Abstract: A method of inspecting a quiescent power supply current in a semiconductor integrated circuit, includes an ID information acquisition process for acquiring ID information of the semiconductor integrated circuit, a quiescent power supply current measuring process for measuring the value of the quiescent power supply current in the semiconductor integrated circuit, a measurement information storing process for storing the quiescent power supply current value and the ID information in a corresponding manner, a reference value determining process for determining a reference value for the quiescent power supply current on the basis of the stored quiescent power supply current value, and a defect determining process for comparing the stored quiescent power supply current value with the reference value for the quiescent power supply current to determine whether the semiconductor integrated circuit is defective or not.

Abstract: An apparatus for expanding or contracting image data includes an input for storing the image data to be processed, a first barrel shifter for shifting the output data of the input register, a control register for storing a mapping pattern which indicates a position of the image data bits to be extracted in the expansion mode or which indicates the number of times when the image data are to be copied, an expansion and contraction circuit for expanding or contracting the image data by referring to the mapping pattern, and a second barrel register for shifting the output image data of the expansion and contraction circuit before the data are loaded in an output data register.

Abstract: An original image field is successively scanned along each of parallel line paths to detect the image density of the scanned elemental picture area. A plurality of recurring sequences of binary digits or pulses is generated for each of the scanned line paths in synchronism with the scansion of each elemental picture area, thereby forming dot pattern conversion matrices corresponding in number to the number of discrete gradation steps or image densities with the pulses representing the dots in each matrix. The detected image density is used to select a corresponding one of the dot pattern matrices to represent the scanned area with a dot if the latter is present in a specified position in the corresponding matrix by allowing the selected recurring pulse sequence to be delivered to a recording unit which is moved with respect to a recording field in synchronism with the scansion of the original field.
