摘要： An image processing apparatus includes an image forming device, a reading device, and circuitry. The image forming device is configured to form a first pattern on a recording medium. The first pattern includes a plurality of patches in a plurality of tones. The reading device is configured to read the first pattern. The circuitry is configured to acquire read data of the first pattern from the reading device. The read data includes red, green, and blue (RGB) color space values. The circuitry is further configured to: correct the read data based on information indicating a relationship between a color and a position in the first pattern to reduce variation in readings due to a read position of the first pattern; convert the read data corrected into device-independent data; and adjust a color reproduction characteristic of the image forming device based on the device-independent data.

摘要： An image reader includes a reading device to read an image on a recording medium, a first conveying roller pair upstream of the reading device in a conveyance direction of the recording medium, a second conveying roller pair downstream of the reading device in the conveyance direction, to hold the recording medium together with the first conveying roller pair to convey the recording medium, and a driver to drive the first conveying roller pair and the second conveying roller pair so that a relative relation between a reading position of the reading device and the recording medium held by the first conveying roller pair and the second conveying roller pair is constant. The reading device determines that the image read from the recording medium is effective in a period in which the relative relation is constant.

摘要： A photoelectric conversion device having plural photoelectric conversion pixels includes an imaging unit, a position identifying unit, an interpolation determining unit, and an interpolation processing unit. The imaging unit generates image data for each of plural colors based on light received in the photoelectric conversion pixels. The position identifying unit detects in the photoelectric conversion pixels a defective pixel outputting an electrical signal at an abnormal level, and stores position information of the defective pixel. The interpolation deter mining unit determines, based on respective pixel values of peripheral pixels peripheral to the defective pixel, whether to perform an interpolation process on the defective pixel. The interpolation processing unit performs the interpolation process on the defective pixel when the interpolation determining unit determines to perform the interpolation process on the defective pixel. The interpolation process approximates the electrical signal of the defective pixel to an electrical signal at a normal level.

摘要： A photoelectric conversion device includes a plurality of light receiving elements, a plurality of A/D conversion units, and an offset giving unit. The light receiving elements are arrayed in one direction and each convert a light signal into an electrical signal. The A/D conversion units perform A/D conversion on the electrical signals output from the light receiving elements. The offset giving unit gives an offset voltage of a certain level to the electrical signals output from the light receiving elements without flowing a steady current before the electrical signals are input into the A/D conversion units.

摘要： A reading device including a position reference member having a reference pattern having a line extending along a first direction of the position reference member, the position reference member movable in a second direction orthogonal to the first direction; a reader including a plurality of sensor chips arranged along the first direction, each of the sensor chips having a length defined by a plurality of pixels; and circuitry. The circuitry is configured to detect the reference pattern of the position reference member using the reader; determine coordinates of at least two sensor chips in the second direction, based on the detected reference pattern of the position reference member; and correct a position of a reading target in the second direction based on the coordinates determined for the at least two sensor chips of the reader in the second direction.
