摘要： A portable device includes an acceleration sensor capable of detecting accelerations in three-axis directions. When a GPS radio wave is receivable by a GPS module, the portable device stores, using an MCU, a correlation between a body vibration frequency detected by the acceleration sensor and speed information grasped by processing a signal included in the GPS radio wave in a flash ROM. When a reception state of the GPS radio wave does not satisfy a predetermined standard, the portable device estimates running speed using the MCU on the basis of the body vibration frequency detected by the acceleration sensor 38 and the correlation stored in the flash ROM.

摘要： PROBLEM TO BE SOLVED: To obtain an image falsification detection system for a digital camera that applies image processing to the recorded image data. SOLUTION: In the case of installing a watermark program, a program to limit image processing to a recorded image is installed at the same time. When a user is going to execute image processing, the program to limit image processing is executed and displays a fact of inhibited image processing on an LCD 19. Or whether an image is a recorded image by the watermark program or an image normally recorded is discriminated depending on a header added to the image data and the image processing may be inhibited only in the case of the image recorded by the watermark program. Thus, the revision of the image data recorded by the watermark program and the lost of the electronic watermark is prevented.

SOLUTION: The method for extending the image comprises the steps of: recovering the predetermined number of digitized representative values of the DCT coefficients at each block in a zigzag sequence by using a code table (steps S210 and S215), setting the residue of the digitized representative value of the DCT coefficient at each block to '0' (step S220), inverse digitizing the digitized representative value, recovering the DCT coefficient, inverse discrete cosine transforming (IDCT) the DCT coefficient at each block, and recovering the image data.

摘要： PROBLEM TO BE SOLVED: To provide a digital camera by which an image is printed at high speed in the case of direct printing. SOLUTION: Gradation data in the row direction of a certain color in image data includes a sequence '140, 32, 45, 208,...'. When it is magnified by two and half times in accordance with a printing size, an extension table where the sequence '2, 3, 2, 3,...' is recorded corresponding to the coordinates of image data is used, a repetition number is added to gradation data of each pixel in image data corresponding to the coordinates and extension data '140, 2, 32, 3, 45, 2, 208, 3,...' are generated and stored in a RAM. Then a processing is executed at high speed with a reduced RAM capacity to be used compared with a case where the number of gradation data of each pixel in image data is increased for the portion of magnifying power.

摘要： PROBLEM TO BE SOLVED: To provide an audio data processor in which the load on a CPU (1st arithmetic processor), when audio data are processed, is reduced. SOLUTION: The audio data processor is an audio data processor, having a 1st arithmetic processor and a 2nd arithmetic processor. The 1st arithmetic processor has an audio data acquiring means of acquiring audio data as digital data and a transmitting means of excluding bits corresponding to low sound volume which humans have difficulty hearing, from the audio data and transmitting the resulting data to the 2nd arithmetic processor. The 2nd arithmetic processor has a receiving means of receiving the audio data sent from the 1st arithmetic processor and a reproduced data generating means of generating the audio reproduced data needed to reproduce the audio data, based on the audio data received.

摘要： PROBLEM TO BE SOLVED: To allow a system to confirm whether or not image data have been altered from image data at photographing. SOLUTION: An electric signal outputted from a CCD is converted into a digital signal in a step S11. Digital data outputted from an A/D converter are stored in a RAM in a step S12. Various image corrections are applied to the data stored in the RAM in a step S13. The data corrected in the step S13 are compressed by the JPEG system in a step S14. Error detection data are generated from the compressed image data in a step S15. Error detection data are encrypted in a step S16 to obtain encrypted data. The image data and the encrypted data are stored in a flash memory as a JPEG file, in cross reference with each other in a step S17.
