Granted Patent: Aperture's Picture Straightening Tool

Apple's invention relates to manipulating digital images and, more specifically, to changing the changing the rotational orientation of a digital image relative to the device on which the image is displayed.

Background

How a work of art is presented to a viewer can have a significant effect on whether the aesthetic merits of the work are fully appreciated. For example, if a painting is tilted, viewers may be so distracted by the tilt of the painting that they cannot fully appreciate the painting's aesthetic qualities.

The need to present art at the correct rotational orientation applies equally to photographs. Like paintings, photographs may be badly oriented relative to the surroundings in which they are displayed. However, the visual content of a photograph may also be badly oriented relative to the photograph's own peripheral shape. Specifically, most photographs are captured as rectangular images. If the photographer is not holding the camera perfectly level relative to the ground at the time a photograph is taken, the image in the photograph may appear tilted relative to the rectangular peripheral shape of the photograph. In such cases, if the photograph is displayed in a manner that correctly orients the visual content of the photograph with the viewer, then the peripheral shape of the photograph will appear tilted. Conversely, if the photograph is displayed in a manner that correctly orients the peripheral shape of the photograph with the viewer, then the visual content of the photograph will appear tilted.

One benefit of digital images is that they may be manipulated to compensate for undesirable characteristics in the originally captured image. For example, many software tools are available to brighten a digital photo when the originally captured version of the photo is undesirably dark. Software tools may also be used to adjust the rotational orientation of digital photos. Unfortunately, just as it is often difficult to determine the perfect rotational orientation of a physical painting without a level, it can be difficult to determine the perfect rotational orientation of a digital image. Further, even when adjustments are made to achieve the perfect rotational orientation of the visual content of a digital photo, there remains the problem of what to do about the incorrect rotational orientation of the peripheral shape of the digital photo that results from such adjustments.

Apple's patent solves these problems.

Method for variable length decoding using multiple configurable look-up tables: Apple's invention relates to data processing systems using vector processing and Very Long Instruction Word (VLIW) architecture, more particularly to variable length decoding using multiple look-up tables.

Multiple Media Type Synchronization between Host Computer and Media Device: Apple's invention relates to improved techniques for transferring media assets between a host computer and a media device. The transfer of media assets between a host computer and a media device can be referred to as synchronization. According to one aspect of the invention, media assets being transferred can be formatted (e.g., rendered) in advance at the host computer and then delivered to the media device. According to another aspect of the invention, media assets can be grouped into collections and transferred on a collection basis. According to still another aspect of the invention, media assets to be transferred can be limited based on an amount of storage capacity available at the media device. According to yet another aspect of the invention, media assets of different media types can be transferred in accordance with different priorities.

The invention can be implemented in numerous ways, including as a method, system, device, apparatus, or computer readable medium.

DMA Controller Configured to Process Control Descriptors and Transfer Descriptors: Apple's invention relates to the field of integrated circuits and, more particularly, to direct memory access (DMA) in systems comprising one or more integrated circuits.

Method and Apparatus for Identifying User-Selectable Regions within Multiple Display Frames: Apple's Abstract: The method and apparatus determine a specific position of a user-selectable region at a particular point in time within a sequence of display frames. The method and apparatus first interpolate between a first matrix representing the user-selectable region at a first point in time and a second matrix representing the user-selectable region at a second point in time. In one embodiment, the matrix generated by this interpolation is then applied to a region definition for the user-selectable region to determine the specific area occupied by the region at the particular point in time. According to one embodiment, the first matrix and the second matrix are both stored within the same sample of a container track. This sample corresponds to one or more frames of the sequence of display frames. In an alternate embodiment, the first matrix and the second matrix are stored in two separate samples of the container track.

Spooling during video format conversions: Apple's invention relates to converting video from one format to another and, more specifically, converting video from an inter-frame compressed format to an independent-frame format (a format in which the video information is represented without inter-frame dependencies).
