TDA4VEN-Q1: TIOVX: Upscale a small-resolution image

Part Number: TDA4VEN-Q1

Hello!

I have a 640x480 raw8 monochrome camera that I would like to upscale to 1920x1080 to fit onto a display.

Is it possible to do this via the multi-scalar or some other kernel?

Hi Stuart,

No, multi-scalar supports only downscaling.. You could probably use inline scalar in DSS pipeline to upscale this resolution.

Brijesh,

Sorry for my late reply. How do I utilize inline scalar in the DSS pipeline? Is this some kind of argument to the TIOVX node - or is it somewhere in the DSS driver?

thank you!

EDIT: I see now that it upscales automatically if the input image is smaller than the display output size. thanks!

Hi Stuart,

That's true, if the input size is smaller than the final output from the display, then driver/node automatically enables scalar for upscaling/downscaling.
