Embodiment Construction

[0047] see figure 1 , the image generating device 10 of the present invention is applied in an electronic device 50 . In this embodiment, the electronic device 50 may be a device with a data processing function such as a smart phone. The electronic device 50 includes a processor 30 , a memory 20 and a camera set 60 , wherein the processor 30 can exchange data with the memory 20 through a bus 40 . Several program codes are stored in the memory 20 to be executed by the processor 30 to realize the functions of the image generating device 10 . In this embodiment, the electronic device 50 is configured to take a picture through the camera set 60 to generate a color image. The color image can be a first type of color image (such as RGB color image) or a second type of color image (such as CMKY color image), wherein the RGB color image includes red, green, blue A monochrome image of three channels, the CMKY color image includes a monochrome image of four channels of cyan, magenta,...

Abstract

An image generation device comprises an acquisition unit, a matching unit and a synthesis unit, wherein the acquisition unit is used for acquiring a monochromatic channel image contained in one corresponding colored image through multiple camera devices; the matching unit is used for performing matching operation on each monochromatic channel image to acquire an overlapped area in each monochromatic channel image; the synthesis unit is used for acquiring a monochromatic value of each pixel point in the overlapped area according to each monochromatic channel image; the colored images are synthesized according to each monochromatic value of each pixel point in the overlapped area. The invention further provides an image generation method. According to the image generation device and method, each monochromatic channel image in each colored image is acquired via different camera devices, accordingly, the real color of a shot object can be better reduced, generation of a pseudo color is avoided, and the defect of image resolution reduction caused by the fact that generation of Moire patterns is reduced through a low-energy filter is overcome.

Description

technical field [0001] The invention belongs to the technical field of digital photography, and in particular relates to an image generation method and device. Background technique [0002] The principle structure of digital photography is mainly composed of multiple core components, such as CCD (Charge-coupled Device, charge-coupled device) or CMOS (Complementary Metal Oxide Semiconductor, complementary metal oxide semiconductor) image sensor, A / D (Analog to Digital, Analog-to-digital) converter, digital signal processor MPU (MicroProcessor Unit, micro processing unit) or DSP (Digital Signal Processor, digital signal processor), image memory, LCD (Liquid Crystal Display) liquid crystal display and output interface, etc. The working mode of digital photography is: when shooting a scene, the optical image is imaged on the CCD or CMOS image sensor through the lens. The optical image is converted into an analog electrical signal by a CCD or CMOS image sensor, and then converte...
