Embodiment Construction

[0030] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0031] First, refer to figure 1 A multi-point metering method according to an embodiment of the present invention is described. The multi-point light metering method according to the embodiment of the present invention is applicable to, for example, a display processing apparatus such as a camera or a portable terminal having a camera module. The display processing device includes a viewfinder display screen for the user to view the viewfinder state in real time. In addition, the display processing device further includes a touch sensing unit. The touch sensing unit may be stacked with the viewfinder display screen. For example, the touch sensing unit may be disposed above the viewfinder display screen to form a touch display screen.

[0032] Specifically, when the multi-point metering in this embodiment of the present invention starts, the di...

Abstract

The invention provides a multi-point light metering method, a multi-point light metering device and a display processing device. The multi-point light metering method includes: detecting of first gesture input and second gesture input to obtain at least one first touch point correspond to the first gesture input and at least one second touch point corresponding to the second gesture input; determining a first light metering area corresponding to the first gesture input on the basis of the first touch points; determining a second light metering area corresponding to the second gesture input on the basis of the second touch points; and performing light metering to the first light metering area and the second light metering area respectively to obtain a first metering value regarding to the first light metering area and a second metering value regarding to the second light metering area, wherein the first light metering area is different from the second light metering area.

Description

technical field [0001] The present invention relates to the field of display processing, and more particularly, the present invention relates to a multi-point light metering method, a multi-point light metering device and a display processing device. Background technique [0002] When shooting with a display processing device such as a camera or a portable device with a camera module, it is often encountered that a photographer wishes to meter the background and the subject at the same time to obtain exposure values ​​of both. [0003] Among the display processing devices in the prior art, there is a display processing device with a touch viewfinder frame, and a photographer can specify an object by clicking a certain point in the touch viewfinder frame, so that the measurement in the display processing device light meter for light metering. However, this metering device only supports single-point metering and cannot handle situations where you want to meter two or more poi...
