Description

  The present invention relates to an information processing apparatus, a communication method thereof, and a computer-executable program.

  Recently, in personal computers (hereinafter referred to as “PC”), VoIP (Voice over Internet Protocol) such as Skype (registered trademark) has been developed as the camera mounting rate increases and the speed and capacity of communication lines increase. Chats and video conferences are held between two locations using an application program.

  In such a VoIP application program, a PC user is photographed by a camera, and the photographed image is transmitted to the partner PC. The captured image is displayed on the monitor of the other party's PC. There are various types of monitors such as an LCD, an organic EL display, a plasma display, a projector, and a CRT.

  FIG. 10 is a diagram illustrating a display example of the monitors 102 and 103 of the notebook PCs 100 and 200 when the PC 100 and the PC 200 are communicating via a videophone. VoIP application programs such as Skype are installed in the PC 100 and the PC 200. As shown in FIG. 10, the VoIP application program is activated on the PC 100 and the PC 200, and the windows WA1 and WB1 are displayed on the screens 102 and 202, respectively. Mr. A is the owner of the PC 100, and the image of Mr. A taken by the camera 101 is transmitted to the PC 200 of Mr. B and displayed in the window WB1. On the other hand, Mr. B is the owner of the PC 200, and the image of Mr. B taken by the camera 201 is transmitted to the PC 100 of Mr. A and displayed on the window WA1.

  For example, when the gradation characteristic of the monitor 202 of Mr. B's PC 200 is low or the color reproduction range is narrow, when the image of Mr. A taken by the camera 101 of Mr. A's PC 100 is sent as it is, the image of Mr. B's PC 200 is transmitted. The image of Mr. A displayed on the monitor 202 may not be able to display a high-quality image with low gradation and saturation. In general, since a projector has a low gradation and a narrow color reproduction range, when a monitor of the counterpart terminal is a projector, if the captured image is sent to the counterpart terminal as it is, the monitor of the counterpart terminal will display the image quality. A low-quality image may be displayed.

(Embodiment)
FIG. 1 is a diagram illustrating a functional configuration example of a video conference system to which the information processing apparatus according to the present embodiment is applied. The information processing apparatuses 1 </ b> A and 1 </ b> B are configured to be able to communicate with each other via the network 7. The information processing apparatuses 1A and 1B are, for example, notebook PCs or desktop PCs, and are equipped with a video conference application program such as a VoIP application program, and a video conference is possible between them.

  The information processing apparatuses 1A and 1B include cameras 2A and 2B that capture an image of a subject, monitors 3A and 3B that display images, and a parameter acquisition unit 4A that acquires parameters 3B1 and 3A1 related to the monitors 3B and 3A of the counterpart terminal from the counterpart terminal. 4B and based on the acquired parameters 3B1 and 3A1, correction (adjustment) units 5A and 5B for correcting (adjusting) the image quality of images captured by the cameras 2A and 2B, and images corrected by the correction units 5A and 5B Correction image transmission units 6A and 6B that transmit to the counterpart terminal are provided. Here, the monitors 3A and 3B are, for example, an LCD, an organic EL display, a plasma display, a projector, a CRT, or the like.

  As described above, when an image captured by a camera is sent to a partner terminal as it is and displayed on the monitor of the partner terminal, the image quality may be lowered depending on the type of the monitor. Therefore, in the present embodiment, the image captured by the camera is corrected in accordance with the monitor characteristics of the counterpart terminal, the corrected image is sent to the counterpart terminal, and high-quality image display can be performed on the monitor of the counterpart terminal. I am doing so.

  In the information processing apparatus 1A, the parameter acquisition unit 4A acquires the parameter 3B1 related to the monitor 3B from the information processing apparatus 1B. The parameters relating to the monitor include, for example, EDID (Extended Display Identification Data), an ICC profile, or an image quality parameter currently set in the monitor (luminance and color that can be dynamically adjusted by the information processing apparatus). , And gradation gamma, etc.).

  The correction unit 5A corrects the image quality of the image captured by the camera 2A based on the parameter 3B1 of the monitor 3B acquired by the parameter acquisition unit 5A. For example, when the parameter 3B1 includes the color reproduction range and the color reproduction range is low, correction may be performed to increase the saturation of the image captured by the camera 2A. Also, for example, when the parameter 3B1 includes gradation gamma (gradation characteristics) and the gradation gamma is low, correction is performed to increase the gradation of the image captured by the camera 2A. Also good.

