## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims priority from Japanese Patent Application No. 2010-221550 filed in the Japan Patent Office on Sep. 30, 2010 and Japanese Patent Application No. 2010-289780 filed in the Japan Patent Office on Dec. 27, 2010, the entire contents of which are hereby incorporated by reference.
BACKGROUND
The present disclosure relates to an information processing apparatus and an information processing method.
In general, as devices used for communication between users being in different locations, telephones, so-called videophones, and video conference systems have been used. In addition, text chat and video chat including video images and audio have also been performed through the Internet using personal computers.
Therefore, electronic devices and like devices have been offering high functionalities and an increasing range of functions. For example, a television receiver includes a network communication function which enables not only reception of video and audio content of a program from a broadcasting station and display of the content but also transmission of various information to and reception of various information from another receiver.
For example, Japanese Unexamined Patent Application Publication No. 2006-50370 discloses a technique of displaying, when a user views program content of television broadcasting using a television receiver, information on registered other users (such as thumbnail images of the other users, and names, channels, and video images of content viewed by the other users) together with the program content.
Here, when display of content and display of an image externally received through network communication (hereinafter referred to as a “communication image”) are performed in parallel in a display device such as a television receiver, a PIP (Picture in Picture) display method or a POP (Picture on Picture) display method is generally used.
However, there arises a problem in that, when the PIP display method or the POP display method is used, a portion of the displayed content is hidden by the displayed communication image, and accordingly, it is difficult to view the content. Furthermore, in general, since a region for displaying the communication image is limited in a display screen, a size of the communication image is reduced in the display screen. Therefore, there arises a problem in that sizes of images of other users included in the communication image become small, and accordingly, it is difficult to identify the users and image quality of the communication image is deteriorated.
Accordingly, it is desirable to provide an improved information processing apparatus and an improved information processing method which have novelty and which are capable of appropriately performing display of content and display of a communication image when the content and the communication image are displayed in parallel.
SUMMARY
In accordance with one aspect of the embodiments, an information processing apparatus may include an obtaining unit to obtain a number of users from information on detection of a face region including a face in a captured image provided at the apparatus. The apparatus also may include a setting unit to set a display region for content and a display region for a captured image in a display screen. Further, the apparatus may include a display image generation unit to generate a display image to be displayed in the display region for a captured image, in accordance with the information on the detection, the number of users, and the display region set for a captured image.
In accordance with another aspect of the embodiments, a method may include obtaining a number of users from information on detection of a face region including a face in a captured image; setting a display region for content and a display region for a captured image in a display screen; and generating a display image to be displayed in the display region for a captured image, in accordance with the information on the detection, the number of users, and the display region set for a captured image. In such method, at least one of the obtaining, the setting and the generating may be by a processor.
In accordance with another aspect of the embodiments, a non-transitory recording medium may be recorded with a computer-readable program having instructions executable by a processor. The program may include obtaining a number of users from information on detection of a face region including a face in a captured image; setting a display region for content and a display region for a captured image in a display screen; and generating a display image to be displayed in the display region for a captured image, in accordance with the information on the detection, the number of users, and the display region set for a captured image.
As described above, display of content and display of a communication image may be appropriately performed in parallel.

Next, a functional configuration of an information processing apparatus according to a first embodiment of the present disclosure will be described. FIG. 2 is a diagram illustrating a functional configuration of the information processing apparatus according to the first embodiment of the present disclosure. Note that, FIG. 2 includes a display system 100 which transmits a captured image to an information processing apparatus 200 serving as the information processing apparatus according to this embodiment and which receives a signal for driving the display device 102 from the information processing apparatus 200 and a user A who uses the display system 100 and the information processing apparatus 200. Furthermore, FIG. 2 includes a communication network 800 to which the information processing apparatus 200 is connectable, a communication server 300 and other information processing apparatuses 500 and 700 which are connectable to the communication network 800, a display system 400 which transmits a captured image to the information processing apparatus 500 and which receives a signal from the information processing apparatus 500, users B and C who use the display system 400 and the information processing apparatus 500, a display system 600 which transmits a captured image to the information processing apparatus 700 and which receives a signal from the information processing apparatus 700, and a user D who uses the display system 600 and the information processing apparatus 700. The display systems 400 and 600 have the same configurations as the display system 100, and therefore, detailed descriptions thereof are omitted. Furthermore, the information processing apparatuses 500 and 700 have the same configurations as the information processing apparatus 200, and therefore, detailed descriptions thereof are omitted. The information processing apparatuses 500 and 700 are examples of communication object apparatuses according to the present disclosure.
