摘要： PROBLEM TO BE SOLVED: To cancel inconveniences where image information and switch information are transmitted to a computer through independent systems. SOLUTION: An external interface 105 of an input device 101 embeds the state of a switch 104 in image data generated by a camera control part 103 and output it to an external part. An image-processing driver sub-routine 110 at the side of the computer change-over processings according to the switch state buried in image data. An application program 111 reads image data via an image input interface 109 and detects information of a camera side switch from a prescribed kind of pixel data.

摘要： PROBLEM TO BE SOLVED: To provide a video information input device capable of inputting various image information within a wide focal range from just closeness to a distance. SOLUTION: This device is provided with a camera part 10 which fetches external video through a lens 12 by using a CCD image pickup element, etc., a focussing ring 13 which can switch the focal distance of the lens 12 to each mode of a link stick mode for very closeness, a short-distance view mode in which the short-distance view of a near person, etc., is photographed and a long-distance view mode in which a landscape, etc., is photographed, a holding part 20 whose axis is connected integrally with the optical axis of the part 10 at an inclining attitude, a focal stick 30 that can be folded into the part 20 and an interface cable 50, performs fetching/image recognition of a still picture on paper 90 at the operation opportunity of a switch 40 by using the stick 30 in the link stick mode and folds the stick 30, switches the ring 13 and photographs short-distance view/long-distance view in the modes other than the link stick mode.

摘要： PROBLEM TO BE SOLVED: To solve the problem that it is difficult to allow a cursor to linearly step forward, and it is impossible to move the cursor to the destination in the shortest distance in an information processor having a display device and a pointing inputting device such as a mouse. SOLUTION: A direction inputted from a pointing device is detected, and the action point of a nearest object on the extended line is detected, and when the action point is detected, the detected action point is defined as a target, and a movement target line connecting the specified action point to cursor coordinates is calculated, and whether or not the cursor post-movement coordinates after the action point is specified are present within an error angle is decided, and when it is judged that the coordinates are present within the error angle, the cursor is displayed not at the coordinates following the inputted instruction but at the coordinates on the nearest movement target line, and when it is decided that the coordinates are present beyond the error angle, the cursor is displayed at the coordinates following the inputted instruction, and the setting of the error angle is cleared.

摘要： PURPOSE:To eliminate a waste of arithmetic operation so as to shorten a display processing time by processing a figure in a different system when the figure is displayed in a display region before and when the figure is decided not displayed. CONSTITUTION:When a figure is stored not displayed in a figure data memory means 27, a process for deciding whether an overlapping region is provided or not is performed by a figure data arithmetic means 28, and when the overlapping region is provided, a display process is performed. Here, whether the figure is actually displayed or not in a display region is stored in the memory means 27. Now, when the figure is stored displayed in the display region, a display in the preceding time is decided in the case of the next figure display process, so that the figure display process can be performed at a high speed. On the other hand, when the figure is stored displayed before, the display process and a memory process are performed without performing the process for deciding whether the overlapping region is provided or not.

摘要： PURPOSE:To obtain the display control unit which is inexpensive and small in size by holding the processing of received information until synchronization with VSYNC. CONSTITUTION:When drawing information transferred from FIFO(First-In, First-Out) 102 is VSYNC synchronization information, a decoder 104 sends a VSYNC synchronization information reception signal 108 to an FIFO readout control part 110. Then when drawing information which is not the VSYNC synchronization information is sent to the FIFO 102, the FIFO readout control part 110 does not transfer information to the decoder 104 until a VSYNC signal 113 is received even if a drawing information processing part 106 sends an FIFO readout request signal 109. Then when the FIFO readout control part 110 receives the VSYNC signal 113 from a VSYNC generation part 112, the transfer of information from the FIFO 102 to the decoder 104 is restarted. Further, the decoder 104 decides that the information is not the VSYNC synchronization information and the drawing information processing part 106 outputs the information.

摘要： PURPOSE:To specify only one defective VRAM when a test result is defective regardless of the constitution of a frame memory and to improve the test efficiency/precision of the frame memory by allocating coordinates to respective picture elements constituting a display screen and conducting the test for the arbitrary coordinate. CONSTITUTION:A serial data control part 304 compares the coordinate value of the picture element which is being read at present, namely, a value held in a coordinate counter 103 with the coordinate value of the picture element being a test object, which is written into a read coordinate register 102, in a comparator 104. Data of the picture element being the test object is stored in a data register 101, and data in the data register 101 in the serial data control part 304 is read. Then, data which is read is compared with data which is previously written into the RAM part of the frame memory for the test at first. When compared results are coincident with each other, VRAM is normal. When they are non-coincident with each other, it is abnormal. Then, defective VRAM can easily be specified.
