Title: Fibre-type light conversion device
Inventor: KIYOFUMI CHIKUMA
IPC: G02B6/02
Filed: 1990-09-07
Abstract: A fiber-type light conversion device comprises: a fiber-type light convention element (10) having a core made of non- linear optical crystal for changing the wavelength of an incident light to half by the phase matching of Cerenkov radiation; and a collimating optical system (11) for transforming an emergent light beam emitted from the light conversion element into a parallel light beam, wherein the collimating optical system has lenses having a large spherical aberation  DELTA  z. Furthermore, the quantity of spherical aberration of  DELTA  z is determined so as to satisfy the following equation of:   DELTA  z =  DELTA  h/tan theta where, on the assumption that a pair of parallel lights are incident to the collimating optical system at heights from the optical axis thereof different from each other, then  DELTA  h represents a difference between a pair of different heights of the parallel lights and  theta  represents an angle of emergence of the emergent light with respect to the optical axis. <IMAGE>

Title: Combining digital video signals and photographic film material and the like
Inventor: RICHARDS JOHN WILLIAM
IPC: G11B27/022
Filed: 1990-11-15
Abstract: A system for combining a 60 field/s 2:1 interlace scan format digital video signal into 24 frame/s progressive scan material, such as film, employs a film scanner 104 to produce a digital video signal from the source film 100, a post- production system 118 for combining with that signal the 60 field/s 2:1 interlace scan format digital video signal (for example from a VTR 112) and a recorder 124 for recording the combined signal on film 102. Motion interpolated compensation is employed at stages of frame rate conversion. In order to obviate the need for more than one stage of motion compensated interpolation between the primary sources and primary output, the post-production system operates on signals in 60 field/s 3232 pulldown format, and motion interpolated compensation is performed only during conversion (at 114) of the 60 field/s 2:1 interlace scan format signal to the 3232 pulldown format. The conversions of the 24 frame/s input signal to 3232 pulldown format (at 106) and of the 3232 pulldown format signal to 24 frame/s format (at 122) do not require motion compensated interpolation because the frame rate is unchanged. <IMAGE>

Title: Moving image encoding apparatus with frame rate and quantization step size control
Inventor: FUJIWARA HIROSHI
IPC: H04N19/176
Filed: 1991-09-02
Abstract: In a moving image encoding apparatus, an image signal is converted into a digital image signal by an A/D converter and is stored in frame memory 110. In addition, a movement vector detector 300 detects a movement of the output of the frame memory 110. In an orthogonal transformer 130, a difference signal between a present frame image which is stored in the frame memory 110 and a previous frame image which is stored in a variable delay frame memory 210 is supplied, in which the difference signal is converted by orthogonal transformation. The orthogonally transformed signal is quantized into a linear or non linear discrete level on the basis of a step width of quantization from a step size controller 600 in a quantizer 140. Then, the quantized data is encoded into a variable length code in a variable length encoder 150. A movement vector detector 300 detects movement of the image by pattern matching processing between the present frame and the previous frame. A movement vector/encoding mode judger 310 generates the movement vector 3 and the encoding mode 4. The variable length code is transmitted to the transmission circuit after adding a movement vector 3 and encoding mode 4. In these operations, a frame rate controller 700 controls the frame skip number and thus the processing rate of each frame image. <IMAGE>

Title: Improving data integrity for document generation
Inventor: HENEY JAMES
IPC: G06F17/24
Filed: 1991-11-19
Abstract: A process is disclosed for reception of data during an interfacing process (5) and storing the data in a memory array. The data in the memory array is transmitted in parallel to a primary database (6) having a fixed record structure, and to a temporary database (10) after generation and insertion of printing instructions. This helps to ensure data integrity in printing and document generation operations which take place with data in the temporary database while accesses are not made to the primary database. The interfacing process (5) controls the situations in which the operator may input data by reference to a counter and display circuit identification numbers so that display circuits are bypassed or used for the interfacing process only if required. By decrementing the counter the control unit allows a user to input data to a specific circuit into which data has been previously incorrectly inputted. <IMAGE>
