Title: Time width detection circuit and control method therefor
Inventor: LI SHUJIA
IPC: H02M3/158
Filed: 2019-01-07
Abstract: A time width detection circuit and a control method therefor. By means of sampling a signal satisfying timing logic and according to the time width thereof, a corresponding output signal is output. The circuit can be used in switched-mode power supplies and is used in conjunction with a drive regulation circuit that processes drive waveforms to control the drive signal input by a drive circuit. When an input signal Vin is a timing logic signal and the time it remains so does not surpass a set time, the voltage of the charging end of a capacitor C1 will be less than a determination value, and the output end of an output circuit will be suspended, thus not affecting the normal function of the drive regulation circuit. When the input signal Vin is a timing logic signal and the charging time exceeds the set time, the voltage of the charging end of the capacitor C1 will be higher than the determination value, and the output circuit will output a low level signal, shutting off the output signal from the drive regulation circuit. The determination value of the voltage of the charging end of the capacitor C1 is adjustable, and the set time is also adjustable. The present circuit experiences little loss, is low cost, and does not burden normal circuit design.

Abstract: The present invention relates to a system and method for effectively representing and coding an image, and in particular, to processing for an image depth map. In the present invention, a block of an image is initialized before the image is segmented; a depth map block is partitioned or segmented; boundary and block approximation is performed on the partitioned or segmented depth map block; the steps of partitioning or segmenting the depth map block and performing boundary and block approximation on the depth map block are repeated until the maximum number of segmentation levels is reached; and the image subjected to boundary and block approximation is compressed to obtain a compressed image. According to the present invention, a parametric model (such as a polynomial) is used to model a pixel, instead of approximating a pixel value as a constant of an entire partition. Greater flexibility in required compression quality is provided for modeling depending on different types of image blocks. Therefore, by means of the provided method, a complex structure can be approximated more accurately, thereby achieving better compression quality. In order to further improve the compressibility, hierarchical clustering is applied for partitioning. Therefore, partitions have a more compact representation pattern, so that the data volume after compression is reduced.
