The default Matlab format code is RGB24_640x480, which has an aspect ratio of 1.333. The pixel size and format of the default format equals that of the native sensor specs.
sensor size = 1/3"
sensor size = 640x480 pixels (0.3MP)
pixel size = 7.4um
When attached to the microscope, the scale factors are equal to the pixel size divided by the camera adapter magnification (if any) and the objective magnification. When there is no camera magnification:
The Matlab format code that uses all of the native pixels is F7_RGB24_2448x2048. It is a non-standard format (Format_7) with aspect ratio 1.953 and the following specs:
sensor size = 2/3"
sensor size = 2448x2048 pixels (5.0MP)
pixel size = 3.45um
Default Format:
The default Matlab format code is RGB24_1024x768, which has a standard aspect ratio of 1.333. The default pixels are 2x2 bins of the native pixels. Consequently, the pixel size is 6.9um.
When attached to the microscope, the scale factors are equal to the pixel size divided by the camera adapter magnification (if any) and the objective magnification.
When there is no camera magnification, the pixel size of the default Matlab format (6.9um) is divided by the objective magnification.
0.1725um/pixel at 40x
0.3450um/pixel at 20x
0.6900um/pixel at 10x
1.3800um/pixel at 5x
1.7250um/pixel at 5x
2.7600um/pixel at 2.5x
3.4500um/pizel at 2x
Alternative Format:
The Matlab format code F7_RGB24_1600x1200 uses the native pixels but a smaller standard format.
