Abstract

A matte box for a camera includes a frame, a filter tray holder having at least one stage configured to receive a filter, and at least one filter tray configured to support the filter. The at least one filter tray is removably coupled to the filter tray holder at the at least one stage so that the filter is positioned in front of a lens of the camera. The matte box also includes a filter information system that has an identification tag coupled to the at least one filter tray and/or the filter. The identification tag includes informational data regarding the filter. A reader device supported on the frame and configured to receive the informational data from the identification tag. The filter information system records the informational data of the filter received in the filter tray holder.

Claims (28)

1. A filter reading system for a matte box for a camera, the filter reading system comprising:

a filter holder defining a plurality of stages each configured to receive a filter, the filter holder configured to be positioned in front of a camera lens, the filter holder including a reader device;

a filter tag configured to couple to the filter, the filter tag having filter information corresponding to the filter attached thereto; and

a display device coupled in communication with the reader device, the display device having a display screen, wherein when the filter with the filter tag is inserted into a stage of the plurality of stages, the reader device is configured to read the filter information of the filter and detect stage position of the filter, and display the filter information and the stage position on the display screen.

2. The filter reading system of claim 1 , wherein the filter holder includes a pair of sidewalls, the reader device disposed on one of the sidewalls.

3. The filter reading system of claim 1 , wherein the filter tag is a radio-frequency identification (RFID) tag, and wherein the reader device is a RFID reader device.

4. The filter reading system of claim 1 , further comprising a filter tray, the filter tray supporting the filter and configured to be at least partially received within the filter holder.

5. The filter reading system of claim 1 , wherein the display device is wirelessly coupled in communication with the reader device.

6. The filter reading system of claim 1 , wherein the display device is configured to couple in communication with a user device.

7. The filter reading system of claim 1 , wherein the display device is battery powered.

8. The filter reading system of claim 1 , wherein each stage of the plurality of stages includes an individual reader device.

9. The filter reading system of claim 1 , wherein the filter tag is a read/write tag.

10. The filter reading system of claim 1 , wherein the filter reading system is an upgrade kit configured to integrate with an existing matte box.

11. A method of capturing filter information within a matte box for a camera, the method comprising:

providing the matte box with a filter holder defining a plurality of stages in front of a camera lens;

providing a filter having a filter tag, wherein the filter tag has filter information corresponding to the filter attached thereto;

inserting the filter into one of the plurality of stages in the filter holder;

reading the filter information of the filter and detecting stage position of the filter inserted into the filter holder via a reader device supported within the filter holder; and

displaying, via a display device having a display screen coupled in communication with the reader device, the filter information and the stage position on the display screen.

12. The method of claim 11 , further comprising writing the filter information on the filter tag.

13. The method of claim 12 , wherein writing the filter information is performed using a user device coupled in communication to the display device.

14. The method of claim 11 , further comprising recording time information of the filter within the filter holder.

15. The method of claim 14 , wherein recording time information includes logging time or timecode.

16. The method of claim 11 , wherein reading the filter information and detecting stage position is performed by radio-frequency identification (RFID).

17. The method of claim 11 , wherein the filter is disposed within a filter tray, and inserting the filter into the filter holder includes at least partially inserting the filter tray within the filter holder.

18. The method of claim 11 , wherein the filter holder includes a pair of sidewalls, the reader device disposed on one of the sidewalls, and wherein each stage of the plurality of stages includes an individual reader device such that reading the filter information and detecting stage position is performed individually for each of the plurality of stages.

19. The method of claim 11 , further comprising mounting the display device on the matte box or the camera.

20. The method of claim 11 , further comprising upgrading an existing matte box with the filter holder having the reader device.
