  • Patent number: 9635212
    Abstract: An image is compressed according to a compression ratio selected based on a compression metric. In one embodiment, the compression metric is based on image characteristics indicative of the amount of image noise in an image, such as gain and lux. Greater compression ratios are used for image having compression metrics indicating a higher degree of noise. Because an image with higher image noise levels already has a reduced visual quality, the impact of higher compression is less significant as compared to the impact of compression on images having low image noise. In an embodiment, an image is divided into a number of regions, for each of which a compression metric and corresponding compression ratio is determined, so that regions of the image having high image noise may be compressed more than regions having low image noise.

    Abstract: Systems, methods, and computer readable media to provide improved autofocus operations are described. In general, techniques are disclosed that show how to improve contrast-based autofocus operations by applying a novel threshold-and-select action to window-specific focus scores. More particularly, techniques disclosed herein may evaluate a multi-window autofocus area over a burst collected group of images. For each captured image, focus scores for each window within an autofocus area may be collected, aggregated and then consolidated to identify a single focus metric and its associated lens position for each window. The window-specific focus scores may be reviewed and selection of a “best” autofocus lens position made using a selection criteria. The specified criteria may be used to bias the selection to either a front-of-plane (macro) or back-of-plane (infinity) focus position.

  • Patent number: 9350920
    Abstract: An image generating method of an image generating apparatus is provided. The method includes displaying a live view image on a screen of an image generating apparatus, comparing a shutter speed with a frame rate of the live view image when there is a command to image a still image during the displaying of the live view image, adding current frame data of the live view image to next frame data of the live view image to generate added next frame data when the shutter speed is smaller than the frame rate of the live view image, and reading out the added next frame data of the live view image to generate the still image.

  • Patent number: 9313414
    Abstract: The present invention discloses a region based shutter adaptation method for image exposure. The method includes the steps of: (a) providing an image which is non-uniformly illuminated; (b) segmenting the image into two or more non-overlapping regions; (c) identifying brightness values for each of the regions when more than one brightness value has been produced for each of the regions; (d) applying the whole image with different shutters for different regions; and (e) exposing different regions for different exposure durations according to the brightness values respectively assigned to the regions, so that the present invention is capable of enabling different regions within the whole image which is non-uniformly illuminated to have different shutter adaptions.

  • Patent number: 9288456
    Abstract: First image data obtained by capturing an image of a subject under a first light condition, and second image data obtained by capturing an image of the subject under a second light condition different from the first light condition are input. The sampling positions of colors used to generate correction parameters are acquired. First color signal values are sampled from the sampling positions in the first image data, and second color signal values are sampled from the sampling positions in the second image data. Correction parameters used to correct the first image data which depends on the first light condition into image data which depends on the second light condition are generated based on the first and second color signal values.
