Abstract
A transmission apparatus configured to transmit image data to a reception apparatus through a network, in which a setting value for generating captured data and a setting value for generating image data by an encoding unit are updated according to reception of a command that sets the setting value for generating the captured data by the image capturing unit. When the setting value for generating the captured data is updated according to the received command, notification is performed through the network regardless of a restart process is performed.
Claims71
An image capturing system comprising:
- an image capturing apparatus configured to transmit image data to an image receiving apparatus;
- and
- the image receiving apparatus configured to receive the image data from the image capturing apparatus,
- wherein the image capturing apparatus comprises:
- an image capturing unit configured to generate the image data;
- a communication unit configured to receive a command for changing Video Source Mode to define at least a frame rate and resolution related to the image data, from an external apparatus via a network;
- and
- a control unit configured to perform a reboot process and cause the communication unit to transmit a predetermined notification to the external apparatus, in a case where Video Source Mode being set in the image capturing apparatus is changed from first Video Source Mode to second Video Source Mode different from the first Video Source Mode, in response to the command for changing Video Source Mode received by the communication unit,
- wherein the control unit is configured to perform control not to perform the reboot process in a case where Video Source Mode being set in the image capturing apparatus is changed from the first Video Source Mode to third Video Source Mode different from the first Video Source Mode and the second Video Source Mode in response to the command for changing Video Source Mode received by the communication unit,
- wherein the control unit is configured to cause the communication unit to transmit, to the external apparatus, information indicating that the second Video Source Mode is a target on which the reboot process is to be performed and information indicating that the third Video Source Mode is not a target on which the reboot process is to be performed, in response to a request command from the external apparatus, and
- wherein the image receiving apparatus comprises a display control unit configured to cause a display unit to display a setting screen for designating at least one of the frame rate and the resolution.

An image transmission method comprising:
- transmitting image data to an image receiving apparatus from an image capturing apparatus that generates the image data;
- receiving the image data from the image capturing apparatus by the image receiving apparatus;
- receiving a command from an external apparatus via a network by the image receiving apparatus, the command being for changing Video Source Mode to define at least a frame rate and resolution related to the image data;
- and
- performing a reboot process and transmitting a predetermined notification to the external apparatus from the image capturing apparatus, in a case where Video Source Mode being set in the image capturing apparatus is changed from first Video Source Mode to second Video Source Mode different from the first Video Source Mode, in response to the command for changing Video Source Mode received,
- wherein the reboot process is not performed in a case where Video Source Mode being set in the image capturing apparatus is changed from the first Video Source Mode to third Video Source Mode different from the first Video Source Mode and the second Video Source Mode in response to the command for changing Video Source Mode received,
- wherein information indicating that the second Video Source Mode is a target on which the reboot process is to be performed and information indicating that the third Video Source Mode is not a target on which the reboot process is to be performed is transmitted to the external apparatus from the image capturing apparatus, in response to a request command from the external apparatus, and
- wherein the image receiving apparatus displays a setting screen for designating at least one of the frame rate and the resolution.

A non-transitory computer-readable storage medium which stores a program for executing an image transmission method, the method comprising:
- transmitting image data to an image receiving apparatus from an image capturing apparatus that generates the image data;
- receiving the image data from the image capturing apparatus by the image receiving apparatus;
- receiving a command from an external apparatus via a network by the image receiving apparatus, the command being for changing Video Source Mode to define at least a frame rate and resolution related to the image data;
- and
- performing a reboot process and transmitting a predetermined notification to the external apparatus from the image capturing apparatus, in a case where Video Source Mode being set in the image capturing apparatus is changed from first Video Source Mode to second Video Source Mode different from the first Video Source Mode, in response to the command for changing Video Source Mode received,
- wherein the reboot process is not performed in a case where Video Source Mode being set in the image capturing apparatus is changed from the first Video Source Mode to third Video Source Mode different from the first Video Source Mode and the second Video Source Mode in response to the command for changing Video Source Mode received,
- wherein information indicating that the second Video Source Mode is a target on which the reboot process is to be performed and information indicating that the third Video Source Mode is not a target on which the reboot process is to be performed is transmitted to the external apparatus from the image capturing apparatus, in response to a request command from the external apparatus, and
- wherein the image receiving apparatus displays a setting screen for designating at least one of the frame rate and the resolution.
5 more elements
An image capturing system comprising:
- an image capturing apparatus configured to transmit image data to an image receiving apparatus;
- and
- the image receiving apparatus configured to receive the image data from the image capturing apparatus,
- wherein the image capturing apparatus comprises a computer executing instructions that, when executed by the computer, cause the computer to function as:
- an image capturing unit configured to generate the image data;
- and
- a control unit configured to control a communication unit which receives a command for changing Video Source Mode to define at least a frame rate and resolution related to the image data, from an external apparatus via a network,
- wherein the control unit is configured to perform a reboot process and cause the communication unit to transmit a predetermined notification to the external apparatus, in a case where Video Source Mode being set in the image capturing apparatus is changed from first Video Source Mode to second Video Source Mode different from the first Video Source Mode, in response to the command for changing Video Source Mode received by the communication unit,
- wherein the control unit is configured to perform control not to perform the reboot process in a case where Video Source Mode being set in the image capturing apparatus is changed from the first Video Source Mode to third Video Source Mode different from the first Video Source Mode and the second Video Source Mode, in response to the command for changing Video Source Mode received by the communication unit,
- wherein the control unit is configured to cause the communication unit to transmit, to the external apparatus, information indicating that the second Video Source Mode is a target on which the reboot process is to be performed and information indicating that the third Video Source Mode is not a target on which the reboot process is to be performed, in response to a request command from the external apparatus,
- wherein the image receiving apparatus comprises a computer executing instructions that, when executed by the computer, cause the computer to function as a display control unit, and
- wherein the display control unit is configured to cause a display unit to display a setting screen for designating at least one of the frame rate and the resolution.
