Imaging apparatus and image processing apparatus
[Object] To quickly and correctly reproduce an image intended by a photographer, a cinematographer, and the like on the occasion of post-production. [Solving Means] The development apparatus includes: an imaging unit that performs shooting and generates RAW data; a first conversion unit that converts the generated RAW data into image data by interpolation; an acquisition unit that acquires an exposure index value corresponding to an illuminance of a shooting environment; a first correction unit that corrects a value of the image data based on the exposure index value; and an output unit that associates the RAW data and the acquired exposure index value with each other and outputs the associated RAW data and exposure index value.
Image processing apparatus and image processing method for display mapping
An image processing apparatus and an image processing method which can transmit/receive or display a high-dynamic-range image suitably are provided. An image transmission apparatus transfers, as metadata of content, luminance conversion information, which is for conversion of HDR content (for example, with maximum luminance 2000 nit) into SDR content (having, for example, 100 nit), or differential information. Based on the metadata, an image reception apparatus generates luminance conversion information, in which received HDR content is adapted to a capability of a display (for example, with maximum luminance 500 nit or 1000 nit) in an output destination, and realizes display mapping which is not against an intention of a producer.
SENSOR-SYNCHRONIZED SPECTRALLY-STRUCTURED-LIGHT IMAGING
A spectral imaging device is configured to capture color images synchronized with controlled illumination from different color light emitting diodes. A processor in the device applies a coupling factor to sampled color images to convert sampled pixels into spectral channels corresponding to LED color and color filter. Multi-spectral spectricity vectors produced at pixel locations are used along with spatial information to classify objects, such as produce items.
IMAGE SIGNAL PROCESSOR AND METHOD FOR PROCESSING IMAGE SIGNAL
An image signal processor, and a method for processing an image signal, include a directionality strength determiner, a half-directional pattern determiner, and a pixel interpolator. The directionality strength determiner divides a target kernel including a target pixel into a plurality of sub-kernels, and generates gradient sum information by calculating directionality strength of each of the plurality of sub-kernels. The half-directional pattern determiner determines whether a half-directional edge pattern is included in each of the sub-kernels in response to the gradient sum information. The pixel interpolator interpolates the target pixel in response to the edge pattern determined by the half-directional pattern determiner.

Information processing apparatus, information processing terminal, method, and model
Provided is an information processing apparatus including an acquisition unit that acquires a second image obtained by photographing a color sample by a second camera device and by developing, and an estimation unit that estimates a second 3D-LUT for reproducing, by the first camera device, a color of the color sample in the second image by inputting the second image to a model that has learned a first image obtained by photographing the color sample under a standard light source by a first camera device and by developing as input data and a first 3D lookup table (3D-LUT) used for developing the first image as correct answer data. As a result, the 3D-LUT can be generated more easily.
IMAGE PROCESSOR FORMED IN AN ARRAY OF MEMORY CELLS
Apparatuses, systems, and methods related to an image processor formed in an array of memory cells are described. An image processor as described herein is configured to reduce complexity and power consumption and/or increase data access bandwidth by performing image processing in the array of memory cells relative to image processing by a host processor external to the memory array. For instance, one apparatus described herein includes sensor circuitry configured to provide an input vector, as a plurality of bits that corresponds to a plurality of color components for an image pixel, and an image processor formed in an array of memory cells. The image processor is coupled to the sensor circuitry to receive the plurality of bits of the input vector. The image processor is configured to perform a color correction operation in the array by performing matrix multiplication on the input vector and a parameter matrix to determine an output vector that is color corrected.
Color conversion information generation method, color conversion information generation system, and program therefor
A method for generating color conversion information including providing a user with color sample information for determining a color sample of which color characteristic information is known, receiving, from the user, an image including the color sample determined by the color sample information in a lighting environment, and generating color conversion information which corresponds to the lighting environment and is correlated with the user, based on the image and the color characteristic information of the color sample determined by the color sample information. The color conversion information converts between color information and color characteristic information, the color information is information which corresponds to a lighting environment and indicates colors of an object in the lighting environment, and the color characteristic information indicates color characteristics of the object.
MEDICAL SIGNAL PROCESSING DEVICE AND MEDICAL OBSERVATION SYSTEM
A medical signal processing device for processing an image obtained by an imaging unit including a plurality of pixels, and generating a video signal for display, includes a Y gamma-correction unit that performs Y gamma-correction on a luminance signal for each pixel in the image obtained by the imaging unit.

An apparatus includes an input circuit and a processing circuit. The input circuit may be configured to receive a sequence of pictures. The processing circuit may be configured to (i) generate a change factor based on gain information for a reference picture selected from the sequence of pictures, gain information for a target picture selected from the sequence of pictures, an average pixel value for the reference picture, and an average pixel value for the target picture, (ii) remap data of a selected one of the reference picture and the target picture by calculating pixel values for the selected picture using original pixel values of the selected picture and the change factor, and (iii) perform motion detection between the reference picture and the target picture utilizing (a) the remapped image data of the selected picture and (b) original data of the picture that was not remapped.
