Imaging apparatus, solid-state imaging element, camera module, drive control unit, and imaging method

Abstract

The present invention pertains to an imaging apparatus, a solid-state imaging element, a camera module, a drive control unit, and an imaging method by which the effects of movement upon images can be reliably corrected. The drive control unit, on the basis of physically detected movement of an imaging unit for imaging a subject via an optical system for collecting light from the subject, relatively moves in at least one of the optical system and the imaging unit, calculates the amount of movement in the process of optically correcting blurs appearing in an image captured by the imaging unit, and controls the driving of at least one of the optical system and the imaging unit. A signal processor, on the basis of optical axis-directional positional information, movement information, and optical axis-directional positional information, performs signal processing to correct the effects of the movement of the imaging unit on images according to a function that converts position according to positional information, movement information, and optical axis-directional positional information synchronized at each of coordinates on an image. The present invention can be applied, for example, to a stacked CMOS image sensor.

Description

technical field [0001] The present disclosure relates to an imaging device, a solid-state imaging element, a camera module, a driving control unit, and an imaging method, and in particular, to an imaging device, a solid-state imaging element, a camera module, a driving control unit, and an imaging device capable of reliably correcting the influence of motion on an image. camera method. Background technique [0002] Conventionally, an optical camera shake correction (OIS: Optical Image Stabilizer) or an electronic camera shake correction (EIS: Electronic Image Stabilization) is used as a technique for correcting camera shake in an imaging apparatus. In optical camera shake correction, blur can be corrected by moving a lens or an imaging element relatively in parallel and moving the position of an image on the imaging element according to the amount of blur. In electronic camera shake correction, an image captured by an image pickup element is cropped as an output image, and ...

AI Technical Summary

Problems solved by technology

Since this rotational movement is corrected by the parallel movement of the lens or imaging element, optical camera shake correction techniques suffer from peripheral distortion

Similarly, electronic camera shake correction also suffers from peripheral distortion since the correction moves the clipping position in parallel

[0004] Also, for distortion caused by a difference in the amount of motion within one screen due to a difference in the exposure timing for each pixel row that occurs in an imaging element using a rolling shutter such as a complementary metal oxide semiconductor (CMOS) image sensor (focal plane phenomenon), no measures taken
