Image processing device and imaging control device

Abstract

An ultra-resolution process unit (25) includes: a differential image generation unit (33) which generates differential image data; an image update unit (37) which calculates a evaluation value according to the differential image data and updates the high-resolution image data so that the evaluation value is reduced if the evaluation value exceeds a predetermined threshold value; a region extraction unit (35) which extracts a first region containing an inappropriate exposure pixel from the captured image data; and a weighting differential image generation unit (36) which weights the pixel corresponding to the first region of the differential image data. The image update unit (37) updates the high-resolution image data by using a plurality of differential image data items which have been subjected to the weighting. Accordingly, even if the captured image data includes an inappropriate exposure pixel, it is possible to generate highly accurate high-resolution image data in which a shape and a color of the imaged object are accurately reflected. This can reduce the affect of the inappropriate exposure pixel contained in the captured image data on the high-resolution image data.

Description

technical field [0001] The present invention relates to an image processing device and the like for generating one high-resolution image data from a plurality of low-resolution image data. Background technique [0002] The resolution of an image captured by an imaging device such as an area sensor is limited by the density of imaging elements included in the imaging device. Users of imaging devices require imaging devices capable of capturing images with higher resolution. In order to meet the needs of users for resolution, various camera manufacturers continue to release high-resolution cameras with a high density of imaging elements. [0003] However, there is a problem that there is a limit to the increase in the density of imaging elements, and the increase in density increases the manufacturing cost of the imaging device. In this regard, the following high-resolution technology has been used in the past, that is, the same subject is photographed multiple times, and the...

The whitened or blackened part cannot be used to represent the color or shape of the subject

[0050] Therefore, when a plurality of low-resolution image data (captured image data) used for super-resolution processing or image shift processing contains whitened or blackened components, the captured images cannot be correctly reflected in the high-resolution image data. The shape or color of the object, resulting in a problem that the accuracy of high-resolution processing decreases
