Description

Real-time image transmission and preview system and its transmission and preview method

technical field

The invention relates to an instant image transmission and preview technology, in particular to an instant image reception and preview system and its transmission and preview method.

Background technique

Please refer to Fig. 1, it is an existing image transmission and preview system 700, including a scanner 701, computer equipment 702 and memory card 703, the scanner 701 has a memory card access device 7010, and the computer equipment 702 includes a computer host 7020 and a display 7021 , the host computer 7020 is provided with a memory card access device 7022 .

When the image transmission and preview system 700 is in operation, the user must insert the memory card 703 into the memory card access device 7010 of the scanner 701 in advance. After the scanner 701 scans, the scanned image is recorded in the memory card access device 7010 Afterwards, the user must pull out the memory card 703 from the memory card access device 7010 of the scanner 701, and then insert the memory card 703 into the memory card access device 7022 of the computer host 7020, and the computer host 7020 passes The memory card access device 7022 reads the scanned image in the memory card 703 and displays the scanned image on the display 7021 .

This kind of image transmission and preview system 700 must wait for the scanner 701 to finish scanning, then dump the scanned image through the memory card 703, and finally read the scanned image in the memory card 703 through the host computer 7020 to display the scanned image on the monitor 7021 on. This method not only has complicated steps, is time-consuming and labor-intensive, but also cannot perform real-time preview while scanning the image. It is necessary to wait until the scanner 701 finishes scanning to know whether the image is correct.

Please refer to Fig. 2, which is another existing image transmission and preview system 800, which includes a scanner 801, computer equipment 802 and short-distance transmission cable 803, and the computer equipment 802 includes a computer host 8020 and a display 8021, and a short-distance transmission line The cable 803 connects the scanner 801 and the host computer 8020 . The short-distance transmission cable 803 can be a USB cable or an RS-232 cable or the like.

When the image transmission and preview system 800 is in operation, after the scanner 801 finishes scanning, the scanned image will be transmitted to the host computer 8020 via the short-distance transmission cable 803, and the host computer 8020 will read the scanned image and display the image on the display 8021 superior.

Although this image transmission and preview system 800 saves the step of inserting and pulling out the memory card, it still has to wait until the scanner 801 completes the scan, and then transmit the scanned image to the host computer 8020 via the short-distance transmission cable 803, and finally via the host computer 8020 The scanned image is read to be displayed on the display 8021. In this method, not only must the scanner 801 and the computer equipment 802 be set within the range where the short-distance transmission cable 803 can be connected, but also it is impossible to perform instant preview while scanning the image, and the image cannot be known until the scanner 801 completes scanning. is it right or not.

Please refer to Fig. 3, it is another kind of existing image transmission and preview system 900, including scanner 901, computer equipment 902 and wired network equipment 903, computer equipment 902 includes computer mainframe 9020 and display 9021, wired network equipment 903 connects scanning Instrument 901 and computer host 9020. The wired network device 903 can be a local area network or the Internet.

When the image transmission and preview system 900 is in operation, after the scanner 901 scans, the scanned image will be sent to the host computer 9020 via the wired network device 903, and the host computer 9020 will read the scanned image and display the image on the monitor 9021.

Although the image transmission and preview system 900 has improved the restrictions on the installation positions of the scanner 901 and the computer equipment 902, it still has to wait until the scanner 901 finishes scanning, then transmit the scanned image to the computer host 9020, and finally read it through the computer host 9020 The image is scanned to display the image on the display 9021. In this method, real-time preview cannot be performed while the image is being scanned, and it is necessary to wait until the scanner 801 finishes scanning to know whether the image is correct.

Please refer to FIG. 4 and FIG. 5 , the real-time image transmission and preview system 100 of the present invention is applied in a wireless network, such as a WiFi network. The real-time image transmission and preview system 100 of the present invention includes a scanner and a wireless device, and the wireless device includes a desktop computer 2 , a mobile phone 3 , a notebook computer 4 , and an e-book 5 . In the embodiment of the present invention, the scanner can be a hand-held scanner 1 , the wireless device can be an e-book 5 , and the hand-held scanner 1 and the e-book 5 can be connected to each other via a WiFi network. In actual implementation, any electronic device with wireless function can be used to replace the e-book 5 .

The handheld scanner 1 has a scanning module 10, a first processor 11, and a first memory 12. The handheld scanner 1 can be connected to a wireless adapter 13 to transmit and receive data via wireless signals. The electronic book 5 has a display module 50, A second processor 51 , a second memory 52 and a wireless module 53 . The scanning module 10 can scan documents in multiple linear scans along one direction. The first processor 11 is used to control the operation of the hand-held scanner 1. The first memory 12 is used to store the operation data and scanning data of the hand-held scanner 1. image data.

