Problems solved by technology

[0011] In addition, along with the fireworks, there is also a phenomenon that damages the clarity of the fireworks, such as smoke, etc.
Similarly, when photographing the movement trails of headlights of vehicles at night, when taking city roads as an object, exhaust gas floating on the road may spoil the clarity of the movement trails of the headlights.

Embodiment approach 1

[0033] Figure 1 to Figure 12 Embodiment 1 of the present invention is shown, figure 1 It is a block diagram showing the configuration of the imaging device. As will be described below, the imaging device of this embodiment functions as an image processing device that processes captured images.

[0034] Such as figure 1 As shown, the imaging device has: a lens 1, an imaging element 2, an image processing unit 3, an AF (autofocus) evaluation value calculation unit 4, a display unit 5, a shake detection unit 7, a shake correction unit 8, an exposure control unit 9, A focus control section 10 , a camera operation section 11 and a camera control section 12 . In addition, in figure 1 Although the memory card 6 is also described in , the memory card 6 is detachable from the imaging device, so it does not need to be a unique structure of the imaging device.

[0035] The lens 1 is an imaging optical system for forming an optical image of a subject onto an imaging area of ​​the im...

Embodiment approach 2

[0113] Figure 13 to Figure 15 Embodiment 2 of the present invention is shown, Figure 13 It is a flowchart showing the processing of the high-saturation relatively bright composition mode of the imaging device.

[0114] In this second embodiment, the same reference numerals and the like are assigned to the same parts as those in the first embodiment above, and explanations thereof are appropriately omitted, and only differences will be mainly described.

[0115] In the above-described embodiment, a relatively dark image is generated using a plurality of images to be combined in the high-saturation relatively bright combination processing. On the other hand, in this embodiment, a plurality of pieces of image data are acquired at a timing different from the timing of acquiring a plurality of pieces of image data to be combined in the high-saturation relatively bright combination processing, and based on at least a plurality of pieces of image data acquired at different timings...

Abstract

The invention provides an image processing device and an image processing method. An image processing device and the like capable of obtaining an image more vivid and impressive than an actual photographed scene. The image processing device includes: a saturation determination unit for determining whether or not the saturation of each pixel constituting the image data is in a high-saturation region for a plurality of pieces of image data obtained by photographing a subject in time series; a compositing unit that performs a relatively bright high-saturation compositing process on the plurality of image data. A pixel determined to be in the high-saturation region is replaced with a pixel value of a pixel having a higher index including a luminance component.

Description

technical field [0001] The present invention relates to an image processing device and an image processing method for synthesizing multiple pieces of image data captured in time series. Background technique [0002] In recent years, imaging devices such as digital cameras equipped with a relatively bright synthesis processing function have been proposed. Here, the comparatively brighter composition process is a process of comparing pixel values ​​at the same pixel position in a plurality of time-series images, and replacing the pixel value at the pixel position with the larger pixel value. [0003] This relatively bright composite processing is used to obtain multiple images obtained by shooting in time series (ie, continuous shooting) at a necessary and sufficiently short shutter speed in a shooting scene containing a relatively bright and small moving object, and can obtain moving objects. The locus of is a good image with a high S / N ratio. [0004] To name a few example...
