Embodiment Construction

[0027] Now, preferred embodiments of the present invention will be described in detail, and examples thereof are illustrated in the accompanying drawings. Wherever possible, the same reference numerals will be used throughout the drawings to refer to the same or similar parts.

[0028] FIG. 1 illustrates the broad outline of an image processing apparatus according to the prior art, and, figure 2 The lighting control part in FIG. 1 is explained in more detail.

[0029] 1, the image processing apparatus includes: an image pickup section 1 that obtains an image under low-light conditions; an image correction section 2 that corrects the brightness and brightness of an image obtained by the image pickup section 1 under low-light conditions Color; and an image output section 6, the image output section 6 outputs the image corrected by the image correction section 2.

[0030] The image pickup section 1 is an element for capturing a normal image, and an image sensor, for example, CCD (Ch...

Abstract

An image processing apparatus is provided. In the image processing apparatus, an image pick-up part obtains an image, an image compensation part stretches gray values of. selected pixels from a main object of the obtained image (the selected pixels lie in a narrower gray value range) to a wider gray value range, and an image output part outputs the compensated image. Therefore, an image is compensated for a user to easily discern an object in the image in a preview mode.

Description

Technical field [0001] The present invention relates to an image processing device, in particular to an image processing device capable of obtaining and capturing high-definition images under low lighting conditions. The present invention more particularly relates to a device capable of obtaining high-brightness and high-definition images in a preview mode before capturing the image. Background technique [0002] With the increase in applications of digital imaging devices, such as digital camcorders and camera phones, the functions of these devices have become diversified and more intelligent. [0003] Therefore, when the digital imaging device obtains still or moving images, the resolution gradually increases, and under bright conditions, that is, under daylight or artificial lighting, the obtained images are sufficient to meet user requirements. [0004] However, users have a demand for capturing high-definition images not only under normal lighting but also under low-light co...
