摘要： An image pickup apparatus that is capable of reducing degradation of image quality of the whole display screen of a display section while improving display delay with respect to an observed area. In an image pickup apparatus, an image pickup section picks up an image of an object, and a development processor generates image data by developing input data acquired by the image pickup section. A first image generation unit generates a first image by performing image processing on part of the image data. A second image generation unit performs predetermined image processing on the image data to thereby generate a second image which is different in the number of steps of image processing from the above image processing. An image synthesis section generates a third image by synthesizing the first image with the second image, and a display device displays the third image.

摘要： An image capturing apparatus which captures an image of a subject with an image sensor having pixels each including a plurality of areas and generates a RAW image for each of the plurality of areas from a signal generated by the image sensor. The apparatus generates a first RAW image and a second RAW image from the RAW images, generates first image data by performing first development on the first RAW image, generates first RAW image data and second RAW image data by compressing the first RAW image and the second RAW image and performs second development on the first RAW image having a higher processing load than the first development. Second image data is generated by the second development on the first RAW image by using the second RAW image.

摘要： An image processing apparatus for performing processing that rounds down C bits from an A-bit image, and that causes a B=(A−C) bit image resulting from the rounding down processing to be displayed comprises a time dithering unit configured to express a pixel value that is an intermediate value of one step in the (A−C) bits in the A-bit image by selectively outputting in each frame across N frames a value where the intermediate value was rounded down and a value where the intermediate value was rounded up, and to artificially express the A-bit image with a dither pattern where the N frames is a minimum unit, wherein the time dithering unit sets the value of N so that M/N is 25 or more.

摘要： An image processing apparatus capable of making a user confirm effect of HDR reliably. An acquirer acquires a luminance component of an input image. A converter converts the luminance component acquired by the acquirer into a predetermined luminance value for each pixel. A generator generates a graph waveform image that shows a graph showing a distribution of the luminance values obtained through the conversion by the converter. A display controller displays the graph waveform image generated by the generator on a display unit. When the input image is recorded in a first mode, an axis representing the luminance values in the graph is a logarithmic axis, and the generator generates a logarithmic graph waveform image showing the distribution of the luminance values based on the logarithmic axis.