  The corrected image transmission unit 6A transmits the image corrected by the correction unit 5A to the information processing apparatus 1B and displays it on the monitor 3B. In the information processing apparatus 1A, when an image captured by the camera 2A is displayed on the monitor 3A, an image that has not been corrected by the correction unit 5A may be displayed.

  If the parameter acquisition unit 4A cannot acquire the parameters related to the monitor from the counterpart terminal, the correction unit 5A performs correction to increase at least one of the saturation and the gradation gamma of the image captured by the camera 2A. It may be. In this case, since the monitor of the counterpart terminal does not hold the parameters relating to the monitor, it is considered to be an old type monitor, and it is considered that the color reproduction range is narrow or the gradation gamma is low.

  Also, the information processing apparatus 1A sends the parameter 3A1 related to the monitor 3A to the parameter acquisition unit 4B of the information processing apparatus 1B in response to a request from the parameter acquisition unit 4B of the information processing apparatus 1B. In the information processing apparatus 1B, the correction unit 5B corrects the image quality of the image captured by the camera 2B based on the parameter 3A1 of the monitor 3A acquired by the parameter acquisition unit 5B. The corrected image transmission unit 6B transmits the image corrected by the correction unit 5B to the information processing apparatus 1A. In the information processing apparatus 1A, the corrected image is received and displayed on the monitor 3A.

  As described above, according to the present embodiment, the information processing apparatus 1A includes the parameter acquisition unit 4A that acquires the parameter 3B1 related to the monitor 3B of the counterpart terminal from the counterpart terminal (information processing apparatus 1B), and the acquired parameter. Based on 3B1, a correction unit 5A that corrects the image quality of an image captured by the camera 2A and a corrected image transmission unit 6A that transmits an image whose image quality has been corrected by the correction unit 5A to the counterpart terminal are provided. When the image captured at 2A is transmitted to the counterpart terminal and displayed on the monitor 3B of the counterpart terminal, a high-quality image can be displayed.

  Further, according to the present embodiment, the monitor-related parameter includes the color reproduction range, and the correction unit 5A performs correction to increase the saturation of the image captured by the camera 2A when the parameter color reproduction range is narrow. Since this is done, an image with high saturation can be displayed even when the monitor of the counterpart terminal has low saturation.

  Further, according to the present embodiment, the monitor-related parameter includes the gradation gamma, and the correction unit 5A corrects the gradation gamma of the image captured by the camera 2A when the parameter gradation gamma is low. Thus, even when the gradation gamma of the monitor of the counterpart terminal is low, an image with a high gradation gamma can be displayed.

  Further, according to the present embodiment, the monitor-related parameters are, for example, EDID, ICC profile, or image quality parameters currently set for the monitor, and therefore various parameters related to the monitor are used. It becomes possible.

  In addition, according to the present embodiment, when the parameter acquisition unit 5A cannot acquire the parameters related to the monitor of the counterpart terminal, the correction unit 5A has at least saturation and gradation gamma of the image captured by the camera 2A. Since the correction to increase one is performed, if the counterpart terminal does not hold the monitor parameters, there is a high possibility that the monitor is an old type monitor, and there is a possibility that the monitor is low in saturation or gradation. Therefore, even an old type monitor can display an image with high saturation or gradation.

  In addition, according to the present embodiment, when displaying an image captured by the camera 2A on the monitor 3A of the information processing apparatus 1A, an image not corrected by the correction unit 5A is displayed. It is possible to display an image suitable for the monitor.

On the other hand, in the notebook PC 10B, the image of Mr. B taken by the camera 18B is corrected based on the EDID of the monitor 17 of the notebook PC 10, and the corrected image is transmitted to the notebook PC 10 and displayed on the window WA1 of the monitor 17. The

  Next, a method for correcting an image captured by the camera 18 will be described in detail. As described in “SEP 2006-9 Enhanced Extended Display Identification Data Standard (E-EDID) Rel. A, 2.0”, EDID defines parameters unique to a monitor device. The data format of EDID is that the header address 00h is the header, the vendor and product information is address 08h to 11h, the version information of the EDID structure is address 12h and 13h, the horizontal size and vertical size of the effective display area are addresses 14h to 18h, Basic information of the monitor device such as gradation gamma (address 17h), addresses 19h to 22h, color information, addresses 23h to 25h, vertical sync frequency and horizontal sync frequency ranges, the number of displayable pixels, Timing information peculiar to the monitor device, addresses 26h to 34h, standard pixel number support information, addresses 36h to 6Ch, detailed information, address 7Eh, an extension flag, and address 7Fh, a checksum are stored. Yes.

