Image apparatus with locking operation for serial data

A communication method between an image sensor configured to acquire image data and to transmit serial data, via a transmission unit, based on a clock embedded procedure, the serial data including the image data, and a signal processing unit including a reception unit configured to receive the serial data and a reference clock, the reception unit including a locking unit and a detection unit, the communication method comprising:

• performing a locking operation to lock a serial clock to the reference clock and the serial data at the reception unit;
• detecting a locking result of the locking operation;
• and
• performing the locking operation again at the reception unit based on a detection result detected by the detecting, and
• wherein the locking operation performed and the locking operation is performed again within a period from when accumulation of charges in the image sensor corresponding to one frame of image data is started to when reading the one frame of image data is started.

An imaging apparatus comprising:

• an image sensor configured to acquire image data and to transmit serial data, via a transmission unit, based on a clock embedded procedure, the serial data including the image data;
• and
• a controller having a processor which executes instructions stored in a memory, the controller being configured to function as:
• a reception unit configured to receive the serial data and a reference clock, the reception unit including a locking unit and a detection unit,
• a generator configured to generate a serial clock, and
• a control unit configured to control the reception unit,
• wherein the locking unit is configured to perform a locking operation to lock the serial clock to the reference clock and the serial data and the detection unit is configured to detect a lock state of the locking unit,
• wherein the control unit controls performing of the locking operation again by the locking unit in a case where locking is not achieved, based on a detection result detected by the detection unit, and
• wherein the control unit controls the locking unit to perform the locking operation within a period from when reading a first frame of a live view image is finished to when reading a second frame next to the first frame of the image is started.
