摘要： An image processing device includes an image input unit, a shake-amount measuring unit, a shake correcting unit, a dividing unit, a feature-value calculating unit, and an enhancement processing unit. The image input unit receives an input of an image in chronological order. The shake-amount measuring unit measures an amount of shake of an image. The shake correcting unit corrects shake of the image in accordance with the amount of shake measured. The dividing unit divides the image corrected into multiple areas. The feature-value calculating unit calculates a histogram indicating a feature value of an image, for each of the divided areas. The enhancement processing unit determines processing details of enhancement processing to change a form of the histogram for each of the areas in accordance with the measured amount of shake of the image, and conducts enhancement processing on the area based on the histogram calculated for each area.

摘要： One or more techniques and/or systems are provided for video stabilization and/or for image frame generation. For example, a user may instruct a video application hosted on a smart phone to capture a video at a target resolution of 1080 pixels. A padded input having a padded resolution that is larger than the target resolution may be obtained from a capture device, such as a camera of the smart phone. The padded input may be provided to a video stabilization component to obtain a target image frame having the target resolution. In this way, the video stabilization component may perform cropping using padded margin pixels (e.g., additional pixels of the padded input beyond the 1080 pixels of the target resolution) so that image upscaling after cropping (e.g., to account for global warping, etc.) may be mitigated to reduce blur that may otherwise result from image upscaling.

摘要： Reducing consumption of image sensor processor bandwidth includes capturing an image containing subject matter with an image sensor and cropping the image to generate a cropped image. Cropping the image is performed by the image sensor in response to coordinates received from an image sensor processor. The cropped image is sent from the image sensor to the image sensor processor and new coordinates based on a position of the subject matter in the cropped image are determined with the image sensor processor. The new coordinates are then sent to the image sensor.
