[0016] 2. It needs to consume a lot of Memory (storage medium) to save all the information related to the file Handle
[0017] 3. Generally speaking, the file name is the general identification of the file in the system, and it is often used as a parameter between modules. However, between the image device and the printing device, the file is identified by the file Handle, which must be specified when printing starts. Mapping file names and file handles, searching for all handle information, and this will also consume time

Embodiment Construction

[0047] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0048] figure 2It is a schematic diagram of the implementation process of the handle processing method under the PictBridge standard, as shown in the figure, the implementation may include the following steps:

[0049] Step 201, when the image device enters the PictBridge mode for file printing, the file Handle is transmitted to the printing device;

[0050] In this step, when the image device enters the pictbridhe mode, it can transmit the file Handle to the printer, so as to deceive the printing device to complete the initialization work; at this time, the Handle can be regarded as a virtual handle, because it is not related to the real one at this time. Because the Handle transmitted by the image device to the printing device in the prior art corresponds to a specific file, the Handle transmitted in this step is called a virtual Handle in the embod...

Abstract

The invention discloses a handle processing method and a device under a PictBridge standard, comprising the following steps: a file handle is transmitted to printing equipment when image equipment enters a PictBridge mode and carries out the file printing; after the image equipment determines the file required to be printed, a mapping relation between the file handle and the file required to be printed is established; furthermore, after the printing equipment transmits the file handle back to the image equipment, the data of the file required to be printed is transmitted to the printing equipment according to the mapping relation. The method and the device of the invention can improve the working efficiency of image printing under the PictBridge mode.

Description

technical field [0001] The invention relates to image printing technology, in particular to a handle processing method and device under the PictBridge standard. Background technique [0002] PictBridge is an industry standard established by CIPA (Camera & Imaging Products Association, Camera & Imaging Products Association), that is, digital images can be printed directly without using a computer. Under this standard, a camera phone or digital camera that supports the PictBridge standard can directly print out photos after connecting to a corresponding printing device. And no matter what kind of printing device model or manufacturer, as long as the printing device supports PrictBridge, it will have this function. This standard was established by CIPA and has been recognized as an industry standard by many manufacturers of digital cameras and printing equipment. [0003] The PictBride standard stipulates that the identification of a file between a camera and a printing devic...
