This disclosure provides systems, methods, and devices for image signal processing that support adjusting a Bokeh effect in image data. In a first aspect, a method of image processing includes receiving a first user input specifying a first depth of focus. A camera is configured with a first aperture size of a plurality of aperture sizes of the camera that is nearest a second aperture size that corresponds to the first depth of focus. The first aperture size is smaller than the second aperture size. Image data representing a scene is received that is captured with the first aperture size of the camera. First modified image data is determined by applying a first blur kernel to the image data. The first modified image data represents the scene at the depth of focus corresponding to the second aperture size. Other aspects and features are also claimed and described.

The present invention relates to the field of video camera image processing. Disclosed are an intelligent adjustment method when a video camera performs automatic exposure and an apparatus therefor. In the present invention, a first corresponding relationship between a rate and an aperture is pre-set. The first corresponding relationship records corresponding upper and lower aperture limits required by each rate for achieving the best depth of field of an image. The method comprises the following steps: acquiring the current rate of a video camera; searching for upper and lower aperture limits corresponding to the current rate in a first corresponding relationship; if the current aperture value exceeds the range of the searched upper and lower aperture limits corresponding to the current rate, adjusting the current aperture value to be within the range of the upper and lower aperture limits; and according to the adjusted aperture value, adjusting exposure time and gain to satisfy the need of image brightness. In the present invention, according to different field scenario rates, the aperture is adjusted to be within the aperture range corresponding to the best depth of field so as to acquire the best depth of field, and a shutter and gain are adjusted accordingly, so that the best brightness can be ensured and the best depth of field is achieved at the same time so as to improve image quality.

An image pickup apparatus being capable of performing a photometry process under a suitable condition and of achieving high-speed continuous photographing. A first drive, which accumulates and reads an electric charge with an image sensor for a photometry process, and a second drive, which accumulates and reads an electric charge to obtain an image signal for a static image, are alternately repeated during continuous photographing. A photometry process is performed based on the electric charge read by the first drive. An aperture value for obtaining the image signal of an (N+1)th frame is calculated based on a result of the photometry process during accumulation for obtaining the image signal of an N-th frame. A control unit controls a diaphragm based on the calculated aperture value and a predetermined aperture value during reading of the electric charge for obtaining the image signal of the N-th frame.
