no. 1 Embodiment approach
[0040] First, in figure 1 The configuration of the imaging device according to the first embodiment of the present invention is shown in the following description.
[0041] Here, as an example of the imaging device, a camera system in which an interchangeable imaging lens (hereinafter referred to as an interchangeable lens) is combined with a camera body will be described as an example.
[0042] like figure 1 As shown, the camera system as the imaging device according to the first embodiment of the present invention has: a lens module 1, a camera module 2, a RAM 3, an image signal processing circuit 4, a microcomputer (hereinafter referred to as a microcomputer) 5, a ROM6, an EEPROM7, Mode setting switch 8, storage medium 9, etc. The lens module 1 is disposed on the side of the interchangeable lens, and other components are disposed on the side of the camera body to which the interchangeable lens can be mounted. The lens module 1 and the camera module 2 can be freely atta...
no. 2 Embodiment approach
[0115] In the imaging device according to the second embodiment of the present invention, the installation equipment has Figure 9 Correspondence table of WB correction coefficient and its characteristics to replace the CCD camera module equipped with the above Image 6 The WB correction coefficient correspondence table and its characteristics for the case of the CCD camera module will be described. As the CCD of this imaging module, a CCD having a narrower interval between adjacent pixels than the imaging element 2a (hereinafter referred to as a narrow-pitch module) is used.
[0116] Here, if figure 1 As shown, the camera module and the lens module are electrically connected through the communication part 1d. In addition, the camera module is electrically connected to the microcomputer and ROM 3 of the camera device through the communication unit 10 . An example of the communication unit 1d and the communication unit 10 is that the camera module can be detached by being c...
no. 3 Embodiment approach
[0124] In the imaging device according to the third embodiment of the present invention, the installation equipment has Figure 10 The WB correction coefficient correspondence table and its characteristics of the lens module of the zoom lens (hereinafter referred to as the zoom lens module) to replace the above Figure 5 The case of the WB correction coefficient correspondence table will be described.
[0125] Here, if figure 1 As shown, the camera module and the zoom lens module are electrically connected through the communication unit 1d. This communication part 1d is detachable by being comprised as a connector like 2nd Embodiment.
[0126] In the imaging device according to the third embodiment of the present invention, as the first table, Figure 10 Correspondence table of WB correction coefficients, and as the second table Image 6 The WB correction coefficient correspondence table is used to calculate the digital gain, and the signal of each color is amplified acco...
