- Phase Detection: The camera uses a dedicated phase detection sensor to measure the phase difference between light rays passing through the lens. This information is used to calculate the distance between the camera and the subject.
Advanced Autofocus Features
Modern mirrorless cameras often feature advanced autofocus capabilities, including:
- Eye AF: This feature uses machine learning algorithms to detect and track the subject’s eyes, ensuring that they remain in sharp focus.
- Subject Tracking AF: This feature allows the camera to track moving subjects, predicting their trajectory and adjusting the focus accordingly.
Image Processing and Storage: The Camera’s Brain
Once the camera has captured an image, it’s time for the processor to take over. The processor is responsible for executing a range of tasks, including:
- Demosaicing: The processor interpolates missing color values from the image sensor data, creating a full-color image.
- White Balance: The processor adjusts the color temperature of the image to match the lighting conditions.
- Noise Reduction: The processor applies noise reduction algorithms to minimize digital noise and improve image quality.
Storage Options: Memory Cards and More
Mirrorless cameras typically use memory cards to store images and video footage. The most common types of memory cards used in mirrorless cameras are:
