Abstract
An imaging apparatus allows a clock data recovery device to reestablish reception of data even when the clock data recovery device has failed to lock a phase. A reception unit includes a locking unit configured to perform a locking operation for receiving the data and a detection unit configured to detect a lock state of the locking unit. A control unit controls performing of the locking operation again by the locking unit in a case where a lock is not achieved, based on a detection result detected by the detection unit.
Claims17
An imaging apparatus comprising:
- an image sensor including a transmission unit configured to transmit serial data based on a clock embedded procedure, the serial data having 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,
- a control unit configured to control the reception unit, and
- an image processing unit configured to be used on the image data included in the serial data received by the reception unit,
- wherein the reception unit includes a locking unit configured to perform a locking operation for receiving the data and a detection unit configured to detect a lock state of the locking unit, and
- 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.
A communication method between an image sensor including a transmission unit configured to transmit serial data based on a clock embedded procedure, the serial data having image data, and a signal processing unit including a reception unit configured to receive the serial data, the communication method comprising:
- performing, as locking, a locking operation for receiving the data at the reception unit;
- detecting a locking result of the locking;
- and
- performing, as controlling, the locking operation again at the reception unit based on a detection result detected by the detecting.
