Step 1: Capturing Light
- Light rays from the scene pass through the camera lens and strike the sensor.
Step 2: Photodiode Conversion
- Each photodiode on the sensor converts light into an electrical charge.
Step 3: Charge Accumulation
- The electrical charge accumulates in each photodiode during the exposure time, proportional to the intensity of light falling on it.
Step 4: Readout and Amplification
- After exposure, the accumulated charges are read out from each photodiode and amplified.
Step 5: Analog-to-Digital Conversion (ADC)
- The amplified analog signals are converted into digital values by an analog-to-digital converter (ADC).
Step 6: Digital Image Creation
- The digital values are processed to create a digital image. This may include noise reduction, color correction, and other image processing techniques.
Step 7: Image Storage
- The digital image is compressed (often using JPEG) and stored in the camera's memory card.
Step 8: Image Display
- You can view the captured image on the camera's LCD screen or transfer it to a computer or other device for editing, sharing, or printing.
