Abstract

There is disclosed an image processing apparatus in which a system control circuit (50) monitors the power source voltage when data write access to a recording medium (200) occurs, and cuts off power supply to an image display unit (28) when the power source voltage becomes smaller than a predetermined value L2, so as to reduce write errors of data to be written resulting from a power source voltage drop, a control method of the image processing apparatus, and a storage medium.

Claims

1. An image processing apparatus comprising:

recording means for recording given image data or data other than the image in a recording medium;

display means for displaying the image;

power supply means for supplying electric power to said display means;

judging means for judging, during a time when an image is confirmed in an image reproduction mode, if a power supply capacity of said power supply means becomes smaller than a predetermined first capacity;

control means for turning off said display means when a judging result of said judging means in relation to the first capacity is affirmative;

wherein, when said display means is turned off during the time the image is confirmed in the image reproduction mode, an indicating unit having a lower power consumption than the display means is turned on to indicate that a process is being executed and writing of data left to be stored is performed.

2. An apparatus according to claim 1, further comprising warning means for judging if the power supply capacity of said power supply means becomes smaller than second capacity larger than the first capacity, and producing a warning when a judging result is affirmative.

3. An apparatus according to claim 2, wherein said warning means is different from said display means for displaying the image.

4. An apparatus according to claim 1, wherein the power source is a battery.

5. An apparatus according to claim 1, wherein said recording means is a recording medium detachable from an apparatus main body.

6. An apparatus according to claim 1, further comprising output means for outputting the image data or the data other than the image to an external apparatus, and wherein said power supply control means controls a power supply capacity to said output means.

7. A method of controlling an image processing apparatus, comprising the steps of:

recording given image data or data other than the image in a recording medium;

displaying the image on a display device;

judging, during a time when an image is confirmed in an image reproduction mode, if a power supply capacity of electric power supplied to the display device becomes smaller than a predetermined first capacity;

controlling recording by turning off said display device when a judging result in said judging step in relation to the first capacity is affirmative; and

wherein, when the display device is turned off during the time the image is confirmed in the image reproduction mode, an indicating unit having a lower power consumption than the display device is turned on to indicate that a process is being executed and writing of data left to be stored is performed.

8. A method according to claim 7, further comprising a warning step of judging if the power supply capacity of the electric power supplied to the display device becomes smaller than second capacity larger than the first capacity, and producing a warning when a judging result is affirmative.

9. A method according to claim 8, wherein the warning step includes the step of displaying the warning other than on the display device for displaying the image.

10. A method according to claim 7, wherein the electric power supplied to the display device is supplied from a battery.

11. A method according to claim 7, wherein the recording medium is a recording medium detachable from an apparatus main body.

12. A method according to claim 7, wherein the power supply control step includes the step of controlling a power supply capacity to an output device for outputting the image data or the data other than the image to an external apparatus.

13. A storage medium computer readably storing a program for implementing a method of controlling an image processing apparatus of any one of claims 7 to 9 and 10 to 12.

14. An image processing apparatus comprising:

recording means for recording given image data or data other than the image in a recording medium;

displaying means for displaying the image data on a display device;

power supply means for supplying electric power to said image processing apparatus;

judging means for judging, during a time when an image is confirmed in an image reproduction mode, if a power supply capacity of said power supply means becomes smaller than a predetermined first capacity; and

control means for controlling turning off said display device when a judging result of said judging means in relation to the first capacity is affirmative; and

power supply control means for reducing the electric power to be supplied to said image processing apparatus while assuring electric power to be supplied to said recording means when the supply capacity of said power supply means becomes smaller than the predetermined first capacity,

wherein, when said power supply control means reduces the electric power to be supplied to said image processing apparatus, the display device is turned off and an indicating unit is turned on to indicate that a process is being executed, and

wherein power consumption of said indicating unit is lower than power consumption of said display device.

15. A method of controlling an image processing apparatus, comprising the steps of:

recording given image data or data other than the image in a recording medium;

displaying the image data on a display device;

judging, during a time when an image is confirmed in an image reproduction mode, if a supply capacity of electric power supplied to said image processing apparatus becomes smaller than a predetermined first capacity;

controlling by turning off said display device when a judging result in said judging step in relation to the first capacity is affirmative; and

reducing the electric power to be supplied to said image processing apparatus while assuring electric power to be supplied to said recording means when it is determined in the judging step that the supply capacity becomes smaller than the predetermined first capacity,

wherein, when the electric power to be supplied to said image processing apparatus is reduced in said reducing step, the display device is turned off and an indicating unit is turned on to indicate that a process is being executed, and

wherein power consumption of said indicating unit is lower than power consumption of said display device.

16. A storage medium computer readably storing a program for implementing a method of controlling an image processing apparatus of claim 15.
