Abstract: A peripheral device acquires the processing load of a display apparatus to which the peripheral device is connected via an interface. In accordance with the processing load acquired, the peripheral device generates a data command for adjusting the load of processing for rendering display data. The display apparatus alters the display data based upon the data command, renders the display data after the alteration thereof and displays the rendered data. As a result, when the peripheral device instructs the display apparatus to subject the display data to rendering process, an increase in length of time it takes to obtain the result of rendering is reduced.

Abstract: The invention provides an image encoding apparatus which can improve image quality of an output image while further reduce the amount of attribute. A determination unit determines an area including a character/line drawing as a foreground image area based on an input multi-valued image. A foreground image generator generates foreground image in binary representation so that a first encoder performs MMR encoding on the foreground image. A background image generator generates multi-valued background image data by replacing the value of a multi-valued pixel in a position of the character/line drawing in the foreground image area with a replacement value calculated from the pixel values in a position of the non-character/line drawing pixel. A second encoder performs JPEG encoding on the background image. A mask unit masks attribute for pixels within the foreground image area with a predetermined value to output the masked data to a third encoder.

Abstract: An image projection apparatus in which a measuring unit measures a distance from the image projection apparatus to a projection surface. A generating unit generates a first operation image if the measured distance is less than a threshold value and generates a second operation image if the measured distance is not less than the threshold value.

The second operation image is an image by which an operation can be input by operating a cursor displayed in the second operation image that is being projected using a predetermined operating unit. A projecting unit projects an operation image generated by the generating unit onto the projection surface.

Abstract: A collision target map and a collision target LUT are generated for each pixel to be subjected to rendering as collision target information with recorded identification information for CG data rendering on the pixel, while carrying out rendering of colliding object group CG data. Then, collision target information corresponding to a rendering pixel is referenced while carrying out rendering of collided object group CG data. In a case in which the colliding object group CG data is contained in the collision target information, it is determined that collision detection should be carried out for a virtual object being rendered, and collision detection information is generated. Such collision detection information allows collision between virtual objects to be detected at high speed.
