Abstract

A signal processing device performs a displaying process in a display unit on the basis of a parameter being predetermined in an image capture device provided with an anamorphic lens.

First claim

The invention claimed is:

1. A signal processing device, comprising:
circuitry configured to:
perform a displaying process in a display unit based on parameters being predetermined in an image capture device provided with an anamorphic lens, wherein
the parameters are an F value in a direction corresponding to a vertical direction of the anamorphic lens and an F value in a direction corresponding to a horizontal direction of the anamorphic lens.

2. The signal processing device according to claim 1 , wherein
the circuitry is further configured to display an icon indicating an in-focus state on the display unit as the displaying process.

3. The signal processing device according to claim 2 , wherein
the circuitry is further configured to determine a mode of displaying the icon based on a result of comparison between an amount of focus deviation and an average of the F value in the direction corresponding to the vertical direction and the F value in the direction corresponding to the horizontal direction.

4. The signal processing device according to claim 1 , wherein
the circuitry is further configured to determine whether to display an icon indicating a plurality of in-focus areas on the display unit based on the F value in the direction corresponding to the vertical direction of the anamorphic lens and the F value in the direction corresponding to the horizontal direction of the anamorphic lens.

5. The signal processing device according to claim 1 , wherein
the circuitry is further configured to control display of an icon indicating a subject detected by a subject detection function in the display unit as the displaying process.

6. A signal processing device comprising:
circuitry configured to:
perform a displaying process in a display unit based on parameters being predetermined in an image capture device provided with an anamorphic lens, wherein
the parameters are a magnification of zoom in a direction corresponding to a vertical direction of the anamorphic lens and a magnification of zoom in a direction corresponding to a horizontal direction of the anamorphic lens,
the displaying process controls a state of a plurality of in-focus areas in the display unit, and
the state of the plurality of in-focus areas is changed based on the parameters.

7. The signal processing device according to claim 6 , wherein
the circuitry is further configured to change the state of the plurality of in-focus areas corresponding to a compressed state in the horizontal direction of an image, being based on an image capture signal acquired by using the anamorphic lens, so as to be different from the state of the plurality of in-focus areas corresponding to a stretched state in the horizontal direction of the image.

8. The signal processing device according to claim 7 , wherein
the state of the plurality of in-focus areas is an arrangement of the plurality of in-focus areas, and
the circuitry is further configured to change arrangement of the plurality of in-focus areas so that the arrangement of the plurality of in-focus areas corresponding to the compressed state is denser than the arrangement of the plurality of in-focus areas corresponding to the stretched state.

9. A signal processing method, comprising:
performing a displaying process in a display unit included in an image capture device based on parameters being predetermined in the image capture device provided with an anamorphic lens, wherein
the parameters are an F value in a direction corresponding to a vertical direction of the anamorphic lens and an F value in a direction corresponding to a horizontal direction of the anamorphic lens.

10. A non-transitory computer-readable medium having stored thereon computer-executable instructions, which when executed by a computer, cause the computer to execute operations, the operations comprising:
performing a displaying process in a display unit included in an image capture device based on parameters being predetermined in the image capture device provided with an anamorphic lens, wherein
the parameters are an F value in a direction corresponding to a vertical direction of the anamorphic lens and an F value in a direction corresponding to a horizontal direction of the anamorphic lens.

11. An image capture device, comprising:
an anamorphic lens; and
a signal processing unit configured to perform a displaying process in a display unit based on parameters being predetermined, wherein
the parameters are an F value in a direction corresponding to a vertical direction of the anamorphic lens and an F value in a direction corresponding to a horizontal direction of the anamorphic lens.
