Hi all,
Is there anybody suggest me how to display jpeg images from the SD card to 10.4" TFT LCD driven by my 8-bit microcontroller?
I done the SD Interface and also the LCD interface using SSD1963 controller, its working well and also I tried with the BMP images by reading the BMP header and display the direct RGB value to my LCD and displayed the images of resolution 640X480. Now I'm in a state of reading the JPEG header, I got the header information and DQT,DHT tables also, what I need is:
1. How to process the Huffman table (there are 4 tables, 2 for DC and 2 for AC)
2. How can the DQT table values used to process the DHT table.
3. How can i get the Y,Cb,Cr values from the scan data.:?:
I go throughed all the possible documents to my extend, none of them explained directly. I'm cleared that image was splitted into 8X8 block.
PLease suggest me a right way if any body found that. Thanks with hope
