Does SoftISP supports 4K resolution?

[chandresh_tank]

I am trying to port an OpenCV based application from iOS to i.MX8MQ based platform in which i have connected IMX334 based sony camera to its MIPI CSI bus. 

The 4k raw image captured by IMX334 camera sensor will be fed to the SoftISP module for debayering, Whitebalance and further processing. 

Does SoftISP support 4k resolution debayering? and Can you please provide the performance numbers of SoftISP for debayering for 4K resolution?

on imx8m, SW ISP can be used by openCL, which can support 4K resoltuion

Joan,

I would like to add softisp to my build with AGL, with reference to bb file and bbappend file can you please suggest for imx8mqevk ?

Hi Joan, 

Thank you for responding quickly. 

Is there any sample application in which SoftISP is processing a video feed?

and Do you have performance data of SoftISP processing 4K image?

The root directory is called SoftISP under OpenCL. There are three subdirectories in the root directory:
1)Executable binary "SoftISP"is in folder of SoftISP.
2) Build - contains OBJ files generated by the SW-ISP.
3)Content - contains the prepared raw images "bayer.data" in the *.data format. The raw image was captured by Bayer camera (resolution: 1920 x 1080, Bayer array: BG/GR). The application can read raw data by the filename of "bayer.data"
4)Source - contains source code running on CPU and GPU. "isp_kernel.cl" is C code of kernels.

performance:

High application performance (OpenCL: ~28 fps, 1080p, OpenVX: ~39fps, 1080p).
