The invention provides an interpolation processing apparatus and method which can be applied, for example, to a personal computer such that it can prevent deterioration in picture quality arising from a conversion ratio by applying it, for example, to image processing. Weighting coefficients are varied based on phase information of output data with respect to input data and a ratio between the input sample number which forms the input data and an output sample number of corresponding output data.

Interpolation/decimation apparatus, interpolation/decimation method and image display apparatus

An image data processing apparatus wherein patterns obtained on the basis of common image information shared by a plurality of pre-conversion pixels with one post-conversion pixel are stored in a calculation data selector, and there is decided a pattern conforming with the pixel data inputted to the calculation data selector via an A/D converter and a frame memory. A calculation coefficient selector selects the calculation coefficients corresponding to the pattern thus decided, and outputs the selected coefficients to a calculator. Then the calculator calculates new pixel data by the use of such calculation coefficients and pixel data inputted thereto. In this apparatus, the post-conversion image formed by converting the number of its pixels can be displayed clearly.

A three-dimensional video signal generator has a high-definition video signal source for generating left and right high-definition video signals having, as left and right video signals, video signals in respective effective scanning periods of odd-numbered and even-numbered field signals of a interlaced-scanning high-definition video signal composed of 1125 scanning lines and having an interlace factor of 2:1. The left and right video signals in the respective effective scanning periods of the left and right high-definition video signals supplied from said high-definition video signal source are vertically compressed in time with a compression ratio of 11:5. The compressed left and right video signals in the odd-numbered and even-numbered fields are combined into a three-dimensional video signal disposed in each of effective scanning periods of odd-numbered and even-numbered field signals of one high-definition video signal, with a pseudo vertical blanking period of a given time duration inserted between the compressed left and right video signals such that the time interval of the compressed left and right video signals becomes a 1/2 field period.

A color image of an object is processed so that the processed image accurately portrays the colors of the object regardless of varying exposure conditions. An object and a color chart that is comprised of a plurality of color chips having known colorimetric parameters are imaged under the same predetermined exposure conditions. Then, colorimetric parameters are determined for each imaged color chip of the imaged color chart. A correlation, between the known and the determined colorimetric parameters, is computed and, on the basis of the computed correlation, the color of the imaged object is corrected.

Color image processing method and apparatus

A digital electronic still camera wherein additional information such as an operation characteristic of the camera can be recorded into and reproduced from a removable record medium. A pickup image signal is picked up by a CCD image sensor and converted into a digital signal by an analog to digital converter. The digital signal is temporarily stored into a digital memory and written onto a removable optical disk apparatus. The digital electronic still camera further comprises an additional information recording and reproducing circuit for recording and reproducing additional information such as an operation characteristic of the camera onto or from the optical disk apparatus.

Digital electronic still camera having removable record means

Tracking control apparatus for a signal reproducing system of the type wherein at least one transducer scans successive parallel tracks on a record medium in which information signals, such as video signals, are recorded. The transducer preferably is of the rotary type so that, during its orbit, it is brought into and then out of reproducing relation with respect to the record medium. Any deviation between the scanning trace of the transducer across the medium and a given track which is being scanned is detected, and a control signal is produced as a function of this detected deviation. The transducer is supported by an adjustable support which is responsive to the control signal so as to displace the transducer transversely of the given track by an amount determined by the control signal. A predetermined sample of the control signal is produced while the transducer scans the given track, and this predetermined sample is stored. Prior to the time that the transducer moves into a reproducing relation with respect to the medium, the stored sample is supplied to the adjustable support so that the transducer is pre-displaced before signals are reproduced thereby.

Tracking control apparatus

A method and apparatus for correcting tracking errors of a transducer which scans successive, parallel, adjacent record tracks of a record medium so as to reproduce information signals therefrom. The information signals, which may comprise video signals, are recorded in the parallel record tracks, and predetermined signals also are recorded at predetermined locations in the information signals. When the information and predetermined signals are played back, at least one cross-talk predetermined signal which is recorded in at least one adjacent track also is played back. The cross-talk predetermined signal is detected and a control signal is produced in response to the level of the detected cross-talk predetermined signal. The position of the transducer with respect to the track being scanned thereby is adjusted in accordance with the control signal. In one embodiment, the control signal is recorded at a predetermined location in each horizontal blanking interval of the video signals; and the horizontal blanking intervals which are recorded in one track are displaced with respect to the horizontal blanking intervals which are recorded in the adjacent track. This displacement of the horizontal blanking intervals, and thus the predetermined signals, in adjacent tracks facilitates the detection of the cross-talk predetermined signals which, for example, may comprise pilot signals.
