Some aspects of the disclosure provide a method for camera operation control in an electronic device. The method includes obtaining, based on a plurality of frames associated with a target time slice, a first target parameter to be met by a camera of a virtual camera system in the target time slice. Then, the method includes determining a target operation speed of the camera in the target time slice at least partially based on the first target parameter and a time-speed change magnification curve, and controlling the camera to operate based on the target operation speed. Apparatus and non-transitory computer-readable storage medium counterpart embodiments are also contemplated.

A non-limiting example game system includes a main body apparatus, and the main body apparatus executes a virtual game, and a game screen is displayed on a display. A player character, a first fellow character and background objects such as the ground, trees and rocks are displayed in the game screen. A judgment object of a rectangular parallelepiped is set to the player character, and it is judged whether line segments each connecting each of multiple judgment points that are set to vertices of the rectangular parallelepiped to a position of a virtual camera collide with the background object, respectively. When the number of the line segments that collide with the background object is two or more, it is judged that a silhouette of the player character is to be displayed. If it is judged that the silhouette of the player character is to be displayed, a silhouette of a part or whole of the player character that is hidden behind the background object when viewed from the virtual camera is displayed on a surface of the background object.

This application discloses a method for updating a virtual environment picture performed by a computer device. The method includes: displaying a first virtual environment picture of a virtual environment using a first observation position as an observation center, wherein a virtual character is located at a first position in the first virtual environment picture; in response to receiving a first directional operation on the virtual character, displaying a skill indicator in accordance with the first directional operation; and when at least a portion of the skill indicator is going to exceed the first virtual environment picture, replacing the first virtual environment picture with displaying a second virtual environment picture, wherein the virtual character is relocated from the first position in the first virtual environment picture to a second position in the second virtual environment picture so as to present the skill indicator in the second virtual environment picture.

Systems and methods for verifying an advertisement impression in a digital environment are provided. In some aspects, methods of the subject technology include operations for defining a portion of the digital environment as an impression area, wherein the impression area is associated with a tagged advertisement area, providing a stream of an advertisement to the tagged advertisement area, and updating advertising impression information stored in memory regarding the advertisement, wherein an advertising impression is based on the identification of the character within the impression area and the availability of an unobstructed line-of-sight between the character and the tagged advertisement area. In some aspects, computer readable media are also provided.

Provided is an information processing apparatus that controls a virtual camera to shoot an attention object without restriction on the degree of freedom of operation of a player object. A game apparatus generates an image virtually captured by the virtual camera in a virtual space. A game operation unit controls at least a position of the player object in the virtual space on the basis of an input by a player. A virtual camera setting unit controls the virtual camera in such a manner that at least any one of the player object and an attention enemy object is included in an imaging range on the basis of a position of the player object and a position of the attention enemy object. A game operation unit controls the player object on the basis of the input by the player regardless of control of the virtual camera.

Techniques and systems for tracking multiple objects over a common time period and identifying (i.e., disambiguating) the objects from one another. As described herein, each object may include a respective light source (e.g., one or more LEDs) that may illuminate according to a defined lighting pattern. One or more cameras may capture images of a scene that includes the objects and the images may be analyzed to identify a location of each respective light source within the scene. By identifying these locations over multiple images, the movement of each object may be determined. In some instances, a system that tracks the movement of the objects may iterate through instructing each of the objects to illuminate its light source according to an identification lighting pattern, while other light source(s) of the other respective object(s) continue illuminating their light sources according to a default lighting pattern.
