In one example, a plurality of image frames captured by a digital camera unit are received. Received image frames may be still images or frames of a video sequence. Received image frames are automatically analyzed for detecting a possibility to process a plurality of image frames.

Automatic image frame processing possibility detection

A computing device is described which has a memory holding at least two input images depicting different parts of a panoramic scene, the images having been captured by a user moving the camera by hand to capture the panorama. The computing device has an image stitching component configured to identify, at a processor, a region of overlap between the at least two images and to calculate a displacement vector for each of a plurality of warp points in the region of overlap. The image stitching component is arranged to warp a second one of the at least two images using the warp points; and to join the warped second image to the first image.

Image stitching

An apparatus and a method for capturing a bracketing sequence of digital image frames. An apparatus includes a digital camera and at least one memory including camera settings. The apparatus further includes a processor configured to control operation of the digital camera together with the camera settings. The apparatus further includes a user interface for at least one of inputting and adjusting the camera settings. The user interface enables user to manually define an image capture sequence including a first camera setting input and a second camera setting input. The processor is configured to store the image capture sequence in the at least one memory, and to control the digital camera to capture a bracketing sequence of digital image frames using the first camera setting input and the second camera setting input.

Methods and apparatuses for capturing multiple digital image frames

An apparatus and a method for capturing image frames using interlaced exposure. The apparatus includes a digital camera and a memory. The digital camera includes an image sensor and the memory includes camera settings. The apparatus further includes a processor and a user interface. The user interface enables a user to manually input or adjust image capture parameter values including at least one first capture parameter value for a first set of pixels from the image sensor, and, at least one second capture parameter value for a second set of pixels from the image sensor. The processor controls the digital camera to expose the first set of pixels using the at least one first capture parameter value and the second set of pixels using the at least one second capture parameter value, where exposures of the first set of pixels and the second set of pixels overlap in time.

Methods and apparatuses for capturing image frames with interlaced exposure

A method and an apparatus for generating panoramic images are presented. The method includes receiving a set of consecutive image frames. A portion of a first image frame is extracted to configure an intermediate panoramic image. The intermediate panoramic image is augmented by stitching image frame portions to the intermediate panoramic image. The image frame portions are selected from individual image frames in a subset of image frames including consecutive image frames from a second image frame to a penultimate image frame. Each image frame portion is selected based on a sharpness measure and an overlap measure associated with the respective individual image frame. The overlap measure is determined based on a comparison of the respective individual image frame with a current state of the intermediate panoramic image. A portion of a last image frame is stitched to the augmented intermediate panoramic image to configure the panoramic image.

A method and an apparatus for video content stabilization are presented. The method includes causing capture of a series of image frames of a video by a camera. The video is captured by detecting a movement of the camera during capture of each image frame and effecting optical image stabilization to compensate for the detected movement. At least one of a lens assembly and an image sensor is reset to a pre-capture position subsequent to the capture of the each image frame. The method further includes performing digital image stabilization (DIS) for an image frame based on the movement of the camera detected for the image frame and the movement of the camera detected for at least one other image frame. The DIS is performed for one or more image frames to substantially remove an effect of the movement of the camera from the one or more image frames.

Method and apparatus for video content stabilization

According to one aspect, there is provided an apparatus comprising at least one processing unit and at least one memory. The at least one memory stores program instructions that, when executed by the at least one processing unit, cause the apparatus to control a first set of pixels of an image sensor for exposure of a scene for a camera viewfinder, the image sensor having at least two sets of pixels enabling different exposure times, and control a second set of pixels of the image sensor for exposure analysis of the scene for images to be captured for a multi-exposure image.

Provision of exposure times for a multi-exposure image

An apparatus for capturing two different types of light simultaneously is described. A filter array is used for filtering light arriving at an image sensor. The filter array comprises per pixel filters arranged in rows, so if a row comprises filters, they are all of the same type. Different exposure settings may be used for rows having different filter configurations.

Filter arrangement for image sensor

There is disclosed a method for seamlessly replacing areas in a digital image with corresponding data from temporally close digital images depicting substantially the same scene. The method uses localized image registration error minimization over a fixed preliminary boundary. A least cost closed path which constitutes a boundary for the area to be replaced is calculated using dynamic programming. The replacement area is blended such that image data information from one image is seamlessly replaced with image data information from another image.

Digital image manipulation

A method comprising operating in a single-frame capture mode, receiving indication of a first input associated with invocation of a first zoom out operation, and transitioning from the single-frame capture mode to a first multiple-frame capture mode based, at least in part, on the first zoom out operation is disclosed.
