Problems solved by technology

[0004] However, in the background art, when judging the execution / interruption of autofocus control, the change of the subject generated from the shooting of the first frame to the shooting of the second frame is not taken into consideration.
Therefore, in the background art, there is a limit to photographing performance

Embodiment

[0042] refer to figure 2 , the digital camera 10 of this embodiment includes a focus lens 12 and an aperture mechanism 14 driven by drivers 18a and 18b, respectively. The optical image passing through the imaging field of view of the focus lens 12 and the aperture mechanism 14 is irradiated on the imaging surface of the imaging device 16 .

[0043] On the imaging surface, a plurality of light receiving elements (=pixels) are arranged two-dimensionally, and the imaging surface is covered with color filters (not shown) in a Bayer array of primary colors. The light receiving elements arranged on the imaging surface correspond one-to-one to the filter elements constituting the color filter, and the amount of charge generated by each light receiving element reflects the intensity of light corresponding to the color of R, G, or B.

[0044] After the power is turned on, the CPU 34 issues a command to the driver 18c to repeat the exposure operation and the charge readout operation i...

Abstract

The imaging device (16) has an imaging surface that captures a field of view for shooting and outputs an image of the field of view for shooting. The shutter button (36s) transitions between a non-operating state, a half-pressed state, and a fully-pressed state. If the shutter button (36s) transitions to a state different from the non-operation state, the CPU (34) calculates the brightness change amounts ΔY_ae and ΔY_af as parameters representing changes in the shooting field of view captured by the imaging surface, and according to the shifted shutter The state of the button (36s) is used to set the thresholds TH_ae and TH_af to different sizes. Strict AE processing is executed when the brightness change amount ΔY_ae exceeds the threshold TH_ae, and AF processing is executed when the brightness change amount ΔY_af exceeds the threshold TH_af. When the shutter button (36s) transitions to the full-pressed state, the CPU (34) records the captured field image output from the imaging device (16) on the recording medium (40). As a result, imaging performance is improved.

Description

technical field [0001] The present invention relates to an electronic camera, and more particularly, to an electronic camera that adjusts imaging conditions in response to key operations. Background technique [0002] An example of such a camera is disclosed in Patent Document 1. According to this background art, if the autofocus mode is set, the first shot is performed with autofocus. Among them, if the shutter button is fully pressed within a specified time (that is, a very short period of time) after the first shot is taken, the auto focus control will not be performed again, and the last (that is, the first shot) will be used directly. AF value to shoot. Thereby, it is possible to take an in-focus photograph without missing a shutter chance that occurs near the photographed subject after the photographing of the first photograph is completed. [0003] [Patent Document 1] JP Unexamined Publication No. 2006-98589 [0004] However, in the background art, when judging th...
