Yes, and corresponding devices have been developed. For example, a camera equipped with a communication function has been developed as a digital camera. In such a digital camera, captured image information is transmitted by e-mail (e-mail), FTP ((standard) file transfer protocol), and a unique protocol. Can be transmitted to a PC (personal computer), another digital camera, a server, or the like. At present, most communication from image processing devices is connected to a PC or printer, but in the future, communication between the same devices or between image processing devices within the range of the same manufacturer, or more. It is expected that communication needs between different models will increase.
[0003]
On the other hand, the image processing devices used for the various devices as described above employ an image format that is optimal for each device, and the image processing devices provided for each device also have various image processing functions. For this reason, in the conventional image processing apparatus, the image format requested by the receiving side is once converted via the PC, or the devices on the transmitting side and the receiving side are specified in advance. The data is transmitted in a predetermined specific image format, and the receiving side performs necessary conversion. However, in such a method, when the data is transmitted through a PC, the data has to be once transferred to the PC, so that the convenience is reduced. Further, when the devices on the transmission side and the reception side of the image data are specified, However, image data can be transmitted and received only between specific devices.

First, the operation is the same as that of a conventional general system to which the present invention is not applied, and differs from the present invention. The operation of a conventional general system for comparison will be described.
[0033]
Prior to photographing, the user operates an operation unit (not shown) such as a key and a dial to selectively determine a photographing mode from, for example, a high image quality mode, a low image quality mode, and a document photographing mode. Such operation contents of the user are determined by the system control unit 2 through the operation interface unit 9. The system control unit 2 generates guidance graphics for guidance display via the display control unit 5 according to the content of the operation, displays the guidance graphics on the LCD 6, and prompts the user for the next operation. When the shooting mode is determined, the system control unit 2 sets processing parameters corresponding to the shooting mode in the image processing unit 4.
After preparation for shooting is completed, when a half-pressed state of a release button (included in the operation unit) (not shown) is detected, the operation is performed in the same manner as in the previous mode setting. The determination is made by the system control unit 2 via the unit 9.
Under the control of the image processing unit 4, the imaging unit 3 starts an imaging operation for displaying a preview image prior to actual shooting. The captured data is sent to the image processing unit 4 continuously. After performing processing such as color space conversion, gamma correction, and white balance adjustment on the image data, the image processing unit 4 sends the image data to the display control unit 5. At this time, the image processing unit 4 simultaneously detects the focus and the exposure, and controls the imaging unit 3 accordingly to perform adjustment.
[0034]
The display control unit 5 performs necessary signal processing on the sent image data, displays the processed image data on the LCD 6, and presents the user with an imaging state.

Here, the header information includes information on the selected shooting mode, information on the shooting date and time, and the like.
[0035]
Thus, a series of photographing operations is completed.
Next, the operation of image transmission by the communication function will be described.
The user connects the mobile phone 11 to the digital still camera 1 through the communication interface unit 10 before using the communication function. As in the case of the setting of the shooting mode described above, the user specifies the transmission destination of the image and selects the image to be transmitted.
In a conventional general system, a system control unit 2 controls a communication interface unit 10 to make a call using a mobile phone 11 and, when a communication path is established, first receives a terminal name of a partner terminal, A terminal attribute table stored in the control unit 2 is searched in advance to determine a transmission image format.
Table 1 shows an example of the terminal attribute table. In Table 1, the terminal name indicates the type of the transmission partner terminal, and the terminal attribute indicates the image size, color space, and gradation that each transmission partner terminal can transmit (that is, can be received and used by the partner terminal). It shows numbers, compression formats, image formats, and the like.
[0036]
[Table 1]
Terminal attribute table
[0037]
After determining the transmission image format, the system control unit 2 reads out the specified image file from the recording medium 6, transfers the image file to the image processing unit 4 as necessary, performs image processing such as scaling, and then performs further image processing. And converts the image data according to a predetermined protocol.
If the terminal attribute cannot be determined, such as a terminal name that does not exist in the table of Table 1, processing is interrupted as a transmission impossible error, and a guidance message indicating that fact is displayed on the LCD 6.
Next, the operation of image transmission when the present invention is applied will be described.
First, a communication flow (corresponding to claims 1, 2 and 14) in the system according to the present invention will be described. 2 to 5 show communication procedure diagrams schematically showing the flow of signal transmission and reception in communication. 2 is a communication flow at the time of connection, FIG. 5 is a communication flow at the time of disconnection, and FIG. 3 is a connection when the transmitting side determines image processing contents, that is, when the transmitting side is a master (FIG. 2). FIG. 4 shows a communication flow between the connection (FIG. 5) and disconnection (FIG. 5), and FIG. 4 shows a communication flow between the connection (FIG. 2) and disconnection (FIG. 5) when the receiving side is the master.
