Abstract

Even if the digital camera is inexpensive without the function of reproducing images, it can effectively use a memory capacity and has the function of responding to quick image-capturing, and important images can be recorded with higher priority. The digital camera comprises a priority selection switch for selecting priority of an image, and information about selected priority is recorded in association with the image when the image is recorded. For example, priority is ranked on three stages of “important”, “normal”, and “memo”. When a recording medium for storing image data has an insufficient memory capacity, control is exercised such that an image with priority lower than a newly captured image is automatically erased to record the new image. Further, a recorded image may be analyzed to automatically assign a low priority value to an image that may be damaged.

Claims

1. A digital camera capable of recording in a recording medium an image captured through an image pickup element, the digital camera comprising:

a priority setting device which sets priority of a captured image; and

a recording device which records information indicative of the priority set by the priority setting device in association with the captured image when the captured image is recorded.

2. The digital camera according to claim 1, further comprising a frame number automatic correcting device which assigns frame numbers in order of priority by using the information indicative of the priority.

3. The digital camera according to claim 1, further comprising a control device which, if the recording medium has an insufficient recording capacity when a new image is captured, erases an image recorded in the recording medium with priority lower than the new image and records the new image in the recording medium.

4. The digital camera according to claim 3, further comprising a frame number automatic correcting device which assigns frame numbers in order of priority by using the information indicative of the priority.

5. The digital camera according to claim 1, wherein the priority setting device allows a user to select priority.

6. The digital camera according to claim 5, further comprising a frame number automatic correcting device which assigns frame numbers in order of priority by using the information indicative of the priority.

7. The digital camera according to claim 5, further comprising a control device which, if the recording medium has an insufficient recording capacity when a new image is captured, erases an image recorded in the recording medium with priority lower than the new image and records the new image in the recording medium.

8. The digital camera according to claim 7, further comprising a frame number automatic correcting device which assigns frame numbers in order of priority by using the information indicative of the priority.

9. The digital camera according to claim 1, wherein the priority setting device analyzes the captured image to determine whether the captured image is damaged or not and automatically sets lower priority than a normal image to a probably-damaged image.

10. The digital camera according to claim 9, further comprising a frame number automatic correcting device which assigns frame numbers in order of priority by using the information indicative of the priority.

11. The digital camera according to claim 9, further comprising a control device which, if the recording medium has an insufficient recording capacity when a new image is captured, erases an image recorded in the recording medium with priority lower than the new image and records the new image in the recording medium.

12. The digital camera according to claim 11, further comprising a frame number automatic correcting device which assigns frame numbers in order of priority by using the information indicative of the priority.

14. The digital camera according to claim 13, further comprising a control device which, if the recording medium has an insufficient recording capacity when a new image is captured, erases an image recorded in the recording medium with the identification information and records the new image in the recording medium.

13. A digital camera capable of recording in a recording medium an image captured through an image pickup element, the digital camera comprising:

a device which analyzes a captured image to determine whether the captured image is damaged or not and assigns identification information to a probably-damaged image; and

a recording device which records the identification information in association with the captured image when the captured image is recorded.
