High speed image selecting method and digital camera having high speed image selecting function

Abstract

In a digital camera operation method, photographic images are taken with the camera and a corresponding compressed high resolution image and also a corresponding lower resolution image is stored for each. A fast display mode of the camera sequentially displays individual lower resolution display images, using the data of one of the lower resolution images. A normal display mode displays high resolution display images by expanding and displaying one of the compressed high resolution images. When changing from the fast display mode to the normal display mode, the lower resolution display image currently displayed can be replaced with the corresponding high resolution display image.

What is claimed is: 
     
         1 . An apparatus comprising:
 a user instruction receiver configured to receive a first user instruction and a second user instruction;   a display unit:
 configured to display a first screen for displaying a low resolution image; 
 when the user instruction receiver receives the first user instruction, configured to change the low resolution image on the first screen; and 
 when the user instruction receiver receives the second user instruction, configured to select a low resolution image on the first screen and to change from the first screen to a second screen for displaying a high resolution image corresponding to the selected low resolution image; and 
   a controller configured to, after changing to the second screen, execute a preparation process to transmit image data corresponding to the high resolution image on the second screen via a wireless line.   
     
     
         2 . The apparatus according to  claim 1 , wherein after executing the preparation process, the image data can be transmitted via the wireless line. 
     
     
         3 . The apparatus according to  claim 1 , wherein the display unit is configured to change the low resolution image on the first screen by a scrolling operation which corresponds to the first user instruction. 
     
     
         4 . The apparatus according to  claim 1 , wherein the display unit is configured to change the low resolution image, one by one, on the first screen by a scrolling operation which corresponds to the first user instruction. 
     
     
         5 . The apparatus according to  claim 1 , wherein the display unit is configured to display the first screen for displaying the low resolution image without displaying the high resolution image, and
 wherein the display unit is configured to display the second screen for displaying the high resolution image without displaying the low resolution image.   
     
     
         6 . The apparatus according to  claim 1 , wherein a pixel number of the low resolution image is smaller than a pixel number of the high resolution image. 
     
     
         7 . The apparatus according to  claim 1 , further comprising:
 an imaging element configured to produce the image data based on imaging light,   wherein the low resolution image and the high resolution image are produced based on the image data.   
     
     
         8 . A method of displaying an image and transmitting data, the method comprising:
 displaying a first screen for displaying a low resolution image;   when receiving the first user instruction, changing the low resolution image on the first screen;   when receiving the second user instruction, selecting a low resolution image on the first screen and changing from the first screen to a second screen for displaying a high resolution image corresponding to the selected low resolution image; and   after changing to the second screen, executing a preparation process to transmit image data corresponding to the high resolution image on the second screen via a wireless line.
