Problems solved by technology

It is evident from these figures that the images taken with the existing system contain white spots and are overexposed due to the various limitations mentioned above
[0009] As a result, the current system results in images that may be overexposed, contain many white patches, and look unnatural
None of the current digital camera systems provide automatic flash adjustments to produce natural, correctly exposed images for all types of scenes and lighting

Abstract

A system and method for intelligent flash intensity control are provided. The method includes that: receiving an input from a user to open a camera [206] to capture a media. Thereafter, a position of a lens [206B] of the camera [206] is determined and a luminance level of a preview frame is detected. Further, a scene type for the preview frame is determined. Thereafter, a flash intensity control value is dynamically calculated based on the determined position of the lens [206B], the detected luminance level and the determined scene type. The flash intensity control value is then used to produce a flash, with an intensity value equal to the value of the flash intensity control, to capture the media.

Description

technical field [0001] The present disclosure relates generally to electronic digital cameras, and more particularly to systems and methods for intelligent flash intensity control in cameras. Background technique [0002] The following description of related art is intended to provide background information related to the field of the present disclosure. This section may include specific aspects of technology that may be related to the various features of this disclosure. It should be understood, however, that this section is intended only to enhance the reader's understanding of the general field of the disclosure, and not as an admission of prior art. [0003] Many different techniques have been developed to provide the optimal exposure for a scene to take a picture of the scene using a conventional digital camera. This technique varies from using a physical light meter separate from the camera to provide the optimal amount of light to systems involving the use of artifi...
