摘要： There is provided an image pickup apparatus that is capable of eliminating the influence of errors attributed to differences in characteristics between lens devices attached to the image pickup apparatus such as a camera or errors attributed to differences in characteristics between optical component elements within the main body of the image pickup apparatus, to thereby enable setting a proper exposure compensation value. An image pickup device receives light passing through a lens device and outputs an image signal, and a photometric sensor receives the light passing through the lens device and outputs luminance information. A main control circuit sets an exposure compensation value according to an output from the photometric sensor. Specifically, the main control circuit sets a first exposure compensation value according to the luminance information outputted from the photometric sensor, to cause the image pickup device to carry out a first storage of the light passing through the lens device, based on the set first exposure compensation value, and sets a second exposure compensation value according to the result of the first storage, to cause the image pickup device to carry out a second storage of the light passing through the lens device, based on the set second exposure compensation value.

摘要： When communication is made between a camera and an interchangeable lens by a conventional synchronization method, an operation for checking Busy is required between communications, and operating performances of the camera and interchangeable lens may not be occasionally improved. Provided is a camera and interchangeable lens system in which a communication method between a camera and an interchangeable lens can be changed to one of synchronous communication and asynchronous communication. The synchronous communication is made first while the camera serves as a master. The camera measures a time interval of a signal pulse output from the lens at a predetermined time interval in response to a command from the camera to the interchangeable lens for change of the communication to the asynchronous communication. The camera determines a baud rate for the asynchronous communication and then changes the communication method between the camera and the interchangeable lens to the asynchronous communication.
