Background technique

At present, a general programmer includes a transmission interface, a reading device, a buffer memory, a writing device, and a film advancing and retreating device. The transmission interface generally adopts IDE (Integrated Device Electronics), SCSI (Small Computer System Interface) or USB (Universal Serial Bus) as the transmission interface. If the IDE or USB interface is used, the operating system can directly detect the driver related to the installation. If the programmer uses SCSI as the data transmission interface, you must pay attention to the ID of the SCSI device during installation to avoid resource conflicts on the hardware. In terms of the design of the film advance and retreat device, the tray-type design is generally more common. There is an emergency film eject hole, film eject button, volume adjustment button, play/fast forward button and headphone jack on the panel. In the design of the lights, there are two lights, which respectively indicate whether the writer is currently programming or is in idle state, allowing users to understand the status of the writer more clearly. In addition, on the connection slot on the back, there are slots for DC power supply, transmission interface connection slot, jumper device and analog signal output.

As for the general card readers currently on the market, they are card readers that can read Compact Flash Card, SmartMedia Card, SD/MMC Card, or Memory Stick, or can read most of the above-mentioned memory cards at the same time. Card reader for memory cards. However, whether it is to read a single type of memory card or can read a variety of memory cards, the common point of the card reader is that it is connected to the computer through the USB interface, and then through the operation of the computer, the digital photo data is displayed on the screen. Or further edit or access the digital photo data.

Most importantly, in view of the current devices and methods for accessing digital photos taken by digital cameras and stored in memory cards, there is still considerable inconvenience. Its inconvenience is: in terms of digital photo access, most of the products on the market now use signal transmission lines to directly transmit the digital photos in the digital camera to the computer, and this method still requires the manufacture of the digital camera. The special signal transmission line attached by the manufacturer and the special digital photo reading software are used to read; in addition, most other reading methods use the card reader to transfer digital photos from the memory card through the USB transmission interface. Transfer to computer for editing or backup. In short, no matter which method is used, it must be processed by a computer. In terms of burning digital photos, if the accessed digital photos are directly burned into CDs with a general commercially available burner, the contents of the burned CDs are only individual digital photo files. Such digital photo files are It cannot be played on general VCD/SVCD/DVD players.

Regarding the burning operation of digital photos, the practice of known technology is to read the digital photos (including formats such as JPEG and TIFF formats) in the memory card through the card reader, and then use the burning machine of the computer peripheral to burn Backup to CD-ROM. However, the data stored in the optical disc in this way are just individual digital photo files one by one. The disadvantages of this approach are:

(1) This known burning disc cannot be played on a general DVD/VCD/SVCD player.

(2) According to this known recording method, the CD recorded by the recording method cannot produce animation during playback.

(3) According to this known recording method, the optical disc recorded by the recording method has no sound effect when played.

In addition, although commercial software can be used on the computer to make the digital photos in the memory card into VCD discs for static display, the disadvantages of this approach are:

(1) There is no dynamic picture between the two photos.

(2) There is no backup source file.

(3) Not directly input from the memory card.

(4) More expensive computer interface equipment and software must be purchased.

(5) Users must be familiar with computer operations.

(6) Since the digital data can only be burned into the CD by operating the computer connected to the burner, it is very inconvenient to carry or operate

Detailed ways

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 3, FIG. 3 is a flowchart showing the programming operation. The purpose of step 1 to step 5 described later is to burn into a CD that can be played on DVD/VCD/SVCD, and its follow-up step 6 to step 9 is then purely for the backup of digital photo data.

Step 1 is that the present invention starts the processing operation through the operation unit. In step 2, the card reading unit 101 reads the digital photos from the memory card 102 and stores them in the random access memory 108, and at the beginning, the central processing unit 200 calculates the number of digital photos read by the card reading unit 101. number of sheets. In step 3, the central processing unit 200 reads the sound file from the read-only storage unit 107 . Step 4 is to mix and generate animation files according to the digital photo files read in step 2 and the sound files read in step 3, and burn the mixed animation files into the CD.

Regarding step 4, it will be further subdivided here, and step 4 is subdivided into more detailed procedures, please refer to Figure 4.

First, step 4.1 in Figure 4 is the beginning of the programming process. In step 4.2, the central processing unit 200 further reads the digital photos that have not been decompressed from the digital photos that have been read from the memory card in step 2.

In step 4.3, the central processing unit 200 decompresses a single digital photo that has not been decompressed into YUV format according to the reading order, and temporarily stores it in the buffer area of the random access memory 108; It can be divided into two buffer blocks, one buffer block A stores the digital photos that have been mixed and edited, and the other buffer block B stores the decompressed digital photos that are ready to be used to generate animated images; when decompressed After the final digital photo is burned, it is moved from the buffer block B to the buffer block A, and in the subsequent steps, the newly decompressed digital photo can be stored in the buffer block B accordingly.

In step 4.4, the central processing unit 200 edits the digital photo decompressed into YUV format in step 4.3 and the previous decompressed digital photo of the digital photo into an animation file. The method is: by inputting the previous decompressed digital photo stored in the buffer block A and the newly decompressed digital photo stored in the buffer block B to generate an intermediate YUV format animation . For example, the previously decompressed digital photo stored in buffer block A is fixed, and then the newly decompressed digital photo stored in buffer block B is slowly shifted in, forming a two-YUV format files.

The function of step 4.5 lies in the mixing and compression of animation files and sound effect files. The central processing unit 200 mixes the animation composed of two YUV format files in step 4.4 and the sound file read in step 3 to generate an intermediate animation, and then compresses the mixed animation into an MPEG file. Its method can compress YUV format images into MPEG images according to ISO/IEC 13818-2 and ISO/IEC 11172-2 of MPEG1/MPEG2 specifications.

Step 4.6 is to use the burning unit 100 to burn the MPEG files mixed in step 4.5 into the optical disc. Step 4.7 is the end of the burning operation of the single decompressed digital photo.

Go back to Figure 3 and go to step 5. Step 5 is to judge whether all digital photos have been decompressed and burned in step 4. Then go back to step 4 to find and edit and burn the next digital photo that has not been decompressed. Otherwise, if step 5 confirms that all digital photos have been edited and burned in step 4, then enter step 6.

In step 6, the central processing unit 200 reads all digital photo files from the random access memory 108 . When step 7 is reached, at first the central processing unit 200 first sets up a subdirectory of digital photos, and is used for backing up all digital photos in the subdirectory. If it is in DVD format, UDF (Universal Disk Format) is used. Specifications, if it is in VCD or SVCD format, use the ISO9660 specification. Then read the digital photos that have not been burned back up one by one.

Step 8 is to burn the digital photos read in step 7 that have not been burned and backed up one by one. Step 9 is to check whether all the digital photos have been backed up. If not, go back to step 7 to continue. If the operation has been completed, then step 10 ends the overall burning operation.

According to a preferred embodiment of the present invention, after the user inserts the memory card 102 into the card reading unit 101 and inserts a blank disc into the burning unit 100, as long as the user presses the start key 106, the entire process can be automatically performed and completed.
