An object of one embodiment of the present invention is to accurately derive an inclination of a line image sensor. One embodiment of the present invention is an image reading apparatus including: a line image sensor in which reading elements for reading an image are arrayed in a predetermined direction; a first derivation unit configured to, based on read data acquired by reading a chart on which a plurality of dot patterns is printed with the line image sensor, derive coordinates of each of the plurality of dot patterns; a second derivation unit configured to derive an inclination angle of the line image sensor based on the coordinates derived by the first derivation unit; and a first calculation unit configured to calculate a first correction value for correcting the inclination of the line image sensor based on the inclination angle derived by the second derivation unit.

Image reading apparatus, control method thereof, and storage medium

A sensor includes a photoelectric conversion unit including a first photoelectric conversion element array and a second photoelectric conversion element array, each having an array of a plurality of photoelectric conversion elements arranged in a predetermined direction, a storage unit configured to store a charge generated by the photoelectric conversion unit, a transfer unit configured to transfer the charge generated by the photoelectric conversion unit to an outside of the sensor, a control unit configured to serially execute a first transfer control for transporting unit configured to transport a charge stored in the second photoelectric conversion element array to the transfer unit via the storage unit and a second transfer control for transporting unit configured to transport a charge stored in the first photoelectric conversion element array to the transfer unit via the second photoelectric conversion element array and the storage unit.

Sensor and sensor control method

A recording apparatus includes a generating unit for generating a window signal for setting the driving timing of the recording head for each nozzle array, a recording buffer in which the addresses are consecutively arranged corresponding to the conveying direction of the recording medium to store and read recording data, a first SRAM for storing data read from the recording buffer, a second SRAM for storing data read from the first SRAM according to tilt information associated with each respective block of nozzles, and a transfer unit configured to transfer data read from the second SRAM to a nozzle array.
