Embodiment Construction

[0043] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the following will clearly and completely describe the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention. Apparently, the described embodiments are some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention belong to the protection scope of the present invention.

[0044] Since the FPGA's real-time pipeline operation for images is based on row units, the FPGA can be directly connected to the image sensor chip to obtain the image data stream, and if it is in RAW format, it can also perform difference to obtain RGB data. Its internal Block Ram can cache several lines of image data, which is also the key point for FPGA to perform real-time pipeline proce...

Abstract

The invention provides an image processing chip, method and equipment, a block RAM (Random Access Memory) in an FPGA (Field Programmable Gate Array) is used for replacing a memory, a CPU (Central Processing Unit) arithmetic unit processing part is transplanted into the FPGA, primary linear interpolation calculation is carried out on an image in the horizontal direction and the vertical direction respectively, a color channel numerical value of a target point is obtained, and a floating point coordinate is further obtained; and calculating according to the floating point coordinates to obtain an incidence relation between the original image coordinates and the target image coordinates, and zooming the image according to the incidence relation. The technical problem of image edge blurring is solved, the image processing speed and the zooming effect are improved, the real-time performance is achieved, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of electronic data signal processing, in particular to an image processing chip, method and equipment. Background technique [0002] In the prior art, the image scaling method usually performs bilinear interpolation algorithm operation in the CPU, and caches the processed image in SDRAM. The image processing structure diagram of the method with the CPU as the core is shown in the attached figure 1 shown. [0003] Although the method of the prior art has a high main frequency of the CPU, it is a general-purpose processor, and the main frequency of the CPU is after the pipeline is added, and does not have real-time image processing, and it needs multiple clock cycles to produce results, and It is not suitable for some computing-intensive task scenarios, and it is not suitable for some application fields with very high real-time requirements. The FPGA can perform real-time pipeline operations and achieve the ...