  The VoIP application program 42 acquires the EDID of the monitor 17B of the counterpart terminal 10B from the counterpart terminal 10B, and based on the acquired EDID tone gamma (address 17h) and color reproduction range (addresses 14h to 18h) The camera driver 41a is instructed to set the gamma value and saturation parameters. In response to this instruction, the camera driver 41a sets the gradation gamma and saturation parameters in the signal processing circuit 26. The signal processing circuit 26 corrects the image quality of the image captured by the camera 18 in accordance with the set parameters (gradation gamma and color). The VoIP application program 42 transmits the image corrected by the signal processing circuit 26 to the counterpart terminal 10B via the communication device 29.

  FIG. 6 is a diagram for explaining an example of correcting the saturation of an image, and shows an xy chromaticity diagram (NTSC color reproduction range (color space). The VoIP application program 42 is connected to the counterpart terminal. The color reproduction range (Rx, Ry, Gx, Gy, Bx, By) is acquired from the addresses 14h to 18h of the EDID When the color reproduction range is narrow, for example, when it is smaller than 72% of the NTSC ratio The camera driver 41a is instructed to set a parameter for increasing the saturation, and the camera driver 41a sets a parameter for increasing the saturation in the signal processing circuit 26 in response to the instruction. The signal processing circuit 26 performs image processing for increasing the saturation of the image captured by the camera 18. In FIG. When the color reproduction range of the monitor of the counterpart terminal is “a” and the image data picked up by the camera 18 is sent as it is, an image with low saturation in the range as shown in “b” is displayed, but the saturation is increased. By transmitting the processed image, an image with high saturation in a range such as c is displayed.

  FIG. 7 is a diagram for explaining an example of correcting the gradation gamma γ of an image. The VoIP application program 42 acquires the gradation gamma from the EDID address 17h. The VoIP application program 42 instructs the camera driver 41a to set a parameter for increasing the gradation gamma γ when the gradation gamma γ is low, for example, lower than γ = 2.2. In response to the instruction, the camera driver 41a sets a parameter for increasing the gradation gamma γ in the signal processing circuit 26. The signal processing circuit 26 performs image processing for increasing the gradation gamma γ of the image captured by the camera 18. In FIG. 7, for example, when the gradation gamma γ is d in the figure (γ = 1.0), the gradation gamma is increased as in e (γ = 2.2). As a result, an image with high gradation gamma is displayed on the monitor of the counterpart terminal.

  FIG. 8 is a flowchart for explaining the outline of the processing operation of the VoIP application program 42. First, the VoIP application program 42 performs a connection / association process with a partner terminal to be called (step S1). Next, the VoIP application program 42 acquires the EDID of the monitor from the counterpart terminal (step S2). The VoIP application program 42 sets gradation gamma and saturation parameters in the signal processing circuit 26 via the camera driver 41a based on the obtained gradation gamma and color reproduction range of EDID (step S3). The signal processing circuit 26 corrects the image captured by the camera 18 in accordance with the set parameters (gradation gamma and saturation) (step S4). The VoIP application program 42 transmits the corrected image to the counterpart terminal via the communication device 29 (step S5).

  When the other terminal does not hold (support) the monitor's EDID, it is considered an old type monitor, and it is considered that the monitor has a low gradation gamma or a narrow color reproduction range. An image in which at least one of gradation gamma and saturation of the image is increased may be transmitted to the counterpart terminal. In addition, when the counterpart terminal has a plurality of monitors, the EDID of the primary monitor may be acquired and the captured image may be corrected based on the EDID.

  FIG. 9 is a diagram for explaining a modification. Description of the parts common to FIG. 5 is omitted. The VoIP application program 42 may display both an image sent from the counterpart terminal and an image taken by the camera 18 of the own device. In FIG. 9, images captured by the cameras 18 and 18B of the own apparatus are displayed in windows WA2 and WB2, respectively. In this case, it is desirable to display an uncorrected image instead of an image corrected based on the EDID of the monitor of the counterpart terminal in the windows WA2 and WB2. This is because if an image corrected in accordance with the characteristics of the other party's monitor is displayed, an image suitable for the monitor characteristics of the own apparatus may not be displayed.

  In the above embodiment, the case where the present invention is applied to a notebook PC has been described. However, the present invention is not limited to this, and can be applied to other information processing apparatuses such as a desktop PC, a PDA, and a mobile phone. It is.

  The information processing apparatus, its communication method, and computer-executable program of the present invention can be widely used in video conferences, chats, and the like.
