Abstract
A camera system is capable of exactly catching the subject at the time of release operation by the imaging device of the camera head in accordance with the release button operation at the side of the camera main frame, even if the camera head and the camera main frame are not formed in a unitary body. There are provided two dedicated lines for supplying to a head CPU a release signal according to the half-depression and a release signal according to the full-depression, respectively. Other signals are transmitted via serial interfaces to be driven by three-wire serial drivers. Only the release signals are transmitted from the camera main frame via the two dedicated lines to the camera head.
Claims7
A camera system comprising:
- a camera head comprising an imaging optical system and an imaging device;
- and a camera main frame that receives an image signal from the camera head via an interface for transferring signals between the camera main frame and the camera head so as to perform signal processing,
- wherein the camera head comprises a first CPU and a timing generator that supplies exposure start signal and exposure completion signal according to a shutter speed of an electronic shutter to the imaging device in accordance with a control of the first CPU,
- the camera main frame comprises a second CPU and a release button for communicating a signal of a photography start to the second CPU, and
- the camera system further comprises a dedicated line connecting the camera main frame with the camera head, the dedicated line supplying a release signal according to depression of the release button to the first CPU of the camera head when the release signal is supplied to the second CPU in accordance with the depression of the release button.
A camera system comprising:
- a camera head comprising an imaging optical system and an imaging device;
- and a camera main frame that receives an image signal from the camera head via an interface for transferring signals between the camera main frame and the camera head so as to perform signal processing,
- wherein the camera head has a timing generator that supplies exposure start signal and exposure completion signal to the imaging device,
- the camera main frame has a flash emission section for emitting a flash in synchronism with photography, and
- the camera system further comprises a dedicated line connecting the camera main frame with the camera head, wherein a light emission instruction signal is supplied from the camera head via the dedicated line to the camera main frame so that the flash emission section emits a flash during an exposure by the imaging device.
