Image-capturing apparatus, image processing system, control method, and storage medium for use with external printer with determination of operating state of external printer and corresponding adjustment of clock signal
First Claim
1. An image-capturing apparatus having a function for printing a captured image with the use of an external printer, comprising:
- image-capturing means for obtaining the captured image;
control means for controlling the operation of the apparatus during an image-capturing processing and a printing processing;
clock generating means for operating the control means, the clock generating means generating clock signals having different frequencies, as between when the printing processing is executed and when the image-capturing means is executed; and
determining means for determining whether an operating state of the external printer is in a predetermined normal state for printing processing,wherein, in a case where the determining means determines that the external printer is in the normal state, the clock generating means changes a frequency to that of when the printing processing is executed.

Abstract
An image-capturing apparatus has a function for printing an image with the use of an external printer. The image-capturing apparatus includes an image-capturing section, a control section, and a clock generating section. The control section controls the operation of the entire image-capturing apparatus, including the image-capturing section (hardware), and executes printing processing for printing an image by the external printer. The clock generating section generates a higher operating frequency when the control section executes printing processing (i.e., in a printing mode) than when the image-capturing section obtains an image (i.e., in an image-capturing mode), for the control section.

1. An image-capturing apparatus having a function for printing a captured image with the use of an external printer, comprising:
-
image-capturing means for obtaining the captured image; control means for controlling the operation of the apparatus during an image-capturing processing and a printing processing; clock generating means for operating the control means, the clock generating means generating clock signals having different frequencies, as between when the printing processing is executed and when the image-capturing means is executed; and determining means for determining whether an operating state of the external printer is in a predetermined normal state for printing processing, wherein, in a case where the determining means determines that the external printer is in the normal state, the clock generating means changes a frequency to that of when the printing processing is executed. - View Dependent Claims (2, 3, 4)

5. An image-capturing apparatus having a function for printing a captured image with the use of an external printer, comprising:
-
image-capturing means for obtaining the captured image; mode switching means for switching between an image-capturing mode which is to execute the image-capturing processing by the image-capturing means and a printing mode which is to execute the printing processing; control means for controlling the operation of the apparatus, including the image-capturing processing and the printing processing; clock generating means for the control means, the clock generating means generating clock signals having different operating frequencies as between when the printing processing is executed and when the image-capturing processing is executed; and determining means for determining, after the mode switching means switches a mode to the printing mode, whether an operating state of the external printer is in a predetermined normal state for printing processing, wherein, in a case where the determining means determines that the external printer is in a normal state, the clock generating means changes a frequency to that of when the printing processing is executed. - View Dependent Claims (6, 7, 8)

9. A control method for an image-capturing apparatus having image-capturing means for obtaining a captured image, control means for controlling the operation of the image-capturing apparatus comprising at least the image-capturing means and for executing a printing processing, and a function for printing the captured image by an external printer, comprising:
-
a generating step of generating a clock signal having a predetermined frequency for the image-capturing means and for the control means; a determining step of determining whether an operating state of the external printer is in a predetermined normal state of printing processing; and a changing step of changing the frequency of the clock signal generated in the generating step to a frequency of when the printing process is executed in a case wherein it is determined in the determining step that the external printer is in the normal state. - View Dependent Claims (10, 11)

12. A control method for an image-capturing apparatus having image-capturing means for obtaining a captured image, control means for controlling the operation of the image-capturing apparatus comprising at least the image-capturing means and for executing a printing processing, comprising:
-
a determining step of determining whether the operation of the external printer is in the normal state for the printing processing or not, wherein a frequency of a clock signal supplied to the image-capturing means and to the control means is changed to that of when the printing processing is executed when the determining step determines that the external printer is in the normal state. - View Dependent Claims (13, 14)

15. A control method for an image-capturing apparatus having image-capturing means for obtaining a captured image, control means for an image-capturing processing by the image-capturing means and a printing processing, and a function for printing the captured image by an external printer, comprising:
-
a mode selecting step of selecting a mode between an image-capturing mode which is to execute the image-capturing processing and a printing mode which is to execute the printing processing; a generating step of generating a clock signal having a frequency for the control means according to the mode which is selected by the mode selecting step; a determining step of determining, after the mode is switched to the printing mode, whether an operating state of the external printer is in a predetermined normal state of printing processing, wherein, in a case wherein it is determined in the determining step that the external printer is in the normal state, the clock signal generated in the generating step is generated at a frequency of when the printing processing is executed, and wherein the generating step changes the frequency when the printing processing is terminated. - View Dependent Claims (16)
