Smartphone camera resolution is increasing fast to meet the user expectation. With the increase in resolution the need of storage capacity as well as power consumption in processing the images is increasing. Though a user can set the resolution of an image before capture, most of the time the user does not change the pre-selected resolution for capturing multiple images. If the pre-selected resolution is maximum, the user may consume too much storage and if the preselected resolution is minimum the user may lose significant information for some images. Thus a fixed resolution is not recommended for all the images. In this work we propose a method of automatically suggesting an optimum capture resolution based on the content of the preview image, and works in real time. The proposed method enables the user to capture an image with varying resolution depending on the quality of the preview. This method may be useful in saving a significant memory space in storing captured images as well as power consumption without loss of quality of the image.