[0038]
In FIG. 2, a normal call connection procedure via a network is performed from the calling to the connection confirmation of the calling terminal (transmitting side) and the connection response of the called terminal (receiving side).
When the call is connected, first, the receiving side notifies the transmitting side of the version number of the algorithm that determines the processing content of the image (provided by the terminal itself). The transmitting side compares the notified version number with a similar version number in its own terminal.If the version number of its own terminal is the same or newer, its own terminal becomes the master terminal. Side is determined as the master terminal.
FIG. 5 shows a normal call disconnection procedure via a network.
FIG. 3 shows a processing procedure when the transmitting side is determined to be the master terminal in the procedure of FIG. 2 as described above. Upon receiving the notification that the transmitting side is the master terminal, the receiving side notifies information about the image format of the own terminal and the image processing function of the own terminal. Here, as the image format, a plurality of formats requested by the receiving side can be notified.
[0039]
The transmitting side determines image processing contents to be performed on the transmitting side based on the notified information and information on the source image format and the image processing function of the terminal itself, and notifies processing contents to be performed on the receiving side. Here, if the processing content cannot be determined, in other words, even if it has the image processing function provided on both the transmitting side and the receiving side, it is necessary to convert the image into any of the image formats used on the receiving side. If it is determined that the transmission is not possible, the transmission is notified and the process proceeds to the disconnection process (FIG. 5). The method for determining the processing will be described later.
The transmitting side processes the transmission source image according to the determined processing content and sequentially transmits the images. Transmission of image data is performed by transmitting a predetermined data amount in packet units. When the transmission of the image data is completed, the receiving side processes the received image according to the previously notified processing contents, records the image on the recording medium, and disconnects the connection according to the procedure shown in FIG.
[0040]
FIG. 4 shows a procedure of processing when the receiving side is the master terminal in the procedure of FIG. 2 described above.
When the transmitting side notifies that the receiving side is the master terminal, the transmitting side notifies information about the source image format and the image processing function of the terminal.
The receiving side determines the content of the image processing to be performed on the transmitting side based on the notified information, the image format of the own terminal, and the information on the image processing function of the own terminal, and notifies the determined content. Here, when the processing content cannot be determined, the reception impossibility is notified, and the procedure shifts to the disconnection procedure shown in FIG. Note that, as described above, the method of determining the processing will be described later.
The transmission side processes the transmission source image according to the notified processing content and sequentially transmits the images. Transmission of image data is performed by transmitting a predetermined data amount in packet units.
When the data transmission is completed, the receiving side processes the received image according to the processing content determined previously, records the image on the recording medium, and disconnects the connection according to the procedure shown in FIG.
Next, some examples of the above-described method of determining the processing content will be described.

Hereinafter, a method for determining the processing content will be specifically described.
Table 3 shows the source image format. Tables 4 and 5 show the first and second receiving-side image formats. As described above, a plurality of formats can be designated as the receiving-side image format. In this example, one of the formats shown in Table 4 or Table 5 is requested.

[0049]
FIG. 6 shows the flow of processing related to the determination of the processing content.
Hereinafter, description will be given according to the flowchart shown in FIG.
First, the master terminal receives the image processing function information of the partner terminal according to the communication procedure described above, and receives a receivable image format (when the transmission side is master) or a transmission image format (when the reception side is master) ( Steps S1 and S2). Then, the master terminal determines which of the quality and the processing speed is prioritized (when the receiving side is the master), or receives the priority from the partner terminal (when the transmitting side is the master) (step S3) (step S3). A method that prioritizes processing quality corresponds to claim 10, and a method that prioritizes processing speed corresponds to claim 11.)
[0050]
The above-mentioned priorities can be set by the user or automatically determined depending on how the terminal uses the image information (the priorities are determined in this manner, and processing is performed based on the priorities. The method of determining the contents corresponds to claim 13.) This priority specification can be performed by both the transmitting terminal and the receiving terminal regardless of whether the master terminal is the transmitting terminal or the receiving terminal. There are the following four combinations in this case.
1) The transmitting side follows the specification received from the receiving side at the time of master.
2) When the transmitting side is a master, it follows the determination on the transmitting side.
3) The receiving side follows the specification received from the transmitting side at the time of master.
4) When the receiving side is the master, it follows the determination on the receiving side.
[0051]
When the priority is specified in both the transmitting terminal and the receiving terminal, the determination of the transmitting terminal is followed.
When the master terminal (system control unit 2) is notified of the above-mentioned information, the master terminal (based on the combination of the image processing function of the partner terminal and the image processing function of the own terminal) receives the information, and receives the image format of the transmission source. Then, all the combinations of processes that can be converted into are extracted, and a table for determining the process contents is created (step S4).
