An inspection apparatus specifies a region for displaying an advertisement from an image of a virtual space. The inspection apparatus comprises: an image mapping unit that maps an image, which uses a color that is not used in the virtual space and where the display status of the advertisement varies in accordance with a viewpoint of a user, on a region where the advertisement is to be displayed in the virtual space; an inspection image acquiring unit that acquires a virtual space that is actually displayed on a screen on a frame-by-frame basis; and an advertisement region extracting unit operative to extract, by color-filtering the acquired image of the virtual space, a region that is rendered with a color that is not used in the virtual space, as a region for displaying the advertisement perceived by a user.

Image processing apparatus and image processing method

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

A drawing apparatus includes a reception unit, a first holding unit and a drawing processing unit. The reception unit receives graphic information. The first holding unit holds a plurality of first data which is a part of the graphic information received by the reception unit, in association with identification numbers assigned to the first data. The drawing processing unit draws a graphic on the basis of the first data held in the first holding unit. The drawing processing unit uses the plurality of the first data in a same task to draw the graphic. The reception unit records the identification numbers of the first data and a synchronization flag in order of reception. The synchronization flag is set for the first data received first among the plurality of first data processed by the same task in the drawing processing unit.

Drawing apparatus and method for processing plural pixels in parallel

An image processing apparatus capable of efficient rendering is provided. In an image processing apparatus which renders, in a screen coordinate system, unit figures each constituting the surface of a three-dimensional object to be rendered, a rasterizing unit divides a rendering area corresponding to a screen into multiple unit areas, while a first unit figure is projected onto a screen coordinate system, and outputs the unit areas. A similar process is applied to second and subsequent unit figures so that the multiple unit areas constituting each unit figure are sequentially output. An area divider divides each of the unit areas sequentially output from the rasterizing unit into multiple subareas. An area discarder discards as necessary a subarea obtained by the division by the area divider according to a predetermined rule. An area writer re-merges subareas that survived the discarding process by the area discarder and writes merged areas obtained by re-merge in the memory.
