Here is a simplified explanation of how it typically happens: 1. Light enters the camera: When you press the shutter button, light enters through the camera lens, which focuses the light onto the image sensor. 2. Image sensor: The image sensor, usually a digital sensor, is a key component in the camera. It consists of millions of photosensitive cells called pixels. The image sensor converts the light it receives into electrical signals. 3. Analog-to-digital conversion: The electrical signals captured by the image sensor are then converted from analogue to digital form. This process assigns numerical values to the signals, creating a digital image representation. 4. Image processing: Once the analogue-to-digital conversion is complete, the camera's processing engine may perform various adjustments to the image, such as noise reduction, colour correction, and sharpening. These adjustments improve the overall quality of the captured image. 5. Compression and storage: The digital image data is compressed to reduce file size while preserving image quality after image processing. Various compression algorithms, such as JPEG, are commonly used. The compressed image is then stored in the camera's memory card or internal memory. 6. Retrieving stored images: When you want to view or transfer the images, you can access the stored images either by connecting the camera directly to a computer or by inserting the memory card into a card reader. The images are then read from the storage medium and can be viewed, edited, or shared. [ 2023-10-08T16:00:31Z ] :flashminiupdate:2024-12-19 :::: 訪問我的 YouTube 頻道 @ Original Cr. ( [ 🔗 點擊‼️ ] )
