Description

Cloud image supply and demand method for digital publications

The invention relates to a cloud image supply and demand method, in particular to a cloud image supply and demand method for digital publications.

With the advancement and breakthrough of digital technology, the production process of digital publications has also undergone major changes, not only digitalizing the traditional manual finishing, color separation and pre-press operations, but also able to digitize the digital publications. The data is transmitted to digital printers in a variety of media (such as disk, CD, network transfer...) to output high-quality digital publications. Taking the digital publication resolution of 200dpi as an example, if you want to output an 8×10吋 digital publication, you need to prepare an image file of 1,600×2,000 pixels to output the best image quality.

However, for the pre-operation of editing images, the hardware performance of the personal computer will determine the speed and efficiency of editing the image, that is, the larger the image file capacity, the slower the processing speed and efficiency, and the current When a personal computer performs image editing, it often loads several or even dozens of image files. This is a considerable load on a personal computer with a hardware that is far less than the servo host.

For example, taking the digital camera of the current tens of thousands of pixels as an example, the original image size of each digital photo is 4,224×2,376 pixels, and the file size is between 200MB and 5MB depending on the storage format, and the current 19-inch screen is the best. The resolution is about 1280×1064 pixels. Obviously, for the screen, there is no difference in the image file for displaying 1280×1064 pixels or 4,224×2,376 pixels. For the 8×10吋 digital publication, the image file of 4,224×2,376 pixels is close to the threshold of 1,600×2,000 pixels, so how to improve the PC editing without affecting the quality of digital publications. The speed and efficiency of the image became the inventors of this case who actively thought about the problems they wanted to overcome.

In addition, in the field of video editing on the line, it is more important because of the limitation of the bandwidth of the network transmission and the limitation of the computing load of the servo end, and the operation and transmission mode of the large picture picture.

Accordingly, it is an object of the present invention to provide a cloud image supply and demand method for digital publications capable of improving image editing speed and efficiency under the premise of combining the quality of digital publications.

Therefore, the cloud image supply and demand method of the digital publication of the present invention is connected by a servo unit to an electronic device through the Internet. The image transmission method includes the following steps. Step 1: The servo unit uses at least the same board as the material. . Step 2: The serving unit generates a plurality of thumbnails whose pixels are smaller than the template and the pixels are different from each other according to the pixels of the template. Step 3: The servo unit acquires the resolution of a display screen of the electronic device through a webpage attached to the electronic device. Step 4: The SERVOPACK receives a request for the electronic device to download a template map. Step 5: The servo unit transmits a thumbnail of the pixel closest to the resolution to the electronic device according to the resolution, so that the electronic device displays the thumbnail.

The invention has the beneficial effects that the electronic device can only download and display a suitable thumbnail, and the speed of transmitting and editing the image between the servo unit and the electronic device can be improved without affecting the quality of the digital publication. With efficiency.

The above and other technical contents, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments.

Referring to FIG. 1 , FIG. 2 , FIG. 3 , and FIG. 4 , a preferred embodiment of the cloud image supply and demand method of the digital publication of the present invention is connected to the electronic network 2 by a servo unit 1 through a connection network. Web page 3 is executed. The electronic device 2 can be a computer, a personal digital assistant, a smart phone, etc. The following is a description of the steps in the following embodiments: Step 40: The servo unit 1 acquires an original image P', and determines the reduction of the same board image P relative to the original image P' according to the required size and resolution of the digital publication. proportion.

For example, the original image P' size is 4,224 × 2,376 pixels, the file size is between 200MB and 5MB depending on the storage format, and the pixel of the desired digital publication is 1,600×2,000 pixels, which is scaled proportionally. The pixel of the template map P is determined to be 3,555×2,000.

Step 41: The servo unit 1 uses the sample template P as the material for image editing.

Step 42: The SERVOPACK 1 calculates the number of reductions by 100%, 97.5%, 95%, 92.5%, 90% according to the pixel of the template P by equal difference operation. .10%, 7.5%, 5%, 2.5%, a plurality of thumbnails Pn whose pixels are smaller than the template P and whose pixels are different from each other are generated and stored in the servo unit 1.

Step 43: The SERVOPACK 1 is connected to the electronic device 2 via the Internet. In the preferred embodiment, the servo unit 1 interacts with the electronic device 2 in an eXtensible Markup Language (XML).

Step 44: The servo unit 1 embeds an image editing area 31 having an image editing function and a plurality of stackable template frames 32 through the webpage 3, and acquires the resolution of the display screen 21 of the electronic device 2. In the preferred embodiment, the image editing area 31 presents a book form and is capable of rendering a page turning effect of the 3D animation.

Step 45: The SERVOPACK 1 receives the request of the electronic device 2 to download the template P.

Step 46: The servo unit 1 transmits the thumbnail Pn of the pixel closest to the screen resolution to the template frame 32 according to the resolution of the display screen 21 of the electronic device 2, so that the display screen 21 of the electronic device 2 displays the Thumbnail Pn.

For example, the resolution of the template P is 3,555×2,000 pixels, that is, nearly 7.11 million pixels. When the resolution of the display 21 of the electronic device 2 can only display 1024×768 pixels, it only needs to provide a comparison with the template. P about 40% of the thumbnail Pn can satisfy the display requirement of the aforementioned display screen 21.

Step 47: The servo unit 1 records the markup language corresponding to each editing action in the image editing area 31 and the template frame 32.

Step 48: The SERVOPACK 1 receives the request for uploading the file by the electronic device 2, and determines that the editing operation is completed.

Step 49: The servo unit 1 according to the foregoing recordable extensible markup Re-edit the template P and produce a page page for digital publishing.

Therefore, if the servo unit 1 transmits the original image P' of 4,224×2, 376 pixels or the template image P of 3,555×2,000 pixels as the material to the electronic device 2, the compressed file (JPEG) is stored in size. Still up to 4MB, so for the most popular 2M/256 ADSL today, the upload rate per second is about 32 KB/sec, it takes at least 128 seconds to transfer the original image P' or the template P (4MB/ 32KB sec=4×1024KB/32KB sec=128sec). However, if the servo unit 1 transmits the thumbnail Pn of about 40% to the electronic device 2 as compared with the template P, the storage size is only 1.6 MB, so it takes only 51 seconds (1.6 MB). /32KB sec=1.6×1024KB/32KB sec=51sec).

According to the above description, the cloud image supply and demand method of the digital publication of the present invention has the following advantages and effects:

1. In the case that the display quality of the electronic device 2 is not affected, in the process of editing the image, only the thumbnail Pn is loaded and displayed, and only the thumbnail Pn is edited, so that not only the transmission can be provided. The speed of the time can greatly reduce the load of the electronic device 2, and improve the speed and efficiency of the electronic device 1 when editing images.

2. The present invention can quickly re-edit the template P generated according to the final result of the image editing area 31 with the hardware performance being much higher than that of the servo unit 1 of the electronic device 2, in accordance with the quality of the digital publication. A page file for a digital publication can be used to improve the editing speed and efficiency of the electronic device 2, and the quality of the digital publication is taken into consideration.

3, various scales of the thumbnails have been calculated and stored in advance, even if used In the zoom window, the servo unit 1 does not need to perform the thumbnail operation again in real time, and directly transmits the most suitable thumbnail image to the user, thereby effectively reducing the load amount calculated by the servo unit 1 and the electronic device 2.
