Abstract
The present invention includes an image processing apparatus having a slide show function of displaying a plurality of images while sequentially automatically switching the images and including an adding unit which adds a transition effect at the time of switching display from a first image to a second image, an obtaining unit which obtains characteristic values indicative of luminance of the first and second images, and a control unit which controls the adding unit to add a transition effect when the difference between the characteristic value of the first image and the characteristic value of the second image is equal to or larger than a predetermined threshold.
Claims12
An image processing apparatus having a slide show function of displaying a plurality of images on a display unit while sequentially automatically switching the images, comprising:
- an adding unit, at the time of switching display from a first image being displayed on the display unit to a second image to be displayed next to the first image, of adding a transition effect so that the second image is displayed gradually from the first image being displayed;
- an obtaining unit which obtains characteristic values indicative of luminance of the first and second images displayed on the display unit;
- and
- a control unit which controls the adding unit so that, when the difference between the characteristic value of the first image and the characteristic value of the second image obtained by the obtaining unit is equal to or larger than a predetermined transition effect threshold, the transition effect that the second image is displayed gradually from the first image is added at the time of switching display from the first image to the second image.
A method for controlling an image processing apparatus having a slide show function of displaying a plurality of images on a display unit while sequentially automatically switching the images, comprising:
- an adding step, at the time of switching display from a first image being displayed on the display unit to a second image to be displayed next to the first image, of adding a transition effect so that the second image is displayed gradually from the first image being displayed;
- an obtaining step of obtaining characteristic values indicative of luminance of the first and second images displayed on the display unit;
- and
- a control step of controlling the adding step so that, when the difference between the characteristic value of the first image and the characteristic value of the second image obtained in the obtaining step is equal to or larger than a predetermined transition effect threshold, the transition effect that the second image is displayed gradually from the first image is added at the time of switching display from the first image to the second image.
