Abstract

A camera main body includes a mount, a solid-state imaging element, a main body controller, a main body side storage section, and a rear surface display section. In the mount, a plurality of types of interchangeable lenses are selectively mounted. The main body controller acquires a lens type of each interchangeable lens mounted on the mount, counts the number of mounting operations and the number of imaging operations for each lens type of the interchangeable lens, and stores the result in the main body side storage section. In a case where the interchangeable lens is mounted on the mount, the main body controller changes a setting menu to be displayed on the rear surface display section in accordance with the lens type acquired from the interchangeable lens, and the number of mounting operations and the number of imaging operations corresponding to the lens type.

First claim

What is claimed is:

1. An imaging device comprising:
a lens mounting section on which a plurality of types of interchangeable lenses are selectively mounted;
an imaging section that performs imaging in a state where the interchangeable lens is mounted on the lens mounting section;
a lens type detection section that detects a lens type of the interchangeable lens mounted on the lens mounting section;
a controller that counts the number of mounting operations of the interchangeable lens on the lens mounting section and the number of imaging operations of the imaging section, for each lens type of the interchangeable lens detected by the lens type detection section, and stores the result in a storage section provided in a device main body or the interchangeable lens;
a menu display section that displays a setting menu for setting an imaging function of the imaging section; and
a setting menu change section that changes, in a case where the interchangeable lens is mounted on the lens mounting section, the setting menu in accordance with the lens type detected by the lens type detection section and the number of mounting operations, and the number of imaging operations corresponding to the lens type detected by the lens type detection section among the number of mounting operations and the number of imaging operations stored in the storage section.

2. The imaging device according to claim 1 ,
wherein the menu display section displays a plurality of display setting items selected from a plurality of setting items, as the setting menu.

3. The imaging device according to claim 2 ,
wherein the setting menu change section changes the display setting items to be displayed as the setting menu, in accordance with the lens type and the number of mounting operations.

4. The imaging device according to claim 3 ,
wherein the setting menu change section uses the number of mounting operations weighted on the basis of a weight value proportional to the number of imaging operations.

5. The imaging device according to claim 2 ,
wherein the setting menu change section changes an order of the display setting items to be displayed as the setting menu, in accordance with the lens type and the number of mounting operations.

6. The imaging device according to claim 2 ,
wherein the setting menu change section changes the number of the display setting items to be displayed as the setting menu, in accordance with the lens type and the number of mounting operations.

7. The imaging device according to claim 2 ,
wherein the setting menu change section changes the display setting items to be displayed as the setting menu, in accordance with the lens type and the number of imaging operations.

8. The imaging device according to claim 7 ,
wherein the setting menu change section uses the number of imaging operations weighted on the basis of a weight value proportional to the number of mounting operations.

9. The imaging device according to claim 2 ,
wherein the setting menu change section changes an order of the display setting items to be displayed as the setting menu, in accordance with the lens type and the number of imaging operations.

10. The imaging device according to claim 2 ,
wherein the setting menu change section changes the number of the display setting items to be displayed as the setting menu, in accordance with the lens type and the number of imaging operations.

11. The imaging device according to claim 1 ,
wherein the controller counts an accumulated mounting time when the interchangeable lens is mounted on the lens mounting section for each lens type of the interchangeable lens detected by the lens type detection section, and stores the result in the storage section, and
wherein the setting menu change section changes the setting menu in accordance with the accumulated mounting time in addition to the number of mounting operations and the number of imaging operations.

12. The imaging device according to claim 11 ,
wherein the setting menu change section changes display setting items to be displayed as the setting menu, in accordance with the lens type and the accumulated mounting time.

13. The imaging device according to claim 12 ,
wherein the setting menu change section uses the accumulated mounting time weighted using a weight value proportional to any one of the number of mounting operations or the number of imaging operations.

14. The imaging device according to claim 11 ,
wherein the setting menu change section changes an order of display setting items to be displayed as the setting menu, in accordance with the lens type and the accumulated mounting time.

15. The imaging device according to claim 11 ,
wherein the setting menu change section changes the number of display setting items to be displayed as the setting menu, in accordance with the lens type and the accumulated mounting time.

16. The imaging device according to claim 11 ,
wherein in a case where the lens type detected by the lens type detection section is a specific lens type and at least one of the number of mounting operations, the accumulated mounting time, or the number of imaging operations corresponding to the specific lens type is equal to or greater than a setting value, the setting menu change section changes the setting menu.

17. The imaging device according to claim 11 ,
wherein in a case where the lens type detected by the lens type detection section is a specific lens type and a total sum of at least one of the numbers of mounting operations, the accumulated mounting times, or the numbers of imaging operations corresponding to a plurality of types of the interchangeable lenses that are the specific lens types is equal to or greater than a setting value, the setting menu change section changes the setting menu.

18. The imaging device according to claim 17 ,
wherein in a case where total sums of any two or more of the numbers of mounting operations, the accumulated mounting times, or the numbers of imaging operations corresponding to the plurality of types of interchangeable lenses that are the specific lens types are equal to or greater than the setting values, the setting menu change section resets the setting menu to an initial value, and
wherein in a case where the setting menu is reset to the initial value by the setting menu change section, the controller resets the number of counting operations stored in the storage section to an initial value.

19. The imaging device according to claim 18 , further comprising:
a history storage section different from the storage section provided in the device main body or the interchangeable lens,
wherein in a case where the setting menu is reset to the initial value by the setting menu change section, the controller resets the number of counting operations stored in the storage section to the initial value, and stores the number of mounting operations, the accumulated mounting time, and the number of imaging operations of the imaging section before resetting stored for each lens type in the history storage section.

20. The imaging device according to claim 1 , further comprising:
a position information acquisition section that acquires position information; and
a time point acquisition section that acquires a mounting time point when the interchangeable lens is mounted on the lens mounting section, a mounting release time point when the interchangeable lens is detached from the lens mounting section, and an imaging time point of the imaging section,
wherein the controlle
