Abstract

A system is disclosed which comprises a combination of a camera module with a host system for processing image data. The host system receives the image data as frame rate measuring information from the camera module and measures the frame rate with the use of the image data. The host system is so configured as to, if the measured frame rate is not fitted to a transfer rate specification of the system, control the camera module and adjust the frame rate of the image data.

Claims

1. An apparatus comprising:

a module body;

an interface mounted in the module body and configured to output image data to an external system; and

a controller configured to provide frame rate measuring information of the image data to the external system connected to the interface.

2. An apparatus according to claim 1, furthermore comprising a camera sensor configured to realize an image capturing function, wherein said controller includes a camera controller configured to control the camera sensor.

3. An apparatus according to claim 1, wherein the interface includes a connector removably mounted relative to the external system and a transfer controller configured to transfer the image data to the external system via the connector.

4. An apparatus according to claim 1, wherein the interface and said controller are integrated into a common chip and incorporated into the module body.

5. An apparatus according to claim 1, wherein said controller includes a memory related to a decision of the frame rate and configured to store camera configuration information which decides an operation specification of the digital camera function, and the external system is configured to refer to camera configuration information by gaining access to a memory via the interface.

6. An apparatus according to claim 1, wherein said controller includes a memory relating to a decision of the frame rate and configured to store a plurality of camera configuration information which decide an operation specification of the digital camera function, and the external system is configured to refer to the respective camera configuration information by gaining access to the memory via the interface.

7. An apparatus according to claim 1, wherein said controller is configured to provide, as the frame rate measuring information, frame identification information identifying the frame of the image data or image data with the frame identification information added thereto to the external system via the interface.

8. An apparatus according to claim 1, wherein said controller is configured to control a camera operation in accordance with the camera configuration information selectively set by the external system and transfer the frame rate measuring information to the external system via the interface.

9. An apparatus according to claim 1, wherein said controller includes a camera controller configured to control a camera operation in accordance with camera configuration information and the camera controller has an adjust function to realize a fine adjusting function of the frame rate included in the camera operation.

10. An apparatus according to claim 1, wherein the module body includes a frame memory configured to store the image data of a frame unit generated under the digital camera function.

11. A system for processing image data, comprising:

a camera module configured to output image data and store camera configuration information which decide an operation specification of a camera function, the camera configuration information being accessible so as to refer thereto;

an interface removably connected to the camera module and configured to transfer the camera configuration information from the camera module; and

a controller configured to selectively set a camera configuration information to the camera module through the interface, in accordance with the camera configuration information.

12. A system according to claim 11, wherein said controller decides whether or not the measured frame rate is fitted to a transfer rate specification of the system.

13. A system according to claim 11, wherein said controller decides whether or not the measured frame rate is fitted to a transfer rate specification of the system and, when a result of decision is not fitted, re-sets the camera configuration information and again performs the measurement operation of the frame rate.

14. A system according to claim 11, wherein said controller is configured to receive frame identification information of the image data transferred from the camera module, or image data with the frame identification information added thereto via the interface and measure the frame rate by using the frame identification information.

15. A system according to claim 11, wherein said controller includes a counting means configured to count the number of interruptions by a frame synchronizing signal transferred from the camera module and measures the frame rate based on the count value.

16. A system according to claim 11, wherein said controller counts the number of received data of a frame unit transferred from the camera module and, based on the count value, checks the received data for integrity.

17. A system according to claim 11, wherein said controller makes a comparison between the frame rate measured in the camera module and the measured frame rate and, based on the result of comparison, decides the frame rate for fitness.

18. A system according to claim 11, wherein the camera module has an adjust function to realize a fine adjustment function of the frame rate included in a camera operation and said controller adjusts the frame rate, under the adjust function, in accordance with an extent of the measured frame rate.

19. A method for receiving a image data which is transferred from a module operated in accordance with a configuration information, comprising:

a step of setting configuration information which relates to a decision of a frame rate of image data; and

a step of transferring the configuration information to an external system,

20. A method according to claim 19, further comprising a step of, based on a result of measurement of the frame rate, deciding whether or not the frame rate of the image data is fitted to the specification of the system.
