Embodiment 1
[0032] An embodiment of the present invention provides a method for playing pictures, specifically as Figure 5 shown, including:
[0033] S101. Obtain an original picture.
[0034] S102. Acquire the position of the center point of the main body area of the original image.
[0035] Specifically, the main body area of the original picture in this embodiment of the present invention refers to the highlighted area of the original picture. example, such as figure 1 The house d shown is the highlighted area of the original picture a, that is, the main area. Certainly, the above example is only an enumeration of the main body area of the original picture, and the highlighted area may be at any position in the original picture, which is not specifically limited in this embodiment of the present invention.
[0036] For example, the salient area extraction algorithm can be used to obtain the main body area of the original picture, and the center point of the main body a...
Embodiment 2
[0119] The embodiment of the present invention provides a device 1 for playing pictures, such as Figure 10 As shown, the device 1 includes: an acquisition unit 11 , a playback unit 12 , an amplification unit 13 , and a determination unit 14 .
[0120] Wherein, the acquiring unit 11 is configured to acquire the original picture and the central point position of the main body area of the original picture.
[0121] The playing unit 12 is used to play the original picture.
[0122] The enlargement unit 13 is configured to enlarge the original picture according to a preset magnification factor to obtain a first enlarged picture.
[0123] The determining unit 14 is configured to determine a display area centered on the central point of the subject area in the first enlarged picture, and obtain a second enlarged picture.
[0124] The playing unit 12 is also used to play the second enlarged picture.
[0125] Preferably, the embodiment of the present invention provides a device 1...

Abstract
The embodiment of the invention provides a picture playing method and device. According to existing picture playing techniques, when each picture is played, and when a salient display area of the picture is located at the edge of the picture, the salient display area of an enlarged picture cannot appear fully or cannot appear in a display area, while, with the method and device of the invention adopted, the above situation can be avoided. The method includes the following steps that: an original picture and the position of the central point of a main area of the original picture can be obtained; when the original picture is played, and the original picture is enlarged according to a preset enlargement factor, so that a first enlarged picture can be obtained; a display area which adopts the central point of the main area as a center is determined in the first enlarged picture, so that a second enlarged picture can be obtained; and the second enlarged picture is played. The picture playing method and device of the invention are applicable to the image processing field.
Description
technical field [0001] The invention relates to the field of image processing, in particular to a method and device for playing pictures. Background technique [0002] With the popularization of electronic equipment, the application of electronic equipment is more and more extensive. At present, many electronic devices in daily life have the function of playing pictures. The existing picture playing function can realize the automatic continuous playing of pictures, that is, the pictures in the photo album are automatically played one by one. Wherein, when each picture is played, the center point of the picture is fixed as the reference to gradually enlarge the picture before playing, so as to realize the dynamic effect of gradually enlarging each picture when playing. [0003] However, because the existing picture playback technology is fixed to gradually enlarge the picture based on the center point of the picture when playing each picture, that is, the center point of th...
