An image composition method comprises: subjecting a first high-sensitivity image signal generated based on high-sensitivity image outputs from corresponding ones of a plurality of pixel positions in a solid-state imaging element that has imaged a subject, to a first nonlinear conversion, so as to prepare a second high-sensitivity image signal; subjecting a first low-sensitivity image signal generated based on low-sensitivity image outputs from corresponding ones of the plurality of pixel positions, to a second nonlinear conversion, so as to prepare a second low-sensitivity image signal; and subjecting the second high-sensitivity image signal and the second low-sensitivity image signal to weight adding at every common pixel position, over the entire range of an incident light exposure level exhibited by each incident light that entered to each of the plurality of pixel positions, so as to produce a composed image signal of the subject.

In an encoding apparatus or method, variable-length encoding data is packetized by a packetizing format in which a header of a packet has an area for indicating a packet length and the range of values indicating the packet length is limited. Variable-length encoding data is input and the data length of the variable-length encoding data is detected. According to the detection result, the input variable-length encoding data is packetized within the packet-length maximum value which can be specified in the header.

A recording and reproducing area and a reproduction-only area are formed by wobbling a groove formed in a spiral fashion to form a track to be tracked on a disk. The recording and reproducing area has address information recorded by wobbling of the groove and information recorded and reproduced by phase change marks on the track formed by the groove where the address information is recorded. The reproduction-only area has prerecorded information recorded by wobbling of the groove.

An image processing apparatus stores image data according to color constituent, sets an order of correction value data to correct input image data for each color constituent according to a command that specifies an output order of the color constituents, performs color correction in a color correction operation circuit using the specified correction value data, and outputs the image data. Without an output order change circuit, it is possible to perform the color correction and output image data of the color constituents according to an output device, resulting in a compact apparatus.

The invention relates to laser ranging technology, and provides a laser phase ranging module, including a laser emitting component, an echo receiving and preprocessing component, a local receiving and preprocessing component, and an FPGA processor; the FPGA processor uses a phase-locked loop to generate two Two clock frequencies f1 and f2 are divided by the clock frequency f1 to generate a square wave signal with a measuring ruler frequency fs and send it to the laser emitting component; the laser emitting component emits laser light to the target; the echo reflected by the target is received and preprocessed After processing, the component outputs a square wave A with a frequency of fs; the local receiving and preprocessing component imports the emitted laser part, and performs the same preprocessing on the imported laser as the echo receiving and preprocessing component to output square wave B; the FPGA processor uses a clock The frequency f2 reads the two square waves A and B synchronously, and calculates the target distance through data processing. The invention does not need frequency mixing processing, can realize long-distance precision distance measurement by using a measuring ruler, and is suitable for single-point distance measurement and multi-channel simultaneous distance measurement equipment.

This is oil collector used of the testing platform of injection pump. On this oil collector is installed oil injection sensor. This sensor is not only to ensure every oil cylinder is whether not inject oil but also can to survey every oil cylinder injective moment (or phase angle), then to calculate dynamic injective phase angle. As only to differentiate in the collector is whether not injection, so the sensor's linear degree can be lower, and its construction is simple. The output signals of this sensor are switched signals using to show the injection or not injection, so its resist disturbed ability is strong.

The invention relates to a force balance type transmitter of a strain type displacement detecting element, belonging to the technical field of automatic detection. At present, during the detection process of flow rate and liquid level, the widely used displacement detecting element of the force balance type transmitter is inductance output, thus the circuit of the transmitter is more complex, andthe adjustment is more troublesome. According to the invention, the strain type displacement detecting element is used for the force balance type transmitter, and the displacement detecting element is resistance output, the circuit of the transmitter is more simple, the adjustment is easier, the whole structure of the transmitter is a negative feedback closed-loop system, and is composed of a lever system, a displacement detecting amplifier of a forward channel and an electromagnetic feedback device of a feedback channel; and when the amplification factor of the displacement detecting amplifier of the forward channel is greater enough, the whole property of the transmitter depends on the lever system with more stable link property and the electromagnetic feedback device of the feedback channel, and has nothing relationship with the stability of the displacement detecting amplifier, thus the cost performance of the force balance type transmitter of the strain type displacement detecting element is relatively higher.