In FIG. 2, the information processing apparatus 200 includes an input unit 202, a detection unit 204, a head-count obtaining unit 206, a setting unit 208, a display image generation unit 210, a communication unit 212, an output unit 214, and a display controller 216.
The input unit 202 receives a captured image which is generated by the image pickup device 104 through image capturing. The captured image generated by the image pickup device 104 through the image capturing is an example of another captured image according to the present disclosure. Then, the input unit 202 transmits the received (input) captured image to the communication unit 212. Note that the input unit 202 may transmit the received captured image to the detection unit 204 and the display image generation unit 210. Furthermore, the input unit 202 accepts an input for a setting of a display ratio of a display region for content to a display region for captured images supplied from the information processing apparatuses 500 and 700 in a display screen of the display device 102 performed by the user A, for example. Note that the input unit 202 may accept an input for a setting of a display ratio of a display region for content to a display region for captured images supplied from the information processing apparatus 200, 500, and 700 in the display screen of the display device 102 performed by the user A. Then, the input unit 202 transmits information on the received input for a setting of a display ratio to the setting unit 208. The display region for captured images supplied from the information processing apparatuses 200, 500, and 700 is an example of a second display region according to the present disclosure.
The detection unit 204 which is an example of a detection unit according to the present disclosure receives captured images which are supplied from the information processing apparatuses 500 and 700 and which are received by the communication unit 212 and detects face regions including faces of the users B, C, and D in the received captured images. Then, the detection unit 204 transmits information on the face regions as results of the detection to the head-count obtaining unit 206 and the display image generation unit 210. Note that the detection unit 204 may receive a captured image supplied from the input unit 202 and detect a face region including a face of the user A in the received captured image. Then, the detection unit 204 may transmit information on the face region including the face of the user A as a result of the detection to the head-count obtaining unit 206, the display image generation unit 210, and the communication unit 212. A technique disclosed in Japanese Unexamined Patent Application Publication No. 2007-65766 and a technique disclosed in Japanese Unexamined Patent Application Publication No. 2005-44330 may be used for the detection of a face region performed on a captured image by the detection unit 204. Hereinafter, the detection of a face region will be briefly described.
To detect the face of the user A in the captured image, for example, a face position, a face size, and a face direction are individually detected in the received captured image. When the face position and the face size are detected, a portion corresponding to a face image may be extracted from the image. Then, in accordance with the extracted face image and information on the face direction, characteristic portions of the face (face feature positions) such as eye blows, eyes, a nose, and a mouth are detected. A method referred to as an AAM (Active Appearance Models) method, for example, may be used for the detection of the face feature positions.
After the face feature positions are detected, local feature values of the detected face feature positions are individually calculated. When the local feature values are calculated and the calculated local feature values are stored along with the face image, a face is identified in the image captured by the image pickup device 104. A technique disclosed in Japanese Unexamined Patent Application Publication No. 2007-65766 or a technique disclosed in Japanese Unexamined Patent Application Publication No. 2005-44330 may be used as a method for identifying a face, and therefore, a detailed description thereof is omitted here. Furthermore, in accordance with the face image and the face feature positions, a gender and an age of a face included in the received captured image may be determined. Moreover, by storing information on faces in advance, the face of the user included in the received captured image may be obtained from among the stored faces so as to specify the user.
