Electronic camera apparatus

Abstract

An electronic camera device according to the first aspect of the present invention comprises a battery which supplies a power supply, a detector which detects a state of the power supply of the loaded battery, a flash device configured to illuminate a subject, a charge controller which controls a charge processing of charging an energy supplied to the flash device, a processing part which executes at least one processing requiring an electric power more than a predetermined value except a charge processing, and a part configured to execute the charge processing and at least one processing each unit of a predetermined processing by timesharing while keeping the electric power supplied by the battery to maximum.

1 . An electronic camera device comprising: 
 a battery which supplies a power supply;    a detector which detects a state of a power supply of the loaded battery;    a driver which drives a lens;    an imager which images a subject;    an image processing part which processes an image data obtained with the imager when a predetermined period is one cycle and whose processing speed is variable;    a display which displays the data obtained by the image processing part;    a flash device which illuminates the subject;    a charge controller which controls charge of an energy supplied to the flash device; and    a setting part which performs at least one of processing of the image data by the image processing part and driving of the lens by the driver and the charge control by the charge controller by timesharing, when the data displayed at charging for a predetermined number of cycles, and sets at least one of a processing speed of the image processing part and driving speed of the driver is set according to the usable maximum electric power of the battery.    
   
   
       2 . The electronic camera device according to  claim 1 , wherein the setting part sets either a processing speed of the image processing part or a driving speed of the lens by the driver in maximum.  
   
   
       3 . The electronic camera device according to  claim 1 , wherein the charge control by the charge controller is performed over a whole cycle without the image processing by the image processing part in a predetermined cycle following the second cycle when the same image data is repeatedly displayed on the display over two or more cycles.  
   
   
       4 . The electronic camera device according to  claim 1 , further comprising a selector which selects and switches whether the processing of image data by the image processing part and the charge control by the charge controller are performed by timesharing or not.  
   
   
       5 . The electronic camera device according to  claim 1 , wherein 
 the image processing part comprises a first image processing part to convert the image signal obtained in the imager into image data which can be memorized to the frame memory and a second image processing part to convert the image data memorized in the memory into the data which can be displayed on the display, and    the setting part sets a processing speed of the image processing by the second image processing part according to the usable maximum electric power of the battery.    
   
   
       6 . An electronic camera device comprising: 
 an imager which images a subject;    an image processing part which processes the image data obtained by the imager at a predetermined cycle;    a display which displays the data obtained by the image processing part;    a flash device which illuminates the subject;    a charge controller which controls a charge of the energy supplied to the flash device;    a display controller which controls data displayed on the display to update display every cycles of one cycle or two or more cycles; and    a setting part which performs processing of the image data by the image processing part and the charge control by the charge controller at the same time and sets the processing speed by the image processing part according to the usable maximum electric power of the battery to match to the cycle when the data displayed by the display is updated.    
   
   
       7 . The electronic camera device according to  claim 6 , wherein 
 the image processing part comprises a first image processing part to convert the image signal obtained in the imager into image data which can be memorized to the frame memory and a second image processing part to convert the image data memorized in the memory into the data which can be displayed on the display, and    the setting part sets a processing speed of the image processing by the second processing image part according to the usable maximum electric power of the battery.    
   
   
       8 . An electronic camera device comprising: 
 a flash device which illuminates a subject;    an imager which images the subject;    a display which displays an image data obtained by an imager as a visible image;    a display controller which can vary a refresh rate by a display;    a charge controller which can select an operation whether to charge the flash device when the display by the display is not carried out or to charge the said flash apparatus when the display is carried out by the display; and    a changer which changes the refresh rate by the display controller based on a selection result of the charge operation by the charge controller.    
   
   
       9 . The electronic camera device according to  claim 8 , further comprising a controller which controls the display to lower the refresh rate when the display by the display is performed at a charge of the flash device to illuminate the subject.
