Embodiment Construction

[0019] A method and device for loading and displaying pictures provided by the present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0020] like figure 1 As shown, the embodiment of the present invention provides a method for loading and displaying pictures, and its specific implementation is as follows:

[0021] Step 110: Calculate the color range of the picture to be displayed.

[0022] Wherein, the color range reflects the degree of color change of the picture, and the greater the color range, the greater the degree of color change.

[0023] Step 120: According to the preset corresponding relationship between the color range and the image loading method, select the image loading method corresponding to the calculated color range, wherein, in the preset corresponding relationship between the color range and the image loading method, the color range The larger the value, the larger the number of color bits co...

Abstract

The invention discloses a picture loading display method and a device. The method comprises steps of calculating color amplitude of a to-be-displayed picture; and selecting a picture loading method corresponding to the obtained color amplitude according to the corresponding relation between the preset color amplitude and the picture loading method. In the corresponding relation, the bigger the color amplitude is, the bigger the color bit number of the corresponding loading method is. By using the selected loading method to load the to-be-displayed picture, display of the to-be-displayed picture is achieved, color of the displayed picture is not liable to distort, and a problem of low running efficiency caused by small color change and great memory expense is avoided.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method and device for loading and displaying images. Background technique [0002] In smart devices, many media resources are presented in the form of thumbnails. At present, for the color display of thumbnails, a picture loading method with a fixed number of bits is usually used to load the picture to be displayed to realize the display of the picture to be displayed, such as the commonly used Red Green Blue (RGB)_565, this processing way, the color information that can be represented is fixed. For pictures with rich colors and large changes, the image loading method with a fixed number of bits can represent less color information than the actual color information required, and the displayed pictures are prone to color distortion; for pictures with small color changes Generally speaking, the image loading method with a fixed number of bits can represent more...
