21	DIRECT CONNECTION OF A DATA STORAGE DEVICE AND A CONSUMER ELECTRONIC DEVICE	PCT/GB2003/004108	2003-09-16	WO2004025652A1	2004-03-25	ARMOUR, Bruce; COMBE, Tony
An optical data storage device (10) adapted to act as a "host" or master on a peripheral interface (14) (e.g. Universal Serial Bus) allows easy (automatic and single button activated) storage of data from a consumer electronic device (16) such as Digital Still Camera (DSC) directly connected to the device on a standard optical storage medium (13) such as CD-R without the need for a (10) personal computer. The images are decompressed and stored (11) within the drive memory (22), re-compressed into a standard format, MPEG-1 (transcoded). The transcoded images are recorded onto the optical medium (13) in a format where each still image is written as a separate image frame. The standard format is compatible with the Video CD (or VCD) standard. This invention also provides a device comprising two peripheral interfaces and adapted (18) to act as a host on both, so that the separate or other form of data storage device including HDD or flash memory can be used.
22	METHOD AND APPARATUS FOR ELASTICITY IMAGING	EP05853350.6	2005-12-07	EP1824390A1	2007-08-29	RADULESCU, Emil, G.
A computational efficient algorithm (12) for compression analysis of free-hand static elasticity imaging performed using medial diagnostic ultrasound imaging equipment (14) offers tissue compression quality and quantity feedback to the operator. The algorithm (12) includes a criterion for automatic selection of the most advantageous pre- and post-compression frame pairs delivering elasticity images of optimal dynamic ranges (DR) and signal-to -noise ratios (SNR). The use of the algorithm (12) in real time eases operator training and reduces significantly the amount of artifact in the elasticity images while lowering the computational burden.

PROBLEM TO BE SOLVED: To provide a digital camera wherein no effect of still picture flash photographing is given onto moving picture data when still picture photographing is executed during photographing of the moving picture. SOLUTION: In compressing moving picture data in compliance with the MPEG standard and recording the compressed data to a memory card, a flash is lighted in any timing of B frames to carry out flash still picture photographing by taking notice of it that image data of the B frames can be generated from the presence of I and P frames when the flash still picture photographing is carried out during photographing of the moving picture.

24	Digital electronic still camera and method of recording image data in memory card	US411152	1995-03-27	US5528293A	1996-06-18	Mikio Watanabe
Image data are recorded in a memory card in a standard DOS-FAT data file structure. When the compression mode is set, original image data is compressed in accordance with a JPEG system, and compressed image data obtained and fixed information in a JPEG header are written in the memory card so as to form a JPEG file. When the uncompression mode is set, the original image data and fixed information in a TIFF header are written into the memory card so as to form a TIFF file. Accordingly, it becomes possible to handle not only compressed image data but also original image data which is obtained in a digital electronic still camera by a lot of types of personal computers.
25	Progressive still frame mode	US768894	1996-12-17	US6108027A	2000-08-22	Barry D. Andrews; Paul A. Voois
A still image is progressively transmitted over a communications channel by computing, encoding, and outputting for transmission difference information representing the difference between the still image and a lower quality representation of the still image that has been received by a remote location. This process is repeated, with additional difference information being generated to supplement the image received at the remote location, such that the quality of the image at the remote location improves over time. The difference information may be encoded in a format compatible with existing video compression standards and processed by a receiving terminal regardless of the presence of still mode capability.

A still image is progressively transmitted over a communications channel by computing, encoding, and outputting for transmission difference information representing the difference between the still image and a lower resolution representation of the still image that has been received by a remote location. This process is repeated, with additional difference information being generated to supplement the image received at the remote location, such that the resolution of the image of the remote location improves over time. The difference information may be encoded in a format compatible with existing vido compression standards and processed by a receing terminal regardless of the presence of still mode capability.

Methods and apparatuses for still image compression, video compression and automatic target recognition are disclosed. The method of still image compression uses isomorphic singular manifold projection whereby surfaces of objects having singular manifold representations are represented by best match canonical polynomials to arrive at a model representation. The model representation is compared with the original representation to arrive at a difference. If the difference exceeds a predetermined threshold, the difference data are saved and compressed using standard lossy compression. The coefficients from the best match polynomial together with the difference data, if any, are then compressed using lossless compression. The method of motion estimation for enhanced video compression sends I frames on an "as-needed" basis, based on comparing the error between segments of a current frame and a predicted frame. If the error exceeds a predetermined threshold, which can be based on program content, the next frame sent will be an I frame. The method of automatic target recognition (ATR) including tracking, zooming, and image enhancement, uses isomorphic singular manifold projection to separate texture and sculpture portions of an image. Soft ATR is then used on the sculptured portion and hard ATR is used on the texture portion.

A still image is progressively transmitted over a communications channel by computing, encoding, and outputting for transmission difference information representing the difference between the still image and a previously-transmitted image that has been stored at a remote location. This process is repeated, with additional difference information being generated to supplement the image received at the remote location, such that the quality of the image at the remote location improves over time. The difference information may be encoded in a format compatible with existing video compression standards and processed by a receiving terminal regardless of the presence of still mode capability.

33	System to capture, store, and retrieve composite video for transmission over telephone lines	US08762884	1996-12-07	US06380967B1	2002-04-30	Frank Sacca
A simple, low-cost videophone system for transmitting and receiving still video images over a standard telephone line in response to a user command. A video processor circuit, comprising an A/D converter, a digital memory, a digital timing circuit, and a D/A converter, can grab a video image from a standard video camera and store one-half the number of lines of a video frame in the digital memory. A still video image can be displayed in a standard TV monitor by repeatedly sending the data stored in the digital memory to the D/A converter. The data stored in the digital memory can be transmitted using a standard modem to the digital memory of an equivalent system at a remote location, and the same still video image can be displayed at the remote location within a short time. Data compression is accomplished during transmission by decreasing the number of significant bits of the data being transmitted and using standard protocols adopted by the modem. Voice communication on the telephone line is temporarily suspended while data is transmitted, and automatically resumed when transmission is complete.
