Study on Auto-Focusing Technique in Digital Still Camera Based on Image Analysis

Nowadays digital still camera has progressed quickly. As an important method to improve the resolution of the image captured by digital still camera, autofocusing technique is attracting more and more attention A focusing technique based on image analysis is discussed. A fivefield focusing technique is proposed to remedy the onefield focusing technique in the existing digital still cameras. Neural network is used to optimize the weights of these five fields The model has been applied to relevant products. The experiments show that the model gives accurate results and can work steadily