The head-count obtaining unit 206 which is an example of an obtaining unit according to the present disclosure receives information on the face regions including the faces of the users B, C, and D detected by the detection unit 204. Then, the head-count obtaining unit 206 obtains the number of users who use the information processing apparatuses 500 and 700 in accordance with the received information on the face regions. Thereafter, the head-count obtaining unit 206 transmits a result of the obtainment of the number of users who use the information processing apparatuses 500 and 700 to the display image generation unit 210. Note that the head-count obtaining unit 206 may receive information on a face region including the face of the user A detected by the detection unit 204 and obtain the number of users who use the information processing apparatus 200 in accordance with received information on the face region including the face of the user A. Then, the head-count obtaining unit 206 may transmit a result of the obtainment of the number of users who use the information processing apparatus 200 to the display image generation unit 210 and the display controller 216. Furthermore, when the communication unit 212 receives the information on the face regions including the faces of the users B and C detected in the image captured using the display system 400 and information on the face region including the face of the user D detected in the image captured using the display system 600, the head-count obtaining unit 206 may receive the information on the face regions and obtain the number of users who use the information processing apparatuses 500 and 700 in accordance with the received information on the face regions. In this case, the detection unit 204 described above may not detect the face regions including the faces of the users B, C and D in the captured images supplied from the information processing apparatuses 500 and 700.
The setting unit 208 which is an example of a setting unit according to the present disclosure receives information on the input for the setting of the display ratio from the input unit 202 and sets the display region for content and a display region for captured images supplied from the information processing apparatuses 500 and 700 in the display screen of the display device 102 in accordance with the received information on the input for the setting of the display ratio. Furthermore, the setting unit 208 may set a display region for content and a display region for captured images supplied from the information processing apparatuses 200, 500, and 700 in the display screen of the display device 102 in accordance with the received information on the input for the setting of the display ratio. Then, the setting unit 208 transmits information on the set display region for captured images to the display image generation unit 210 and the display controller 216 and transmits information on the set display region for content to the display controller 216. For example, the setting unit 208 sets a size of the display region for content and a size of the display region for captured images supplied from the information processing apparatuses 500 and 700 in the display screen of the display device 102 and transmits information on the set size of the display region for content and information on the set size of the display region for captured images.
The display image generation unit 210 which is an example of a generation unit according to the present disclosure receives information on the face regions including the faces of the users B, C, and D from the detection unit 204, receives the result of the obtainment of the number of users who use the information processing apparatuses 500 and 700 from the head-count obtaining unit 206, receives the information on the display region for captured images supplied from the information processing apparatuses 500 and 700 from the setting unit 208, and receives the image captured using the display system 400 and the image captured using the display system 600 which are received by the communication unit 212. Then, in accordance with the received information on the face regions including the faces of the users B, and C and D, the received result of the obtainment of the number of users who use the information processing apparatuses 500 and 700, and the information on the display region for captured images supplied from the information processing apparatuses 500 and 700, the display image generation unit 210 generates a display image to be displayed in the display region for captured images supplied from the information processing apparatuses 500 and 700 included in the display screen of the display device 102 using the image captured by the display system 400 and the image captured by the display system 600. Thereafter, the display image generation unit 210 transmits the generated display image to the display controller 216.
For example, the display image generation unit 210 extracts a portion of the image captured by the display system 400 corresponding to one third of the display region for captured images such that at least face feature portions of the user B are included in the portion in accordance with the information on the face region including the face of the user B, the result of the obtainment of the number of users who use the information processing apparatuses 500 and 700, that is, information representing that the number of users is three, and the information on the display region for captured images supplied from the information processing apparatuses 500 and 700 such as information on the size of the display region.

The ROM 232 stores programs and control data such as calculation parameters used by the MPU 230. The RAM 234 temporarily stores programs executed by the MPU 230, for example.
The recording medium 236 stores applications, for example. Here, examples of the recording medium 236 include a magnetic recording medium such as a hard disk and a nonvolatile memory such as an EEPROM (Electrically Erasable and Programmable Read Only Memory), a flash memory, an MRAM (Magnetoresistive Random Access Memory), an FeRAM (Ferroelectric Random Access Memory), or a PRAM (Phase change Random Access Memory). Furthermore, the information processing apparatus 200 may include a recording medium 236 which is detachable from the information processing apparatus 200.
