Title: Dot area decision device
Inventor: HAYASHI SHINJI
IPC: G06T7/00
Filed: 1994-11-16
Abstract: PURPOSE: To surely detect a peak/dip picture element regardless of high or low gradation in the dot area by deciding the dot area while taking notice of the peak picture element or the dip picture element depending on the degree of gradation of an image area. CONSTITUTION: A three-primary color signal is subjected to correction processing by an input processing circuit 2 and stored in an FIFO memory 3 and only information by a prescribed line selected for deciding the kind of source document is transferred to a character/dot/photograph decision circuit 4. The circuit 4 averages the density of a noted picture element and the density of surrounding picture elements and compares the average value with a prescribed threshold value to detect a peak/dip picture element. Which of the peak or dip picture element is adopted for the decision is decided based on the result of decision of high gradation, low gradation and intermediate tone. Then the peak picture element is taken notice and an area is discriminated to be a dot area when the number of peaks in a block is larger than the prescribed one.

IPC: G01R31/28
Filed: 1990-10-22
Abstract: PURPOSE:To improve efficiency in testing of a logic gate by providing a logic gate data selection circuit which is controlled by an externally provided logic gate data selection signal. CONSTITUTION:At the time of operation test of a logic gate 2 first, a data selection signal SEL is set to an 'L' level whereby data selection circuits 14 to 16 set the following. That is, input signals 11 to 13 are coupled to data input terminals TG1 to TG3 of the gate 2 respectively and input as test input data G1 to G3. In this case since the signals 11 to 13 to the gate 2 are directly input from input terminals T11 to T13 to the terminals TG1 to TG3 of the gate 2, required test can be performed per cycle irrespective of write/read of a memory unit 1. Then during normal use, the signal SEL is set to an 'H' level and settings of the circuits 14 to 16 are made. These are equivalent circuits to conventional ones. With respect to operation in this case, the operation is exactly equal to that of the conventional ones.
