Image signal processing device and method

Abstract

When a method or apparatus of assuring simultaneous exposure, such as a mechanical shutter, is not provided with a MOS imaging sensor, moving subjects are distorted with a MOS image sensor when capturing a still image of a fast-moving subject because imaging and reading are not simultaneous across the MOS sensor. Changing the MOS sensor exposure sequence and reading sequence, and interpolating the read data, change and correct the read sequence line by line when imaging a high resolution moving image, and thus improve distortion in moving subjects.

1 . An image signal processing device comprising:
 an image sensor;   a horizontal pixel control unit operable to control a horizontal pixel access in said image sensor;   a signal processing unit operable to change and specify an access sequence to said horizontal pixel control unit;   a horizontal pixel data reading unit operable to read horizontal pixel data from said image sensor;   a horizontal moving subject pixel detection unit operable to detect horizontal pixels containing moving subject data from the data read from said horizontal pixel data reading unit; and   a horizontal pixel correction unit operable to correct the read horizontal moving subject pixels.
