This might seem like a general question, however I could not find an answer for. Specifically, I am using a CMOS image sensor that has the following general capabilities:
- Array Size: 1280 x 1024 (SXGA), can also take 640 x 480 (VGA)
- Output Formats (10-bit): Raw RGB Data
When I take an SXGA (1280 x 870), i store the file (pragmatically) with a .RAW extension. The file size is about 1000 KB. When I take a VGA (640 x 480) the size is about 300 KB.
Are they already considered as "compressed"? Is is possible to compress these to a smaller size (both lossless tiff and lossy jpeg maybe)?
So far, I am convinced that the images I am taking don't have a specific format and are considered as Raw bitmap. Am I wrong?
References to achieve my goal is much appreciated.