Table 8 shows a processing determination table. In Table 8, the numbers indicate the serial numbers assigned for explanation, and the transmission side processing / reception side processing indicates the extraction result of the combination of the above-described processing. Other items will be described later.
[0052]
[Table 8]
Processing judgment table
[0053]
If there is no processable combination, a transmission disable notification (at the time of the master on the transmission side) / a reception disable notification (at the time of the master on the reception side) is transmitted to the partner terminal, and the process is terminated (steps S5 to S6). .
If there is only one combination that can be processed, the processing is determined as the processing content (step S7).
If there are two or more combinations that can be processed, (the system control unit 2 of) the master terminal calculates the processing time. The processing time indicates the processing performance of the image processing function of the partner terminal and the image processing function of the own terminal (Tables 6 and 7) and the processing performance of each of the combinations that can be processed (numbers 1 to 5 in Table 8). It is calculated from the image size processed in the processing (step S8).
For example, in the process for No. 1 in Table 8, individual processing times are as shown in Expressions 1 to 8.
[0054]
JPEG2000 decompression processing
2048 × 1536 × 300E-6 = 944 (ms) (Equation 1)
1/2 reduction processing
2048 × 1536 × 12000E-6 = 37749 (ms) (Expression 2)
JPEG compression processing
1024 × 768 × 200E-6 = 157 (ms) (Equation 3)
JPEG decompression processing
1024 × 768 × 25000E-6 = 19661 (ms) (Equation 4)
5/8 reduction processing
1024 × 768 × 600E-6 = 472 (ms) (Equation 5)
YUV422 → YUV420 processing
640 × 480 × 720E-6 = 222 (ms) (Equation 6)
JPEG compression processing
640 × 480 × 25000E-6 = 7680 (ms) (Equation 7)
JFIF file creation processing
2 (ms) (Equation 8)
The processing time 66.9 (s) is calculated by adding all of the results of Equations 1 to 8.
[0055]
Subsequently, (the system control unit 2 of) the master terminal calculates the processing quality index. The processing quality index is calculated from the processing quality indices of the image processing function of the partner terminal and the image processing function of the own terminal (Tables 6 and 7) for all combinations that can be processed (Nos. 1 to 5 in Table 8). It is calculated (step S9).
For example, in the process for No. 1 in Table 8, the processing quality index is calculated as in the following Expression 9.
(100 (JPEG2000 extension processing) / 100
× 90 (1 / reduction processing) / 100
× 90 (JPEG compression processing) / 100
× 100 (JPEG expansion processing) / 100
× 75 (5/8 reduction processing) / 100
× 85 (YUV422 → YUV420 treatment) / 100
× 90 (JPEG compression processing) / 100
× 100 (JFIF file creation processing) / 100)
× 100
= 46.5 (Equation 9)
[0056]
Subsequently, (the system control unit 2 of) the master terminal calculates a predicted transmission time. In calculating the predicted transmission time, the data amount is calculated from the transmission data format for all the combinations that can be processed (Nos. 1 to 5 in Table 8), and the predicted transmission time is calculated from the transmission rate of the transmission medium ( Step S10) (In this case, when the estimated transmission time is reflected in the determination of the processing content, it corresponds to claim 12).
For example, in the process for No. 1 in Table 8, the estimated transmission time is calculated as follows.
The transmission data format is JPEG data, and the JPEG compression rate is 1 / 7.7 (this value is stored in the system control unit 2 in advance as a standard compression rate for JPEG compression). Equation 10
[0057]
1024 × 768 × 2 × 1 / 7.7 = 200 (KB) (Equation 10)
Assuming that the transmission rate is 128 kbps (this value is a value notified via the communication interface unit 10 at the time of call connection as the transmission capacity of the connected network), the transmission expected time is calculated by Expression 11.
200 × 1024 × 8 / (128 × 1000) = 12.8 (s) (Equation 11) When the calculation is completed (each item in Table 8 is filled) as described above, the system control unit of the master terminal ( In 2), the processing content is determined. In deciding, the optimum one is selected from Table 8 according to the above-mentioned priority of quality / processing speed. For example, if priority is given to quality, the process of number 2 having the highest quality index in Table 8 is selected. Alternatively, if priority is given to the processing speed, the processing of number 1 having the shortest “processing + transmission time” in Table 8 is selected (step S11).
[0058]
The master terminal transmits the determined processing content and a notification that transmission is possible to the partner terminal (step S12), performs image processing according to the determined processing content (step S13), and transmits image data (step S13). S14).
In the above description, in at least one of the image processing apparatuses on the transmission side and the reception side, the processing content of the image information is selected. However, the configuration for selecting the processing content is the transmission side and the reception side.
