Problems solved by technology

Therefore, in the technique proposed in Japanese Patent Laid-Open No. 2015-144346, the time taken from the start of imaging (exposure) to display on the monitor becomes uneven due to the difference in resolution, which may give a sense of incongruity to the user
In addition, in the technology disclosed in Japanese Patent Laid-Open No. 2015-144346, the exposure timing of the still image and the exposure timing of the LV image are not taken into consideration, which leads to a change in the movement amount of the moving subject on the display screen when the subject is captured, and may cause discomfort to the user

[0040] Next, refer to Figure 2A and 2B The operation of the imaging apparatus 100 during continuous shooting in the first embodiment is described. Figure 2A is a timing chart in the case where the delay time between the exposure period of the LV image and the display start timing and the delay time between the exposure period of the still image and the display start timing are controlled to be the same, and shows the timing diagram for easy viewing with Figure 2B The differences in the controls shown. Figure 2B This is to control the delay time between the exposure period of the LV image and the display start timing to be the same as the delay time between the exposure period of the still image and the display start timing, and to control the intervals between the exposure periods to be equal. The timing diagram for the case.

[0061] Next, refer to Figure 5 , the flow in the case where continuous shooting of still images is performed while performing live view display in the second embodiment will be described. Note that the processing of steps S100 to S107 is the same as that referred to in the first embodiment Figure 4 The described processing is the same, so its description is omitted here.

[0062] After the live view display process is performed with the same aperture value and exposure value as those of the still image in step S107, it is determined in step S208 based on the subject tracking result of the subject tracking unit 110 that the subject from the image sensor 101 Area to be read (partial area). In step S209 , the CPU 103 reads the area determined in step S208 from the image sensor 101 without thinning out, and acquires an AF image. Since the LV image captured in the live view display process is read out from the image sensor 101 by reading pixels in every predetermined number of...

Abstract

The invention relates to an image capturing apparatus and a control method thereof, and a non-transitory storage medium. The image capturing apparatus comprising: an image sensor; a display; and a controller that controls exposure timing of the image sensor and display timing of displaying an image read from the image sensor in the display. The controller controls to continuously read first imagesand second images, resolution of the first images and resolution of the second images being different from each other, controls the exposure timing so that intervals between first reference times during exposure periods of the first images and second reference times during exposure periods of the second images are substantially equal, and controls the display timing so that time from the first reference time until the first image is displayed in the display and time from the second reference time until the second image to be displayed in the display are substantially equal.

Description

technical field [0001] The present invention relates to an imaging device, a control method thereof, and a non-transitory storage medium. Background technique [0002] Generally, an imaging apparatus such as a digital camera is provided with a so-called continuous shooting function for continuously acquiring still images. It is known that during continuous shooting, a live view (LV) image for live view and a still image for recording, which are different in type from each other, are read out, and the images are displayed in real time on a display such as a rear monitor provided in an imaging device. , and record still images in parallel. [0003] For example, there is known a technique for improving followability of a main subject at the time of focus detection by displaying an LV image acquired from an image sensor on a display device while performing focus detection during continuous shooting. Japanese Patent Laid-Open No. 2015-144346 proposes a technique of switching be...
