Hello everyone,
Currently, I'm developing image processing on RSK board (RZ/A1H platform) using VDC5 module and using TFT LCD panel (800x480) to show the output image. The BSP package which is downloaded from Renesas website (CMSIS RTOS RTX v2.04).
There are two buffer frames: FrameBuffer_Video (video frame) and FrameBuffer_1 (graphic frame )
+ video frame: YCrCb422 format, after scaling down, the frame buffer size: 400x240x2 = 187.5 [KB] (graphic 0, layer 0) ==> video frame shows the current image which is captured from the camera (VIDEO1 Input)
+ graphic frame: aRGB8888 format, the frame buffer size: 800x480x4 = 1500 [KB] (graphic 2, layer 2) ==> graphic frame shows some information after processing image (for example: text, circle, rectangle, ..)
My question: Is there any way to reduce the size of graphic frame?
Below is some solutions that I tried in before:
1. Scale down the size of graphic frame. But as my understanding, It's just possible for graphic 0 and graphic 1 only, is this right? (in our case, graphic 2 is selected)
2. Change the frame format (for example: RGB888, CLUT,...) ==> I tried with RGB888, however, the graphic 0 did not display due to overlapping of graphic 2.
If you have any ideal or solution, please help me.
Thank you!
