The invention provides a portrait enhancement type camera, which comprises a camera body and a lens, wherein external light rays are incident into the camera body through the lens; a filter lens positioned right behind the lens is arranged in the machine body, and the filter lens and the incident direction of external light are obliquely arranged at an angle of 45 degrees; the filter is a flat lens made of transparent materials, and an infrared reflection film is covered on the surface facing to external light so as to reflect infrared components in incident light to a first CCD in the machine body; and the incident light transmitted through the filter is transmitted to the second CCD; the image processing module is arranged in the machine body, defines an area where no infrared image is formed in the image formed by the first CCD as a mark area, and performs pasting processing on the area corresponding to the mark area in the image formed by the second CCD. The camera can obtain prominent portrait effect under the condition that objects around the human body are more.

Description

Human image enhanced camera

Technical Field

The present invention relates to the field of image pickup apparatuses, and particularly, to a video camera.

Background

The portrait photography, that is, the photography form with people as the main object, is an important classification in the photography art, and during the photography process, the image of the people to be photographed needs to be highlighted, so that the scenery around the portrait forms a fuzzy effect; however, in the actual portrait shooting, when there are many objects near the human body, after focusing through the lens, since the objects are located in the substantially same distance range with the human body, the surrounding objects cannot be pasted, and at this time, it is difficult to obtain the prominent portrait effect.

Disclosure of Invention

In view of the above problems, it is an object of the present invention to provide a portrait-enhanced camera that can obtain a prominent portrait effect even when there are many objects around a human body.

The technical scheme adopted by the invention for solving the technical problems is as follows: the portrait enhancement type camera comprises a camera body and a lens, wherein external light is incident into the camera body through the lens; a filter lens positioned right behind the lens is arranged in the machine body, and the filter lens and the incident direction of external light are obliquely arranged at an angle of 45 degrees; the filter is a flat lens made of transparent materials, and an infrared reflection film is covered on the surface facing to external light so as to reflect infrared components in incident light to a first CCD in the machine body; and the incident light transmitted through the filter is transmitted to the second CCD; the image processing module is arranged in the machine body, defines an area where no infrared image is formed in the image formed by the first CCD as a mark area, and performs pasting processing on the area corresponding to the mark area in the image formed by the second CCD.

Preferably, the reflection wavelength of the infrared reflection film on the surface of the filter is 8 um-12 um, so that the infrared reflection film can only reflect the spontaneous infrared light of human skin.

Preferably, the front surface of the first CCD is covered with an infrared filter which only allows infrared light with the wavelength of 8 um-12 um to pass through so as to completely shield the interference of the rest reflected light.

Preferably, the image processing module performs the blurring process as follows: for any pixel point to be processed, a 3 × 3 matrix pixel point array is drawn with the pixel point as the center, so that the pixel value of the pixel point to be processed is replaced by the pixel value of a random pixel point in the pixel point array. According to the processing mode, each pixel point needing to be gelatinized does not need to be subjected to function operation, and only the pixel value of each pixel point is assigned to the array and the array is rearranged, so that the operation of the image processing module can be simplified, and a high-cost operation chip is not needed.

The invention has the beneficial effects that: when the portrait enhancement type camera shoots a portrait, external light enters the camera body through the lens, infrared components in the portrait enhancement type camera are reflected to the first CCD by the filter to form an infrared picture, and the light penetrating through the filter irradiates to the second CCD to form a normal picture; then an image processing module defines an area where an infrared image is not formed in the infrared image imaged by the first CCD as a mark area, and performs pasting processing on the area corresponding to the mark area in the normal image imaged by the second CCD; because only the human body has strong infrared effect in the shot picture, the areas except the human body are in a fuzzy state in the finally formed picture, and only the human body area has clear imaging, so that the camera can obtain prominent portrait effect under the condition that objects around the human body are more.

Detailed Description

The invention is further illustrated with reference to the following figures and examples:

in the embodiment shown in fig. 1, the image-enhanced camera includes a body 1 and a lens 2, and external light is incident into the body 1 through the lens 2; a filter 3 positioned right behind the lens 2 is arranged in the machine body 1, and the filter 3 is obliquely arranged at an angle of 45 degrees with the incident direction of external light; the filter 3 is a flat lens made of a transparent material, and is covered with an infrared reflection film 30 on a surface facing external light to reflect an infrared component of incident light to a first CCD4 in the body 1; the incident light transmitted through the filter 3 is transmitted to the second CCD 5; an image processing module is further arranged inside the body 1, the image processing module defines an area where no infrared image is formed in the image imaged by the first CCD4 as a mark area, and performs a pasting process on an area corresponding to the mark area in the image imaged by the second CCD 5.

In addition, the reflection wavelength of the infrared reflection film 30 on the surface of the filter 3 is 8 um-12 um, so that the infrared reflection film can only reflect the spontaneous infrared light of human skin.

In addition, the front surface of the first CCD4 is covered with an infrared filter 40 which only allows infrared light with the wavelength of 8 um-12 um to pass through so as to completely shield the interference of the rest reflected light.

In addition, the image processing module performs the blurring processing as follows: for any pixel point to be processed, a 3 × 3 matrix pixel point array is drawn with the pixel point as the center, so that the pixel value of the pixel point to be processed is replaced by the pixel value of a random pixel point in the pixel point array. According to the processing mode, each pixel point needing to be gelatinized does not need to be subjected to function operation, and only the pixel value of each pixel point is assigned to the array and the array is rearranged, so that the operation of the image processing module can be simplified, and a high-cost operation chip is not needed.

When the portrait enhancement type camera shoots a portrait, external light enters the camera body 1 through the lens 2, infrared components in the light are reflected to the first CCD4 by the filter 3 to form an infrared picture, and the light penetrating through the filter 3 irradiates to the second CCD5 to form a normal picture; then, an image processing module defines an area where an infrared image is not formed in the infrared image imaged by the first CCD4 as a mark area, and performs gelatinization processing on the area corresponding to the mark area in the normal image imaged by the second CCD 5; because only the human body has strong infrared effect in the shot picture, the areas except the human body are in a fuzzy state in the finally formed picture, and only the human body area has clear imaging, so that the camera can obtain prominent portrait effect under the condition that objects around the human body are more.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
