Augmented Reality (AR) and Virtual Reality (VR) are revolutionizing the way users interact with digital environments, but their efficiency is greatly determined by image quality, depth, and real-time processing. In this case, computational photography is playing a very important role in ensuring the efficiency of AR and VR in terms of image quality and processing. The importance of computational photography is also reflected in the growing computational photography market, which is mainly attributed to the growing use of AR and VR in various industries.
Based on various publications, computational photography is a combination of various image processing techniques aimed at enhancing the accuracy and quality of visual outputs beyond hardware capabilities.

Enhancing Depth Perception and Spatial Mapping
One of the most important tasks of computational photography for AR and VR systems is depth estimation. Depth estimation is important for blending digital objects with the real world, especially for AR systems, as well as for creating realistic environments for VR systems.
For AR systems, depth estimation is done through stereo vision, multi-camera systems, and AI-based depth sensors. These systems process thousands of data points per frame, which are used for determining the position of an object. Studies have revealed that there are different stages involved in AR systems, including image acquisition, extraction, and geometric verification, which are done through computational photography.
For AR systems, depth estimation systems have the potential to improve object placement accuracy by more than 30 percent compared with traditional systems.

Improving Image Quality and Realism
Visual realism is important in terms of user immersion. Computational photography is helpful in enhancing image quality. The techniques include HDR imagery, image noise reduction, image super resolution, and image fusion.
Research on 360-degree visualization in a VR environment shows that enhancing image resolution and image processing has a direct impact on user comfort.
Image enhancement, which is done by AI, is helpful in AR/VR in terms of image processing in real-time. Advanced image processing is able to process millions of pixels in a single frame with low latency. This is important since any latency above 20 milliseconds affects immersion.

Enabling Real-Time Processing and Interaction
Since AR/VR applications are to be rendered in real-time, they need to possess fast rendering capabilities. Computational photography helps in providing fast image processing capabilities, which are necessary for interaction.
Studies show that AR/VR technologies use different image processing techniques like image recognition, stereo vision, and depth sensing. These technologies are very important to provide interaction.
For example, AR devices are able to process images at 60+ FPS. Advanced AR/VR systems are able to process images at 90-120 FPS to prevent motion sickness.

Supporting Advanced Features like Object Recognition and Tracking
In addition to this, computational photography is also being used to deliver more advanced features like object tracking and scene understanding. These are very important for gaming, healthcare, retail, and industrial training.
For instance, high-frequency tracking systems are being developed to function at very high speeds compared to traditional camera-based systems. This helps AR systems to recognize objects with precision.
Expanding Applications Across Industries
The scope of computational photography can be extended to various sectors.
In healthcare, surgeries are done with the aid of AR. In education, immersive education helps in better student engagement and knowledge retention. Research reviews show that AR technology is used in all levels of education, particularly in sciences, math, and technology.
In industrial settings, VR helps in simulating training environments, while AR helps in maintaining equipment.
