Current Configuration

The current config.json for camera1 includes:

{
  "name": "camera1",
  "machine_topic": "blower_separator",
  "storage_path": "/storage/camera1",
  "exposure_ms": 1.0,
  "gain": 3.5,
  "target_fps": 0,
  "enabled": true,
  "auto_start_recording_enabled": true,
  "auto_recording_max_retries": 3,
  "auto_recording_retry_delay_seconds": 2,
  "sharpness": 100,
  "contrast": 100,
  "saturation": 100,
  "gamma": 100,
  "noise_filter_enabled": false,
  "denoise_3d_enabled": false,
  "auto_white_balance": false,
  "color_temperature_preset": 6500,
  "anti_flicker_enabled": true,
  "light_frequency": 1,
  "bit_depth": 8,
  "hdr_enabled": false,
  "hdr_gain_mode": 0
}

Camera Preview Enhancement

Important Update: The camera preview/streaming functionality has been enhanced to apply all default configuration settings from config.json, ensuring that preview images match the quality and appearance of recorded videos.

What This Means for Camera1

When you view the camera preview, you'll now see:

Manual exposure (1.0ms) and high gain (3.5x) applied
50Hz anti-flicker filtering active
Manual white balance with balanced RGB gains (1.0, 1.0, 1.0)
Standard image processing (sharpness: 100, contrast: 100, gamma: 100, saturation: 100)
D65 color temperature (6500K) applied

This ensures the preview accurately represents what will be recorded.

Notes

Machine Topic Correction: The machine topic has been corrected from "vibratory_conveyor" to "blower_separator" to match the camera's actual monitoring purpose.
Manual White Balance: The camera is configured for manual white balance with D65 color temperature, which is appropriate for daylight conditions.
RGB Gain Support: The current configuration system needs to be extended to support individual RGB gain values for manual white balance fine-tuning.
Anti-Flicker: Enabled to reduce artificial lighting interference, set to 60Hz to match North American power frequency.
LUT Mode: The camera uses dynamically generated LUT with gamma=1.00 and contrast=100, which provides linear response.

Future Enhancements

To fully support all settings shown in the screenshots, the following parameters should be added to the configuration system:

wb_red_gain: Red channel gain for manual white balance (0.0-3.99)
wb_green_gain: Green channel gain for manual white balance (0.0-3.99)
wb_blue_gain: Blue channel gain for manual white balance (0.0-3.99)
lut_mode: LUT generation mode (0=dynamic, 1=preset, 2=custom)
lut_preset: Preset LUT selection when using preset mode
