Portable image pickup device

Abstract

From a time point at which a storage capacity reaches a certain remaining capacity with respect to a limit value of 4 GB per one file depending on a file system, a subtraction time-managing portion (100A) changes photographing elapsed time display (174) which is displayed on a display picture of a liquid crystal display portion (17) to subtraction time display (178) in which residual time until 4 GB is reached is continuously subtracted in the inside of a portable image pickup device (1). Hence, a photographer can be visually informed of timing at which the photographing blank time period will occur. As a result, the photographer can be previously given the opportunity for the judgment about whether the photographing should be continuously performed or the current photographing should be ended to start new photographing.

Claims

1. A portable image pickup device, comprising: a recording portion for recording an image signal generated in accordance with a recording operation in a first file; anda subtraction time-managing portion for, when a ratio of an amount of data on the image signal recorded in the first file to a capacity per one file exceeds a given value, instructing a displaying portion to display a time in which the amount of data reaches the capacity.

2. A portable image pickup device according to claim 1, wherein: the subtraction time-managing portion instructs the display portion to display the time in a form different from a time elapsed in the recording operation.

3. A portable image pickup device according to claim 1, wherein: the subtraction time-managing portion instructs the display portion to display a time elapsed in the recording operation for a second file for which the recording operation is newly started, where the amount of data reaches the capacity of the first file.

4. A portable image pickup device according to claim 1, wherein: the recording portion records the image signal in the first file, the amount of data which is recordable in the first file depending on a file system of the recording portion.

5. A portable image pickup device, comprising: a recording portion for recording an image signal generated in accordance with a recording operation in a first file; anda subtraction time-managing portion for, when a ratio of an amount of data on the image signal determined from a bit rate based on a quality of photographed image recorded in the first file to a capacity per one file exceeds a given value, instructing a displaying portion to display a time in which the amount of data reaches the capacity.

6. A portable image pickup device according to claim 5, wherein: the subtraction time-managing portion instructs the display portion to perform the subtraction display the time in a form different from a time elapsed in the recording operation.

7. A portable image pickup device according to claim 5, wherein: the subtraction time-managing portion instructs the display portion to display a time elapsed in the recording operation for a second file for which the recording operation is newly started, where the amount of data reaches the capacity of the first file.

8. A portable image pickup device, comprising: a recording portion for recording an image signal generated in accordance with on a recording operation in a first file; anda subtraction time-managing portion for, when a ratio of an amount of data on the image signal determined from a bit rate based on a quality of photographed image recorded in the first file to a capacity per one file exceeds a given value, instructing a displaying portion to change display of a time elapsed in the recording operation to display of a time in which the amount of data reaches the capacity.

9. A portable image pickup device according to claim 8, wherein: the subtraction time-managing portion instructs the display portion to display the time in a form different from a time elapsed in the recording operation.

10. A portable image pickup device according to claim 8, wherein: the subtraction time-managing portion instructs the display portion to display a time elapsed in the recording operation for a second file for which recording operation is newly started, where the amount of data reaches the capacity of the first file.

11. A portable image pickup device, comprising: a memory portion including a first file, a second file and files subsequent to the first and second files;a recording portion for recording an image signal generated in accordance with a recording operation in the first file;a subtraction time-managing portion for calculating a residual capacity of the first file by subtracting the amount of data recorded in the first file from a capacity of the first file, and calculating a residual time of the recording operation for the first file by dividing the residual capacity by a bit rate in the recording operation; anda displaying portion for displaying the residual time.

12. A portable image pickup device according to claim 11, wherein: the subtraction time-managing portion instructs the displaying portion to display the residual time, when a ratio of the amount of data recorded in the first file to the capacity of the first file reaches a predetermined value.

13. A portable image pickup device according to claim 11, wherein: the subtraction time-managing portion instructs the displaying portion to display a time elapsed in the recording operation for the first file, before a ratio of the amount of data recorded in the first file to the capacity of the first file reaches the predetermined value.

14. A portable image pickup device according to claim 11, wherein: the subtraction time-managing portion instructs the display portion to display the time in a form different from a time elapsed in the recording operation.

15. A portable image pickup device according to claim 11, wherein: the subtraction time-managing portion instructs the display portion to display a time elapsed in the recording operation for a second file for which the recording operation is newly started, where the amount of data reaches the capacity of the first file.

16. A portable image pickup device according to claim 11, wherein: the recording portion records the image signal in the first file, the amount of data on which is recordable in the first file depending on a file system of the recording portion.
