An information processing apparatus including: a plurality of data processing functional blocks each used for carrying out individual data processing; a flow control section configured to execute control of data flows among the data processing functional blocks; and a control section configured to carry out a setting process to set the data processing functional blocks and the flow control section. The control section acquires configuration information in accordance with a task list for data processing to be carried out; carries out the setting process to set the data processing functional blocks and the flow control section on the basis of the acquired configuration information; and constructs a data processing configuration adapted to various kinds of data processing to be carried out.

Information processing apparatus, information processing method and computer program

An edge function is computed from two vertex coordinates given by a rendering target line. Gradient determination is then performed on the edge function, and the functions representing two shift lines that are formed by translating the rendering target line in the y-axis direction or x-axis direction depending on the angle formed by the rendering target line and the x-axis of the rendering plane coordinate system by 0.5d and &#x2212;0.5d will be computed, where d denotes the width of one pixel. Then, the number of subpixels included in a parallelogram, which has four points of the starting points and ending points of the two shift lines as vertices, is acquired so as to determine the pixel value of each pixel based on the number.

Drawing method, image generating device, and electronic information apparatus

A drawing processing apparatus is provided to solve the problems in which pixels of a drawing primitive with sub-pixel information may have an increased amount of data causing a burden on implementation. A setup processing unit sets up various parameters to allow a digital differential analyzer (DDA) to process the stream of a drawing primitive supplied from a primitive input unit. The DDA performs DDA processing on the drawing primitive supplied from the setup processing unit for conversion into pixel data. The DDA performs the DDA processing on a per rectangular pixel set basis along a scan line to output the pixel data of the drawing primitive on a per rectangular pixel set basis. A compression encoding unit encodes the sub-pixel information of each pixel contained in the rectangular pixel set by run length encoding for output to a FIFO buffer.

Drawing processing apparatus and method for compressing drawing data

A scheme for detecting telop character displaying frames in video image which is capable of suppressing erroneous detection of frames without telop characters due to instability of image features is disclosed. In this scheme, each input frame constituting the video data is entered, and whether each input frame is a telop character displaying frame in which telop characters are displayed or not is judged, according to edge pairs detected from each input frame by detecting each two adjacent edge pixels for which intensity gradient directions are opposite on some scanning line used in judging an intensity gradient direction at each edge pixel and for which an intensity difference between said two adjacent edge pixels is within a prescribed range as one edge pair, edge pixels being pixels at which an intensity value locally changes by at least a prescribed amount with respect to a neighboring pixel among a plurality of pixels constituting each input frame.

A video data storage and playback scheme in which the playback of video data that has been interrupted due to the occurrence of the overtaking at the storage device can be automatically resumed at the playback device is disclosed. The storage device is controlled to transmit the read out video data to the playback device by attaching control data indicating that it is video data read out after an overtaking occurred, when the read out video data is video data stored after an occurrence of the overtaking in which a reading position of video data in a process of being read out from the storage device in response to the request from the playback device overtook a writing position of video data in a process of being written into the storage device. Then, the playback device is controlled to resume playback of video data that has been interrupted due to the occurrence of the overtaking, upon detecting the control data.
