Arbitrary picture component generation method based on FPGA

Abstract

The invention discloses an FPGA (Field Programmable Gate Array)-based arbitrary picture component generation method, which comprises the following steps of: S1, configuring a color matching table in an image signal generator according to current picture information, each index of the color matching table being respectively composed of a number combination formed by orderly arranging a first numberand a second number, wherein the first number is a row serial number of any row of pixel points in the current picture information range, and the second number is a column serial number of any columnof pixel points in the current picture information range; and S2, scanning pixel points in the current picture information range, obtaining horizontal coordinate values and vertical coordinate valuesof the scanned pixel points, searching the color matching table based on a digital combination formed by the horizontal coordinate values and the vertical coordinate values, and setting color valuesof the pixel points as color values obtained by searching. According to the technical scheme, any picture image can be generated based on parameter configuration adjusted by a user.

Description

technical field [0001] The invention relates to the technical field of liquid crystal module testing, in particular to an FPGA-based method for generating arbitrary screen components. Background technique [0002] With the increasing popularity of home theaters, large-screen, high-resolution liquid crystal displays have gradually become the mainstream. In the process of producing liquid crystal displays, they need to be detected by a picture signal generator. [0003] Traditional picture signal generators use bmp images as image sources. When testing large-screen and high-resolution liquid crystal displays, the corresponding bmp image data is large, which requires high hardware requirements for the signal generator, resulting in unsmooth pictures during the detection process. The phenomenon. Under the premise of not increasing the hardware cost, FPGA (based on the hardware structure of FPGA to generate picture data such as figure 1 As shown, it includes a human-computer ...
