Improvement of the Algorithm of Determination Parameter of Photography in the Conditions of Light Sensitivity

The concept of critical modes of observation of an object with the help of discrete photographic equipment and their influence on the quality of a digital image is defined. A feature of such modes is the inability to obtain a guaranteed quality of the digital image of the object of observation. During photography, this is characterized by a significant change in the level of external light sensitivity of the subject, the possible distance of photography, the operational shift of the image and other factors that affect the image quality. But observation in these conditions increases the activity, completeness and timeliness of documenting the image of the object. The article offers a formalized description of the successful observation of the object. It contains the concept of a given probability of recognition of the object of observation of its image. It determines the rational level of image quality. The parameters of the photographic equipment which can provide the predicted qualitative image are offered. Such parameters of the photographic equipment are its light sensitivity and resolution. The algorithmic relationship between the limit values of light sensitivity and resolution is determined. It allows assessing the degree of achievement of the highest perfection of a discrete iconic tool, taking into account the specified depth of recognition of the object by its image. An algorithmic assessment of the influence of photographic noise on image quality is proposed. The algorithms developed in the article are verified by a computational experiment. It allowed us to estimate the rational ranges of light sensitivity that won't affect the resolution of the digital image of the observed object.
