Abstract

The present invention provides a camera system including plural camera heads and a camera main unit to which any of the camera heads is attached. Each of the camera heads includes a sensitivity information storing unit. Each time any one of the camera heads is attached to the camera main unit, a CPU of the camera main unit obtains sensitivity information stored in the sensitivity information storing unit. Based on the obtained information, the CPU causes a LCD unit to display a sensitivity settable range on a display screen so as to inform a user of the property of the CCD of the camera head.

Claims

1. A camera system that includes:

plural types of camera heads each incorporating therein an image taking optical system and an image pickup device and having a sensitivity settable range unique to each one of the camera heads; and

a camera main unit to which any of the plural types of camera heads is interchangeably attached and which receives an image signal from the attached camera head and performs signal processing,

wherein the camera head comprises;

a sensitivity range recognition section that recognizes a sensitivity settable range of a camera head attached to the camera main unit; and

a display section that displays contents according to the sensitivity settable range recognized by the sensitivity range recognition section.

2. The camera system according to claim 1, wherein the display section displays settable sensitivity values, and

the camera main unit comprises:

a sensitivity setting section that sets any of the settable sensitivity values according to an operation; and

an image taking section that takes an image with the sensitivity value set by the sensitivity setting section.

3. The camera system according to claim 2, wherein the display section displays, in addition to the settable sensitivity values, unsettable sensitivity values in a mode distinguished from the settable sensitivity values.

4. The camera system according to claim 1, wherein the display section displays settable exposure correction values, and

the camera main unit comprises:

an exposure correction setting section that sets any of the settable exposure correction values according to an operation; and

an image taking section that takes an image with exposure corrected according to the exposure correction value set by the exposure correction setting section.

5. The camera system according to claim 4, wherein the display section displays, in addition to the settable exposure correction values, unsettable exposure correction values in a mode distinguished from the settable exposure correction values.

6. The camera system according to claim 1, wherein the display section displays settable shutter speeds, and

the camera main unit comprises:

a shutter speed setting section that sets any of the settable shutter speeds according to an operation; and

an image taking section that takes an image at the shutter speed set by the shutter speed setting section.

7. The camera system according to claim 6, wherein the display section displays, in addition to the settable shutter speeds, unsettable shutter speeds in a mode distinguished from the settable shutter speeds.
