Replicated issue on Arduino GIGA R1 WiFi with OV7675 cc @karlsoderby
useGrayScale
set to false
useGreyScale
set to true
Possible solution: Use keyPressed() method in Processing to switch the boolean value for useGrayScale
.
Something like:
void keyPressed() {
if (key == ' ') {
useGrayScale = !useGrayScale;
}
}
This does not require the user to change the useGrayScale
variable manually, and can be switched without restarting the Processing sketch. -> Smoother user experience and less room for error
See case CAMERA_GRAYSCALE:
, it is commented out and currently GRAYSCALE sets to camera to use a bayer output. This is why the grayscale image looks really weird. If you uncomment these lines you can get it to work.

Problem
:disappointed: This is what happens when
useGreyScale
is set totrue
for the Nicla Vision: :smile: This is what is observed, whenuserGreyScale
is set tofalse
for the Nicla VisionThis creates three problems:
Details
The CameraCaptureRawBytes sketch is used to send a video stream over Serial to the computer. Which can then be displayed with the CameraRawBytesVisualizer Processing sketch.
A series of pre-directives, configures the
IMAGE_MODE
to be eitherCAMERA_RGB
(Nicla Vision and GIGA boards) orCAMERA-GREYSCALE
(Portenta H7 family). https://github.com/arduino/ArduinoCore-mbed/blob/0504d34ada3d5aac69eacb481bcdc64860aebca9/libraries/Camera/examples/CameraCaptureRawBytes/CameraCaptureRawBytes.ino#L3-L19In the default configuration, the accompanying CameraRawBytesVisualizer sketch is configured to be compatible with
CAMERA_GREYSCLE
, even though the header comment states that the Processing sketch is for RGB. https://github.com/arduino/ArduinoCore-mbed/blob/0504d34ada3d5aac69eacb481bcdc64860aebca9/libraries/Camera/extras/CameraRawBytesVisualizer/CameraRawBytesVisualizer.pde#L1-L7 https://github.com/arduino/ArduinoCore-mbed/blob/0504d34ada3d5aac69eacb481bcdc64860aebca9/libraries/Camera/extras/CameraRawBytesVisualizer/CameraRawBytesVisualizer.pde#L19-L20Thanks @marqdevx , @Hannes7eicher and @jacobhylen for letting me pick your brains :brain:
