4317 results about "Image processing" patented technology

In imaging science, image processing is any form of signal processing for which the input is an image, such as a photograph or video frame; the output of image processing may be either an image or a set of characteristics or parameters related to the image. Most image-processing techniques involve treating the image as a two-dimensional signal and applying standard signal-processing techniques to it. Image processing usually refers to digital image processing, but optical and analog image processing also are possible. This article is about general techniques that apply to all of them. The acquisition of images is referred to as imaging. Closely related to image processing are computer graphics and computer vision. In computer graphics, images are manually made from physical models of objects, environments, and lighting, instead of being acquired from natural scenes, as in most animated movies. Computer vision, on the other hand, is often considered high-level image processing out of which a machine/computer/software intends to decipher the physical contents of an image or a sequence of images.

Apparatus and method for optimized compression of interlaced motion images

An interlaced image processing module and corresponding method facilitate improved processing of interlaced motion images. In one embodiment, the interlaced image processing module receives image data frames having interlaced first and second fields and produces a reference field and error field. The reference field corresponds to the still image content of the interlaced frame, whereas the error field corresponds to the motion content of the interlaced frame, particularly the motion between fields. Motion between fields is thus represented in the error field, without redundant representation of the still image content provided by the first field. Where there is little motion between fields, the error terms will be small so the predictor preserves the coding efficiency provided by any auto-correlation in the image. Further, the interlaced image processing method does not rely upon pixel group classification, and thus avoids classification errors, and the loss of coding efficiency from still image content in motion classified blocks. Finally, problems presented by relative motion between fields are avoided, as are local artifacts. Another embodiment transforms the interlaced fields into frame data having a high frequency field and a low frequency field.

Apparatus for communicating over a network images captured by a digital camera

An apparatus is provided for communicating over a network images captured by a digital camera, such as a digital camera without an on-board network interface. The apparatus includes a housing separate from the digital camera having a processing unit with memory for storage of images, a camera interface card received in a memory card slot of the digital camera, and a cable or wireless connection coupling the camera interface card to the processing unit for data communication. The apparatus emulates a memory card to the digital camera, such that the digital camera's electronics operate with the memory of the processing unit through the camera interface card, as if such memory was on a memory card located in slot of the digital camera. Images captured by the digital camera are transferred, via the camera interface card and cable, to memory of the processing unit, and the digital camera can access images stored in memory of the processing unit. The processing unit has a wireless data network interface and Ethernet communication interface, whereby captured images stored in memory of the processing unit are queued in real-time for network transfer, and subsequently transferred via one of the network communication interfaces, to a computer system, such as an web site or file server, at a network destination address configurable in the processing unit. Data may be inputted by the user before and/or after image capture for association with images prior to their network transfer. The housing for the processing unit may be shaped like a motor drive unit and attached to the bottom of the camera, or worn by the user of the camera in the form of a belt pack or backpack.

Image processing method, system, program, program storage medium and information processing apparatus

This invention provides the following environment. That is, an original document file corresponding to a document to be copied is specified from image data of that document to be copied, and a print process is made based on the specified file so as to prevent deterioration of image quality. Also, when a document to be copied is not registered, a registration process is executed to suppress deterioration of image quality in an early stage. Furthermore, since the document is converted into vector data, re-use of such document is facilitated, and deterioration of image quality can be suppressed even when an image process such as enlargement or the like is made. To this end, when an original digital file cannot be specified, an apparatus of this embodiment executes a vectorization process (S54), converts the obtained vector data into a data format that can be re-used by an application (S55), and registers the converted file in a file server (S56). With this registration process, since the location of the file is settled, that location information is composited on an image to be scanned using an identifier such as a two-dimensional barcode or the like (S48), and the composite image can be printed (S49). Even when the printed document is scanned again, a registered digital file can be easily specified.
