Abstract
This invention provides an electronic apparatus which comprises a TIME-CODE terminal configured to output a time code signal which an external apparatus utilizes to perform synchronization related to a video, and a control unit configured to output a time code signal in which a bit in a predetermined field in the time code signal is set to a predetermined value, from the TIME-CODE terminal.
Claims9
An electronic apparatus, comprising:
- an image capturing unit;
- a TIME-CODE terminal configured to output a time code signal which an external apparatus utilizes to perform synchronization related to a video, the time code signal including first fields storing data specifying a frame, second fields storing data set by a user and a third field storing a sync word;
- a determination unit configured to determine whether an instruction input of high speed synchronization is performed by a user or a predetermined condition is satisfied;
- and
- a control unit configured to, in accordance with a result of the determination by the determination unit, generate the time code signal and output the generated time code signal to the external apparatus via the TIME-CODE terminal,
- wherein the control unit,
- in a case that the determination unit determines neither the instruction input of high speed synchronization is performed by the user nor the predetermined condition is satisfied, generates the time code signal in which the second fields store data set by the user, and
- in a case that the determination unit determines that the instruction input of high speed synchronization is performed by the user or the predetermined condition is satisfied, generates the time code signal in which all of bits in the second fields are set as “1” regardless of the data set by the user.
A method for controlling an electronic apparatus having an image capturing unit and a TIME-CODE terminal configured to output a time code signal which an external apparatus utilizes to perform synchronization related to a video, the time code signal including first fields storing data specifying a frame, second fields storing data set by a user and third field storing a sync word, the method comprising:
- determining whether an instruction input of high speed synchronization is performed by a user;
- and
- in accordance with a result of the determination in the determining, generating the time code signal and outputting the generated time code signal to the external apparatus via the TIME-CODE terminal,
- wherein, in a case that a predetermined condition is not satisfied and it is determined in the determining that the instruction input of high speed synchronization is not performed by the user, the time code signal in which the second fields store data set by the user is generated, and
- in a case that it is determined in the determining that the instruction input of high speed synchronization is performed by the user, the time code signal in which all of bits in the second fields are set as “1” regardless of the data set by the user is generated.
A non-transitory computer-readable storage medium storing a program which, when read and executed by a computer of an electronic apparatus having an image capturing unit and a TIME-CODE terminal configured to output a time code signal which an external apparatus utilizes to perform synchronization related to a video, causes the electronic apparatus to execute the steps of a method for controlling the electronic apparatus, the time code signal including first fields storing data specifying a frame, second fields storing data set by a user and third field storing a sync word, the method comprising:
- determining whether an instruction input of high speed synchronization is performed by a user or a predetermined condition is satisfied;
- and
- in accordance with a result of the determination in the determining, generating the time code signal and outputting the generated time code signal to the external apparatus via the TIME-CODE terminal,
- wherein, in a case that it is determined in the determining neither the instruction input of high speed synchronization is performed by the user nor the predetermined condition is satisfied, the time code signal in which the second fields store data set by the user is generated, and
- in a case that it is determined in the determining that the instruction input of high speed synchronization is performed by the user or the predetermined condition is satisfied, the time code signal in which all of bits in the second fields are set as “1” regardless of the data set by the user is generated.
