Embodiment 1
[0028] see figure 1 , is a schematicflow chart of an embodiment of a video image processing method of the present invention, including steps:
[0029] Step S101: Acquiring the image resolution and allocating the first row of storage area;
[0030] Step S102: receiving data, storing the data in the current row storage area, and counting the data;
[0031] Step S103: Determine whether the number of counts is equal to the number of pixels on the horizontal axis of the image resolution, if so, enter step S104, if not, return to step S102;
[0032] Step S104: Determine whether the number of stored data rows is equal to the preset row, if yes, go to step S106, if not, go to step S105;
[0033] Step S105: allocate the next row of storage area, clear the count, and return to step S102;
[0034] Step S106: receiving a new data;
[0035] Step S107: When fetching data for the first time, allocate the first column storage area, fetch the data of the column where the earliest received...
Embodiment 2
[0087] see figure 2 , is a schematic structural diagram of the video image processing device of the present invention, including a generation module 201, and the generation module 201 includes:
[0088] Acquisition module 2011, for obtaining image resolution;
[0089] The receiving module 2012 is configured to receive data from the frame header of a frame of data;
[0090] The allocating storage module 2013 is used to store data in the current row storage area according to the row storage instruction of the first judging module, allocate the next row storage area according to the row storage instruction of the second judging module, and store the data in the next row storage area, According to the column storage instruction of the third judging module, when the number is fetched for the first time, the first column storage area is allocated, and the data of the column where the earliest received data is located in the row storage area is fetched from each row, and the data i...

Abstract
A method of video imageprocessing method comprises the following steps: acquiring an image resolution ratio and distributing row storage areas; receiving data, storing the data into a current row storage area and counting the data; judging whether the number of the counting is equal to that of pixels of the horizontal axis of the image resolution ratio or not and proceeding to receive the data if the number of the counting is not equal to that of the pixels of the horizontal axis of the image resolution ratio until the number of the counting is equal to that of the pixels of the horizontal axis of the image resolution ratio; judging whether the row number of data storage is equal to that of preset rows or not, distributing next row of storage area if the row number of the data storage is not equal to that of the preset rows, clearing the counting and keeping on receiving the data until the row number of the data storage is equal to that of the preset rows; receiving a new data; distributing column storage areas, taking one data once time from each row and storing the data into the column storage areas according to the sequence of receiving; judging whether the column number of the data storage is equal to that of the preset columns or not, keeping on taking the data from each row if the column number of the data storage is not equal to that of the preset columns and determining a pixel reference matrix if the column number of the data storage is equal to that of the preset columns. A corresponding device is provided and the data is separately stored in different storage areas according to the rows and the columns, the pixel reference matrix is generated, processing speed is improved and operation is simpler.
Description
technical field [0001] The invention relates to the field of image processing, in particular to a video imageprocessing method and device. Background technique [0002] Image processing, the technique of analyzing an image with a computer to achieve a desired result. Also known as image processing. Basic content image processing generally refers to digital image processing. A digital image refers to a large two-dimensional array obtained by sampling and digitizing with digital cameras, scanners and other equipment. The elements of the array are called pixels, and their values are an integer, called gray values. The main content of image processing technology includes three parts: image compression, enhancement and restoration, matching, description and recognition. Common processing includes image digitization, image coding, image enhancement, image restoration, image segmentation, and image analysis. Image processing generally refers to digital image processing. Vid...
