摘要： The least significant bits of respective count values of an H counter and a V counter are combined, to generate a timing signal defining a 2×2-size repeat block. A timing register including four registers each storing data which determines a color of each location within the repeat block is provided for each of input channels. A selector selects one of outputs of the timing registers based on the timing signal, and generates a signal designating a color of a pixel at a certain time for each of the input channels. A register storing black level correction data for each color is used in common by the input channels. For each of the input channels, an item of black level correction data at the certain time is selected based on the signal designating the color of the pixel at the certain time and input to a pre-processing circuit in each of the input channels.

摘要： Two local buffers are provided between an image processing unit and an image compression and expansion unit for compression into a predetermined format. Write and read control units serve to alternately use the two local buffers. As a result, process flow starting from the image processing unit to generate compressed image data by the image compression and expansion unit requires no main memory, whereby high-speed image processing is allowed with low power consumption.

摘要： First pixel data of a pixel of interest is output from a first shift register, while second and third pixel data of neighboring pixels indicative of the same color are output from second and third shift registers, respectively. Differential data between estimated pixel data calculated from the second and third pixel data and the first pixel data is input to a comparator. A threshold value stored in a register is modulated by the estimated pixel data, and is input to the comparator as modulated threshold data. When the comparator judges that the differential data is greater than the modulated threshold data, a selector outputs the estimated pixel data as corrected pixel data.

摘要： RGB image data outputted from an ADC (3) is processed in an SPU (42) and an RPU (43) and then buffered into a memory (48) as YUV image data. The YUV image data is outputted from a YUV output unit (45), encoded by an image compression and expansion chip (5A) and transmitted to a main chip (4) by a DMAC (52). On the other hand, compressed moving image data stored in the memory (48) is transmitted to the image compression and expansion chip (5A) through the control by a DMAC (44), decoded therein, then converted into RGB image data in an RGB sampling unit (54) and inputted to the main chip (4) by the SPU (42) through a data line (14). With such a construction, it is possible to provide a circuit for compression and expansion, which allows connection with a main processing chip having no YUV input circuit without increasing circuit scale, maintaining general versatility of those circuits.

Next, the CPU performs a control for photographing the main subject in presence of the auxiliary light, whereby an image signal is outputted from the analogue signal processing section. An AF area extracting section extracts image signals in an AF area from the image signals. A differential signal calculating section outputs a differential signal between the extracted image signal, and a distance measuring section compares magnitudes of that differential signal and a reference value in a distance data base to calculate distance information based on the comparison result. An AF control section executes AF control of mountain climbing system with the use of the distance information.

摘要： A lock structure of a spherical bearing restrains an outer race from turning relative to a housing with a simple structure. It is provided with protruding portions formed on a periphery of one side of a bearing hole of the housing. A flange is formed on one side of the outer race. Meanwhile notches (engagement portions) are formed in the flange, which are brought into engagement with the protruding portions. An annular V-shaped groove (staking groove) formed in the other side of the outer race is staked. With such a simplified structure, the spherical bearing can be locked to the housing while being restrained from turning relative thereto.

摘要： On the periphery surface of the outer race, the stepped portion is formed, and on one side of the race retention hole formed on the housing, a screw portion is provided coaxially with the race retention hole, in which the setscrew is screwed and tightened. Retention of the front surface of the setscrew makes the end face of the stepped portion, pressed against the snap ring retained with the annular groove, formed on the race retention hole. Since the outer race is clamped by the setscrew and the snap ring and the gap between the end face of the outer race and the setscrew, and the snap ring becomes null, the outer race is securely retained in the axial direction.