The input/output interface 238 is connected to the operation input device 240 and the display device 242, for example. Furthermore, the input/output interface 238 functions as the input unit 202 and the output unit 214. The operation input device 240 functions as an operation unit (not shown), and the display device 242 functions as a display unit 254 which will be described with reference to FIG. 13. Here, examples of the input/output interface 238 include a USB (Universal Serial Bus) terminal, a DVI (Digital Visual Interface) terminal, an HDMI (High-Definition Multimedia Interface) terminal, and various processing circuits. Furthermore, the operation input device 240 is disposed on the information processing apparatus 200, for example, and is connected to the input/output interface 238 inside the information processing apparatus 200. Examples of the operation input device 240 include a button, a direction key, a rotatable selector such as a jog dial, and a combination thereof. Furthermore, the display device 242 is disposed on the information processing apparatus 200, for example, and is connected to the input/output interface 238 inside the information processing apparatus 200. Examples of the display device 242 include an LCD (Liquid Crystal Display) and an organic EL (ElectroLuminescence) display (which is also referred to as an OLED (Organic Light Emitting Diode) display). Note that it is apparent that the input/output interface 238 may be connected to an operation input device (for example, a keyboard and a mouse) serving as an external apparatus of the information processing apparatus 200 and an external device such as a display device (for example, an external display device such as the display device 102) and an image pickup device (for example, the image pickup device 104). Furthermore, the display device 242 may be a device which is capable of performing display and which allows a user's operation, such as a touch screen.
The communication interface 244 which is a communication unit included in the information processing apparatus 200 functions as the communication unit 212 which performs communication with an external apparatuses including the server 300 and the information processing apparatuses 500 and 700 through the network 800 (or directly) in a wireless/wired manner.

Moreover, the information processing apparatus 200 may not include the operation input device 240 and the display device 242 shown in FIG. 3, for example.
4. Display Process
Next, a display process executed by the information processing apparatus 200 shown in FIG. 2 will be described. FIG. 4 is a flowchart of the display process executed by the information processing apparatus 200 shown in FIG. 2.
In FIG. 4, first, when the user A inputs an instruction for displaying content desired by the user A in the display device 102 using the information processing apparatus 200, the display controller 216 transmits a signal for displaying the content desired by the user A in the display screen of the display device 102 to the output unit 214 which transmits the received signal to the display device 102. By this, the content desired by the user A is displayed in the display screen of the display device 102 (step S100).
Next, when the user A inputs an instruction for connection to the users B, C, and D through the network using the information processing apparatus 200, the communication unit 212 enters a state in which the communication unit 212 may communicate with the communication server 300 through the communication network 800 (in step S102). Note that, in step S102, the communication unit 212 may enter a state in which the communication unit 212 may directly communicate with the information processing apparatuses 500 and 700 through the communication network 800.
Next, the communication unit 212 transmits a captured image which is generated through image capturing performed by the image pickup device 104 included in the display system 100 and which is received through the input unit 202 to the communication server 300 through the communication network 800 (in step S104). Note that, in step S104, the communication unit 212 may transmit information on a face region including the face of the user A transmitted from the detection unit 204 to the communication server 300 through the communication network 800. Furthermore, in step S104, the communication unit 212 may directly transmit the captured image or the information on the face region to the information processing apparatuses 500 and 700 through the communication network 800.
Subsequently, the communication unit 212 receives an image which is captured by the display system 400 and which is transmitted from the information processing apparatus 500 through the communication server 300. Furthermore, the communication unit 212 receives an image which is captured by the display system 600 and which is transmitted from the information processing apparatus 700 through the communication server 300 (in step S106). Note that, in step S106, the information on the face regions including the faces of the users B and C detected in the image which is captured by the display system 400 and which is transmitted from the information processing apparatus 500 and the information on the face region including the face of the user D detected in the image which is captured by the display system 600 and which is transmitted from the information processing apparatus 700 may be received from the communication server 300. Furthermore, in step S106, the communication unit 212 may directly receive the captured images and the information on the face regions from the information processing apparatuses 500 and 700 through the communication network 800.
Subsequently, the information processing apparatus 200 executes a parallel display process which will be described with reference to FIG. 5 (in step S108) so that the content desired by the user A and the captured images supplied from the information processing apparatuses 500 and 700 are displayed in parallel in the display screen of the display device 102, and thereafter, the process is terminated.
FIG. 5 is a flowchart of the parallel display process performed in step S108 included in the display process shown in FIG. 4.
