Problems solved by technology

[0014] However, the above-mentioned imaging device is basically assumed to be configured for monochrome image processing, so if it is applied to the color images, requires 3 times the amount of processing
In addition, near the edge of the processed image becomes irrelevant to each color of R, G, and B, so false colors occur, causing image quality degradation

Embodiment approach 1

[0063] figure 1 The configuration of the imaging processing device 1 according to the present embodiment is shown. The imaging processing device 1 includes a lens system 101 , a dichroic mirror 102 , a first imaging unit 103 , a second imaging unit 104 , an image processing unit 105 , and a control unit 120 .

[0064] Hereinafter, the function of each constituent element will be outlined first, and then the operation of each constituent element will be described in detail in relation to the operation of the imaging processing device 1 .

[0065] The lens system 101 converges light incident from the outside of the imaging processing device 1 , that is, an image of a subject.

[0066] The dichroic mirror 102 transmits a red (R) component and a blue (B) component of light, and reflects a green (G) component of light. That is, the dichroic mirror 102 separates incident light into a red (R) component, a blue (B) component, and a green (G) component. In addition, in the followin...

Embodiment approach 2

[0334] In Embodiment 1 described above, an example has been described in which imaging processing and high-resolution processing are performed using the same system. However, the two processes do not necessarily have to be performed in the same system.

[0335] In this embodiment, an example in which imaging processing and high-resolution processing are performed in different systems will be described.

[0336] Figure 13 An example of an image processing system composed of an imaging device 901 , a network 902 , and a processing device 903 according to the present embodiment is shown. Instead of the network 902, the medium 906 may be used to configure the image processing system according to this embodiment. Figure 14 Among them, for the imaging processing device of Embodiment 1 (such as figure 1 ) are assigned the same reference signs and their descriptions are omitted.

[0337] The imaging device 901 includes a lens system 101 , a dichroic mirror 102 , a first imaging...

Abstract

It is an object to provide an image processing device and an image processing method that are configured not to lower the amount of light incident on each camera and to generate a dynamic image with a high resolution at a high frame rate. An image picking-up processing device is comprised of a separation unit that separates visible light into at least first and second color components; a first image picking-up unit which picks up dynamic images of the first color component and carries out the exposure for a first electric charge accumulation period and the picking-up of each dynamic image with a first space resolution and with a first time resolution, a second image picking-up unit which picks up dynamic images of the second color component and carries out the exposure for a second electric charge accumulation period that is longer than the first electric charge accumulation period and the picking-up of each dynamic image with a second space resolution that is higher than the first space resolution and with a second time resolution that is lower than the first time resolution; a control unit that controls image picking-up conditions of the first and second image picking-up units; and a processing unit that generates a dynamic image of the second color component in which a time-space resolution is enhanced based on information of each dynamic image of the first and second color components.

Description

technical field [0001] The invention relates to image processing of dynamic images. Specifically, it relates to a technique for generating a moving image in which at least one of the resolution and the frame rate of the captured moving image is increased by image processing. Background technique [0002] In the field of image input in recent years, there has been progress in increasing the number of pixels and miniaturizing the pixel pitch of cameras for mobile phones and digital still cameras. [0003] According to the image quality required by the image camera, the spatial resolution is divided into multiple spans and used. For example, the resolution of a TV phone is about QCIF (Quarter Common Intermediate Format, 176 pixels horizontally, 144 pixels vertically), or a relatively low number of pixels such as QVGA (Quarter Video Graphics Array, 320 pixels horizontally, 144 pixels vertically). On the other hand, a digital one-eye reflex camera has a resolution exceeding 10 ...
