Problems solved by technology

[0012] However, the above-mentioned method not only needs to spend 5 cycle times of the vertical synchronous signal VD, but also takes a long CPU operation time Tcpu to arrange the entire frame data into a format that can be displayed on the display device
Moreover, a huge memory is required to completely read out the frame data, and the space of this memory will increase the area of ​​the hardware.
Therefore, to image 3 Arranging the horizontally divided frame data 30 into a format that can be displayed on a display device not only requires a huge computing time, but also requires a huge memory space

Abstract

The present invention proposes a device for arranging data with horizontal segmentation, including a frame memory and a frame data arrangement device. The frame data arrangement device is coupled with the frame memory. The frame memory is used to store frame data with m vertical fields, and each vertical field has n horizontal fields. The frame data arrangement device is used to cover the first data block by the arranged first data block and cover the second data block by the arranged second data block, wherein, the frame data of the first data block with Vstripe line are arranged according to the n values, and the frame data of the second data block with Hstripe line are arranged according to the m values.

Description

technical field [0001] The present invention relates to a data arrangement device and method, and in particular to a device and method for arranging data with horizontal division. Background technique [0002] With the progress of semiconductor and optoelectronic technology, more and more digital cameras, digital monitors or digital video cameras are flooding our lives. Photographic devices such as digital cameras, digital monitors, or digital video cameras require photosensitive elements to convert the sensed light signals into electrical signal outputs. Generally speaking, photosensitive elements are mostly charge coupled devices or complementary metal oxides. Semiconductor image sensing element (CMOS Image Sensor), and the image quality of CCD is better than that of the photography device of CMOS image sensing element. [0003] Please refer to figure 1 , figure 1 A schematic diagram of the format of image data generated by a conventional CCD is shown. as figure 1 As ...
