In an automatic recording mode, an action sensor 6 detects acceleration depending on motion of a user 9 in a three-dimensional space, displays the number of steps as computed on the basis of the detected acceleration on an LCD 35 as equipped therewith, and records it. In a manual recording mode, the action sensor 6 records behavior information and body information as inputted by the user 9. In a communication mode, the action sensor 6 transmits the information recorded in the automatic recording mode and the manual recording mode to a cartridge 4 while the cartridge 4 visualizes the information. In the communication mode, the action sensor 6 inputs the acceleration information to the cartridge 4 in real time, and provide the user 9 with various contents using a video image to be displayed on a television monitor 5 in cooperation with the cartridge 4.

An apparatus and method for generating a path using a limited memory size are provided. An approximate path is generated based on a reduced grid map generated by reducing an original grid map. Then, an approximate path is mapped onto the original grid map, and the mapped path is enlarged and divided into a plurality of sections based on an available memory size used for path calculation. Based on a start point and a destination point set in each of the divided sections, a detailed path in each of the sections is generated.

The present invention can realize better display of a dynamic image, and in addition, can make storage capacity of a memory smaller. A data conversion circuit 112 compares display data 102 of an n-th frame from the outside and display data 116 of the (n−1)-th frame stored in the memory 104, to generate a driving data signal 117 to deliver to a driver. Each time when a memory control circuit 103 reads display data q0, q5, q10, q15 corresponding to 20 pixels out of the display data 116 of the (n−1)-th frame, the memory control circuit 103 compresses display data d0–d19 of 20 pixels out of the display data 102 of the n-th frame from the outside to generated d0, d5, d10, d15, and stores the generated data into the same area where the display data q0, q5, q10, q15 of the display data of the (n−1)-th frame have been stored.

First, image data is converted using a first table storing conversion values in addresses corresponding to at least input values: u(k) represented by u(k)=ab^−k (where a and b are constants and k is 0, 1, 2, . . . m) of all input values and linear interpolation. Next, a second table storing conversion values set in response to the image data provided by conversion using the first table in addresses corresponding to at least input values: v(k) represented by v(k)=ck+d (where c and d constants and k is 0, 1, 2, . . . n) of all input values is stored in memory. Next, the image data provided by conversion using the first table is again converted using the second table and linear interpolation.

A disk player includes a system controller. The system controller creates marked-playback-start-position specifying data every time a user presses a playback position marking key of an operation unit to mark a playback start position. If the user presses a menu screen display key of the operation unit to instruct the display of a marked-playback-start-position selection-menu screen, the system controller displays an image corresponding to each playback start position on the marked start position menu screen. If title playback is stopped or paused, the system controller creates stop position specifying data for specifying a stop position and stores the data in a RAM. The system controller displays a stop position menu screen including stop-position-related information based on the stop position specifying data. If any of the stop-position-related information is selected, the system controller restarts the playback of images and sound from the corresponding stop position based on the stop position specifying data.

The CPU of a face orientation detection apparatus which acquires an image frame photographed by a camera through a cable detects the face region in the horizontal direction of the acquired image frame by executing computer programs stored on a hard disk. Moreover, the CPU detects the eye position in the vertical direction from the image frame, and detects the nose position in the horizontal direction based on the detected eye position. Furthermore, the CPU detects the orientation of the face included in the image frame, based on the detected nose position and face region.

A compiler has a detection unit, a conversion unit, and a expansion unit. The detection unit detects a predetermined target from an input source program. The conversion unit converts the target detected by the detection unit into a procedure call. The expansion unit generates an online code describing a definition of a procedure to be called by the procedure call obtained by the detection unit. The compiler outputs a program in which the target detected by the detection unit is replaced with a procedure call, and an online code corresponding to the procedure call.

In a reproducing apparatus capable of displaying text subtitles in synchronization with an AV stream, before the AV stream is reproduced, text subtitle streams and font information are read into a preload buffer section (122, 123) in a sequence determined by a priority language setting section (131), and subtitle images are generated from the text subtitle streams and font information and displayed overlaid on the image information of the AV stream. Even if a preload buffer section with a small memory size is used, when the text subtitle language is switched, the text subtitle display can be switched smoothly, with little likelihood of interrupting the audio-video display.

A fault diagnosis section activates a driving compornent alone, measures an operation state signal and a paper passage time, and stores feature values (Vm, σv, Tqs, σts) extracted as a determination reference in a storage medium. A paper passage fault determination section determines whether or not a fault has arisen on the basis of the paper passage time when an apparatus is under normal operating conditions. A diagnosis target block determination section determines an order to operate a detail fault diagnosis when it is determined that there is a plurality of diagnosis target blocks. When the driving compornent is activated alone under actual operation conditions, the operation state signal Vf is obtained, and an operation state fault determination section conducts diagnosis on whether or not a fault has arisen on the driving compornent and a state of the fault, and whether or not a fault has arisen on other power transmission compornents and a nature of the fault with reference to the feature values as the determination reference on the basis of a degree of deviation from a normal range.

According to the cell broadcast information (especially regional information) accumulated in the “cell broadcast information accumulation section”, the “location judgment section” judges the address of the area where the mobile terminal existed (that is, where the user was present) at the aforementioned reception date and time.

It is expected to increase the size of a display panel and the number of tones to be displayed on the display panel, and it is requested to use a display panel displaying M (M>3) types of colors. This requires a large memory capacity and makes a circuit for performing signal conversion complex due to an increase in the amount of data to be subjected to the signal conversion. An image memory stores image data compressed at a fixed compression rate, and the signal conversion is performed on the compressed image data. This technique reduces a memory capacity and simplifies a signal conversion circuit. The signal conversion makes it possible to improve color reproducibility of an image displayed and the quality of the image due to smoothing of the outline of the image. In the case of a display panel having sub-pixels displaying M types of colors, the signal conversion is performed on a compressed signal for each sub-pixel to improve the quality of an image.