In FIG. 5, first, the head-count obtaining unit 206 obtains the number of users who use the information processing apparatuses 500 and 700 in accordance with the information on the face regions including the faces of the users B, C, and D detected by the detection unit 204 (in step S200). Note that, in step S200, the head-count obtaining unit 206 may obtain the number of users who use the information processing apparatus 200 in accordance with the information on the face region including the face of the user A detected by the detection unit 204. Furthermore, in step S200, when the communication unit 212 receives the information on the face regions including the faces of the users B and C detected in the image captured by the display system 400 and the information on the face region including the face of the user D detected in the image captured by the display system 600, the number of users who use the information processing apparatuses 500 and 700 may be obtained in accordance with the information on the face regions.
Next, the setting unit 208 sets a display region for content and a display region for captured images supplied from the information processing apparatuses 500 and 700 in the display screen of the display device 102 in accordance with information on an input performed by the user A to set the display ratio of the display region for content to the display region for captured images supplied from the information processing apparatuses 500 and 700 in the display screen of the display device 102 (in step S202). Note that, in step S202, the setting unit 208 may set the display region for content and the display region for captured images supplied from the information processing apparatuses 200, 500, and 700 in the display screen of the display device 102 in accordance with the information on an input performed by the user to set the display ratio of the display region for content to the display region for captured images supplied from the information processing apparatuses 200, 500, and 700 in the display screen of the display device 102.
Subsequently, the display image generation unit 210 extracts portions of the image which is captured by the display system 400 and which is received by the communication unit 212 and a portion of the image which is captured by the display system 600 and which is received by the communication unit 212 in accordance with the information on the face regions including the faces of the users B, C, and D transmitted from the detection unit 204, a result of the obtainment of the number of users who use the information processing apparatuses 500 and 700 which is supplied from the head-count obtaining unit 206, and the information on the display region for captured images supplied from the information processing apparatuses 500 and 700 which is supplied from the setting unit 208 (in step S204), and generates a display image to be displayed in the display region for captured images supplied from the information processing apparatuses 500 and 700 in the display screen of the display device 102 (in step S206).
Note that, in step S204 and step S206, the display image generation unit 210 may extract a portion of the image which is captured by the display system 100, portions of the image captured by the display system 400, and a portion of the image captured by the display system 600 in accordance with the information on the face region including the face of the user A transmitted from the detection unit 204, the information on the face regions including the faces of the users B, C, and D transmitted from the detection unit 204, a result of the obtainment of the number of users who use the information processing apparatus 200 which is supplied from the head-count obtaining unit 206, a result of the obtainment of the number of users who use the information processing apparatuses 500 and 700 which is supplied from the head-count obtaining unit 206, and the information on the display region for captured images supplied from the information processing apparatuses 200, 500, and 700 which is supplied from the setting unit 208, and generate a display image to be displayed in the display region for captured images supplied from the information processing apparatuses 200, 500, and 700 in the display screen of the display device 102.
Furthermore, in step S204 and step S206, when the communication unit 212 receives the information on the face regions including the faces of the users B and C detected in the image captured by the display system 400 and the information on the face region including the face of the user D detected by in the image captured by the display system 600, the display image generation unit 210 may generate a display image in accordance with the information on the face regions supplied from the communication unit 212 instead of the information on the face regions detected by the detection unit 204.
Next, the display controller 216 transmits a signal for displaying the content which is desired by the user A and which has a reduced size in the display region for content included in the display screen of the display device 102 to the output unit 214 in accordance with the information on the display region for content supplied from the setting unit 208. By this, the content desired by the user A which corresponds to the image having the reduced size is displayed in the display region for content in the display screen of the display device 102 (in step S208).
Next, the display controller 216 transmits a signal for displaying the display image generated by the display image generation unit 210 in the display region for captured images supplied from the information processing apparatuses 500 and 700 included in the display screen of the display device 102 to the output unit 214 in accordance with the information on the display region for the captured images supplied from the information processing apparatuses 500 and 700 which is received from the setting unit 208. By this, in the display screen of the display device 102, the display image generated by the display image generation unit 210 is displayed in the display region for captured images, and accordingly, the content desired by the user A and the captured images supplied from the information processing apparatuses 500 and 700 are displayed in parallel (in step S210). Then, this process is terminated.
