Abstract: PROBLEM TO BE SOLVED: To provide a charger which can utilize natural energy effectively if there is sufficient capacity by the time when charging must be completed.SOLUTION: A completion time setting unit sets a completion time when charging of a secondary battery must be completed. An output current measuring unit acquires the output value of a current from a natural energy power supply device. An electric energy acquisition unit acquires an electric energy that must be supplied before completing the charging of the secondary battery. A prediction time calculation unit calculates the time, when charging of the secondary battery only with the natural energy power is completed, as a prediction time based on the output value and the electric energy. A control unit charges the secondary battery only with the natural energy power if the prediction time is earlier than the completion time.

Abstract: PROBLEM TO BE SOLVED: To extend a search range without increasing a transfer rate of retrieval data in the case of coding an image. SOLUTION: A motion detection circuit 3 outputs a motion vector (d) of a reference block and its residual (e) at that time from image data (a) of the reference block transferred from a reference frame memory 1 and from image data (b) of a check block transferred from a retrieval frame memory 2. A motion vector distribution detection circuit 4 decides a reference vector corresponding to a center of a search range in the case of detecting a motion between images apart by 2-frame/2-field or over based on a motion vector distribution between images apart by, e.g. 1-frame/or 1-field. Then the circuit 4 reads retrieval data in response to the reference vector corresponding to the center of the search range to output a control signal (c).

Abstract: PURPOSE: To reduce a circuit scale in a motion vector detection circuit for block matching. CONSTITUTION: Data in a reference block read out of reference frame memory 1 is quantized by a quantization circuit 5, and it is supplied to a motion detection circuit 7. Data in a retrieval block read out of retrieval frame memory 3 is quantized by a quantization circuit 6, and it is supplied to the motion detection circuit 7. The data of quantized reference block is compared with that of quantized retrieval block, and a motion vector is detected on the basis of the retrieval block with highest matching degree. Since the data of the reference block and that of the retrieval block are quantized and supplied to the motion detection circuit 7, the circuit scale is reduced.

Abstract: PURPOSE:To reduce an arithmetic amount by dividing a reference block and an inspective block into small blocks and detecting a motion vector with accuracy less than a 1/2 pixel while using residual calculated for each small block. CONSTITUTION:The pixel data of the reference block read out of a reference frame memory 1 and the pixel data of the inspective block read out of a retrieval frame memory 2 are respectively supplied to feature extraction circuits 5 and 6. A subtraction circuit 7 calculates the difference of feature extracted values between both blocks from the outputs of the circuits 5 and 6. An absolute value circuit 8 calculates the sum of the absolute value of the differential value of the feature extracted values and this value is stored in memory 9 as residual data. A minimum value detection circuit 10 calculates the minimum residual data. An interpolated residual estimation circuit 11 calculates the residual data at the position of the inspective block by interpolation. A minimum value detection circuit 12 calculates a reference value from the output of the circuit 11. Then, the motion vector is outputted from an adder circuit 13 with the 1/2 picture element accuracy.

Abstract: PROBLEM TO BE SOLVED: To enhance the image quality by setting properly a search range so as to predict a motion with high accuracy, even if a large motion takes place, a time change of a moving speed is irregular, acceleration, or deceleration takes place. SOLUTION: A stored retrieval field 102 in a memory 1 is given to a simple motion detection circuit 2. The simple motion detection circuit 2 outputs a movement amount 105 and is given to a control discrimination circuit 4. A motion detection circuit 3 receives a current frame 103 and a retrieval frame 104, to obtain a final motion vector 107 used actually for motion compensation. The control discrimination circuit 4 gives a setting parameter 106 for a search range depending on a predicted motion amount, by the simple moving vector 105 to the motion detection circuit 3, where the search range is set.

Abstract: PURPOSE:To form the motion vector detector in which sufficient performance is maintained and the circuit scale is reduced when plural motion vector detection units are arranged to extend the search area. CONSTITUTION:Plural sets of motion vector detection units for prescribed search areas 1-4 are provided to reserve a wide search area 10. A search area 5 for a motion vector detection unit is arranged to an area of the search area 10 in which the existence of a correct solution motion vector is highly possible with a deviation so that the number of search points is increased. Thus, the detection performance in the area where the existing of the correct solution vector is highly possible is enhanced.

Abstract: PURPOSE:To satisfactorily link images betweel frames by displaying plural frames at a certain frame interval larger than the number of those frames. CONSTITUTION:When the time for reading video data required for displaying N frames from a video disk 1 is equal to the time for displaying them, data read and display are thus executed. When this operation is completed, the device is turned to the state of reading the next data by driving a slide motor 5 or displacing an optical head 3. This access time is set shorter than a vertical blanking period. When the compressed data are recorded in the disk 1, the read time is shorter than the display time but at such a time, the rotating speed of the disk is set low. When the disk 1 recorded with the compressed data is reproduced, the read time is made shorter than the display time. At such a time, an access period from the end of reading to the next reading is made longer than the vertical blanking period, and it is possible to deal with the high-speed reproduction of a CLV disk as well without using any frame memory.
