Embodiment Construction

[0034] The following examples describe the present invention in more detail.

[0035] combine figure 1 The device for superimposing artistic fonts on images based on FPGA of the present invention includes: artistic word conversion image module 1, image to be displayed 2, coe generation module 3, block RAM storage module A4, counter and control module 5, block RAM storage module B6 , a clock module 7, a superimposer 8, a parallel / serial conversion module 9, and an HDMI display 10.

[0036] The wordart-to-image conversion module 1 uses an online wordart generator to generate corresponding images after inputting information such as characters, fonts, sizes, word colors, and background colors. Wherein, the format of the generated image is JPEG, the size cannot exceed the size of the image to be displayed, and the background color can be set to any color other than the color used by the artistic word.

[0037] Described image to be displayed 2, the format is JPEG, and the size of...

Abstract

The invention provides a device and method for superimposing art fonts on an image based on an FPGA. The device comprises an art font-to-image module (1), a coe generation module (3), a block RAM module A (4), a counter and control module (5), a block RAM module B (6), a clock module (7), a superimposer (8), a parallel/serial conversion module (9) and an HDMI display (10). According to the deviceand the method, the technical problem that a display effect of superimposing characters is stiff when the image is displayed on the HDMI display by taking the FPGA as a master control chip in the prior art is solved. Through adoption of the device and the method, different art fonts can be superimposed when the image is displayed, increasingly developing demands in the field of digital video display are satisfied, and the user experience is improved.

Description

technical field [0001] The present invention relates to an FPGA digital image processing device and method, in particular to a device and method for superimposing artistic fonts on images. Background technique [0002] With the development of video technology, FPGA video processing technology has been widely used in many fields, such as aerospace, security monitoring and medical equipment. At present, when using FPGA as the main control chip to display images, if it is necessary to superimpose characters, such as displaying on schedule, camera name, specific logo, etc., usually a dedicated digital video character superimposition chip or FPGA's OSD (On Screen Display) IP core is used. [0003] Using the above two schemes, the superimposed characters are completely determined by the chip or IP core used, and are limited by cost and application occasions. Generally, there are only 10 Arabic numerals, 26 uppercase and lowercase English letters, and a small number of special sym...