Note that, in step S210, the display controller 216 may transmit a signal for displaying the display image generated by the display image generation unit 210 in the display region for captured images supplied from the information processing apparatuses 200, 500, and 700 included in the display screen of the display device 102 to the output unit 214 in accordance with the information on the display region for captured images supplied from the information processing apparatuses 200, 500, and 700 which is supplied from the setting unit 208. In this case, in the display screen of the display device 102, the display image generated by the display image generation unit 210 is displayed in the display region for captured image, and accordingly, the content desired by the user A and the captured images supplied from the information processing apparatuses 200, 500, and 700 are displayed in parallel.
According to the display process shown in FIG. 4, in the display screen of the display device 102, the display image generated by the display image generation unit 210 is displayed in the display region for captured images, and the content desired by the user A which corresponds to the image having the reduced size is displayed in the display region for content. The display image to be displayed in the display region for captured image is generated by extracting portions of the captured images in accordance with the information on the face regions, the result of the obtainment of the number of users, and the information on the display region for captured images such as information on a size of the display region. Therefore, when the size of the display region for captured images is small, the display image to be displayed in the display region for captured images is obtained by removing portions in the captured images which are wasted portions to identify the users, that is, obtained by removing large portions of backgrounds of the captured images, for example. Therefore, since portions of the captured images which are significant portions to identify the users such as portions of the captured images including face feature portions of the users are displayed in the display region for captured images even when the size of the display region for captured images is small, it is not difficult to identify the users. Furthermore, image quality of the display image is not deteriorated. Furthermore, since the image size of the content to be displayed in the content display region is reduced, it is unlikely that a portion of the content is hidden due to the display of the display image. Accordingly, the display of the content and the display of the captured images are appropriately performed in parallel.

As shown in FIGS. 11B and 11C, in the display screen of the display device 102, a display image IM19 or IM21 which is generated by extracting a portion of the image IM13 is displayed in the display region for captured images and content IM20 or IM22 which is desired by the user who uses the display system 100 and which corresponds to an image having a reduced size is displayed in the display region for content. By this, the user who uses the display system 100 may view the content IM20 or IM22 which is not partially hidden and easily identify the three users who use the display system 400 and whose faces are included in the captured image.
Note that, even in a case where two users use the display system 400 and a single user uses the display system 600 as shown in FIG. 10B, the content desired by the user who uses the display system 100 and images IM14 and IM15 captured by the display systems 400 and 600 may be displayed in parallel in the display screen included in the display device 102 as shown in FIGS. 11A to 11D (specifically, FIGS. 11B and 11C). Similarly, even in a case where a single user uses the display system 400, a single user uses the display system 600, and a single user uses another display system (not shown) as shown in FIG. 10C, the content desired by the user who uses the display system 100 and images IM16, IM17, IM18 captured by the display systems 400 and 600 and the other display system may be displayed in parallel in the display screen included in the display device 102 as shown in FIGS. 11A to 11D (specifically, FIGS. 11B and 11C).
Furthermore, similarly, as shown in FIGS. 12A to 12D (specifically, FIGS. 12B and 12C), even when four users use the display system 400 and other systems, the content desired by the user who use the display system 100 and images (not shown) captured by the display system 400 and the other systems may be displayed in parallel in the display screen included in the display device 102.
FIGS. 14A to 14C are diagrams illustrating a fourth example according to the present disclosure. In the fourth example, a case where content desired by the user who uses the display system 100 and an image captured by the display system 400 are displayed in parallel in the display screen of the display device 102 shown in FIG. 2 will be described. Note that, in the fourth example, a case where a single user uses the display system 400 and the user is included in an end portion of an image captured by the display system 400 will be described.
FIG. 14A is a diagram illustrating the image captured by the display system 400. In FIG. 14A, an image IM23 captured by the display system 400 is transmitted to the detection unit 204 included in the information processing apparatus 200 as described above, and the detection unit 204 detects a face region FA4 including a face of the user who uses the display system 400.
FIGS. 14B and 14C are diagrams illustrating the content and the captured image supplied from the information processing apparatus 500 which are displayed in parallel in the display screen included in the display device 102.
