Embodiment Construction

[0019] The display device for fast adaptive frame rate conversion proposed by the present invention: as figure 1 As shown, 101 is a video input control unit, line buffer unit 1 (RAM 1) 102 and line buffer unit 2 (RAM 1) 103 are line buffer storage, and the row buffer is stored in alternate storage mode through the window selection control unit 104, respectively. The row cache data in the cache unit 1 102 and the row cache unit 2 103 are filtered and adjusted to obtain row data of the same size. After this, the effective row data is delivered to FIFO1 (first-in-first-out) 105, when the amount of data in FIFO1 105 exceeds threshold a (threshold a can be customized according to the video image size, generally can be configured as one row of the input video image size ), send a write data request to the storage address calculation and management unit 106, after the storage address calculation and management unit 106 responds to the write data request, start data transmission and s...

Abstract

The invention relates to the field of image processing and display and aims at providing a rapid self-adaptive frame rate conversion display device. The device can meet the demands for multiple kinds of video input and display equipment and rapidly achieve a self-adaptive frame rate conversion function according to system requirements in a real-time video system, and is high in universality. Meanwhile, in the high-speed cache process of data, the device can effectively process data loss or overflow in a self-adaptive mode, so that data transmission precision is effectively improved. According to the structure of the rapid self-adaptive frame rate conversion device, a video input control unit stores the data into a first row cache unit and a second row cache unit in an alternate storage mode; a window selection control unit screens and adjusts the row cache data in the first row cache unit and the row cache data in the second row cache unit to obtain effective row data of the same size; later, the effective row data is transmitted into a first-in-first-out (FIFO) memory. The device is mainly applied to image processing and display occasions.

Description

technical field [0001] The invention relates to the field of image processing and display, and belongs to the category of buffer processing and display of real-time video. Specifically, it relates to a device and method for fast adaptive frame rate conversion. Background technique [0002] With the development of industrial application requirements, a variety of video image acquisition and display devices and various video formats emerge in an endless stream. Since they are not fully compatible with each other, different methods are required to convert them to each other. As an effective means, frame rate conversion can upgrade the video streams of different acquisition devices at different frame rates to meet the needs of various display devices, and it has attracted more and more attention. [0003] The frame rate improvement algorithm can be divided into two categories according to whether to perform motion estimation and corresponding motion compensation. The first ty...
