camera device

Abstract

The present invention provides an imaging device capable of locally promoting or suppressing exposure of a subject image during long-time photography, capable of changing photography conditions after the start of photography, and capable of obtaining long-time images desired by the photographer. In the case of setting the shooting progress display mode (S7), after the exposure starts (S11), the image signal is read out every time the exposure time elapses, the cumulative addition image is synthesized (S21), and the cumulative addition image is displayed ( S27 ), if the photographer designates a specific area and performs an exposure setting change operation ( S29 ), execute exposure setting change processing for the specific area ( S31 ).

Description

technical field [0001] The present invention relates to an imaging device capable of displaying an image during exposure by repeatedly reading out image signals from an imaging element during an exposure operation and adding the read out image signals. Background technique [0002] Generally, when shooting subjects such as starry sky, fireworks, and night scenes, bulb photography is mostly used. In this bulb photography, the appropriate exposure time, that is, the time from when the shutter is opened to when the shutter is closed (exposure time), differs depending on the photographic subject and surrounding conditions, and the exposure time must be determined based on the photographer's own judgment. [0003] Therefore, if the photographer himself makes a mistake in judging the exposure time in advance, the photograph taken will become an underexposed or overexposed photograph. [0004] Therefore, when performing bulb photography or the like, it would be convenient for dete...

AI Technical Summary

Problems solved by technology

Therefore, the image desired by the photographer is a picture in which both the fireworks and the surrounding subjects are sufficiently bright, but it is sometimes difficult to achieve the long-time shooting of the image that is actually captured as the image desired by the photographer.

[0010] In addition, in the case of long-term exposure, it is difficult to set the shooting conditions such as aperture, ISO sensitivity, and image quality settings before shooting based on the following (1) and (2).

[0011] (1) In long-time photography, the subjects are mostly very dark, and it is difficult to set the shooting conditions

[0012] (2) Predicting the movement and brightness of main subjects such as fireworks, stars, fireflies, and car headlights requires experience and sense, and it is difficult for ordinary photographers to set shooting conditions