As shown in FIG. 14B, a display image IM24 generated by extracting a portion of the captured image IM23 is displayed in a display region for captured images and content IM25 which is desired by the user who uses the display system 100 and which has a reduced image size is displayed in a display region for content.
As shown in FIG. 14B, when the user is included in the end portion of the captured image and the display image IM 24 is generated by extracting a portion of the captured image IM23 including the face region FA4 as a center, the display image IM 24 displayed in the display region for captured images includes an invalid region R1 which is a wasted region.
Therefore, in the fourth example, when the user is included in the end portion of the captured image, the portion of the captured image IM23 is extracted so that the invalid region R1 is not displayed in the display region for captured images whereby a display image IM26 is generated. For example, when the user is included in a right end portion of the captured image as shown in FIG. 14A, a portion of the captured image IM23 is extracted using a right edge of the captured image IM23 as a reference so that the display image IM26 is generated. In this case, as shown in FIG. 14C, the display image IM26 which does not include the invalid region R1 is displayed in the display region for captured images and content IM27 which is desired by the user who uses the display system 100 and which has a reduced image size is displayed in the display region for content in the display screen of the display device 102. Accordingly, the user who uses the display system 100 may be prevented from having a feeling of strangeness and a discomfort feeling.
FIGS. 15A to 15D are diagrams illustrating a fifth example according to the present disclosure. In the fifth example, a case where content desired by the user who uses the display system 100 and an image captured by the display system 400 are displayed in parallel in the display screen of the display device 102 shown in FIG. 2 will be described. Note that, in the fifth example, a case where two users use the display system 400 and the two users are positioned close to each other in an image captured by the display system 400 will be described.
FIG. 15A is a diagram illustrating an image captured by the display system 400 when two users use the display system 400. In FIG. 15A, an image IM28 captured by the display system 400 is transmitted to the detection unit 204 included in the information processing apparatus 200 as described above, and the detection unit 204 detects face regions FA5 and FA6 individually including faces of the two users who use the display system 400.
FIGS. 15B to 15D are diagrams illustrating the content and the captured image supplied from the information processing apparatus 500 which are displayed in parallel in the display screen of the display device 102.
As shown in FIG. 15B, in the display screen of the display device 102, a display image IM29 generated by extracting portions of the captured image IM28 is displayed in a display region for captured images and content IM30 which is desired by the user who uses the display system 100 and which has a reduced image size is displayed in a display region for content.
As shown in FIG. 15B, in a case where the two users are positioned close to each other in the captured image, when the display image IM29 is generated by extracting portions of the captured image IM28 using the face regions FA5 and FA6 as centers, the display image IM29 includes an overlapping region R2 which includes the same images in the display region for captured images.
Therefore, in the fifth example, when the two users are positioned close to each other in the captured image, a display image IM31 is generated by extracting portions of the captured images IM28 such that the overlapping region R2 is not displayed in the display region for captured images. In this case, as shown in FIG. 15C, the display image IM31 which does not include the overlapping region R2 is displayed in the display region for captured images and content IM32 which is desired by the user who uses the display system 100 and which has a reduced image size is displayed in the display region for content in the display screen of the display device 102. Accordingly, the user who uses the display system 100 may be prevented from having a feeling of strangeness and a discomfort feeling.
Furthermore, in the fifth example, when the two users are positioned close to each other in the captured image, it may be determined that a single user uses the display system 400 and a display image IM33 may be generated by extracting a portion of the captured image IM28 so that at least face feature portions of the two users are included in the display image IM33. Also in this case, as shown in FIG. 15D, the display image IM33 which does not include the overlapping region R2 is displayed in the display region for captured images and content IM34 which is desired by the user who uses the display system 100 and which has a reduced image size is displayed in the display region for content in the display screen of the display device 102. The display image IM31 shown in FIG. 15C is generated by arranging two images, and on the other hand, the display image IM33 shown in FIG. 15D is a single image, that is, an image generated by integrating the two images. Accordingly, the user who uses the display system 100 may be prevented from having a feeling of strangeness and a discomfort feeling.
FIGS. 16A to 16F are diagrams illustrating a sixth example according to the present disclosure. In the sixth example, a setting of a region to be extracted from a captured image will be described.
