Title:
撮像装置および画像の高解像度化方法
Document Type and Number:
Japanese Patent JP4429816
Kind Code:
B2
Abstract:
An optical system ( 101 ) forms an optical image on an imager ( 102 ), the image is made spatially discrete for transformation into a sampled image signal, and the image signal is separated at a band separation processing block ( 105 ) into a high-frequency component and a low-frequency component. At a super-resolution target frame selection block ( 106 ), a frame to which super-resolution processing is to be applied is selected out of the separated low-frequency component image for forwarding to an interpolation and enlargement processing block ( 109 ). super-resolution processing is implemented by a motion estimation block ( 107 ) and a high-resolution image estimation block ( 108 ) adapted to estimate image date having a pixel sequence at a high resolution. At a high-resolution image computation area determination block ( 112 ), an area in the image, to which high-resolution image estimation computation is to be applied, is determined, and the output of the high-resolution image estimation computation block ( 108 ) is forwarded to a combining computation processing block ( 110 ).
