Image capturing apparatus, image capturing system, and control method for the image capturing apparatus
An image capturing apparatus comprises an image capturing unit that includes an image sensor that has an effective pixel region and a reference pixel region which outputs a reference signal for correcting an output signal of the effective pixel region. In a case where a predetermined condition is satisfied, a reduction unit reduces a data amount of reference pixel region data that corresponds to the reference pixel region in an image data obtained by the image capturing unit. A recording unit records the image data after the processing performed by the reduction unit.
Encoding and Decoding Selectively Retrievable Representations of Video Content
A system and method disposed to enable encoding, decoding and manipulation of digital video with substantially less processing load than would otherwise be required. In particular, one disclosed method is directed to generating a compressed video data structure that is selectively decodable to a plurality of resolutions including the full resolution of the uncompressed stream. The desired number of data components and the content of the data components that make up the compressed video data, which determine the available video resolutions, are variable based upon the processing carried out and the resources available to decode and process the data components. During decoding, efficiency is substantially improved because only the data components necessary to generate a desired resolution are decoded. In variations, both temporal and spatial decoding are utilized to reduce frame rates, and hence, further reduce processor load. The system and method are particularly useful for real-time video editing applications.

Radiographic image processing apparatus, radiographic image processing method, and storage medium
A radiographic image processing apparatus includes a hardware processor and an image processor. The hardware processor obtains moving image data captured by a radiographic imaging apparatus, causes a display to display a moving image based on the moving image data, and specifies a part of the moving image data that is to be output to an external device. The image processor performs image processing on the part of the moving image data. The hardware processor outputs, to the external device, the part of the moving image data on which the image processing has been performed by the image processor.

Method for processing transform coefficients
Methods, software products, digital cameras and other image processing systems process a set of transform coefficients. In at least one embodiment, the method comprises, for each block of transform coefficients representing an image: ordering the block's coefficients into a sequence; encoding the ordered coefficients to yield a sequence of codewords, each codeword including one or more encoded coefficients; and dividing the sequence of codewords into two or more sub-sequences.
Techniques for selecting resolutions for encoding different shot sequences
In various embodiments, an encoding optimization application encodes a source video sequence. The encoding optimization application partitions a source video sequence associated with a media title into multiple subsequences that include a first subsequence and a second subsequence. The encoding optimization application then generates a first encoded subsequence based on the first subsequence and a first resolution. The encoding optimization application generates a second encoded subsequence based on the second subsequence and a second resolution. Notably, the second resolution is higher than the first resolution. The encoding optimization application then aggregates the first encoded subsequence and the second encoded subsequence to generate an encoded video sequence. At least a portion of the encoded video sequence is subsequently streamed to an endpoint device during a playback of the media title.
