Abstract: A game machine executes a game in which a user character operated by a user, and a teammate character and an opponent character operated by a computer, act in a game space. A first determination unit determines whether or not the teammate character is performing a predetermined action. A second determination unit determines whether or not the user performs a predetermined operation indicating that the user has noticed the teammate character performing the predetermined action. An action control unit has the opponent character perform an action determined based on the predetermined action of the teammate character, based on the result of determination by the second determination unit.

Abstract: To provide a game device having a character transformation function and in which prevention of unnatural display of change of posture and facial expression of a character object is realized while suppressing increase in an amount of data and an amount of work related to motion data. In the present invention, a skeleton part (joint or bone) which is set for a character object placed in a virtual three-dimensional space is rotated so that a position of a predetermined vertex of the character object changes from a first position to a second position. In the present invention, a player is guided to change at least one of the first position and the second position.

Abstract: A display control section (72) controls a display unit to display an image on which a first axis corresponding to first information about a situation of a game and a second axis corresponding to second information about a situation of the game are set. A receiving section (74) receives an operation for specifying a position or an area in the image. A first condition relating to the first information and a second condition relating to the second information are acquired based on the results of reception by the receiving section (74). A game-character control section (84) controls the action of the at least one game character in a case where the results of determinations of whether or not the first information and the second information about the current situations of the game respectively satisfy the first condition and the second condition are predetermined results.

Abstract: To provide an image processing device capable of attaining shade expression on a surface of an object while reducing image processing load, and of reducing a sense of discomfort which the user may feel. A shading process execution unit (62) executes a shading process on the surface of the object, based on a pseudo-normal vector for each pixel of a texture image to be mapped onto the surface of the object. A shading process execution restraining unit (66) restrains execution of the shading process by the shading process execution unit (62), based on the distance from a viewpoint to the object. A pseudo-normal vector obtaining unit (60) stores information correlating the distance from the viewpoint with pseudo-normal vector information for obtaining a pseudo-normal vector of each pixel. Then, the pseudo-normal vector obtaining unit (60) obtains a pseudo-normal vector of each pixel, based on the pseudo-normal vector information correlated to the distance from the viewpoint to the object.

Abstract: To provide a game device capable of expressing, through a relatively simple process, a picture showing a first character object grabbing and pulling a clothing object of a second character object. According to the present invention, a direction from the position of the second character object to the position of the first character object is obtained, and based on the obtained direction, the positions of at least some of the vertexes of the clothing object are changed (S205). Further, the position of a predetermined portion of the first character object, which is used to pull the clothing object, is changed, based on the obtained direction (S206).

Abstract: To provide an image processing device capable of preferably producing a picture in which the shade expressed on a surface of an object will change according to change in the posture of the object. A pseudo-normal vector information storage unit (60a) stores a posture condition concerning a posture of the object and pseudo-normal vector information for obtaining a pseudo-normal vector for each pixel of a texture image to be mapped onto a surface of the object, so as to be correlated to each other. A pseudo-normal vector obtaining unit (64) obtains a pseudo-normal vector for each pixel of the above described texture image, based on the pseudo-normal vector information stored in the pseudo-normal vector information storage unit (60a) so as to be correlated to the posture condition satisfied by the posture of the object. A shading process execution unit (66) executes a shading process for the surface of the object, based on the pseudo-normal vector obtained by the pseudo-normal vector obtaining unit (64).

Abstract: To provide an image processing apparatus that enables display of a situation where all or a part of a display image changes using simple image processing. A first texture image, a second texture image, display priority of each pixel constituting the first texture image and a threshold value of the display priority are stored in advance. The second texture image is drawn on a predetermined polygon (S205), and the first texture image is further drawn thereon in accordance with the result of comparison between the display priority and the threshold value (S206).

Abstract: A method and apparatus for a game that makes it possible to freely establish a region by expanding or contracting various regions relating to a game with a simple operation. If a closed region for expansion or contraction is moved to a position adjacent to an already established expansion or contraction object region, and an expansion operation performed in a state where a boundary of the closed region for expansion or contraction and a boundary of the object region, the closed region for expansion or contraction is added to the original object region to enlarge the area of the object region. Thus, the boundary displayed overlapping on the object region and the closed region for expansion or contraction are removed, and a single linked boundary is formed on the new object region.

Abstract: When a character having a reflection portion in which a background image is reflected is displayed together with the background, a highly real display can be achieved without creating an excessive load o the image processing apparatus. That is, sub-part images extracted from a part of the background is pasted on respective sub-reflection portions, and such a character image is displayed together with the background scene.
