摘要： An image-taking apparatus is disclosed which allows preparatory driving for the next image-taking without degrading image quality and a reduction in time taken for one image-taking operation. The image-taking apparatus has a controller which controls an actuator which drives an operation mechanism which performs a first operation for allowing the image-taking with a photoelectrical conversion device and then a second operation (preparatory driving) for returning to the state before the first operation. The controller starts to drive the actuator for causing the operation mechanism to perform the second operation after the start of the travel of a rear curtain of a shutter and before the end thereof during accumulation of charge on the photoelectrical conversion device, or before reading of charge from the photoelectrical conversion device after the completion of exposure of the photoelectrical conversion device.

摘要： A microscope imaging system includes obtaining a second image area being a focus area composed of one or more pixels arbitrarily specified in a first image area indicated by an entire area or a predetermined area of an outputted image (24) ; generating a first brightness histogram of the first image area and a second brightness histogram of the second image area (151); calculating a relative brightness value of the second image area against the first image area by detecting a feature point of the second brightness histogram and calculating a position corresponding to a feature point of the second brightness histogram in the first brightness histogram (161); and controlling an imaging drive unit for driving an imaging unit until the brightness value reaches the calculated one (162).

摘要： A device has a processing unit to implement a set of operations to use both luma and chroma information from a scene of an image to dynamically adjust exposure time and sensor gain. The processing unit collects bright near grey pixels and high chroma pixels in the scene. Based on the collected pixels, brightness of the near grey pixels is increased to a predetermined level without saturation. At the same time, the high chroma pixels are kept away from saturation.

摘要： Disclosed are a method of and an apparatus for controlling exposure in halftone photography by calculating a main exposure amount (T M ), a bump exposure amount (T H ) and a flash exposure amount (T F ) based on basic data peculiar to the combination of a screen (36) and a photosensitive material (37) original data depending on an original (35) in a process camera. The method includes the steps of preparing the basic data and the original data, obtaining a dot image by exposing the original (35) to a photosensitive material (37) through a screen (36) based on the prepared basic data and original data, defining a resultant dot percentage correction value by obtaining differences between dot percentages of the portions of the obtained dot image which portions corresponding to a highlight region and a shadow region of the original, respectively, and the respective desired values, and correcting at least one of the main exposure amount (T M ), the bump exposure amount (T H ) and the flash exposure amount (T F ) based on the resultant dot percentage correction value and the basic data. The difference between the dot percentage of the dot image obtained as a result of the exposure and a desired value can be used as a correction value, and therefore, a dot image having a desired dot percentage can be obtained without requiring a difficult procedure of evaluating a correction result.
