Title:
DEVICE, METHOD AND PROGRAM
Document Type and Number:
Japanese Patent JP2015179968
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a device capable of acquiring HDR image data with as small number of imaging times and imaging types as possible while reducing the occurrence of a pseudo contour, when imaging a scene having a high dynamic range and acquiring image data.SOLUTION: A control device for controlling an imaging sensor (Fig. 2, 201) includes generation means (Fig. 3, 309) for selectively determining an exposure time from among at least two or more different exposure times, and for generating exposure time data indicative of a pixel-by-pixel exposure time for each pixel constituting the image data. The generation means calculates an output value from the acquired image data, determines a pixel-by-pixel exposure time on the basis of the calculated output value, calculates an error in the calculated output value, and diffuses the calculated error to each peripheral pixel of a processing target by an error diffusion method.
