Embodiment Construction

[0015] Next, an example in which the present invention is applied to a digital camera as one embodiment will be described. This digital camera has an imaging unit that converts a subject image into image data, and displays the subject image in a live view on a display unit arranged on the back of a main body based on the converted image data. The photographer decides the composition and shooting timing by observing the live view display. When a video button or the like is operated, recording of video image data starts, and when a video button or the like is operated again, recording of video image data ends. Furthermore, by operating the release button, it is also possible to capture a still image. When the reproduction mode is selected, image data of still images or moving images recorded on the recording medium can be reproduced and displayed on the display unit.

[0016] Also, in the camera of this embodiment, after changing the opening amount of the diaphragm and adjusti...

Abstract

Provided are an imaging device and an imaging method that do not generate flicker in an image even when the aperture value is changed. When the brightness of the subject changes and the aperture value of the aperture is changed in order to maintain an appropriate exposure, after the aperture is driven to change the aperture and the exposure is adjusted (time T1~T2), according to the change in the aperture of the aperture, by zooming in The amplification ratio of the pixel signal in the unit or the electronic shutter speed setting unit changes the electronic shutter speed to adjust the exposure amount (timing T2 to T4).

Description

technical field [0001] The present invention relates to an imaging device and an imaging method capable of performing exposure control to achieve an appropriate exposure even when the aperture value is changed during video capture or live view display. Background technique [0002] In an imaging device such as a camera, an electronic shutter speed and ISO sensitivity are simultaneously adjusted when the aperture is driven during movie shooting or live view display, thereby maintaining an appropriate exposure. However, since the aperture is mechanically driven, there is a delay in movement, whereas the electronic shutter speed and ISO sensitivity are controlled electrically, so there is almost no time delay in changing operations. Therefore, a time lag occurs until the desired exposure is reached, flickering occurs in a moving image or an image displayed in a live view, and the screen becomes difficult to observe. [0003] Therefore, an imaging device has been proposed that ...
