Abstract

There is provided a display apparatus. A reception unit receives a captured image from an image capturing apparatus. A display unit displays the captured image. A detection unit detects an attitude of the display apparatus. A transmission unit, while the display unit is displaying the captured image, transmits attitude information to the image capturing apparatus in response to an instruction from a user. The attitude information indicates the attitude detected by the detection unit.

Claims

1. A display apparatus, comprising:

at one processor or at least one circuit, which functions and operates as;

a reception unit configured to receive a captured image from an image capturing apparatus;

a display unit configured to display the captured image;

a detection unit configured to detect an attitude of the display apparatus; and

a transmission unit configured to, while the display unit is displaying the captured image, transmit attitude information to the image capturing apparatus in response to an instruction from a user, the attitude information indicating the attitude detected by the detection unit,

wherein the display unit displays, together with the captured image, auxiliary information indicating the attitude detected by the detection unit,

the auxiliary information includes two auxiliary lines that are displayed parallel to an up-down direction of the display unit when a tilt angle of the display apparatus has a reference value,

the more an upper portion of the display unit is tilted backward, the larger an interval between lower portions of the two auxiliary lines becomes compared to an interval between upper portions of the two auxiliary lines, and

the more the upper portion of the display unit is tilted forward, the smaller the interval between the lower portions of the two auxiliary lines becomes compared to the interval between the upper portions of the two auxiliary lines.

2. The display apparatus according to claim 1, wherein

the auxiliary information includes a horizontal auxiliary line that represents a horizontal line perpendicular to a, gravitational direction in the display apparatus, the horizontal auxiliary line being relative to a rotation angle of the display apparatus around a rotation axis orthogonal to a display surface of the display unit.

3. The display apparatus according to claim 1, wherein

the attitude information includes information indicating a gravitational direction detected by the detection unit, or information related to an angle with respect to the gravitational direction around a rotation axis orthogonal to a display surface of the display unit.

4. The display apparatus according to claim 1, wherein

the attitude information includes information indicating a gravitational direction detected by the detection unit, or information related to an angle of a display surface of the display unit with respect to the gravitational direction.

5. The display apparatus according to claim 1, wherein

the reception unit receives image capturing apparatus attitude information indicating an attitude of the image capturing apparatus, and

based on the image capturing apparatus attitude information, the display unit displays, together with the captured image, information indicating a horizontal direction in the image capturing apparatus.

6. The display apparatus according to claim 1, wherein

the display apparatus is a mobile terminal that can be held in a hand of the user.

7. The display apparatus cording to claim 1, wherein

the transmission unit transmits the attitude information as information for applying cutout and rotation processing to the captured image.

8. The display apparatus according to claim 1, wherein

after the attitude information has been transmitted to the image capturing apparatus, the reception unit receives the captured image that has been corrected based on the attitude information, and

the display unit displays the corrected captured image.

9. An image capturing system including a display apparatus and an image capturing apparatus, the display apparatus comprising:

at least one processor or at least one circuit, which functions and operates as;

a first reception unit configured to receive a captured image from the image capturing apparatus;

a display unit configured to display the captured image;

a detection unit configured to detect an attitude of the display apparatus; and

a first transmission unit configured to, while the display unit is displaying the captured image, transmit attitude information to the image capturing apparatus in response to an instruction from a user, the attitude information indicating the attitude detected by the detection unit,

wherein the display unit displays, together with the captured image, auxiliary information indicating the attitude detected by the detection unit,

the auxiliary information includes two auxiliary lines that are displayed parallel to an up-down direction of the display unit when a tilt angle of the display apparatus has a reference value,

the more an upper portion of the display unit is tilted backward, the larger an interval between lower portions of the two auxiliary lines becomes compared to an interval between upper portions of the two auxiliary lines, and

the more the upper portion of the display unit is tilted forward, the smaller the interval between the lower portions of the two auxiliary lines becomes compared to the interval between the upper portions of the two auxiliary lines, the image capturing apparatus comprising;

at least one processor or at least one circuit, which functions and operates as;

an image capturing unit configured to generate the captured image;

a second transmission unit configured to transmit the captured image to the display apparatus;

a second reception unit configured to receive the attitude information indicating the attitude of the display apparatus from the display apparatus; and

a processing unit configured to apply specific processing to the captured image based on the attitude information received by the second reception of the image capturing apparatus, and record the captured image.

10. A control method for a display apparatus including a display unit and an attitude detection unit the control method comprising:

receiving a captured image from an image capturing apparatus;

displaying the captured image on the display unit;

detecting an attitude of the display apparatus with the attitude detection unit; and

while displaying the captured image on the display unit, transmitting attitude information to the image capturing apparatus in response to an instruction from a user, the attitude information indicating the attitude detected by the detecting,

wherein the displaying displays, together with the captured image, auxiliary information indicating the attitude detected by the attitude detection unit,

the auxiliary information includes two auxiliary lines that are displayed parallel to an up-down direction of the display unit when a tilt angle of the display apparatus has a reference value,

the more an upper portion of the display unit is tilted backward, the larger an interval between lower portions of the two auxiliary lines becomes compared to an interval between upper portions of the two auxiliary lines, and

the more the upper portion of the display unit is tilted forward, the smaller the interval between the lower portions of the two auxiliary lines becomes compared to the interval between the upper portions of the two auxiliary lines.

11. A non-transitory computer-readable storage medium which stores a program for causing at least one processor or at least one circuit in a computer to function and operate as a display apparatus comprising:
