Abstract: A test pattern P3 longer than a length Ld corresponding to a circumferential length of a developing roller is formed along a moving direction of a photosensitive member (or developing roller). The developing roller transports a great quantity of toner on its surface in a first revolution thereof and hence, the test pattern has a high density. When the residual toner runs low, the toner transport quantity is decreased in the subsequent revolution, so that the test pattern P3 is decreased in the density at its portion beyond the length Ld from its head. If a density difference is observed at place corresponding to a boundary between image portions formed in the first revolution and the second revolution, it is concluded that image quality is degraded due to the shortage of residual toner.

Abstract: An image processing apparatus includes a CPU and an imaging unit. In this image processing apparatus, an image captured by the imaging unit is displayed on an LCD together with an imaging index, indicative of a predetermined region of a face. In response to a shutter operation by an operator, a portion, matching with a position of the imaging index, is extracted from the image data as a region image. Furthermore, in response to a shutter operation, another image captured by the imaging unit is stored as a still image. Then the region image and the still image are composed with each other to display a composite image, obtained by pasting the image of the predetermined region of the face on to another image. In addition, with respect to the composite image, the region image is deformed according to a feature of the data from the imaging unit, an elapsed time without an operation input, and so on.

Abstract: The game apparatus shoots a moving object from a predetermined weapon object and moves the moving object in a three-dimensional space in a case where an input from an input device is received. At least one of the size, the shape, and the number of a contact determination area defined for the moving object is changed in accordance with a distance over which the moving object moves in the three-dimensional space. The game apparatus determines whether or not the contact determination area defined for the moving object contacts a contact determination area defined for a target object. A predetermined game process is performed when the determination result of a contact determination step is positive.

Abstract: At least one of continuous disconnection, intermittent disconnection, and temporary disconnection, of wireless communication between the input device and the game apparatus is detected. Remaining battery amount data representing a remaining battery amount of the input device is obtained via the wireless communication. It is determined that the power of the input device is insufficient based on that the wireless communication is detected to be disconnected and that the obtained remaining battery amount data represents a remaining battery amount of a predetermined level or lower. When it is determined that the power is insufficient, the power insufficiency is notified.

Abstract: A puzzle image to be solved, and a duplicating block for creating a duplicate character as a copy of a player character are displayed. The duplicate character is, on the basis of at least a fact that the player character is superposed on the duplicating block, generated in the superposed position. A time limit is set for displaying the duplicate character. Then, when a formation or an arrangement pattern formed by the generated duplicate character and the player character satisfies a predetermined condition indicated by the puzzle image, a change, such as displaying an image of movement of a block or opening of a door, for example, is applied to progress of the game.
