Description of the Invention: [Technical Field] The present invention relates to an image processor and related system for a field sequential three-dimensional display system, and more particularly to a field sequential three-dimensional display system without using a map A frame buffer for image conversion of image processors and related systems. [Prior Art] Three-dimensional (3D) display technology provides a more sleek visual experience than traditional two-dimensional (2D) display technology. In general, stereoscopic image processing involves at least two image systems, the image or film of which can be taken by two slightly different angles and positions, and then alternately output to the left and right eyes, the purpose of which is to simulate the position and angle of the human eye. The difference in k is perceived by the difference in ice. In a frame sequentiai two-dimensional display system, the two images are typically presented to the viewer via shutter glasses, respectively. The shutter glasses can use the electronically controlled liquid crystal material to make the left and right glasses, and the opening times of the left and right glasses are respectively synchronized with the display intervals of the left and right eye images, so that the viewer sees only the left eye. The left eye image 'the right eye only sees the right eye image, which allows the viewer to feel the depth illusion similar to real vision. Most display devices (such as televisions) have a scan frequency of 6 () Hz (for example, in the United States) or 50 Hz (for example, outside the United States - some other countries in the same two-dimensional mode 201230765, %-sequence TV Every 5G or 6G seconds will update the screen to see the daring, and the face of the TV will be reduced to -half. Therefore, the field Tr dimension display line needs to be 5_ _ Initially: the dimension image signal is multiplied by ^ to provide the multiplied two-dimensional image signal of the blue (3) system, and then the data extracted from each frame of the double frequency binary image signal is sequentially extracted, thereby providing the corresponding left The three-dimensional image signal of the eyelid surface and the right eye surface - just (10)_. The first figure is a functional block diagram of the prior art one-dimensional three-dimensional display system 100. The field sequential three-dimensional display system includes - the image source nG, An image processor 120, a sequence display device 130, and shutter glasses 140. The image source 1A can provide an initial two-dimensional image signal S1, which includes a plurality of frames representing a picture. The image processor 12 includes a frame frequency converter 22, a picture a buffer 24, and a two-dimensional/three-dimensional converter 26. The frame frequency converter 22 can insert a new frame between two adjacent parallel frames of the initial two-dimensional image signal S1, thereby generating a higher frame frequency. Corresponding to the multiplied two-dimensional image signal S2. According to the multi-frequency two-dimensional image signal S2, the two-dimensional/three-dimensional converter 26 can generate a three-dimensional image signal S3 comprising two series of sequence frames, wherein the two series of sequence frames respectively correspond to According to the 3D image signal S3, the field sequential display device 13 can alternately display the left eye image and the right eye image, and then control the shutter glasses 14〇 so that the viewer sees only the left eye. The left eye image, while the right eye only sees the right eye image. 201230765 Fig. 2 is a schematic diagram of the prior art image processor 120. It is assumed that the initial 2D image signal S1 is composed of a series of odd frames Fi~Ftsm and A series of even frames F2~FN are shown (N is an even number), and the two series of frames are related to the image to be displayed by the field sequential display device 130. The prior art three-dimensional display system 100 requires the use of the frame buffer 2 4, the frame Fi~FN received in the corresponding period is stored. In this way, the frame frequency converter 22 can output each frame in the frames Fi~FN twice. As shown in Fig. 2, The multi-frequency two-dimensional video signal S2 includes twice the number of frames, F!, F2, F2, ..., FN and FN. According to each pair of frames in the double-frequency two-dimensional video signal S2, the two-dimensional/three-dimensional converter 26 The double-frequency two-dimensional image signal S2 can be converted into a corresponding three-dimensional image signal S3, which includes the left-eye image Ι^~:ίΝ and the right-eye image heart~!^. The opening and closing of the shutter glasses 140 are opened by the left eye. The signal and the right eye turn on the signal to control. There is usually a time difference between the input and output frame data, and the initial 2D image signal S2 needs to be multiplied. Therefore, the prior art requires the use of the frame buffer 24 to store the data of each frame for a period of time so that the image processor 120 can output the correct data, but the frame buffer 24 increases the production cost.