The wireless module 53 is used to receive image data, the second memory 52 is used to store the received image data, the second processor 51 is used to control the operation of the electronic book 5 , and the display module 50 is used to display the received image. In actual implementation, the wireless adapter 13 can be a USB wireless adapter for converting USB signals into WiFi signals, and the wireless module 53 of the electronic book 5 can be a WiFi module.

When the real-time image transmission and preview system 100 is in operation, the first processor 11 of the hand-held scanner 1 controls the scanning module 10 to scan the document in multiple linear scans along a direction. For example, the scanning module 10 gradually scans the document from the top to the bottom of the document in a linear scanning manner, the scanning module 10 can scan a part of the document at a time, and the scanning module 10 can scan the entire document after multiple scans.

After the scanning module 10 performs a linear scan, the first processor 11 stores the scanned part of the image in the first memory 12 , and transmits the part of the image to the wireless module 53 of the e-book 5 via the wireless adapter 13 .

After the second processor 51 detects that the wireless module 53 has received the partial image, the partial image is stored in the second memory 52, and then the second processor 51 reads and modifies the partial image so that the partial image conforms to the image display format, and finally , the display module 50 displays the modified partial image conforming to the image display format. Therefore, the real-time image transmission and preview system 1 of the present invention can realize the functions of real-time scanning and real-time preview. In addition, when the above-mentioned operations are repeatedly executed, when the scanning module of the hand-held scanner 1 gradually completes scanning, the display module of the electronic book 5 50 also gradually reveals the complete image.

Please refer to FIG. 6 to FIG. 9 and the following table 1, the real-time image transmission and preview method 6 of the present invention can be burned in the first memory 12 and the second memory 52 in the form of software, and the first processor 11 and the second processor 51 can Read the first memory 12 and the second memory 52 respectively and execute the software to realize the instant image transmission and preview method 6 .

The instant image transmission and preview method 6 of the present invention includes an instant image transmission method 60 applied to the palm scanner 1 and an instant image preview method 65 applied to the e-book 5 . Referring to Fig. 8, instant image transmission method 60 comprises the following steps:

Step 600: When the handheld scanner 1 is turned on, the first processor 11 reads the data in the first memory 12 to control the operation of the handheld scanner 1 and start the instant image transmission function. When the handheld scanner 1 is in standby , the first processor generates a standby information packet. As shown in FIG. 7 and Table 1, the standby information packet has three fields, namely a code field, a length field and a data field. The code field of the standby information packet is written with 0X00, the length field is written with 0, and the data field is not written with any data. The standby information packet indicates that the handheld scanner 1 is in a standby state.

Step 601: The first processor 11 transmits the standby information packet to the wireless adapter 13, and sends the standby information packet via the wireless adapter 13 with a WiFi signal.

Step 602: The first processor 11 determines whether the scanning module 10 starts scanning. If the scanning module 10 has not started scanning, step 600 is repeated.

Step 603: If the scanning module 10 starts scanning, the first processor 11 generates a format information packet. The code field of the format information packet is written into 0X01, the length field is written into 1, and the data field can be written into corresponding values according to the scanning format. In this embodiment, the scanning format can be divided into four types: color high-resolution scanning, color low-resolution scanning, gray-scale high-resolution scanning and gray-scale low-resolution scanning, and the image compression format can choose JPEG compression technology, and the image size can be selected as The length is 10 inches and the width is 5 inches. According to the above four scanning formats, the data field can be written with four values of 0, 1, 2 or 3. This format packet indicates in which format the image will be scanned. When actually implemented, the image compression format and image size can be other widely used formats.

Step 604: The first processor 11 transmits the format information packet to the wireless adapter 13, and sends the format information packet via the wireless adapter 13.

Step 605: The first processor 11 determines whether the scanning procedure is interrupted. In actual implementation, the user can interrupt the scanning by pressing the button 14 on the casing of the handheld scanner 1 , or the scanning can also be interrupted when the first processor 11 detects an abnormality in the handheld scanner 1 .

Step 606: If the scan is interrupted, the first processor 11 generates an interrupt information packet, the code field of the interrupt information packet is written into 0X40, the length field is written into 0, and the data field is not written into any data. This interrupt information packet indicates The handheld scanner 1 is in the interrupted scanning state.

Step 607: The first processor 11 transmits the interruption information packet to the wireless adapter 13, and sends the interruption information packet via the wireless adapter 13. Afterwards, step 600 is repeatedly executed.

Step 608: If the scanning continues, the scanning module 10 scans part of the files sequentially in a linear manner.

