4 years ago ./step is pretty useless, since it iterates through the sensor data pages one-by-one and does not (if I remember correctly) attempt to do interpolation. Your dumped file is raw data from the sensor, and is coming out exactly how I would expect it- each odd/even frame has a different set of pixels activated in either a scanline or chessboard pattern, and these must be combined to get a full frame of data.
From experience the sensor startup time means you might need to skip a few frames before saving one out as png or jpg.
rgb-to-gif.py has each frame as an individual image from:
This image object can be saved on its own, and you can drop all of the code that collects frames and converts the result to a gif. See the Pillow docs: https://pillow.readthedocs.io/en/3.1.x/reference/Image.html#PIL.Image.Image.save

Hi, how can I save as png or jpg by using rbg-to-gif.py ?
and When I use the compiled step file like this ./step >> /home/pi/Desktop/123.txt
some result values were displayed wrong numbers. ex> Starting... [Datapoint=1] Subpage: 0 +00.00 +154.67 +00.00 +194.23 +00.00 +218.49 +00.00 +238.84 +00.00 +244.62 +00.00 +254.52 +00.00 +259.41 +00.00 +258.42 +00.00 +256.24 +00.00 +251.47 +00.00 +234.59 +00.00 +173.17 this is first line of 32x24 data matrix.
I hope answer my questions. Thank you
