Inventor: SHIMIZU TETSUYA CANON KABUSHIK
IPC: H04N5/92
Filed: 1991-05-31
Abstract: A digitally coded signal is encoded with an error correction code and an error detection code. When the signal is decoded, the error correction code is used to correct errors. The error detection code is then used to discriminate whether the error correction process has operated properly, and if it has not operated properly then interpolation is used to avoid remaining errors. Preferably when the data is encoded the error detection code is provided before the error correction code is provided.

The provision of parallel data paths having a small number of gates therein enables high-speed flip-flop operation to be achieved. A clock generating circuit (230) which may be selectively enabled generates true and complementary clock signals for the flip-flop circuit (200). In a modification, provision is made for a RESET signal to reset the flip-flop circuit (200).

Abstract: According to the invention, to make the reading operation of an eyesight handicapped person easy, the result of the image pickup of a camera unit to photoelectrically convert the character information is displayed by a pin pattern on a display. When the operator detects the character area from the display result, an area of an object for character recognition for the result of the image pickup is designated by an input unit and the execution of the character recognition is instructed. A processor recognizes the character with respect to the result of the image pickup of the designated area and displays the character so that it can be perceived in a tactile manner. Whether the result of the reading of the character is correct or not can be checked by a tactile perception. The recognition result of the character recognized can be generated by an audio output by an audio output unit.

Abstract: A light valve such as an active matrix LCD between crossed polarizers, utilizing, for instance, individual transistors to control each "pixel area" of the LCD and storage elements to store video signal data for each pixel, with optically shielded "dead spaces" between pixels to eliminate electric field crosstalk and non-information-bearing light bleed through, is illuminated with a bright independent light source which creates a video image projected via specialized projection optics onto an internal or external screen without distortions, regardless of the angle of projection onto the screen. Use of heat sinks, IR reflective coatings, heat absorbing optics, optional fluid and a thermistor controlled pixel transistor bias voltage injection servo circuit stabilizes image performance, maintaining accurate color and contrast levels as the LCD changes temperature. In one embodiment of the invention, use of a multi-color LCD with a stepped cavity, producing different thicknesses of LCD for the different wavelengths that pass through it, allows a linear correspondence between the wavelengths passing through the LCD to produce true black, high contrast and CRT-like color rendition. A dichroic mirror arrangement is used to overlap differently colored pixels in the projected image. Use of striped mirrors duplicate pixels, where necessary, eliminating spaces between pixels, creating a continuous image with no apparent stripes or dots. A special venetian-blind type of screen is also disclosed and methods for using the system to view three-dimensional video are also explained.

Abstract: In an image processing system for performing parallel processing for each pixel by line parallel local computation an endless type slit memory (4) of finite length capable of storing as much data as required in a row, in which a terminal address is connected to a top address, is addressed by a base pointer (1) and a reference pointer (2). Each time the line is changed, the content of the base pointer is changed one by one by an external controller (50), and it is cleared to a top address after a terminal address, the content of the base pointer is written in the reference point at the same time, and the address of the slit memory (4) is specified by the reference pointer (2) and the content of the reference pointer is changed by one at the same time, and a region of the slit memory corresponding to the mask size of a filter is sequentially accessed by the reference pointer. 
     In a novel filtering method for such system using a filter having weight with left-to-right symmetry, each processing element (PE) multiplies the pixel data of a row, for which it is in charge of processing, by the weight of the central row of a filter and the results are added, and the pixel data of a row, for which it is in charge of processing, is multiplied by the weight of the other rows on one side of the central row of the filter and the results are added. Each element receives the results of computation maintained by the processing elements of the other rows by transfer and executes a filtering operation.

Abstract: A method for processing signals to diffuse quantization error spatially or temporally. Positive feedback of the quantization error is used to reduce the relative noise for the low frequencies of the spectrum. According to a preferred implementation in a two-dimensional spatial application involving a base pixel and three adjacent orthogonally arranged pixels, error attributable to quantization at the base pixel location is provided as positive feedback for the quantization of the diagonally adjacent pixel. Offsetting and complementary values of the quantization error are also diffused to the remaining two diagonally positioned pixels. The composite of the four pixels forms a square with a zero net error diffusion along the horizontal, vertical and diagonal orientations.

Abstract: A developing device has a brush-like toner carrying roller for carrying charged toner and a toner supply roller which is in contact with the toner carrying roller and charges the toner by friction, and applies a voltage having the same polarity as the charging polarity of the toner to the toner supply roller. With this arrangement, since the charged toner and the toner supply roller produce repulsion therebetween, it is possible to carry a sufficient amount of toner on the surface of the toner carrying roller. Therefore, even when the electric field strength is weak, it is possible to cause a sufficient amount of toner to fly from the surface of the toner carrying roller. Consequently, a quality image can be stably produced with an inexpensive small-size structure. Moreover, by moving the toner carrying roller to a position where it comes into contact with a grid electrode and cleaning the grid electrode with the rotating toner carrying roller, it is possible to prevent a lowering of the image quality due to adhesion of the toner to the grid electrode.
