An image capturing apparatus capable of guaranteeing the authenticity of contents while reducing the calculation load of a hash value of an image file. The image capturing apparatus generates an image file, and performs processing for reducing a file size of the image file. A hash value generation section calculates a hash value by applying a hash function to the processed image file. Reduction processing information indicating a method of reducing the file size is generated, and the image file, the hash value, and the reduction processing information are transmitted in a state associated with each other, to a management system that registers data associated with the image file including the hash value in a blockchain.

Image capturing apparatus capable of guaranteeing authenticity of digital image, management system, control method, and storage medium

A management system that manages contents associated with a hash value registered in a blockchain. A controller of the management system receives contents as a target of authenticity determination and an identification number for identifying authentic contents used as a reference for determining the authenticity of the target contents. The controller determines the authenticity of the contents as the target of the authenticity determination by comparing a hash value generated from the contents as the target of the authenticity determination and a hash value, registered in the blockchain, of authentic contents indicated by the received identification number, and notifies a result of the authenticity determination. In a case where it is determined that the contents as the target of the authenticity determination are not authentic, the controller notifies information on the authentic contents associated with the identification number.

Management system that determines authenticity of contents, communication apparatus, management method, method of controlling communication apparatus, and storage medium

An imaging device includes: a controller configured to perform control of each of a moving image capturing mode, in which a captured moving image is recorded as a moving image file, and a live distribution mode, in which a captured moving image is live-distributed to an external device; and an operation interface configured to be used for a user to input a stop instruction. In a case where the controller receives the stop instruction from the operation interface in the live distribution mode, the controller performs control of executing stopping confirmation processing for confirming with the user whether to stop moving image capturing before stopping the moving image capturing. In a case where the controller receives the stop instruction from the operation interface in the moving image capturing mode, the controller performs control of stopping the moving image capturing without executing the stopping confirmation processing.

Imaging device, control method of imaging device, and non-transitory computer readable medium

An image capture apparatus comprises a display unit that displays a captured image, an output unit that outputs the image to an external device, a processing unit capable of switching and executing a plurality of operations that include a first operation of capturing the image with an image capturing mode setting during shooting standby, and a second operation of capturing the image with the same image capturing mode setting regardless of whether it is during shooting standby or during shooting, and a control unit that, when an output of the image to the external device is not being performed, permits the processing unit to perform the first operation, and when an output of the image to the external device is being performed, prohibits the processing unit to perform the first operation.
