CN103327031A - Method for analyzing RAW format image file protocol stream based on MTP (Mail Transfer Protocol) - Google Patents

Abstract

The invention discloses a method for analyzing a RAW format image file protocol stream based on an MTP (Mail Transfer Protocol). The method comprises the following steps: S1: receiving an MTP data stream from a single lens reflex; S2: judging whether the received MTP data stream is a RAW format or not; if the format is not the RAW format, directly displaying; if the format is the RAW format, turning to a step S3 to continually process; S3: reading the MTP data stream; S4: carrying out RAW analysis on the read data stream; S5: generating a format file capable of being recognized by an intelligent cell phone system; and S6: displaying a newly-generated file with the format which can be recognized by the intelligent cell phone system. According to the method disclosed by the invention, an intelligent cell phone and the single lens reflex are connected with the intelligent cell phone through a USB (Universal Serial Bus) data line to analyze the RAW format data stream in real time, so as to realize the function of checking and editing the RAW format stored in the single lens reflex on the intelligent cell phone.

Description

A kind of method of resolving RAW format-pattern file protocol stream based on MTP

Technical field

The present invention relates to a kind of method of resolving RAW format-pattern file protocol stream based on MTP.

Background technology

Slr camera more and more is subject to liking of general public with its outstanding image quality and abundant reprocessing effect.Its picture is preserved with the RAW form usually.The RAW form is raw image files, is also sometimes referred to as digital egative film, because they serve as the role identical with motion picture negation, is not directly to use as image, but creates an image that comprises all information.The purpose of original image form be protect stored loss drop to minimum, for post-processed provides complete information.

The preview of general RAW form, reprocessing need to be finished by the software that PC is installed specific support RAW format analysis.

And the in recent years development of smart mobile phone is swift and violent, its operational capability is powerful, interconnecting function abundant, and portable convenient is if can couple together smart mobile phone and slr camera, replace in the past the work to the RAW format analysis processing that need to finish in PC, will for the user bring greatly convenient.

Summary of the invention

The object of the invention is to overcome the deficiencies in the prior art, providing a kind of is connected with slr camera smart mobile phone by the usb data line, based on the MTP host-host protocol, real time parsing RAW format stream data on smart mobile phone reach a kind of method of resolving RAW format-pattern file protocol stream based on MTP of function of checking and editing the picture of the RAW form of storing in the slr camera at smart mobile phone.

The objective of the invention is to be achieved through the following technical solutions: a kind of method of resolving RAW format-pattern file protocol stream based on MTP, it may further comprise the steps:

S1: from slr camera, receive the MTP data flow;

S2: judge whether the MTP data flow that receives is the RAW form, as not being that the RAW form then directly shows, if the RAW form then changes step S3 over to and continues to process;

S3: read the MTP data flow;

S4: the data flow that reads is carried out RAW resolve;

S5: the formatted file that generation can be identified by intelligent mobile phone system;

S6: the file of the form that can identify newly-generated intelligent mobile phone system shows.

The invention has the beneficial effects as follows:

The present invention can be connected with slr camera smart mobile phone by the usb data line, based on the MTP host-host protocol, and real time parsing RAW format stream data on smart mobile phone, reach the function of checking and editing the picture of the RAW form of storing in the slr camera at smart mobile phone, so that check that the photo of browsing and processing in the slr camera is more efficient and convenient.

Fig. 1 is schematic diagram of the present invention.

Embodiment

Below in conjunction with accompanying drawing technical scheme of the present invention is described in further detail: as shown in Figure 1, a kind of method of resolving RAW format-pattern file protocol stream based on MTP, it may further comprise the steps:

S1: from slr camera, receive the MTP data flow;

S2: judge whether the MTP data flow that receives is the RAW form, as not being that the RAW form then directly shows, if the RAW form then changes step S3 over to and continues to process;

S3: read the MTP data flow;

S4: the data flow that reads is carried out RAW resolve;

S5: the formatted file that generation can be identified by intelligent mobile phone system;

S6: the file of the form that can identify newly-generated intelligent mobile phone system shows.

Claims (1)

1. method of resolving RAW format-pattern file protocol stream based on MTP, it is characterized in that: it may further comprise the steps:
