Terminal device, image shooting system and image shooting method
View Patent ↗A terminal device used for stereo imaging includes: an image shooting unit; a communication unit that receives a first image of a first angular field from an external terminal device; and a determination unit that determines the image shooting range relationship between the first image received by the communication unit and a second image of a second angular field shot by the image shooting unit, the second angular field being wider than the first angular field.
1. A terminal device, comprising:
an image shooting device;
a display device;
a communication device that receives a first image having a first field angle from an external terminal device with an image shooting function; and
a controller, configured to operate as a determination unit that determines a correspondence relation between an image shooting range of the external terminal device and that of the image shooting device based on corresponding image areas between the first image received by the communication device and a second image having a second field angle shot by the image shooting device, the second field angle being wider than the first field angle,
wherein the determination unit detects an area corresponding to the first image from the second image, and based on the position of the detected area on the second image, determines the image shooting range relationship between the first and second images, and
wherein the determination unit causes the display device to superpose and display an image that indicates the range of the detected area and the second image.
2. The terminal device according to claim 1 , wherein the determination unit causes the communication device to transmit a notice indicating the determination result of the image shooting range relationship between the first and second images to the external terminal device.
3. The terminal device according to claim 1 ,
wherein the controller is further configured to operate as a clipping unit that clips the detected area from the second image, and
wherein the determination unit causes the communication device to transmit the image clipped by the clipping unit to the external terminal device.
4. The terminal device according to claim 1 ,
wherein the controller is further configured to operate as
a reduction unit that reduces the second image to obtain a reduced image, and
a clipping unit that clips the detected area from the second image,
and wherein the determination unit causes the display device to superpose and display the image that indicates the range of the detected area and the reduced image, and causes the communication device to transmit the image clipped by the clipping unit to the external terminal device.
5. An image shooting system comprising:
a display device;
a first image shooting device; and
a second image shooting device that can communicate with the first image shooting device,
wherein the first image shooting device includes:
a first image sensor; and
a first communication device that transmits a first image of a first field angle that is shot by the first image sensor,
wherein the second image shooting device includes:
a second image sensor;
a second communication device that receives the first image from the first communication device; and
a controller that controls operation of the second image shooting device, the controller configured to operate as a determination unit that determines a correspondence relation between an image shooting range of the external terminal device and that of the image shooting device based on corresponding image areas between the first image received by the second communication device and a second image having a second field angle that is shot by the second image sensor, the second field angle being wider than the first field angle,
wherein the determination unit detects an area corresponding to the first image from the second image, and based on the position of the detected area on the second image, determines the image shooting range relationship between the first and second images, and
wherein the determination unit causes the display device to superpose and display an image that indicates the range of the detected area and the second image.
6. An image shooting method, comprising:
receiving a first image of a first field angle from an external terminal device;
determining a correspondence relation between an image shooting range of the external terminal device and that of an image shooting device, different from the external terminal device, based on corresponding image areas between the received first image and a second image of a second field angle that is shot by the image shooting device, the second field angle being wider than the first field angle;
detecting an area corresponding to the first image from the second image, and based on the position of the detected area on the second image, determines the image shooting range relationship between the first and second images; and
causing a display device to superpose and display an image that indicates the range of the detected area and the second image.
7. An image shooting method, comprising:
displaying a first image of a first field angle, shot by an image shooting device, on a display device;
transmitting the first image to an external terminal device;
receiving, from the external terminal device, a result of a determination of a correspondence relation between an image shooting range of the external terminal device and that of the image shooting device based on corresponding image areas between the first image and a second image of a second field angle that is wider than the first angular field; and
causing the display device to display a predetermined image in accordance with the determination result, the predetermined image comprising an image that indicates a range of a detected area and the second image, the detected area being an area corresponding to the first image from the second image, and said determination including an image shooting range relationship between the first and second images based on the position of the detected area on the second image.
8. A program recorded on a non-transient, computer-readable medium that, upon being read and executed by a computer, causes the computer to execute:
a process of receiving a first image of a first field angle from an external terminal device;
a process of determining a correspondence relation between an image shooting range of the external terminal device and that of an image shooting device, different from the external terminal device, based on corresponding image areas between the received first image and a second image of a second field angle that is shot by an image shooting device, the second field angle being wider than the first field angle;
a process of detecting an area corresponding to the first image from the second image, and based on the position of the detected area on the second image, determines the image shooting range relationship between the first and second images; and
a process of causing a display device to superpose and display an image that indicates the range of the detected area and the second image.
9. The terminal device according to claim 2 ,
wherein the controller is further configured to operate as a clipping unit that clips the detected area from the second image, and
wherein the determination unit causes the communication device to transmit the image clipped by the clipping unit to the external terminal device.
