| 20080259181 | IMAGING APPARATUS, IMAGING METHOD, INTEGRATED CIRCUIT, AND STORAGE MEDIUM - An imaging apparatus appropriately captures a large dynamic range image of even a scene including a backlit person with a blue sky background in a manner that the person's face has an appropriate luminance level without saturating the background sky. In the imaging apparatus, an imaging unit obtains analogue image signals through exposure control that prevents a highlight from being saturated, an A/D converter converts the analogue image signals to digital image signals, and a signal processing unit linearly increases the dynamic range of the digital image signals. The image signals with the increased dynamic range are nonlinearly compressed to have a dynamic range of 100% or less through nonlinear dynamic range compression that intensively compresses a highlight portion. The imaging apparatus with this structure first increases the dynamic range of an image and efficiently compresses the increased large dynamic range of the image. | 10-23-2008 |
| 20090033753 | IMAGING APPARATUS, IMAGING METHOD, STORAGE MEDIUM, AND INTEGRATED CIRCUIT - An imaging apparatus estimates a distance based on a reflectance value of a subject estimated with improved precision. An illumination unit illuminates a subject with illumination light. An imaging unit captures a plurality of images each under a different condition of the illumination unit.

| 20090231467 | IMAGING APPARATUS, IMAGING METHOD, STORAGE MEDIUM, AND INTEGRATED CIRCUIT - An imaging apparatus for capturing a moving image performs backlight correction of an image and outputs a natural image. The imaging apparatus electronically captures an image of a subject. An optical system has a light amount adjustment function. An imaging unit reads an optical image of the subject that is formed by the optical system. An A/D converter subjects an output of the imaging unit to A/D conversion. A backlight correction unit converts the tones of an image read by the A/D converter using a conversion characteristic selected differently according to a spatial position and at least increases the luminance level of a dark region of the image. An instruction unit instructs to start backlight correction. A control unit operates the backlight correction unit based on an instruction signal output from the instruction unit, and decreases an exposure light amount of the optical system by a predetermined amount. | 09-17-2009 |
