Title: Integrating circuit
Inventor: MIYAKE TOSHIHIDE
IPC: G03B7/083
Filed: 1988-03-19
Abstract: PURPOSE:To prevent the generation of an error in integration time by a charge transfer, etc., with an integrating circuit, etc., for controlling the exposure of a camera by maintaining a charging means at a ground potential and preventing the back flow from an accumulating means to the charging means by a switching means. CONSTITUTION:The integrating capacitor C of the accumulating means is charged by the constant current through a Miller circuit 3 and a transistor (TR)Q5 of a constant current source of the charging means when a switch S turns off cooperatively with a shutter. The output voltage of an operational amplifier 7 inverts to an L and a TRQ7 turns off to open the shutter by means of a magnet coil 5 when the output voltage of an operational amplifier 8 attains a reference value. The photocurrent of a photodiode D which receives the incident light charges the capacitor C. The TRs Q3, 4 are respectively turned on and off by the amplifier 7 at this time, by which the circuit 3 is disabled and the capacitor C is simultaneously maintained at the ground potential by the TRQ4 and the back flow to the capacitor C by the TRQ5 is prevented. The charge transfer by an electrostatic capacity system is thus obviated and the generation of the error in the integration time when the shutter is closed is prevented.

Title: Image reader
IPC: G06T1/00
Filed: 1992-03-24
Abstract: PURPOSE:To convert an original image which does not require a high quantization precision to the image data of gradient corresponding to the required quantization precision and to process the image by providing a gradient discriminating means and a gradient changing means which changes the quantization gradient of image data based on the discrimination result of the gradient discriminating means. CONSTITUTION:If image data inputted by an input part 10 are read in the stage of reading of a density band, the data are collected at every line as a unit by an input control part 20 and transferred to a data processing part 70. Transferred image data are analyzed by a density distribution analyzing part 71 to calculate a density distribution parameter. The parameter is stored in an external memory part 50 and used at the time of storing image data in an internal storage device. Though the memory circuit of the internal storage device can handle the image data up to the maximum of 8 bits per picture element, the image data of four bits are stored per picture element without damaging the image quality of the recorded picture when the gradient up to 8 bits is unnecessary.
