An image processing apparatus includes a class tap selection unit that selects pixel values related to pixels corresponding to a plurality of color components as a class tap, from a first image formed by image signals which are output from a single-plate type pixel portion, a class sorting unit that sorts out target pixels of second images as any one of a plurality of classes on the basis of a feature amount of the class tap, a prediction tap selection unit that selects pixel values related to pixels corresponding to a first color component of the plurality of color components as a prediction tap from the first image, and a product-sum operation unit that uses the pixel values of the first color component of the prediction tap as variables, and operates pixel values of the second images through a product-sum operation using the read coefficient.

Image processing apparatus and method, and program

There is provided an image processing apparatus including: a prediction tap selection unit which selects a pixel which is a prediction tap used for prediction operation for acquiring a pixel value of a target pixel which is a target from a second image obtained by converting a first image, from the first image; a classification unit which classifies the target pixel to any class from a plurality of classes; a tap coefficient output unit which outputs a tap coefficient of a class of the target pixel from tap coefficients, acquired by learning to minimize an error between a result of the prediction operation using a student image corresponding to the first image and a teacher image corresponding to the second image; and an operation unit which acquires a pixel value of the target pixel by performing the prediction operation using the tap coefficient and the prediction tap.

Image processing apparatus, image processing method, and program to prevent degradation of image quality

Image processing apparatus, image processing method, and program

A data recording and reproducing apparatus has facilities for recording and reproducing, inputting and outputting, and editing data and can perform edits by itself. The data recording and reproducing apparatus records AV data inputted from an input port on HDDs by using a recorder and reproducer, and outputs data reproduced from HDDs by the recorder and reproducer through an output port. In an editor inputted is data inputted from outside and data reproduced by the recorder and reproducer. The editor performs edits on at least either of the data above by using a matrix switcher and an audio mixer provided therein. A special effector is utilized as necessary. The editor can output data obtained through editing processing to a switch.

Data recording and reproducing apparatus and data editing method

Provided are a data editing apparatus, a data editing method and a data recording/reproducing apparatus which can easily reedit edited data recorded on a nonlinear-accessible recording medium. When a start point (IN point) or an end point (OUT point) of partial data of edited data to be reedited is specified, a controller controls a recorder and reproducer and HDDs so as to reproduce material data containing the partial data to be reedited in synchronization with operation for changing the specified start or end point of the partial data. Moreover, when operation for determining a new start or end point is performed in a state in which the material data is reproduced in synchronization with changing operation, the controller reedits the edited data in accordance with determining operation. During reediting, the controller reedits data on the basis of a temporary file. The controller reedits data while reproducing the same reproducing state as the reproducing state after reediting.

Data editing apparatus, data editing method and data recording/reproducing apparatus

A data recording and/or reproducing apparatus for recording, reproducing or editing of video and audio data includes an input processing unit, having an input processing control portion for controlling data inputting to a recording medium, an output processing control portion for controlling data outputting processing for the recording medium and a main controller for comprehensively controlling the input processing unit and the output processing unit. By the input processing controlling portion and the output processing controlling portion, the input processing unit and the output processing unit can be operated independently of each other. On the other hand, the main controller is able to control the input processing controlling portion and the output processing controlling portion so that these two portions will execute a concerted operation. In this manner, the data recording and/or reproducing apparatus can record and/or reproduce data on or from a non-linear-accessible recording medium while the data recording and/or reproducing apparatus can be built into a routine linear editing system to execute an operation in no way inferior to that of a VTR equipment.

Data recording and/or reproducing apparatus

In a data recorder-reproducer, and a bit map data processing method, a control program processing method and a setting data processing method of the data recorder-reproducer, bit map data supplied from the external is taken in, and the taken bit map data is superimposed upon data which is reproduced from a recording medium or is input from the external. In addition, first program data stored in a rewritable storing means is rewritten into second control program data supplied from the external. Furthermore, settings of an input/output means is changed based on the setting data supplied from the external.

A data recording/reproduction apparatus and a data recording/reproduction method according to the invention can effectively and economically utilize the limited resource of hard discs when editing files by defining the editing points on a plurality of data recorded on a non-linearly reproducible recording medium.

Data recording/reproduction apparatus and data recording/reproduction method

Data editing apparatus, data editing method and data recording/reproducing apparatus for re-editing formerly edited data

An AV data recording/reproducing apparatus which has a recording section for recording AV data, e.g., a disk array section. Each frame unit is edited to generate editing result information. The AV data is read from the disk array section on the basis of the editing result information to reproduce the edited AV data. A command analysis section receives various linear editing commands generated by a linear editing machine for generating editing information and from which a command is produced to generate the editing result information. Thus, an editing operation using a familiar linear editing machine can be performed.

A control command attaching the same identifier to related commands is input from an application to an AV data processing control device. Further, a command for linking this identifier and a trigger generated by a contact input-,is input. When the contact input-,is generated, all control commands containing the identifier are executed. Further, when the link of the contact input-,and the identifier of the control command is invalidated, even if the contact input-,is generated, none of the linked control commands are executed. The execution of the control commands is carried out by controlling the controlled devices by the IDCs.