Step 609: The first processor 11 calculates the number of scanned image bits and generates an image packet, and the code field of the image packet is written into 0X02. The length field is written into the number of bits of the scanned image, for example, when the number of bits of the scanned image is 256 bytes, the length field is written into 256. The data field is written to the scanned portion of the image.

Step 610 : The first processor 11 transmits the image packet to the wireless adapter 13 , and sends the image packet via the wireless adapter 13 .

Step 611: The first processor 11 judges whether the scanning is completed. If the scan has not been completed, step 605 is repeatedly performed.

Step 612: If the scan is completed, the first processor 11 generates a completion packet. The code field of the completion packet is written with 0XFF. The length field is written into the file header number of the scan format, for example, when the file header number of the scan format is 5 bytes, the length field is written into 5. The data field is written in the header data of the scan format.

In actual implementation, after step 612 is completed, step 600 may be repeatedly performed to continuously perform the instant image transmission function.

Referring to Fig. 9, the instant image preview method 65 includes the following steps:

Step 650: When the electronic book 5 is turned on, the second processor 51 reads the data in the second memory 52 to control the operation of the electronic book 5 and activate the instant image preview function, and the second processor 51 controls the wireless module 53 to receive the handheld Packet sent by Type Scanner 1.

Step 651: The second processor 51 reads the code field in the packet.

Step 652: The second processor 51 judges the code field. If the code field is 0X00, it means that the handheld scanner 1 is in standby state. At this point, step 650 is repeatedly executed.

Step 653: If the code field is 0X01, it means that the handheld scanner 1 has started the scanning procedure. At this time, the second processor 51 reads the data field in the packet.

Step 654: The second processor 51 judges the value in the data field. The second processor 51 can know the format of the scanned image by judging the value in the data field, and record the format of the image.

Step 655: The second processor 51 creates a memory space according to the value in the data field. That is, the second processor 51 establishes a memory space corresponding to the number of bits of the image format according to the image format.

Step 656 : The second processor 51 controls the wireless module 53 to receive the packet sent by the handheld scanner 1 .

Step 657: The second processor 51 reads the code field in the packet.

Step 658: The second processor 51 judges the code field. If the code field is 0X40, it means that the hand-held scanner 1 is in interrupted scanning state. At this point, step 650 is repeatedly executed.

Step 659: If the code field is 0X02, it means that the packet is an image packet. The second processor 51 reads the length field and the data field in the packet, and stores the image data in the memory space.

Step 660: The second processor 51 reads the image data stored in the memory space. During actual implementation, if the second processor 51 does not set up a memory space conforming to the number of digits of the image format according to the format of the image, but utilizes a fixed-capacity memory space to store image data, the second processor 51 can store image data according to the image format. The number of bits to read the latest image data that matches the number of bits in the fixed image space. For example, the fixed-capacity memory space can store an image with a length of 20 inches and a width of 8.5 inches, and the image format of the scanned image is 10 inches in length and 8.5 inches in width, then the second processor 51 will read the latest written length 10-inch, 8.5-inch wide image, and add an end code to the image so that the image can be displayed. In actual implementation, the image format of the scanned image can be in JPEG format. After the second processor 51 reads the latest written image with a length of 10 inches and a width of 8.5 inches, it will add an end code of FFD9 to the image to Make the image conform to JPEG format.

Step 661: The second processor 51 drives the display module 50 to display the latest image.

Step 662 : The second processor 51 controls the wireless module 5 to receive the packet sent by the handheld scanner 1 .

Step 663: The second processor 51 reads the code field in the packet.

Step 664: The second processor 51 judges whether the code field is 0XFF. If the code column is not 0XFF, step 658 is repeatedly executed.

Step 665: If the code field is 0XFF, it means that the handheld scanner 1 has finished scanning, that is, the image transmission has been completed. At this time, the second processor 51 reads the length field and the data field.

Step 666: The second processor 51 adds the header data in the data field to the image to form a complete image conforming to the format. Afterwards, the second processor 51 stores the image as a single image file, such as a JPEG file. After that, the instant image preview is complete.

In actual implementation, after step 666 is completed, step 650 may be repeatedly performed to continuously perform the instant image preview function.

To sum up, the real-time image transmission and preview system and its transmission and preview method 1 of the present invention can be used in wireless networks. In the case of preset scanning image format, each time the hand-held scanner 1 performs a status scan Afterwards, the part of the image can be sent to the e-book 5, and the e-book 5 can immediately receive the part of the image and display the part of the image in accordance with the preset scanning image format, so as to realize the function of real-time scanning and real-time preview.
