Abstract

An image displaying apparatus includes a displaying section capable of performing a luminance adjustment, an image correcting section performing a luminance correction on each of a plurality of images at a time of a dynamic display continuously displaying the plurality of images on the displaying section at a constant interval, a luminance adjusting section performing a luminance adjustment at the displaying section displaying the images to which the luminance correction is performed based on the luminance correction at the image correcting section, and a display controlling section performing a control at the luminance adjusting section within a shorter period than the constant interval when switching from the dynamic display to a static display displaying an image different from the plurality of images.

Claims

1. An image displaying apparatus, comprising:

a displaying section comprising;

a liquid crystal panel for displaying a plurality of images; and

a backlight section for emitting light illuminating the liquid crystal panel;

a display controlling section performing a display control of the displaying section, wherein the display controlling section comprises;

an image correcting section performing a luminance correction on each of the plurality of images at a time of a dynamic display continuously displaying the plurality of images on the liquid crystal panel at a constant interval; and

a luminance adjusting section performing a luminance adjustment of the backlight section when displaying the images to which the luminance correction is performed based on the luminance correction at the image correcting section;

wherein the display controlling section

displays by once switching from the dynamic display to a blackout image when switching from the dynamic display to a static display displaying an image different from the plurality of images,

lowers a value of luminance in the displaying section to a zero percent value by steeply performing the luminance adjustment at the displaying section when displaying the blackout image on the displaying section, and

stops the luminance correction at the image correcting section during a period of displaying the blackout image on the displaying section and simultaneously switches from displaying the blackout image to the dynamic display after steeply changing the value of the luminance in the displaying section from the zero percent value to a value of luminance in the static display.

2. An imaging apparatus, comprising:

the image displaying apparatus according to claim 1; and

an image sensor capable of continuously acquiring the plurality of images at a constant interval.

3. The imaging apparatus according to claim 2, wherein

the dynamic display is made up of a display of one of a through image acquired by the image sensor before or after a release operation and a moving image acquired by the image sensor based on the release operation.

4. The imaging apparatus according to claim 2, wherein the static display is made up of a display of one of a still image acquired by the release operation and a set image used at a setting time.

5. The imaging apparatus according to claim 4, wherein

the still image includes a confirmation image of an imaging state.
