In ophthalmology, Eye dicom images coming from Visucam software / Clarus software with Photometric Interpretation RGB are looking as blue when we export to our software.

To view these images we convert dicom to JPEG using pixel data of dicom images. When we view these converted JPEG images to our software it looks like bluish but the original images are in green or orange(Fundus) format.

can anyone help with this? Original Image

This question is way too broad and clearly shows no researches efforts. That would have been faster to use <your favorite search engine> and find the solution than typing this question. – Cid
I think you need to increase the resolution of the jPEG conversion. The color change is probably due to lower resolution. See WIKI : en.wikipedia.org/wiki/JPEG – jdweng

Sometimes the software that produces the DICOM files set the color space to "RGB" for images compressed using the baseline jpeg, but the color space for baseline jpeg images is assumed to be YBR.

Check the color space and the transfer syntax in the DICOM file: if it has a transfer syntax set to lossy jpeg and it specifies the color space as "RGB" then you found the problem.
