Title: Image compression restoration process
Inventor: HERLEY CORMAC
IPC: H04N7/26
Filed: 1998-06-15
Abstract: PROBLEM TO BE SOLVED: To reduce distortion due to compression with a loss in the image compression and restoration. SOLUTION: In an interpolation image compression restoration device 600 executing reduction in image compression archifact, a compression interpolation input image 610 is compressed and restored by a compression restoration unit 620 and stored in a non-compression image storage device 630 and fed to an interpolation projector 640 finding out a closest image interpolated by the known method. A comparator 670 compares an interpolation image from the interpolation projector 640 with a closest image compressed to a same compression output as the original image from the compression projector 660. In the case that the two images are closer to each other sufficiently or no more improvement is attained, the comparator 670 releases the interpolation image stored in an interpolation image storage device 650 as a non-compression output image 680.

Title: Coated metal plate for electrostatic recording
Inventor: SATO MASAKI
IPC: G03G5/02
Filed: 1994-06-27
Abstract: PURPOSE:To obtain a coated metal plate on which an image can be directly recorded by specifying the surface specific resistance of a conductive layer and the volume resistivity of a dielectric layer. CONSTITUTION:In this coated metal plate, an insulating layer, conductive layer and a dielectric layer are successively formed from the plate side on the metal plate. The surface specific resistance of the conductive layer is 1X10<6> to 1X10<9>OMEGA and the volume resistivity of the dielectric layer is >=1X10<12>OMEGAcm. If the surface specific resistance of the conductive layer is <1X10<6>OMEGA, the selected controlling electrode substantially makes a short circuit with a recording electrode on a non-controlling electrode in the both sides through the conductive layer, which produces a ghost image or makes recording impossible. On the other hand, if the surface specific resistance exceeds 1X10<9>OMEGA, enough discharge is not obtd. in 5-10mus recording pulse time, which makes recording impossible. The dielectric layer is used to hold an electrostatic latent image so that the layer is required to have enough electrostatic charges on the surface to attract a toner to obtain enough recording density during developing. Thereby, a synthetic resin having high insulating property is used.

That is, by differentiating the pulsation component two times, the acceleration component is extracted. From the acceleration component extracted in such a way, a feature of a waveform of the acceleration component is classified by a section classifying method, and by comparing its result with a result of classification obtained by a clinical test, the quality of a peripheral blood circulation function is decided.

Abstract: PURPOSE:To prevent the deterioration of a picture quality by calculating a data amount after encoding when quantizing an orthogonal component obtained by an orthogonal transforming means by the plural kinds of quantizers corresponding to the component, and selecting the optimal quantizer for each small block by using the data amount. CONSTITUTION:A variable length code whose code length is one bit when a quantized value is '0', is used. That is, when a certain quantized value Ri equals '0', a code length Ni equals 1. Thus, the number of the quantized values to be transmitted and the 6 bit coordinate of the top of a rectangle are added to the sum of every quantized value of one small block and (Ni-1), in order to calculate the data amount. Then, the quantizer is decided by a small block unit so that the data amount is not beyond the transmission data amount decided preliminarily by a large block. Then, the data amount is variable-length encoded by a variable length encoding means 16, and outputted to a transmitting means 17. Therefore, the control of the data amount can be certainly operated so that the variable length encoding whose code length is constant in a small range can be realized.
