An imaging processing system includes an image pickup device that has circuitry which creates, from raw image data, image data including a first gamut, and compression-codes the image data including the first gamut to generate compression-coded image data. The system also includes an image processing device that has circuitry which decodes the compression-coded image data to generate uncompressed image data, which includes the first gamut. The circuitry of the image processing device also converts the uncompressed image data including the first gamut into image data including a second gamut, where the first gamut encompasses the second gamut.

Image processing system and image processing method

There is provided a signal processor including correction circuitry configured to correct a signal for each color input to the signal processor and to output the corrected signal for each color, first conversion circuitry configured to receive the corrected signal for each color, to perform first image processing on each corrected signal for each color, and to generate a first signal having a first color gamut for each color, second conversion circuitry configured to receive the corrected signal for each color, to perform second image processing on each corrected signal for each color, and to generate a second signal having a second color gamut for each color, where the signal processor outputs a first image data having a first color gamut and a second image data having a second color gamut from same corrected signals for each color.

Imaging apparatus, imaging system, and imaging method

A gamut converting device that applies gamut conversion to image data includes a signal converting unit that performs, when a negative value is included in an image signal value forming the image data, processing for converting the image signal value forming the image data to eliminate the negative value from the image signal value and a gamut converting unit that applies the gamut conversion to the image data, the image signal value of which is converted by the signal converting unit.

Gamut converting device and gamut converting method

Disclosed herein is a video conversion device including a color characteristic memory, a color characteristic correction processor, a selector, and a controller.

Video conversion device, video conversion method, and program

An image processing device that performs color conversion processing using a lookup table (LUT) includes an acquiring unit that acquires an emulation LUT for applying emulation of a gamut to a target device from a device in use, the emulation LUT being generated using a device-in-use LUT for performing correction corresponding to input and output characteristics of the device in use and a target device LUT for performing correction corresponding to input and output characteristics of the target device, and a converting unit that performs gamut conversion in performing the emulation using the emulation LUT acquired by the LUT acquiring unit.

Image processing device and image processing method performing color conversion processing using a lookup table

A gamut compressing device for compressing video data in a first gamut into video data in a second gamut. The device includes a compression unit compressing a value of color data in the first gamut, not contained in the second gamut, into a value of color data contained in the second gamut through a predetermined compression calculation. A gradation generating unit generates gradation such that a plurality of values of color data having the same value as a result of the compression become different in the second gamut.

Gamut compression method, program, and gamut compression device

An apparatus and a method for flexibly adjusting the contrast of an input image signal. Specifically, a control signal for controlling the contrast of a displayed image is generated responsive to an input image signal, and the luminance signal level of the input image signal is adjusted on the basis of the generated control signal. A display image for demonstration via a liquid crystal display surface is generated on the basis of the adjusted luminance signal level. The illumination brightness on the liquid crystal display surface is controlled in correlation with the adjustment of the luminance signal level on the basis of the generated control signal.

Image display controlling apparatus and method, imaging apparatus and viewfinder device

An image processing apparatus and an image processing method permit easy adjustment of luminance and contrast, and also permit easy check of the brightness of a target image. A signal format of an image signal is determined by a determiner circuit, and an image signal of a luminance reference image that provides the standard for determining luminance is generated by a luminance reference signal generator circuit on the basis of a result of the determination. A mixing circuit generates an image signal for displaying a target image combined with a luminance reference image. The signal level of the image signal is adjusted by an adjusting circuit so as to adjust luminance and/or contrast. A discrimination display signal superimposing circuit generates a signal of a luminance identifying image superimposed in a desired luminance area. From the luminance reference image, the brightness at a desired position on an image can be easily checked.

Image processing apparatus and image processing method

A solid-state imaging apparatus capable of changing a vertical resolution (MTF) without damaging the dynamic resolution. A CCD drive circuit 6 for driving a CCD image sensor 2 of an imaging section 3 is controlled by a control section 7 to independently vary effective charge storage periods of respective photoelectric conversion of the CCD image sensor 2 with respect to photoelectric conversion of odd columns and photoelectric conversion elements of even columns and to add and mix, every field, image pick-up charges obtained by respective adjacent photoelectric conversion elements of odd and even columns to read them out. A CCD drive circuit 6 for driving a CCD image sensor 2 of an imaging section 3 may also be controlled by a control section 7 to carry out control of the electronic shutter function of the CCD image sensor 2, and to control the effective charge storage periods of respective photoelectric conversion elements in a manner caused to interlock with the electronic shutter function.
