41 is scanned, the second image of the negative film 41 reaches the scanning table 31 by controlling the negative film 41 to rotate towards the first direction and controlling the negative film 41 to move by one preset distance, the second image of the negative film 41 does not need to be manually pulled to the scanning table 31, and the second image of the negative film 41 is controlled to reach the scanning table 31 by controlling the length of the distance moved by the negative film 41. And so on, by controlling the negative 41 to continue rotating in the first direction and moving by the preset distance, the next image of the negative 41 reaches the scanning stage 31, and scanning is started again. According to the technical scheme, the specific position of the negative film 41 is not required to be judged manually, the negative film 41 is not required to be manually moved, the degree of automation is high, the labor cost is saved, and inaccuracy in scanning due to manual judgment errors is avoided. Further, during the scanning process, if some dust is on the negative film 41, the scanning result of the film is easily affected, and the result has a large error. The negative film 41 is cleaned by ventilating the main shaft 52 and the driven shaft 51 and flowing out the wind from the through hole 511, thereby having good dust blowing and heat radiation effects. The cleaning force can be adjusted by adjusting the wind speed, so that the definition of the scanned digital image is ensured; in addition, in the rewinding process, dust removal operation can be performed on the negative film, so that the negative film is prevented from being damaged due to the fact that miscellaneous dust is involved.
