Embodiment 1

[0051] Embodiment 1 provides an image pixel value model for an automobile instrument,

[0052] f(i+u,j+v)=(1-u)(1-v)f(i,j)+u(1-v)f(i+1,j)+(1-u)vf( i,j+1)+uvf(i+1,j+1);

[0053]Among them, f(i+u,j+v) is the pixel value corresponding to the corresponding position (i+u,j+v) in the original image of a pixel in the enlarged image in the original image; (i,j) is the original image The nearest intersection point along the negative direction of the X-axis and the negative direction of the Y-axis, f(i,j) is the pixel value of the point; (i+1,j) is the positive direction of the original image along the positive direction of the X-axis and the negative direction of the Y-axis The nearest intersection point on , f(i+1,j) is the pixel value of the point; (i,j+1) is the nearest intersection point along the negative direction of the X axis and the positive direction of the Y axis in the original image, f(i,j +1) is the pixel value of the point; (i+1, j+1) is the nearest intersection point ...

Embodiment 2

[0055] figure 1 It is a flow chart of the high resolution image display method for automobile instrument related to the present invention.

[0056] like figure 1 As shown, on the basis of embodiment 1, this embodiment 2 also provides a high-resolution display method for an image of an automobile instrument, including: obtaining the position of each pixel in the enlarged image; obtaining the position of each pixel in the original image; according to The magnification factor obtains the position of each pixel point of the enlarged image in the original image; obtains the pixel value of each pixel point position of the enlarged image in the original image according to the image pixel value model; and high-resolution zoom-in according to the pixel value of each pixel point position of the enlarged image in the original image The original image is displayed, and the low-resolution image is enlarged and then displayed in high resolution, which reduces the performance requirements o...

Embodiment 3

[0075] Figure 4 It is a principle block diagram of the image high-resolution display system for the automobile instrument involved in the present invention.

[0076] like Figure 4 As shown, on the basis of Embodiment 2, this Embodiment 3 also provides a high-resolution image display system for automotive instrumentation, including: an enlarged image acquisition module to obtain the position of each pixel in the enlarged image; the original image acquisition module, Obtain the position of each pixel in the original image; the pixel corresponding module obtains the position of each pixel of the enlarged image in the original image according to the magnification; the pixel value acquisition module obtains the pixel of each pixel position of the enlarged image in the original image according to the image pixel value model value; and a high-resolution display module, which enlarges and displays the original image at high resolution according to the pixel value of each pixel posi...

Abstract

The invention belongs to the technical field of automobile instrument image display, and particularly relates to an image pixel value model, a high-resolution display method and system and an automobile instrument. The high-resolution display method comprises the steps: obtaining the position of each pixel point in an amplified image; obtaining the position of each pixel point in the original image; obtaining the position of each pixel point of the magnified image in the original image according to the magnification times; according to an image pixel value model, obtaining a pixel value of the amplified image at each pixel point position in the original image; and amplifying and displaying the original image at high resolution according to the pixel value of the amplified image at each pixel point position in the original image, so that high-resolution display after the low-resolution image is amplified is realized, the performance requirement on a main control chip is reduced, and the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of automobile instrument image display, and in particular relates to an image pixel value model, a high-resolution display method, a system and an automobile instrument. Background technique [0002] At present, the display screen driven by the automobile instrument is getting bigger and bigger, but the required image display master chip is also getting higher and higher, and the cost is also higher. The low-cost image display main control chip outputs low-resolution images, which cannot be enlarged and displayed with high resolution. [0003] Therefore, based on the above technical problems, it is necessary to design a new image pixel value model, high-resolution display method, system and automotive instrument. Contents of the invention [0004] The object of the present invention is to provide an image pixel value model, a high-resolution display method, a system and an automobile instrument. [0005]...
