5. The imaging device of claim 1 , wherein the image display section, after initial image display has been carried out, displays information based on the number of times of image update, superimposed on a display image.
6. The imaging device of claim 1 , wherein the image display section, immediately after commencement of the exposure operation, displays first information indicating that the exposure operation has commenced, instead of the added image, and at the time of displaying the added image, displays second information in order to notify that the exposure operation is ongoing, in a format that is different to the first information.
7. An imaging method for executing an exposure operation in response to an instruction signal, comprising:
repeatedly forming subject images in an imaging section in a set period, and outputting image data;
carrying out sequential addition processing of the output image data; and
executing processing for added image data, and displaying the newest added image in an image display section,
wherein the image display section, in order to notify that the exposure operation is ongoing, displays information based on a number of times images of the imaging section have been updated superimposed on the added image,
wherein the image display section, immediately after commencement of the exposure operation, displays information indicating that the exposure operation has commenced instead of the added image.
8. The imaging method of claim 7 , wherein the image display section, immediately after commencement of the exposure operation, displays information indicating that the exposure operation has commenced on a monochromatic background.
9. The imaging device of claim 7 , wherein the information is information corresponding to elapsed time of the exposure operation that has been calculated based on the number of times images of the imaging section have been updated.
10. The imaging device of claim 7 , wherein the image display section, once a brightness level of the added image data has reached a specified level, sequentially displays added image data after that.
11. The imaging device of claim 7 , wherein the image display section, after initial image display has been carried out, displays information based on the number of times of image update, superimposed on a display image.
12. The imaging device of claim 7 , wherein the image display section, immediately after commencement of the exposure operation, displays first information indicating that the exposure operation has commenced, instead of the added image, and at the time of displaying the added image, displays second information in order to notify that the exposure operation is ongoing, in a format that is different to the first information.
13. An imaging device, comprising:
an imaging section for repeatedly forming subject images in a set period while bulb exposure is being performed, and outputting image data;
an adding processing section for carrying out addition processing with previous image data each time the image data is output, to generate an added image;
an image display section for displaying the added image; and
a designation section for displaying first notification information indicating that bulb exposure is being performed, on the image display section, for a given period from commencement of the bulb exposure, instead of the added image, and, after a given period has elapsed after commencement of bulb exposure, displaying second notification information at a different position than the first notification information.
14. The imaging device of claim 13 , wherein the first notification information that is displayed for a given period from commencement of the bulb exposure is a notification using textual information.
15. The imaging device of claim 13 , wherein the second notification information that is displayed after a given period has elapsed from commencement of the bulb exposure is a notification using numerical information.
16. The imaging device of claim 13 , wherein the given period is a period until a brightness level of the added image reaches a specified level.
17. The imaging device of claim 13 , wherein the given period is a period until an elapsed time from commencement of bulb exposure reaches a specified value.
18. The imaging device of claim 13 , wherein after the given period has elapsed, the added image is displayed, and at the same time second notification information indicating that bulb exposure is in progress is displayed superimposed on part of the added image.
19. The imaging device of claim 13 , wherein the second notification information further displays an elapsed time from commencement of the bulb exposure.
